- Changes: Initial publication examining self-employment impact on electrician income, showing gross earnings typically 20-50% higher than PAYE but net take-home often similar (0-25% increase) after £7,000-£12,000 annual overheads, 20-30% CIS/umbrella deductions, 4-12 weeks downtime, 5-15 hours weekly unpaid admin, income quality analysis showing PAYE £38,000 package value £44,000-£46,000 vs self-employed £52,000 gross netting £43,000-£45,000 equivalent
Self-employment’s impact on electrician income requires examining the comprehensive analysis of electrician earnings across employment models distinguishing between gross turnover (total invoiced), business profit (after overheads), and net take-home pay (after tax/NI), because the common perception that “self-employed electricians earn significantly more” conflates gross day rates or hourly charges with actual disposable income. A PAYE electrician earning £38,000 annual salary takes home approximately £29,500 after tax and National Insurance with zero overhead costs, 28 days paid holiday (£4,200 value), 3-5% employer pension contribution (£1,140-£1,900 value), sick pay protection, and employer-funded training. A self-employed electrician charging £300/day achieving £60,000 gross turnover appears vastly superior until accounting for £7,000-£12,000 annual overheads (van, insurance, tools, compliance), £12,000-£15,000 tax/NI, self-funded holidays and training, resulting in £33,000-£41,000 net take-home—only 12-39% higher than PAYE despite 58% higher gross.
This gross-to-net transformation explains why electricians transitioning to self-employment often experience disappointment when elevated day rates (£300-£450) or hourly charges (£40-£60) don’t translate to proportional income increases. The transformation occurs through multiple erosion factors: overhead burden (£5,000-£15,000 annually depending on sector and business model), non-billable time consuming 20-40% of working hours (quoting, invoicing, admin, travel between jobs), downtime gaps (4-12 weeks annually between contracts or during seasonal slowdowns), utilization rates significantly below 100% (domestic electricians billing only 50-70% of available hours, commercial contractors 70-85%), CIS tax deductions (20% withheld at source for subcontractors), umbrella company fees (3-5% plus employer NI obligations reducing gross to net), and benefit value loss (self-funded holidays, sick pay gaps, pension underfunding).
The employment model choice—PAYE employee, CIS subcontractor, umbrella contractor, domestic sole trader, limited company director—creates different gross-to-net conversion patterns. PAYE demonstrates highest conversion efficiency (approximately 75-78% gross to net after tax/NI) with zero overhead absorption but capped earning ceiling. CIS subcontracting offers flexibility with 70-75% conversion after 20% deduction and moderate overheads. Umbrella arrangements appear attractive with high “assignment rates” but suffer lowest conversion (60-70%) due to employer NI, fees, and deduction stacking. Domestic sole traders achieve highest nominal hourly rates (£40-£60) but lowest utilization (50-70%) creating moderate conversion (65-75%). Limited companies enable tax efficiency for high earners (£60,000+ profit) through salary/dividend optimization but carry compliance costs and administrative complexity.
Career stage critically determines whether self-employment boosts or suppresses income. Newly qualified electricians (0-3 years post-qualification) transitioning to self-employment almost universally earn less net income than PAYE equivalents after accounting for slow working speed (tasks taking 2-3x experienced electrician time), lack of professional network (resulting in 8-16 weeks annual downtime), high business learning curve overhead (admin consuming 15-20 hours weekly initially), and low initial client base (requiring expensive marketing £2,000-£4,000 annually). Mid-career electricians (5-10 years experience) with established networks and commercial working speed typically see 20-35% net income increases going self-employed. Experienced specialists (10+ years, HV/CompEx/niche competencies) command premium rates (£350-£450/day) with efficient operations achieving 35-50% net increases.
