Builder Payment Schedules: UK Rights, Verified Stages, and a Template
A fair UK builder payment schedule uses a modest deposit usually within a reasonable range, short-interval stage payments tied to work you can actually verify on site, and a small retention held back until snagging is done. The Housing Grants, Construction and Regeneration Act 1996 sets the legal backdrop for most jobs, and the examples below show exactly how the numbers work in practice.
TL;DR:
For projects lasting more than 45 days, the Construction Act provides for stage or periodic payments unless both parties agree otherwise in writing.
Ask for invoices every 7 to 14 days, and require each payment trigger to name a visible, checkable result rather than a broad percentage.
Card payments may qualify for Section 75 protection on purchases from £100.01 to £30,000, making the provider jointly liable if the builder fails to deliver.
Keep 3% to 5% retention, with release tied in writing to practical completion and a defects window, commonly 28 to 30 days.
If bespoke materials justify a higher deposit, ask for the supplier invoice before agreeing to pay it, rather than relying on an unsupported figure.

Typical payment schedules and worked examples for small, medium and large jobs
The right schedule depends on how long the job runs and how much material has to be ordered upfront. A two-week bathroom refit doesn’t need the same structure as a four-month extension, but the underlying principle stays the same: you pay for what you can see has happened, not for a percentage someone estimates on a spreadsheet.
Here are three worked examples that reflect how builders and homeowners commonly structure payments:
Small job (garage conversion, around £14,000 to £18,000): 10% deposit on signing, 40% once walls, insulation and first fix are complete, 40% on second fix and finishing, 10% retention released after a two-week snagging period.
Medium job (single or double storey extension, roughly £45,000 to £85,000): 10% deposit, then four to six stage payments tied to groundworks, structural shell and roof watertight, first fix and plastering, second fix, and a final retention of around 5%.
Large job (loft conversion with structural work, from £35,000): 10% deposit, payments released at roof structure complete, windows and doors fitted, insulation and plasterboard, and final fix, with 5% retention held until practical completion.
When should the deposit move outside the usual range? If you agree to a different deposit, ask for the supplier invoice as evidence rather than simply taking the figure on trust. A lower deposit, or none at all, suits smaller jobs where materials are bought as the work progresses.
The FMB recommends short-interval invoicing, every 7 to 14 days, rather than waiting weeks between payments. This keeps both sides accountable and makes it far easier to spot a problem early, before a large sum has built up against incomplete work.
The language you use in the contract matters as much as the numbers. Write milestones as specific, checkable outcomes:
“Structural roof in place and weathertight” rather than “roof stage complete”.
“Windows fitted and external doors hung and locking” rather than “exterior finished”.
“First fix electrics and plumbing signed off by building control” rather than “first fix done”.
Specific milestones protect both parties. You know exactly what triggers a payment, and your builder knows exactly what they need to show to get paid.
Deposits, retentions and safe payment methods
A deposit exists to cover a builder’s initial costs, things like scaffolding hire, skip permits, and the first batch of materials. It should never cover profit upfront, and it should never be the bulk of the contract value paid before any work starts.
Typical deposit range: 5% to 15% of the total contract value for most residential jobs.
When a higher deposit is justified: bespoke joinery, structural steel, or any item ordered specifically for your project with a long lead time.
Retention: commonly 3% to 5%, sometimes quoted as 5%, held back from each stage payment or from the final instalment and released after a defects period.
One of the most reliable ways to protect a deposit is to pay by credit card where the amount allows it. Citizens Advice notes that Section 75 protection can apply to card payments for purchases between £100.01 and £30,000, which means your card provider can be jointly liable if the builder fails to deliver.
Retention is meant to give you leverage to get snagging fixed without withholding the entire final payment. The FMB’s payment protection checklist suggests tying retention release to practical completion plus a defects-cure window, commonly 28 to 30 days, which gives snagging time to surface without tying up funds indefinitely. Recent reforms affecting cash retention in construction are worth understanding before you agree terms, and our retention checklist walks through what’s changed and what to insist on.
Beyond cards, insured deposit schemes and escrow arrangements registered with the FCA add another layer of protection, particularly useful for larger deposits on bigger jobs. Whatever method you choose, avoid handing over large cash sums: there’s no paper trail, no card protection, and no way to dispute the transaction if something goes wrong.
The UK legal basics that affect payment schedules
You don’t need a law degree to understand the rules that shape a fair payment schedule, but a few points from the Construction Act are worth knowing before you sign anything.
