Stage Payment Best Practices

Keep the deposit reasonable

10-15% is standard for larger projects. This should cover initial material purchases and mobilisation. Asking for too much upfront can make customers uncomfortable and suggests poor cash flow management.

Tie payments to milestones, not dates

Stage payments should be triggered by reaching specific project milestones (e.g. "foundations complete") rather than calendar dates. This protects both parties -- the customer only pays for completed work, and you get paid when you deliver.

Put it in writing

Always include the payment schedule in your written contract or proposal. Clearly state the milestone, the percentage/amount due, and the payment terms (e.g. payable within 7 days of milestone completion). This prevents disputes later.

Hold back a retention

For larger projects, consider holding back 5-10% as a retention payment, payable after a snagging period (typically 2-4 weeks after completion). This gives the customer confidence that any issues will be addressed, and motivates you to complete the snagging list promptly.

Stage Payments for UK Construction Projects

Stage payments are the standard way to manage cash flow on building projects in the UK. They protect both the builder and the customer by ensuring payments are tied to completed work, rather than paid entirely upfront or entirely on completion.

Why Stage Payments Matter

For builders, stage payments maintain healthy cash flow throughout a project. Material costs, labour and overheads do not wait until the end of a project -- so your income should not either. For customers, stage payments mean they are never significantly ahead of the work completed, reducing their risk if something goes wrong.

Typical Payment Structures

The right payment structure depends on the size and complexity of the project:

  • Small jobs (under £5,000) -- 3 stages: deposit (25-30%), midway (40-50%), completion (25-30%)
  • Medium projects (£5,000-£25,000) -- 4 stages: deposit (10-15%), after structural work (30-35%), after first/second fix (30-35%), completion (15-20%)
  • Large projects (£25,000+) -- 5+ stages tied to specific milestones with a retention payment

Including Payment Terms in Your Proposals

Professional proposals should always include a clear payment schedule. This builds trust with customers and sets expectations from the start. Use tools like QuoteSmith to generate professional proposals with built-in payment schedules, milestone descriptions, and terms -- giving your customers confidence in how the project will be managed financially.

Frequently Asked Questions

Common questions about stage payments and payment schedules for builders.

What is a typical payment schedule for building work?

A common schedule is 10-15% deposit upfront, then stage payments at key milestones (foundations, first fix, second fix), and a final payment of 5-10% on completion and snagging sign-off. For smaller jobs under £5,000, a simpler 3-stage plan works well: deposit (25-30%), midway (40-50%), completion (25-30%).

How much deposit should a builder ask for?

10-15% is standard for most building projects. This covers initial material purchases and mobilisation costs. Some tradespeople ask up to 25% for smaller jobs. Be cautious of asking for more than 25% upfront, as this is often seen as a red flag by customers and consumer protection organisations.

Should I use stage payments or pay on completion?

For any project over £1,000-2,000, stage payments are strongly recommended for both parties. They maintain builder cash flow and reduce customer risk. Payment on completion is fine for small, quick jobs but creates too much risk on larger projects.

What happens if a customer does not pay a stage payment?

Send a formal written reminder with a reasonable payment period (7-14 days). If still unpaid, you are within your rights to pause work -- this should be stated in your contract. Do not carry out further work while payments are outstanding. If the issue persists, pursue through mediation, solicitor's letter, or small claims court.