Sector significantly impacts self-employment economics. Domestic installation work offers highest nominal rates (£40-£60/hour, £400-£600 per job) but suffers lowest utilization (50-70%) from lead generation overhead, quote-to-conversion ratios (need 3-4 quotes to win 1 job), travel time between small dispersed jobs, and customer schedule accommodations. Effective hourly rate often £20-£28 after total time accounting. Commercial contracting provides moderate day rates (£300-£400) with higher utilization (75-85%) working full days on single sites, achieving £24-£32 effective hourly. Industrial specialist work commands highest day rates (£350-£450) with 70-80% utilization (shutdown scheduling creates predictable gaps) delivering £28-£36 effective hourly—the self-employment premium concentrates here rather than domestic sector despite perception.
Understanding realistic self-employment income impact requires examining comprehensive overhead burden itemization (van £2,400-£4,800 annually, insurance £800-£1,500, fuel £1,800-£3,600, tools £1,000-£3,000, compliance £500-£2,000, marketing £1,000-£4,000 domestic), utilization rate reality modeling (billable hours as percentage of total working hours by sector), income quality framework (comparing total package value including benefits not just headline salaries), worked examples showing identical gross achieving different net outcomes based on employment model and overhead efficiency, CIS deduction mechanics (20% advance payment creating January tax bill shock), umbrella company fee structures, sector-specific conversion patterns, career stage optimization timing, and volatility quantification (self-employment income variability creating effective 10-20% discount versus PAYE stability value).
This analysis synthesizes ONS ASHE PAYE electrician median earnings (£39,039 2025 providing baseline comparison), HMRC CIS guidance on deduction mechanics and allowable expenses, government statutory holiday entitlement (5.6 weeks PAYE creating £3,000-£5,000 annual value self-employed must self-fund), JIB wage tables establishing PAYE floor rates (£21.00/hour 2027 Approved Electrician projection), market signal day rates from job boards and surveys (Logic4training average £335/day, Checkatrade £320, MyJobQuote £350-£450 ranges), and trade forum discussions revealing actual achieved earnings versus advertised rates. The analysis deliberately counters both unrealistic self-employment optimism (ignoring overhead and utilization realities) and unfounded negativity (missing genuine income premiums for experienced electricians in right sectors) with balanced evidence-based framework.
The Overhead Burden: Why £50,000 Turnover ≠ £50,000 Income
Self-employed electricians face comprehensive annual overhead costs that PAYE employees never directly experience because employers absorb these business operation essentials. Understanding true overhead burden explains why gross turnover must significantly exceed PAYE salary equivalents to deliver similar net take-home.
Thomas Jevons, Head of Training with 20+ years on the tools, explains:
"The £5,000-£15,000 annual overhead burden gets dramatically underestimated by electricians considering self-employment. Van lease or finance £200-£400 monthly, business insurance £800-£1,200, fuel £150-£300 monthly depending on domestic vs commercial work patterns, tool replacement £1,000-£2,000 annually from theft and wear, test equipment calibration £200-£400, professional body membership £300-£600, Part P notifications £3-£5 per domestic job, accountancy £600-£1,500. That's £7,000-£12,000 before you've earned a single pound. PAYE electrician earning £38,000 gross takes home approximately £29,500. Self-employed electrician needs £50,000-£55,000 turnover just to match that £29,500 take-home after covering overheads and self-funded tax/NI. The 'I'll charge £300/day so I'll earn £78,000 annually' calculation completely ignores this overhead floor that must be cleared before any profit materializes."

Overhead as Percentage of Turnover
Critical Insight:
Low turnover (£40,000): Overheads represent 25-48% of gross (domestic) or 13-27% (commercial)
Medium turnover (£60,000): Overheads represent 16-32% (domestic) or 9-18% (commercial)
High turnover (£80,000+): Overheads represent 12-24% (domestic) or 7-13% (commercial)
This scaling disadvantage explains why newly qualified or part-time self-employed electricians struggle—fixed overhead costs consume disproportionate percentage of lower turnover, requiring higher volume to achieve overhead efficiency.
Utilization Reality: Why You're Not Billing 40 Hours Weekly
The gap between available working hours and actually billable hours represents perhaps the largest income suppression factor distinguishing self-employment from PAYE, where employees bill effectively 100% of contracted hours (employer absorbs admin, training, downtime).
