Builders Invoice Template - UK

UK builders typically use stage invoicing for larger projects. Invoice at key completion points: after deposits, following groundwork, at structural completion, during finishing trades, and on final handover. This protects both you and the client. For smaller projects, you may invoice upon completion or in two stages (50/50 split). Always clarify the invoicing schedule in your initial quote or contract. This approach improves cash flow while maintaining trust with clients who prefer paying incrementally rather than upfront.

UK construction services are subject to 20% VAT. Include the VAT amount separately on your invoice with the line 'VAT at 20%'. Calculate VAT on the total labor and materials before deductions. You can only claim VAT back if you're VAT-registered. If you're not registered (under the £90,000 threshold), you cannot charge VAT, but you also cannot reclaim it. Always clearly state your VAT registration number if registered. Reverse charge rules may apply for certain commercial construction work.

UK construction commonly uses stage payment terms with retention clauses. A typical structure is payment due within 14 days of invoice (Net 14). Many clients retain 5-10% of each invoice until project completion, protecting themselves against defects. Larger projects often use 30-day terms (Net 30). Clarify payment terms in your initial quotation and include them clearly on every invoice. Consider offering a small discount for early payment (e.g., 2/10 Net 30) to encourage faster settlement and improve your cash flow.

Yes, separating materials from labor makes invoices clearer and more professional. List each trade separately: foundations, brickwork, plumbing, electrical work, plastering, and so on. This transparency helps clients understand costs and supports VAT calculations. For material-heavy projects, break down suppliers' costs alongside your labor charges. If you're supplying materials on behalf of the client, clearly mark these as reimbursables. Detailed line items reduce disputes and make future cost tracking easier. This approach also simplifies accounting and project management, especially for multi-trade projects.

Variations and extras should be invoiced separately from the original quote. Request written agreement from the client before proceeding with additional work—use a variation order or change notice. Invoice the extra work as a separate line item or supplementary invoice, clearly labeled 'Variation Order No. X' or 'Extra Works.' Include the original authorization reference so the client understands what they're paying for. Never assume consent; always confirm scope and cost in writing first. This protects you legally and prevents payment disputes over unexpected charges.

Yes, you can charge for site-related expenses, but they must be reasonable and agreed beforehand. Common chargeable items include: site setup and cleanup, temporary facilities (welfare, security), travel time for rural jobs, site surveys, and scaffolding hire. Include these as separate line items on your invoice so costs are transparent. Some clients expect travel to be absorbed, so clarify this in your quotation. Always document these costs properly for VAT purposes. Overhead recovery should be discussed upfront—surprised clients delay payment, so transparency prevents disputes.

Deposits are common in UK construction and protect your cash flow. A typical deposit is 25-50% of the total project cost, collected before work begins. Document the deposit clearly on your invoice, marking it as 'Deposit Received' and deducting it from the total due. Issue a receipt confirming the deposit amount and what work it covers. Deposits are not income until work is completed, so account for them correctly in your books. Always include deposit terms in your quotation and contract to prevent misunderstandings.

Multi-phase projects require clear invoicing by completion stage. Create a separate invoice for each phase or milestone: Phase 1 (Groundworks), Phase 2 (Structural), Phase 3 (First Fixes), Phase 4 (Finishing), and Phase 5 (Snagging). Each invoice should reference the project name, invoice number, and which phase it covers. Link invoices to your original quotation so the client sees how costs align with the agreed scope. This stage-based approach allows clients to retain portions until each phase is inspected and approved, protecting both parties.
