Ask any sparky what the worst part of the job is and it will not be crawling through a loft in August or chasing a ring final fault at 4pm on a Friday. It will be the admin. Certificates, wholesaler receipts, mileage, quotes, invoices — a second unpaid job that starts when the tools go back in the van. If you have ever searched for an electrician admin app in the UK and given up at the fourth pricing page, this one is for you.
The electrician's admin problem is different
Electrical work is certificate-heavy in a way most trades are not. An EICR, an EIC, a minor works certificate — every notifiable job generates paperwork that has to be right, because your name and registration number sit on it. That part you already handle, because you have to. It is everything around the certificates that quietly rots: the receipts, the miles, the quotes you meant to send on Tuesday.
The pattern is familiar. You are at the wholesaler counter at 7.30am with a trade account and a trolley. The receipt goes in a pocket, the pocket goes through the wash, and three months later your accountant asks why your materials costs look thin for someone who rewired four kitchens that quarter. Every receipt you lose is profit you pay tax on as if it never existed.
The morning wholesaler run is a receipt machine
Most electricians hit the wholesaler every working morning, and often again at lunch when the job turns out to need a different RCBO. That is five to ten receipts a week minimum — twine, glands, a length of 10mm twin and earth, a consumer unit, clips, tape. Individually trivial. Across a year, thousands of pounds of deductible cost.
The fix is not discipline, it is friction removal. The moment the receipt hits your hand, photograph it. If your system requires you to then open an app, create an expense, pick a category and attach the photo, you will stop doing it by Wednesday. The systems that survive are the ones where the photo is the filing. The principle is simple: capture at the counter, sort never.
Van mileage between jobs adds up faster than you think
A domestic electrician doing two or three jobs a day, plus wholesaler runs, plus the odd quote visit, can easily cover 12,000 to 18,000 business miles a year. Under HMRC's approved mileage rates, a sole trader can claim 45p per mile for the first 10,000 business miles in a car or van, and 25p per mile after that. On 15,000 miles that is £5,750 of allowable expense — if you have the records. Guess at year end and you will guess low, because nobody dares guess high. A quick note per trip — postcode to postcode, job name — is all the record needs to be. There is a fuller breakdown in our guide to mileage tracking for UK tradespeople. As ever, confirm the details with your accountant.
Quoting a consumer unit swap from a photo
Half the quotes an electrician sends start with a photo of an old board. The customer WhatsApps you a picture of a fuse box that predates decimalisation, you squint at it, count the ways out, spot the missing bonding, and price the swap. The quote itself is formulaic: board, breakers or RCBOs, SPD, tails if needed, bonding remedials, a day's labour, certification. You have priced a hundred of them.
So why does the written quote take until 9pm? Because it lives in a laptop workflow and your evening does not. The jobs that never get quoted are the jobs you never win. If you can turn that photo into a sent quote in the same ten minutes you spent assessing it, your conversion rate goes up for free — the fastest quote through the letterbox wins more often than the cheapest one.
Invoice the day the job is signed off
The best moment to invoice is the moment the customer is standing next to a working, certified installation, delighted the lights come on. Wait a week and the glow fades, the invoice becomes a bill like any other, and payment drifts. Electricians who invoice same-day get paid measurably faster than those who batch invoices on a Sunday night. The only reason not to do it is that your invoicing tool lives on a computer at home. Put invoicing in your pocket and same-day becomes the default, not the exception.
Where GraftG fits
This is the exact gap GraftG is being built for. It turns WhatsApp — the app already open on your phone all day — into a back office for UK tradespeople. Text a mileage note after each trip, photograph wholesaler receipts as they land, fire off a quote from the customer's photo of the old board, send the invoice while you are still parked outside, and keep a running job tracker of what is quoted, done and paid. No new app to download, no dashboard to learn. Your admin sorted, just WhatsApp it.
GraftG is coming soon, so you cannot use it on tomorrow's board change — but the habits above work today with nothing more than your camera and a notes app. Start capturing now; the tooling catches up shortly.
GraftG is launching soon for UK electricians and other trades. Join the waitlist at graftg.co.uk and be first in line when the number goes live — mileage, receipts, quotes, invoices and job tracking, all by WhatsApp.
