Top 5 Electrician Apps Every UK Spark Should Know 

Mobile phones and tablets have become as essential on site as a multimeter or set of screwdrivers. For electricians, the right apps can save hours of admin, reduce errors, and even help win more work. From certification to cable calculations, there are now dozens of tools aimed at making the trade more efficient. 

At Elec Training, we work with learners at all stages — from beginners on Electrician Courses Shrewsbury to experienced installers working towards their NVQ portfolios. One question we’re often asked is: what digital tools should I be using once I’m on site? To answer that, we’ve rounded up the top electrician apps in the UK. 

1 – iCertifi (iOS only)

Certification is a big part of the trade, especially once you’re working towards the NVQ Level 3 and ECS Gold Card. iCertifi is designed to make paperwork easier by generating professional BS 7671 c ertificates directly on your phone or tablet. 

• Works fully offline (no need for Wi-Fi or 4G on site). 

• Produces secure PDFs that can be emailed or stored instantly. 

• Eliminates the need for carbon pads or laptops. 

It’s exclusive to Apple devices, but if you’re an iPhone or iPad user this app can save serious time. 

2 – QuickBooks Self-Employed (iOS, Android, Web)

A large number of electricians in the UK work as sole traders. Managing invoices, expenses, and tax returns is a common pain point. QuickBooks Self-Employed makes the process more manageable. 

• Track invoices and payments in real time. 

• Monitor expenses with digital receipts. 

• Integrates directly with HMRC’s self-assessment system. 

For those setting up after training, especially learners completing Electrician Courses Walsall and moving into self-employment, QuickBooks can feel like a virtual accountant in your pocket. 

3 – Megger Cable Calculator+ (iOS only)

Megger’s reputation in the electrical world is second to none, and their Cable Calculator+ app is a handy free tool. 

• Includes cable selection and volt-drop calculators. 

• Works for installations up to 25 kW / 100 A. 

• User-friendly interface ideal for quick checks on site. 

It doesn’t replace the need for proper design calculations, but for sparks balancing speed and accuracy, it’s a useful companion. 

4 – ElectroDroid (Android, iOS Pro version)

Originally released for Android, ElectroDroid has become a favourite among learners and seasoned electricians alike. 

• Free version (Android only) includes specs, formulas, and calculators. 

• Pro version (available on iOS too) adds more advanced features like LM317 regulator and voltage drop calculators. 

• Excellent for quick lookups when you don’t want to carry reference books everywhere. 

For trainees studying towards Level 3 or p reparing for inspection and testing, it’s a convenient way to double-check figures. 

5 – Energy Cost Calculator (iOS & Android)

Running costs matter, whether you’re quoting for a domestic rewire or helping a business reduce energy use. 

• Calculate consumption per hour in watts/kilowatts. 

• Estimate costs based on usage time. 

• Helps track CO₂ emissions for eco-friendly projects. 

Combine it with QuickBooks or another expense tracker, and you’ll have a clearer picture of your operating costs as a self-employed electrician. 

Why Apps Matter for Modern Electricians 

The industry is shifting rapidly. From smart home tech to green energy, electricians need to balance practical trade skills with digital awareness. These apps: 

• Save time — less paperwork, more tools in your pocket. 

• Boost professionalism — clients see polished reports and clear calculations. 

• Support compliance — staying aligned with BS 7671 and HMRC requirements. 

• Aid career progression — tools like iCertifi directly support NVQ evidence gathering. 

As you work through your training, think of apps as part of your kit. They won’t replace knowledge, but they will help you apply it efficiently. 

Elec Training’s Take 

At Elec Training, we believe in preparing learners for the real world of electrical work. That means not just passing exams, but understanding how to run jobs, manage paperwork, and keep on top of admin. 

For those starting with Electrician Courses Shrewsbury or Electrician Courses Walsall, we encourage you to get familiar with at least one or two apps early. As you progress towards the NVQ Gold Card route, these tools can make portfolio evidence simpler and site life smoother. 

Apps won’t make you an electrician — training, experience, and qualifications will. But they will make the day-to-day side of the job easier. Certification software, tax tools, calculators, and energy trackers all help electricians run efficient businesses and deliver better service.
