Best Free App for Self-Employed Electricians UK 2026

Updated June 2026 · 9 min read · SparkyLog Team

If you’re a self-employed electrician in the UK, you’re probably running your business from a notebook, WhatsApp, and memory. It works — until January comes around and you’re scrambling to reconstruct a year’s worth of expenses.

What a Self-Employed Electrician Actually Needs

Job records (who, what, where, when), professional quotes with your NICEIC or NAPIT number, invoices, mileage tracking at the HMRC rate, expense logging, and a year-end summary. Not on the list: GPS dispatch, multi-engineer scheduling, customer portals, CRM pipelines.

The NICEIC and NAPIT Problem

As a registered electrician you’re legally required to include your NICEIC or NAPIT number on certification documentation, and it should appear on invoices and quotes too. Most generic apps have no field for this — you end up adding it manually, or leaving it off entirely. SparkyLog includes a dedicated field that appears automatically on every Pro invoice and quote.

The Mileage Problem

HMRC allows 45p per mile for the first 10,000 business miles (25p after). For a self-employed electrician covering a reasonable area, that’s often £3,000–£5,000 a year.

App Comparison

SparkyLog — Built for UK Sole Trader Electricians

Browser-based, no download. Free plan: 10 jobs/month, no credit card, no trial expiry. Pro at £9.99/month: unlimited jobs, professional invoices with NICEIC/NAPIT number, HMRC-rate mileage, full expense logging, and a tax report summarising income, expenses, mileage and profit.

Making Tax Digital — What Electricians Need to Know

MTD for Income Tax applies from April 2026 for income over £50,000, and from April 2027 for income over £30,000— requiring digital record-keeping and quarterly reporting instead of a single annual return.

What Tradify and Jobber Get Wrong for Sole Traders

Price (£39–49/month is significant for a one-person operation), complexity (dispatch/scheduling features for multi-engineer teams), no UK tax integration, and no NICEIC/NAPIT field. See the full three-way comparison in SparkyLog vs Tradify vs Jobber.

What About QuickBooks or Xero?

Accounting packages, not job management tools. They track income and expenses well but won’t create a job record tied to materials, generate a NICEIC-numbered invoice, or log mileage at the HMRC rate automatically. Some electricians use both — a job app plus an accounting package.

The Honest Answer

Doing 10 or fewer jobs a month and not tracking anything: start with SparkyLog’s free plan. Doing more, or want NICEIC-numbered invoices: SparkyLog Pro at £9.99/month. Running a team of three or more: look at Tradify.