Billable vs Non-Billable Time Breakdown
PAYE Electrician (40-hour week baseline):
On-site productive work: 37-38 hours (92-95%)
Toolbox talks/safety meetings: 1-2 hours (employer-paid)
Training/CPD: 1 hour (employer-paid)
Effective billable rate: 92-95% of contracted hours
CIS Commercial Contractor (40-hour target week):
On-site billable work: 32-34 hours (80-85%)
Travel to/from site: 3-4 hours (typically unpaid unless distant)
Invoicing and admin: 2-3 hours (unpaid)
Quote preparation and estimating: 1-2 hours (unpaid)
Effective billable rate: 70-85% of working hours
Domestic Sole Trader (40-hour target week):
On-site billable work: 20-28 hours (50-70%)
Travel between multiple jobs: 5-8 hours (unpaid, high windshield time)
Quoting and customer consultations: 4-8 hours (quote 3-4 jobs to win 1)
Invoicing, payment chasing, admin: 3-5 hours (unpaid)
Marketing and lead generation: 2-4 hours (unpaid)
Material collection and returns: 2-3 hours (partially billable via markup)

Umbrella Contractor (37.5-hour week baseline):
On-site billable work: 30-34 hours (80-90%)
Compliance and timesheet processing: 2-3 hours (paid as part of assignment)
Travel and breaks: 2-4 hours (partially paid)
Effective billable rate: 75-85% of working hours
Impact on Effective Hourly Rates
Example Calculation: £300 Day Rate CIS Contractor
Optimistic Scenario (High Utilization):
Works 46 weeks annually (allowing 4 weeks holiday, 2 weeks gaps)
Bills 34 hours weekly (85% utilization)
Total billable hours: 1,564 annually
Spends additional 6 hours weekly unpaid admin/travel
Total working hours: 1,840 annually
Gross earnings: £300/day × 5 days × 46 weeks = £69,000
Effective hourly rate: £69,000 ÷ 1,840 hours = £37.50/hour
After £8,000 overheads and £15,000 tax/NI: £46,000 net = £25/hour effective
Realistic Scenario (Moderate Utilization):
Works 42 weeks annually (4 weeks holiday, 6 weeks gaps between contracts)
Bills 30 hours weekly (75% utilization)
Total billable hours: 1,260 annually
Spends additional 8 hours weekly unpaid (admin, quoting, gaps)
Total working hours: 1,680 annually
Gross earnings: £300/day × 5 days × 42 weeks = £63,000
Effective hourly rate: £63,000 ÷ 1,680 hours = £37.50/hour
After £8,000 overheads and £13,500 tax/NI: £41,500 net = £24.70/hour effective
Example Calculation: £50/hour Domestic Sole Trader
Optimistic Scenario (High Utilization for Domestic):
Works 44 weeks annually
Bills 28 hours weekly (70% utilization – high for domestic)
Total billable hours: 1,232 annually
Spends additional 12 hours weekly unpaid (quoting, marketing, admin, travel)
Total working hours: 1,760 annually
Gross earnings: £50/hour × 1,232 hours = £61,600
Effective hourly rate: £61,600 ÷ 1,760 hours = £35/hour
After £12,000 overheads and £13,000 tax/NI: £36,600 net = £20.80/hour effective
Realistic Scenario (Moderate Utilization):
Works 42 weeks annually (includes seasonal slowdowns)
Bills 24 hours weekly (60% utilization – typical domestic)
Total billable hours: 1,008 annually
Spends additional 14 hours weekly unpaid
Total working hours: 1,596 annually
Gross earnings: £50/hour × 1,008 hours = £50,400
Effective hourly rate: £50,400 ÷ 1,596 hours = £31.60/hour
After £12,000 overheads and £10,000 tax/NI: £28,400 net = £17.80/hour effective
Why Utilization Varies by Sector
Commercial Contracting (70-85% typical):
Single site reduces travel overhead
Full 8-10 hour days standard
Agency handles client acquisition
Predictable scheduling
Lower quote-to-win ratio (agencies pre-qualify)
Industrial Contracting (70-80% typical):
Shutdown scheduling creates known gaps
High-value long-duration projects
Minimal marketing needed
Travel/lodging compensated
Professional client base pays reliably
Domestic Installation (50-70% typical):
Multiple small jobs requires constant travel
Quote 3-4 jobs to win 1 (high unpaid time)
Customer schedule accommodations (evenings, weekends)
Lead generation overhead
Payment chasing and bad debt
Material collection trips between jobs
Income Quality vs Income Quantity: Total Package Value
Comparing self-employment to PAYE purely on gross or even net income figures ignores substantial value differences in benefit packages, income stability, risk absorption, and lifestyle quality—the total compensation package extends beyond headline salary numbers.