Under the Housing Grants, Construction and Regeneration Act 1996, you’re entitled to stage or periodic payments on any construction contract expected to last longer than 45 days, unless you and your builder agree otherwise in writing. If your contract is silent on payment terms, the Scheme for Construction Contracts fills the gap automatically.
The Act also sets out how payment notices and final dates for payment work:
A payment notice must state how much is due and how that figure was calculated.
There’s a fixed final date for payment, agreed in the contract or set by the Scheme if the contract doesn’t specify one.
Withholding money lawfully requires a valid notice of intention to withhold payment, issued within the time limits the Act sets out: a builder (or you) can’t simply decide not to pay without following this process.
If a payment notice is wrong, late, or missing entirely, you don’t have to accept it at face value. The Act gives both parties the right to challenge figures through adjudication, a quicker and cheaper route than court.
If a notice looks incorrect, raise it in writing immediately and ask for the calculation behind the figure. If payment is genuinely late and no valid notice to withhold has been served, the Act also gives the party owed money the right to suspend performance until payment is made. For homeowners, the practical takeaway is simpler: keep every notice, invoice and written exchange, because they form the evidence trail if a dispute ever needs resolving formally.
Practical checklist to reduce payment disputes and keep the project on track
Most payment disputes start with ambiguity, not dishonesty. A clear contract and good record-keeping prevent the majority of disagreements before they start.
Insist your contract specifies scope of works, payment stages and dates, how variations are priced and approved, the defects process, and a dispute resolution clause.
Photograph progress at each stage, before covering up any work like insulation or first-fix wiring, so you have evidence of what was actually done.
Get every variation, from an extra socket to a change in materials, confirmed in writing with its cost before the work happens.
Keep a simple log of calls, site visits and decisions, even a few lines in a notebook or phone app is enough to settle a disagreement later.
If a payment is overdue on your side, don’t let it drift: explain the reason and agree a new date rather than going silent.
Pro Tip: Ask for a written sign-off at each milestone, even a short email confirming “stage complete, payment due” protects both sides and takes seconds to send.
If your builder’s payment is late and you believe it’s justified, chase it immediately and explain clearly what’s outstanding. If a builder asks for money you don’t think is due, you can withhold proportionately rather than paying the full stage, provided you’ve issued a valid notice explaining why. For disputes that won’t resolve through conversation, Citizens Advice is a sensible first stop, and adjudication remains available under the Construction Act if the sums involved justify it.
Sample payment schedule template and how to adapt it for your job
A written schedule doesn’t need to be complicated, but it does need to cover the same fields every time so nothing gets left to interpretation.
Total contract price and currency.
Deposit amount and date due.
Each stage payment: amount, percentage, and the specific milestone that triggers it.
Retention percentage and the date or condition for release.
Agreed payment method and number of days to pay an invoice once issued.
For shorter jobs, collapse this into two or three stages instead of five. Whatever the length, every milestone should describe something you can see and photograph, never a percentage estimate. Sign and date the schedule alongside the main contract, and keep copies, paper and digital, somewhere you can find them quickly if a dispute arises. Readers who want another template to compare against can see the version at House A-Z’s construction payment schedule guide.
How EvoStruct applies these principles: transparent quotes, milestone invoicing and virtual tours
We build our own process around the same principles this guide sets out. Detailed quotes arrive within 24 hours of enquiry, which means a payment schedule gets drawn up against real costs rather than rough guesswork, as we explain in our piece on quotes versus estimates.
Milestone invoicing tied to verifiable stages, not vague percentages of “work done”.
Live virtual tours of active projects, so you can see workmanship and progress before committing to a contract.
Clear retention terms agreed upfront, with release tied to practical completion and snagging.
This approach gives you the evidence trail a fair schedule depends on: photographs, sign-offs and a quote you can check against the invoice at every stage, exactly what the FMB and Citizens Advice both recommend homeowners insist on.
How to read and understand a builder payment schedule within a construction contract
A payment schedule should sit inside your main contract, not as a separate, looser document. When you read one, check three things first: the total figure matches the quote, each stage payment adds up to that total alongside the deposit and retention, and every milestone is described as a physical outcome rather than a percentage.
Look closely at the trigger for each payment. “Plastering complete” is checkable. If a schedule uses percentage language anywhere, ask your builder to rewrite it around specific deliverables before you sign.
