Made for your trade
Your books, kept from the van
A callout, three merchant runs and an emergency leak later, nobody's typing receipts into a spreadsheet. Photograph the receipt at the counter — Wolseley, City Plumbing, Screwfix — and SubReady records it before you're back in the van. Installs, servicing, bathrooms or heating, your records stay ready without an evening of admin.

Expenses plumbers should never miss
Plumbing eats materials and consumables. Make sure all of these end up in your books:
- Fittings, pipe, valves and boiler parts bought per job
- Gas Safe registration and annual renewal (heating engineers)
- Power tools, press tools, pipe benders and consumables
- Van running costs or mileage between jobs
- Public liability insurance and trade body fees
- Waste carrier licence and disposal costs
- Workwear, PPE and phone costs
CIS, handled
CIS for plumbers
New-builds and site work usually mean CIS: 20% deducted from labour (not materials) before you're paid. Domestic customers don't deduct anything — SubReady handles both side by side, keeps every CIS statement you forward, and tracks the deductions that become your year-end refund.