Joshua Jarvis, Placement Manager at Elec Training, explains:
"When advising electricians considering self-employment, we discuss income quality not just quantity—the reliability, predictability, and benefit package value often matters more than gross figure differences. PAYE electrician earning £38,000 receives that amount in 12 predictable monthly payments, continues receiving 80% during 4-week flu bout via sick pay, gets 28 days paid holiday worth £4,200 annual value, receives 3-5% employer pension contribution £1,140-£1,900, benefits from employer-paid training £500-£1,500 annually, and gains death-in-service coverage potentially £100,000+ benefiting family. Total package value approximately £44,000-£46,000 with zero volatility or downside risk. Self-employed earning £52,000 gross sounds significantly better. But after £8,000 overheads, £12,000 tax/NI, self-funded holiday and training, zero sick pay during that same flu bout costing £2,400 lost earnings, and paying £1,200 for income protection insurance, net package value approximately £43,000-£45,000 with high volatility and personal risk absorption. The £8,000 gross advantage becomes £0-£2,000 net advantage when comparing equivalent quality. Self-employment makes sense for risk-tolerant individuals optimizing for peak earning years 35-50, less so for those prioritizing stability, family security, or approaching retirement."
PAYE Total Package Valuation
Base Salary: £38,000 example
Hidden Value Components:
Paid holiday (28 days = 5.6 weeks): £4,200 annual value (£38,000 ÷ 46.4 working weeks = £819/week × 5.6 weeks)
Employer pension contribution (3-5%): £1,140-£1,900 annually
Employer National Insurance (13.8% on salary above £9,100): £3,988 annually (employer cost, not direct benefit but tax-efficient employment structure value)
Sick pay protection (SSP minimum, often enhanced): £500-£1,500 annual expected value
Employer-funded training and CPD: £500-£1,500 annually
Death-in-service benefit (2-4x salary typical): £76,000-£152,000 coverage value (actuarial value £400-£800 annually)
Private medical insurance (some employers): £0-£1,200 annually
Tool and equipment provision: £500-£1,000 annual value (employer maintains)
Total Package Value: £44,828-£50,088 Gross to Total Package Multiplier: 1.18-1.32x
Income Characteristics:
Predictability: 12 equal monthly payments, zero volatility
Stability: Continues during illness, economic downturns
Risk: Employer bears business risk, economic cycle exposure
Lifestyle: Clear work/life boundary, no admin burden
Self-Employed Total Package Valuation
Gross Turnover: £52,000 example (equivalent CIS contractor £300/day, 43 weeks)
Cost Deductions:
Overheads (vehicle, insurance, tools, compliance, admin): £8,000
Tax and NI (Income Tax + Class 2/4): £10,000-£12,000
Self-funded holiday (6 weeks unpaid equivalent): £0 (lost earnings)
Self-funded training: £500-£1,000
Income protection insurance (to replace sick pay): £800-£1,200
Accountancy: £800-£1,200
Net Package Value: £29,000-£32,000
Additional Considerations:
Holiday opportunity cost: 6 weeks unpaid = £3,600 (£600/week × 6) foregone earnings
Sick leave opportunity cost: No SSP, any illness = immediate income loss
Pension: Self-funded (often underfunded), no employer matching
Death-in-service: Must purchase life insurance privately £30-£100/month (£360-£1,200 annually) for equivalent coverage
Adjusted Total Package Value: £32,000-£38,000 Gross to Total Package Multiplier: 0.62-0.73x
Income Characteristics:
Predictability: High volatility, uneven cashflow
Stability: Immediately ceases during illness or gaps
Risk: Individual bears all business risk
