For UK Plumbers

Boilers, breakdowns, big jobs – all in one app.

Built for plumbers running emergency callouts and bathroom fits side by side. Quote on the doorstep. Track time and parts. Send invoices that get paid. File HMRC MTD in one tap.

If you're a sole trader plumber,
some of this sounds familiar.

Graft was built specifically because none of the existing tools fit how a plumber actually works.

Quote vs callout – same WhatsApp thread

Emergency at 9am, bathroom quote at 2pm, customer wants to know when you're back. All mixed in messages, none of it tracked.

×

Parts margin guesswork

Pump cost £80, billed £120. Or was it £140? Margin per job is a vibe, not a number.

×

Invoices chased by hand

Customer says cheque's in the post. Three weeks later. You stop work to email them. Again.

×

MTD from April 2026

Quarterly tax submissions become legal. Spreadsheet plumbers will be hit hardest.

Plumbers & Making Tax Digital.

Do plumbers need Making Tax Digital software?

If your self-employed income is over £50,000 you must keep digital records and file quarterly updates to HMRC from April 2026 (the threshold drops to £30,000 in 2027). Graft keeps the records and files the returns from the same app.

What expenses can a self-employed plumber claim?

Van and fuel, tools, materials, Gas Safe registration, public liability insurance, workwear and business mileage at 45p per mile. Graft tags each cost to the job so nothing slips through the cracks.

Does Graft handle CIS for plumbers?

Yes. If you subcontract on new builds and have 20% CIS deducted at source, Graft records the deduction so your quarterly figures and year-end tax are correct.

Less than a pint a week.