Check the payment method and timeframe too. A schedule should state how many days you have to pay once an invoice is issued, typically 7 to 14 days, and what happens if a payment is delayed on either side. Finally, confirm the retention line: the percentage, and the condition that releases it, should be spelled out rather than left as a verbal understanding. If any of these fields are missing, treat that as a prompt to go back to your builder before work starts, not something to sort out once the job is underway.
How payment schedules tie into the wider contract terms and variations
A payment schedule only works if it’s read alongside the rest of the contract, particularly the clauses covering variations, defects and scope. If the scope of works is vague, the payment stages built on top of it will be vague too, which is where most disputes begin.
Variations, any change to the original specification, should always be priced and agreed in writing before the work happens, with the cost added to (or deducted from) the relevant stage payment. A contract that allows verbal variations invites disagreement about what was actually agreed and what it should cost.
The defects clause matters just as much. It should state how long you have to report snagging after completion and tie that period directly to the retention release date, so there’s no ambiguity about when the final payment is genuinely due. If you’re planning an extension that involves a shared wall or boundary, our party wall agreement playbook explains how those approvals can affect timing, and in turn, when certain payment stages become due.
Common clauses affecting payment schedules and how they impact clients
A handful of clauses show up repeatedly in UK building contracts, and each one directly shapes how and when you pay.
Pay-when-paid clauses: largely unenforceable under the Construction Act for most contracts, so a builder generally can’t delay paying a subcontractor, or ask you to delay a payment, simply because a third party hasn’t paid them.
Liquidated damages clauses: set a pre-agreed daily or weekly sum deducted from payments if the project overruns, useful for keeping a schedule on track but only fair if the figure is realistic.
Set-off clauses: allow you to deduct a reasonable sum from a payment to cover defective work, provided you’ve issued the correct notice.
Force majeure clauses: cover delays from circumstances outside anyone’s control, such as extreme weather, and should state how payment dates shift as a result.
Reading these clauses before you sign, rather than after a dispute starts, is what turns a payment schedule from a wish list into something you can actually rely on.
Examples of payment schedules specific to different types of projects
A loft conversion and a commercial fit-out both use staged payments, but the stages themselves look very different because the work itself is different.
For a loft conversion, stages typically follow the physical build sequence: deposit, roof structure and steelwork, windows and insulation, first fix, then second fix and decoration, with retention released after snagging. Because loft work is structural and sequential, each stage is easy to verify by eye.
A commercial fit-out or refurbishment often runs on a longer, more granular schedule, with payments linked to specific trades finishing (mechanical and electrical first fix, partitioning, flooring, final commissioning) rather than broad building stages. Retention on commercial jobs can also be split, with a portion released at practical completion and the remainder at the end of a longer defects liability period, sometimes six to twelve months, reflecting the complexity of the installed systems.
Garden rooms and garage conversions sit closer to the loft conversion model: shorter programmes, fewer stages, and a defects period measured in weeks rather than months. Matching the schedule’s structure to the project type, rather than using one generic template for every job, is what keeps payments proportionate to progress.
A homeowner’s guide to negotiating payment terms
Most builders expect some negotiation on payment terms, and a polite, specific request rarely causes friction.
Pause payment, not the relationship, if a milestone genuinely isn’t met: explain exactly what’s missing and when you’ll release funds once it’s fixed. If that doesn’t resolve things, escalate calmly through the contract’s dispute clause before anything turns adversarial. Our sample schedule and residential services team are there if you want a second opinion on terms before signing.

FAQ
How much does a builder get paid in the UK?
Builder pay varies widely by trade, region and project size, and there’s no single published UK-wide day rate that applies to every job. What matters for your payment schedule is agreeing a fixed total contract price upfront, then releasing it in verifiable stages rather than focusing on what an individual tradesperson earns.
When should I pay a builder?
The FMB recommends short-interval invoicing, every 7 to 14 days, so neither side carries a large unpaid balance for long.
How much should I pay a builder per day?
There’s no standard day rate figure for UK building work, since it depends heavily on trade, location and project complexity. A fixed-price schedule with stage payments tied to milestones avoids this question altogether and gives you a clearer, more predictable way to budget.
Can you pay builders in instalments?
Yes, and for any job expected to run longer than 45 days, the Construction Act actually entitles you to pay in stage or periodic instalments rather than one lump sum. Instalments should be tied to specific, verifiable milestones and set out clearly in your written contract.