Lifestyle: Work bleeds into personal time, constant admin
Equivalent Gross Requirement Calculation
For self-employed electrician to match PAYE £38,000 total package value (£44,828-£50,088):
Required Gross Turnover:
Target net package value: £45,000
Add back overheads: £8,000
Add back tax/NI: £10,500-£12,000
Add self-funded benefits value: £5,000-£6,000
Required gross turnover: £68,500-£71,000
Conversion:
At £300/day: 45.7-47.3 weeks of 5-day working (accounting for utilization, requires 54-56 available weeks including downtime)
At £350/day: 39.1-40.6 weeks of 5-day working
Practical reality: Very difficult to achieve equivalent quality match at typical CIS rates
Risk-Adjusted Value Discount
Financial theory suggests income volatility and risk should be discounted relative to stable equivalent. The appropriate discount rate for self-employment income:
Conservative Approach: 10-15% volatility discount
Self-employed £45,000 gross treated as equivalent to PAYE £38,250-£40,500 when accounting for income uncertainty, gap risk, and stress value
Moderate Approach: 15-20% discount
Self-employed £45,000 gross equivalent to PAYE £36,000-£38,250
This explains why many electricians report higher self-employed earnings but don’t “feel” significantly better off—the risk burden, volatility stress, and admin overhead create psychological and practical value erosion beyond numerical income comparison.
Employment Model Comparison: PAYE, CIS, Umbrella, Sole Trader
Different self-employment structures create distinct gross-to-net conversion patterns, overhead burdens, and administrative complexities. Understanding these differences prevents model selection errors that suppress rather than boost income.

WARNING: Many electricians accept umbrella roles believing £400/day assignment rate means £400/day take-home, discovering actual gross pay £260-£280/day after umbrella deductions—a 30-35% immediate reduction before personal tax.
Domestic Sole Trader
Structure: Self-employed individual running own domestic electrical installation/maintenance business, trading under own name
Income Mechanics:

Common Myths About Self-Employment Income
Myth 1: “Self-Employed Always Earn More”
Reality: Gross earnings typically 20-50% higher, but net take-home often only 0-25% higher after £7,000-£12,000 overheads, 20-30% deductions, downtime, and benefit value loss. Early-career domestic electricians frequently earn less self-employed than PAYE equivalents.
Myth 2: “Day Rate Equals Take-Home”
Reality: £300/day gross becomes £180-£220/day net effective after 20% CIS deduction, overheads, unpaid admin time, and downtime gaps. The £300 “daily” rate is achieved only 70-85% of available working hours.
Myth 3: “Umbrella Assignment Rates Are What You Earn”
Reality: £400/day assignment rate includes employer NI (13.8%), umbrella fees (3-5%), and holiday pay (12.07%)—actual gross pay to worker only £260-£280/day, then subject to personal tax/NI. Assignment rate 30-35% higher than actual earnings.
Myth 4: “You Can Claim Everything as an Expense”
Reality: HMRC allows only expenses “wholly and exclusively” for business. Cannot claim: personal mileage, meals unless overnight business travel, clothing unless hi-vis/PPE, phone bills unless separate business line. Aggressive claiming triggers investigations.
Myth 5: “Limited Company Avoids Tax”
Reality: Still pay via salary (PAYE) and dividends (dividend tax). Corporation Tax 19-25% on company profits, then dividend tax 8.75-39.35% on extraction. Tax efficiency exists for £60,000+ profit but not “tax avoidance”—saves perhaps 5-10% versus sole trader at higher admin cost.
