Why labour and materials go on separate lines
Most trade invoices that get queried are queried for the same reason: a single lump sum that the customer cannot break down. Splitting labour, materials and the call-out fee onto separate lines solves it in one step — the customer can check the hours against the job and the parts against the cost, and each part can be approved without touching the other.
- Labour — hours or days at your agreed rate.
- Materials — parts and fittings, listed so the customer can see what was fitted.
- Call-out fee — your charge for attending, where you make one.
- Extras — anything outside the agreed scope, on its own line.
Reference the job number, address or purchase order the customer gave you. Landlords, letting agents and main contractors pay against a reference, and an invoice without one sits in a shared inbox until someone chases it.
Working as a subcontractor under CIS
If you take on construction work for a contractor, you may be paid under the Construction Industry Scheme. You bill your gross amount as normal, and the contractor deducts CIS tax before paying you. You are not issuing a CIS invoice as such — you issue a normal invoice showing your gross labour and materials, and the contractor's deduction and the monthly CIS statement are their side of the arrangement. If you are VAT-registered, remember the deduction applies to the labour element, not the VAT. Keep every statement you receive.
VAT for plumbers and heating engineers
Only VAT-registered businesses charge VAT. If you are registered, tick the VAT box to add your VAT number and the rate, and the invoice will show the net, VAT and gross totals that a VAT invoice needs. Some energy-saving materials and qualifying installations are charged at the reduced 5% rate, so set the correct rate on each line rather than defaulting everything to 20%. If you are not registered, leave the box unticked and no VAT appears.

Frequently asked questions
What should a plumber invoice include?
Your name and any trading name, your address, a unique invoice number, the job date and invoice date, the customer name and the job or PO reference, labour, materials and any call-out fee itemised separately, the total and your payment details. VAT only if you are VAT-registered.
Should I separate labour and materials?
Yes. Separate lines let the customer check the hours and the parts independently, and each part can be approved without you having to reissue the whole invoice.
How does CIS affect a plumber invoice?
If you work as a subcontractor on construction work, the contractor may pay you under the Construction Industry Scheme, deducting CIS tax from your gross labour. You still issue a normal invoice; the deduction and the monthly CIS statement come from the contractor.
Do plumbers charge VAT on materials?
If you are VAT-registered, VAT normally applies to both labour and materials you supply, with some energy-saving installations at the reduced 5% rate. If you are not registered, do not charge VAT at all.
