how much deposit can a builder ask for

How Much Deposit Can a Tradesperson Legally Ask For?

Q: Is there a legal limit on deposits for building work?

No. No UK statute caps the deposit a tradesperson can request for building or trade work - it is whatever the two of you agree. However, consumer guidance consistently warns homeowners against paying more than around 25% upfront, so large deposits cost you jobs and invite suspicion. Keep deposits modest and justify anything higher in writing, usually by tying it to materials.

Q: Is a 50% deposit legal for a tradesperson?

Legally, yes - there is no statutory cap. Commercially, it is hard to justify unless the job involves bespoke or made-to-order items: custom windows, a made-to-measure staircase, a kitchen ordered to spec. In those cases, itemise what the deposit covers on the quote. For ordinary labour-led work, 10-25% is the widely accepted range and anything above it will make careful customers walk away.

Q: Why do customers prefer paying deposits by credit card?

Because of Section 75 of the Consumer Credit Act. Any purchase between £100 and £30,000 paid even partly by credit card makes the card company jointly liable if things go wrong, so the customer has a safety net beyond chasing you. Accepting card payments for deposits is therefore a genuine trust signal - it tells the customer you expect to deliver and are not hiding from accountability.

Q: Should I ever ask for full payment upfront?

No. Full payment upfront is the single biggest red flag consumer bodies warn homeowners about, and reputable trades never need it. If your worry is materials, take a deposit that covers them and stage the rest against visible milestones. A structure such as 25% on booking, 50% at first fix and 25% on completion protects your cash flow without asking the customer to carry all the risk.

There's no statutory cap on deposits for trade work in the UK - legally you can ask for whatever a customer will agree to. But consumer guidance, Trading Standards and every dispute resolution scheme sing the same tune: keep deposits modest, typically 10-25%, and be ready to justify anything above that. Ask for too much and you don't break the law - you break trust, lose jobs, and hand ammunition to any customer who later fancies a fight.

What the law actually says

No Act of Parliament sets a maximum deposit for building or trade work. What exists instead is guidance: consumer bodies tell homeowners to be wary of anything above 25% and to treat a demand for full payment upfront as the classic rogue-trader red flag. That guidance shapes what customers expect - which means it shapes what you can sensibly ask for, whatever the law technically allows.

When a bigger deposit is fair

A deposit above the usual range is defensible when your own money is committed before you start:

Made-to-order items - bespoke windows, staircases, kitchens cut to spec
Special-order materials the merchant will not take back
Long lead times where materials must be bought weeks ahead

The rule: if you ask for more than 25%, itemise what it covers on the quote itself. 'Deposit covers made-to-measure sash windows, ordered on booking, non-returnable' reads completely differently from a bare '40% upfront'.

The milestone structure that protects both sides

25% on booking + 50% at first fix + 25% on completion

Staged payments are best practice for anything beyond a day or two of work. The customer never pays far ahead of what they can see, and you're never owed more than one stage of work at any point. Tie each stage to something visible - first fix, plaster, handover - so nobody argues about whether it has been reached. Never, under any circumstances, ask for the whole job upfront.

Why card payments calm nervous customers

Here's an underused trust signal: anything costing £100 to £30,000 paid even partly on a credit card gets Section 75 protection - the card company becomes jointly liable with you. Customers who know this relax about deposits, because their money isn't riding solely on your reliability. Mentioning it when a customer hesitates over a deposit does more than any reassurance you could offer about yourself.

From the tools: A joiner my brother works with took a £6,200 bespoke oak staircase job and asked for 50% upfront without explaining why. The customer baulked and went elsewhere. On the next staircase, same money, he itemised it: 40% deposit 'to cover the oak, ordered and cut for your stair - non-returnable', balance on fitting. Signed the same evening. Nearly the same deposit, opposite result - because the customer could see exactly what their money was buying. He's used that wording on every made-to-measure job since, roughly a dozen now, and hasn't lost a single one over the deposit.

Quick answers

Is there a legal limit on deposits for building work?

There is no cap in law - the limit is commercial. Guidance steers homeowners towards 10-25%, so that is the range that wins work; go higher only where materials genuinely justify it, and say so on the quote.

Is a 50% deposit legal for a tradesperson?

It is legal, but only sensible for genuinely bespoke work where half the money is committed to materials before you start. Itemise it or expect the customer to walk.

Why do customers prefer paying deposits by credit card?

Card payments between £100 and £30,000 carry Section 75 protection, making the card issuer jointly responsible. That safety net makes handing over a deposit feel far less risky - so taking cards helps you win the job.

Should I ever ask for full payment upfront?

Never. It is the number-one warning sign homeowners are told to watch for. Cover your materials with a fair deposit, then stage the balance against milestones the customer can see with their own eyes.
