Tax & Money
What Can Self-Employed Electricians Claim on Tax UK 2026?
Most self-employed electricians claim far less on their tax return than they’re legally entitled to — not because they’re dishonest, but because nobody ever told them what HMRC actually allows.
Van and Vehicle Costs
Your van is almost certainly your biggest business expense. You need to choose a method from the start — you can’t switch mid-way through owning the vehicle.
Simplified mileage rate (most electricians use this): first 10,000 business miles at 45p/mile, then 25p/mile. 9,000 miles × 45p = £4,050 allowable deduction — roughly £810 less tax at the basic rate.
Actual cost method: claim fuel, insurance, servicing, repairs, road tax and MOT proportional to business use. More paperwork, sometimes higher if your van is almost exclusively for work.
Also claimable on top of either method: parking charges at job sites, toll fees and congestion charges. Not claimable: parking fines, and travel from home to your first job if home is your only base.
Tools and Equipment
Under the Annual Investment Allowance, claim 100% of the cost in the year of purchase, up to £1 million: hand tools, power tools, test equipment, ladders, van racking, site lighting, trunking cutters and conduit benders.
Materials and Consumables
Cable, consumer units, MCBs, RCDs, RCBOs, sockets, switches, conduit, trunking, fixings, tape, connectors — all fully deductible. Keep all supplier invoices.
NICEIC, NAPIT and Certification Fees
One of the most commonly missed categories: NICEIC or NAPIT annual registration, Part P notification fees, ECS card renewal, 18th Edition training, City & Guilds 2919 (EV charging), CPD courses, and CSCS cards where relevant.
Rule of thumb on training: maintaining or improving skills in your existing trade is claimable; training into a completely different career is not.
Protective Clothing and PPE
| Item | Claimable? |
|---|---|
| Steel-toecap boots | Yes |
| Hi-vis jackets and vests | Yes |
| Overalls and work trousers | Yes |
| Hard hat, safety glasses, knee pads | Yes |
| Regular jeans or trainers | No |
Phone, Broadband and Software
Claim the business-use proportion of your mobile bill (80% business use = claim 80%) and 30–50% of home broadband if you do admin from home. Software subscriptions — SparkyLog Pro, accounting software, quoting tools, cloud storage — are fully deductible.
Home as Office
HMRC flat rate: £10/month (25–50 hrs), £18/month (51–100 hrs), £26/month (101+ hrs) — or calculate the actual proportion of household costs.
Professional Fees and Insurance
Accountant fees, public liability insurance, tool insurance, van insurance (business proportion), business bank charges, and interest on a business loan — all claimable.
The Expenses Most Electricians Forget
Mileage · NICEIC/NAPIT annual fees · training and exam costs · business phone proportion · tool insurance · business bank charges · software subscriptions · home office allowance.
How to Keep Records That Satisfy HMRC
HMRC can investigate up to 4 years after submission — keep receipts, a mileage log, bank statements, and cash payment records. Log everything as you go rather than reconstructing a year’s worth in January. See the full walkthrough of every category in How to Claim Back More Tax as a Self-Employed Electrician.
