You have found a builder you like, the quote looks fair, and they ask for the whole sum before they have lifted a tool. In 2026, with material prices still volatile and a steady run of “disappeared trader” stories in the local press, the temptation to just pay and get the job booked is real. Resist it. The single safest rule when you pay a tradesman upfront is that you never hand over the full amount before the work is done — you pay in stages tied to progress, with one narrow exception we will come to.
The short answer
Pay a deposit if you must, pay the balance in stages as work is completed, and never pay 100% before the job is finished. A reasonable deposit on a typical home job is small — often nothing for a day’s work, and rarely more than around 25% for a larger project where the trade has to order materials. Money you have already handed over is money you have no leverage over. A staged schedule keeps the trade motivated and keeps you protected if things go wrong.
Why paying in full upfront is the riskiest thing you can do
When you pay everything first, you have swapped places: the trade now holds your money and you hold a promise. If they vanish, run out of cash mid-job, or simply lose interest because a bigger contract came in, you are left chasing a refund you may never see. Established trades almost never ask for the full sum upfront, because they do not need to — they have working capital, trade accounts with merchants, and a reputation to protect. A demand for full payment before any work, especially in cash, is one of the loudest warning signs there is.
There is also a quieter risk. Even an honest trade who is paid in full has every incentive to prioritise the next customer who still owes them money. Your half-finished kitchen drops down the list. Staged payments are not about distrust; they are about keeping everyone’s interests pointing the same way.
What a fair payment schedule looks like
Every job is different, but the shape is usually the same: a modest deposit, one or more progress payments tied to clear milestones, and a final payment only once you have inspected the finished work.
The deposit
A deposit covers the trade’s upfront commitment — booking your slot, ordering materials, hiring plant. For a small job it is often unnecessary. For a kitchen or extension where thousands of pounds of materials are ordered in advance, a deposit of perhaps 10–25% is normal. Be wary of anyone wanting half the total before they start.
Stage or milestone payments
On larger projects the balance is split across the job: for example, a payment when the first fix is complete, another when plastering is done, and the final slice when everything is finished and snagged. Each payment should be tied to a visible, agreed milestone — not a date on the calendar, and not “when I ask”. If a trade wants to be paid ahead of the work, that is the conversation to have before you sign, not after.
The final payment and retention
Hold back the last payment until you have walked the job and listed any snags. On bigger contracts some homeowners keep a small retention — say 5% — for a few weeks after completion to cover defects that only show up once the heating runs or the first rain falls. Agree any retention in writing up front so it is not a surprise.
The one exception: genuine bespoke materials
There is a single situation where a larger upfront payment is reasonable: when the trade has to buy or commission something bespoke and non-returnable specifically for your job. Made-to-measure windows, a one-off run of kitchen units, engineered worktops cut to your template, or specialist tiles ordered from abroad all tie up real cash that the trade cannot recover if you pull out. In those cases it is fair to pay for those specific materials in advance — but pay the supplier or merchant directly where you can, ask for the order confirmation and invoice, and keep your labour payments staged as normal. Paying for the granite is not the same as paying for the whole job.
How to protect the money you do hand over
Here is the blunt truth: a payment you cannot trace is a payment you cannot recover. Pay by bank transfer or card, never large sums in cash, so there is a record of who got what and when. For anything over £100 and up to £30,000, paying at least part on a credit card can give you protection under Section 75 of the Consumer Credit Act, which makes the card provider jointly liable if the trade fails to deliver. Get the payment schedule and the scope of works in writing before any money moves, so there is no argument later about what each instalment was for. And check that whoever you are paying is the business named on the quote, not a personal account with a different name.
It is also worth checking who you are dealing with before the first payment. A trade registered with a recognised scheme such as TrustMark, or with the relevant body for their trade, has more to lose than a name on a leaflet.

What to do in the next 30 minutes
• Look back at your quote and check exactly when each payment falls due — and what it is tied to.
• If any instalment is due before matching work is done, draft a short email asking to move to a staged schedule.
• Confirm the bank or card details belong to the business named on the quote, not a personal account.
• Decide which payments you will put on a credit card for Section 75 protection on anything over £100.
• Check your trade is registered with a recognised scheme such as TrustMark or their trade body.
• Save the quote and agreed payment schedule to your free Home+ home logbook so they sit alongside your warranties and certificates.
When the payment schedule is staged and tied to real milestones, both sides know where they stand. Use Trade Pilot’s milestone-payment guidance to set out a fair, stage-by-stage schedule with the trades you are quoting — so the money follows the work, not the other way round.
Frequently asked questions
How much deposit is reasonable to pay a tradesman upfront?
For a small job, often none. For larger work where the trade orders materials in advance, a deposit of 10–25% is common. Be cautious about anyone asking for half or more before starting.
Is it ever normal to pay a tradesperson in full upfront?
Almost never for the whole job. The only fair exception is paying in advance for bespoke, non-returnable materials ordered specifically for you — and even then your labour payments should stay staged.
What if a trader insists on full payment in cash before starting?
Treat it as a red flag. Established trades have the cash flow and merchant accounts to start work on a deposit. A demand for full cash upfront leaves you with no record and no leverage.
Does paying by card actually protect me?
For purchases over £100 and up to £30,000, paying at least part on a credit card can make the card provider jointly liable under Section 75 of the Consumer Credit Act if the trade fails to deliver. Citizens Advice has clear guidance on how to claim.
What is a retention and should I use one?
A retention is a small percentage — often around 5% — held back for a few weeks after completion to cover defects. It is common on larger jobs. Agree it in writing before work starts so it is not disputed later.