Myth 6: “No Downtime If You’re Good”
Reality: Even experienced contractors with strong networks face 4-8 weeks annual downtime from contract gaps, shutdown scheduling, seasonal slowdowns, and deliberate holiday periods. Domestic traders face 8-12 weeks in quiet winter months.
Myth 7: “Self-Employment Means Working Less”
Reality: Most self-employed work 45-55 hours weekly including admin, compared to PAYE 37.5-40 contracted hours. The “flexibility” often means working evenings and weekends to accommodate customers or complete quotes.
Myth 8: “Marketing Is Free Word-of-Mouth”
Reality: Domestic electricians spend £1,500-£4,000 annually on Checkatrade memberships, Google Ads, van signage, business cards, website hosting. Word-of-mouth takes 3-5 years to build, requiring paid lead generation initially.
Myth 9: “CIS 20% Deduction Is Total Tax”
Reality: CIS withholds 20% as advance payment. Actual tax liability—Income Tax plus Class 2 and Class 4 NI—often 28-35% of profit. January self-assessment commonly requires additional £3,000-£6,000 payment, shocking those who assumed CIS covered everything.
Myth 10: “Tools Are One-Time Cost”
Reality: Ongoing replacement £1,000-£3,000 annually from wear, damage, theft. Test equipment calibration £150-£400 annually mandatory. Power tool batteries £200-£400 annual replacement. UK tool theft rates mean insurance excess £200-£500 per claim, multiple claims annually common.
Myth 11: “Domestic Rates (£50/hour) Mean High Income”
Reality: Billing only 24-28 hours weekly (60-70% utilization) due to quoting, marketing, travel creates £50,000-£65,000 gross. After £12,000-£15,000 overheads and tax, net £28,000-£38,000—similar to PAYE £35,000-£42,000 working fewer hours.
Myth 12: “Industrial Always Pays Best”
Reality: Industrial day rates £350-£450 highest, but travel/lodging costs £2,000-£4,000 annually, time away from family, and physical demands make it unsuitable for everyone. Commercial £300-£350 with local work often delivers better lifestyle-adjusted value.
Myth 13: “Pension Doesn’t Matter When Young”
Reality: PAYE electrician age 25-65 with 3% employer contribution (£1,200 annually) accumulates approximately £180,000-£250,000 pension pot (assuming 5% growth). Self-employed neglecting pension faces £180,000-£250,000 retirement shortfall requiring private savings discipline rarely achieved.
Myth 14: “Bad Debt Is Rare”
Reality: Domestic electricians experience 2-5% non-payment (£1,000-£4,000 on £50,000 turnover). Commercial contractors 1-2% but on larger invoices. Payment chasing consumes 2-4 hours monthly, small claims court sometimes necessary.
Myth 15: “Accountants Are Too Expensive”
Reality: Good accountant £800-£1,500 annually saves that amount via legitimate deductions, tax planning, and avoiding HMRC penalties. Bad accountant or DIY approach costs more in missed deductions, errors, and time spent on admin.
Data Limitations and Forecast Uncertainty
ONS Data Gaps for Self-Employed Income
ASHE (Annual Survey of Hours and Earnings) provides robust PAYE electrician salary data (£39,039 median 2025) but excludes self-employed entirely, understating true average electrician income and obscuring self-employment earnings distributions. ONS self-employment income data aggregates construction sector broadly without electrician-specific breakdowns, and may understate actual earnings due to cash-job under-reporting.
Market Signal Reliability Issues
Job board day rates (£300-£450 advertised) represent asking prices not achieved rates—actual negotiations, downtime, and overhead often reduce effective earnings 20-35% below advertised. Survey data (Logic4training £335/day average, Checkatrade £320) useful directionally but limited sample sizes (self-selecting high earners likely over-represented) and regional variations not captured.
Regional and Sector Variations
London rates 20-30% higher than presented averages (£380-£500/day commercial contractor common), while rural Wales/Scotland 20-30% lower (£220-£280/day). Domestic vs commercial vs industrial sector variations create £15,000-£25,000 annual outcome spreads not captured in aggregate figures. Specialist niches (EV, solar, smart homes) command premiums but too small sample to quantify reliably.
Tax and Deduction Complexity
CIS deduction rates, umbrella fee structures, and allowable expense interpretations vary by individual circumstances—presented figures represent typical ranges but actual outcomes depend on specific business activities, accountant quality, and HMRC relationship. IR35 legislation creates additional complexity for limited company contractors working through intermediaries, potentially reclassifying as deemed employees.
Overhead and Utilization Estimates
Presented overhead costs (£5,000-£15,000) based on market signals and trade forum discussions rather than verified accounting data—actual costs vary significantly by business model efficiency, geographic location, sector, and individual purchasing decisions. Utilization rates (50-85%) represent informed estimates from recruiter feedback and contractor discussions, not time-tracking studies—individual variation high based on business maturity and network strength.
If you’re considering transition to self-employment or evaluating whether your current self-employed income genuinely exceeds equivalent PAYE value, call us on 0330 822 5337 to discuss detailed breakdown of electrician pay across PAYE, contractor, and self-employed pathways specific to your experience level, sector positioning, family circumstances, and risk tolerance—helping you avoid the common trap of pursuing higher gross earnings that deliver lower net package value. The Elec Training’s complete guide to electrician career earnings provides comprehensive context on employment model optimization, showing how strategic choices about PAYE versus self-employment timing, sector selection, and overhead management determine whether self-employment boosts income 30-50% or suppresses it 10-20% below PAYE equivalents.

Note on Accuracy and Updates
Last reviewed: 5 January 2026. This page is maintained; we correct errors and refresh sources as HMRC guidance, ONS data releases, umbrella company regulations, and market day rates change. Self-employment impact analysis uses comprehensive overhead itemization (£5,000-£15,000 annually varying by business model: CIS commercial £5,200-£10,600, domestic sole trader £9,600-£19,000 highest due to marketing costs), utilization rate modeling (PAYE 92-95% effective billable, CIS commercial 70-85%, domestic sole trader 50-70% lowest from quoting/marketing/travel overhead), income quality framework showing PAYE £38,000 total package value £44,000-£46,000 with benefits vs self-employed £52,000 gross netting £43,000-£45,000 equivalent quality after £8,000 overheads and £12,000 tax/NI, employment model gross-to-net conversions (PAYE 76-77% most efficient, CIS 64-67%, umbrella 71% of assignment rate but only 57-59% including hidden deductions, domestic sole trader 43-62% lowest due to low utilization), worked examples showing identical qualifications creating £22,936-£45,420 net outcomes (PAYE £32,161 middle, CIS £45,420 highest but no pension/benefits, domestic £22,936 lowest from utilization trap). Critical findings: self-employed requires £50,000-£55,000 gross turnover to match PAYE £38,000 package value (£29,500 take-home), early-career electricians (0-3 years) typically earn less self-employed than PAYE due to slow speed and weak networks, mid-career (5-10 years) see 20-35% genuine net increases, domestic nominal rates £40-£60/hour deliver only £18-£22 effective hourly after utilization accounting, umbrella assignment rates misleading (£400/day includes employer NI/fees/holiday reducing actual gross to £260-£280/day pre-tax), CIS 20% deduction not total tax liability (additional £2,000-£6,000 January bill common), income quality analysis shows risk-adjusted £45,000 self-employed equivalent to £38,000-£40,500 PAYE when volatility valued. Data limitations acknowledged: ONS excludes self-employed from ASHE, market day rates are asking not achieved prices, overhead costs vary significantly by efficiency and location, utilization rates estimated from recruiter feedback not time-tracking studies, individual outcomes highly variable based on network strength and business maturity. This is analysis framework not financial/tax advice—consult qualified accountant and financial advisor for personal circumstances. Next review scheduled following HMRC CIS/umbrella guidance updates, ONS self-employment income data release 2026, and quarterly market rate surveys.
