Taking Deposits and Stage Payments as a UK Trade Business — How to Protect Your Cash Flow in 2026

Why Take a Deposit

A deposit is not about being awkward or distrustful. It is standard commercial practice across the trades, and it does several jobs at once:

• It covers your upfront materials cost so you're not funding the job out of your own pocket. On a kitchen or bathroom, the suite, units, tiles and fittings can run to thousands before you've earned a penny in labour.
• It gives the customer skin in the game. A customer who has paid a deposit is committed. They're far less likely to cancel last minute, ghost you, or take your quote to a cheaper rival while you hold the date.
• It protects you against non-payment. If a job goes sour at the end, at least the deposit means you're not chasing the entire value of the work.
• It improves cash flow and reduces the working-capital gap. Money in before you spend it out is the difference between a healthy business and one that's always one slow-paying customer away from trouble.
• It weeds out tyre-kickers. Someone who balks at a reasonable, clearly-explained deposit is often someone who would have been a problem later.

How Much Deposit to Ask For

There's no single right figure, but there are solid rules of thumb. At an absolute minimum, your deposit should cover the materials you have to buy before you start. Beyond that:

• Small jobs (a day or two, low materials): often no deposit needed — just invoice on completion.
• Fit-out work (kitchens, bathrooms, joinery): commonly 25–50% up front, or the simple rule of “materials cost up front, labour on completion.”
• Large jobs (extensions, full renovations): a deposit on order plus a staged payment schedule (covered below) — never a single payment at the end.

Worked example — £8,000 bathroom. Say the suite, tiles, vanity unit, shower and sundry materials come to roughly £2,500–£3,000. A sensible deposit is exactly that: take £2,500–£3,000 on order to buy the materials, then the £5,000–£5,500 balance on completion. You've bought the bathroom with the customer's money, and your own cash is only ever exposed to your labour — which you can stop providing the moment something feels wrong.

Deposit vs Stage Payments vs Final Balance

These three terms get used loosely, so it's worth being clear:

• Deposit: a payment taken before work starts, usually to secure the booking and fund materials.
• Stage (or interim) payment: a payment made at agreed milestones as the work progresses, so your costs are reimbursed in step with the build rather than all at the end.
• Final balance: the remaining amount, due on completion once the work is signed off.

Small jobs use just a deposit and a final balance. Bigger jobs need stage payments in the middle — this is where most cash-flow damage is done if you get it wrong.

Stage Payments on Bigger Jobs

For builders, stage payments are the single most important cash-flow tool you have. On a job worth tens of thousands, you simply cannot afford to buy materials, pay subbies and labour, and wait until the end to be paid. Doing so is how profitable builders go bust — not because the job loses money, but because they run out of cash mid-build. This is called overtrading, and stage payments are the cure.

The principle is simple: tie each payment to a visible, completed milestone, so the customer can see what they're paying for and you never get more than one stage out of pocket.

Worked example — £40,000 single-storey extension. A clean payment schedule might look like this:

• Deposit on order: £4,000 (10%) — secures the booking and orders long-lead materials.
• Foundations and DPC complete: £8,000.
• Walls up and roof watertight: £10,000.
• First fix complete (plumbing, electrics, joinery carcassing): £8,000.
• Second fix and plastering complete: £6,000.
• Completion and snagging: £4,000 final balance.

Each payment is due within a short, agreed window (say 3–5 days) of the milestone being reached. That keeps your money roughly in step with your outgoings, stops you funding the build from your own reserves, and dramatically reduces overtrading risk. Put the full schedule in writing before a spade goes in the ground.

Retention

On larger or commercial jobs, the client may hold back a small percentage — typically 2.5–5% — as retention, releasing it once any snagging is signed off, often after a defects period. As a small trade firm you can use a gentler version of the same idea in your favour: structure the schedule so a meaningful final balance (say the last 10%) is only due once snags are done. That gives the customer confidence you'll come back to finish, and gives you a clear incentive to close the job out properly.

The Consumer-Law Angle

When your customer is a consumer (an ordinary homeowner, not a business), a few rules apply. This is general guidance — always put your terms in writing and take proper advice for your specific situation.

• Consumer Rights Act 2015: your terms must be fair. A deposit or cancellation charge that acts as a disproportionate penalty — rather than reflecting your genuine costs and losses — can be unenforceable. A non-refundable deposit can usually only retain what you've actually lost or spent, not an arbitrary figure.
• Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013: if the contract is agreed away from your business premises — for example, you quote and the customer signs up in their own home — the customer generally has a 14-day cancellation right (a cooling-off period).
• Starting within the cooling-off period: the customer can ask you to begin before the 14 days are up, but you should get their express written request and acknowledgement that they may be charged for work done if they later cancel. Without that, starting early — and keeping a deposit — can leave you exposed.

The safe approach is straightforward: put everything in writing, make your deposit and cancellation policy clear before any money changes hands, and get a signed agreement to start within the cooling-off period if you need to begin sooner.

How to Ask for a Deposit Without Losing the Job

Most trades who lose jobs over deposits lose them on framing, not on the figure. If you sound apologetic or uncertain, the customer senses it. If you treat the deposit as completely normal — because it is — they will too. The keys are:

• Make it standard. State it as routine policy, not a special request: “I take a 30% deposit to order your materials, then the balance on completion.”
• Put it in the written quote up front, so it's never a surprise when you ask. The deposit and payment schedule should be visible the moment they read your price.
• Explain what it covers. “The deposit goes straight on your suite and tiles so I can get them ordered and booked in.” People happily pay for something tangible.
• Be matter-of-fact, not apologetic. No “I'm really sorry but I'll have to ask for…” — just state it plainly.
• Make paying easy. Offer bank transfer or card so there's no friction.

Example wording on a quote: “A deposit of £2,750 is payable on acceptance to order materials and secure your start date. The balance of £5,250 is due on completion.”

Example wording in person: “Happy to get you booked in. The way I work is a deposit to cover the materials, then you settle the rest once you're happy it's all done. I'll email the details over.”

Taking Deposits Safely

Protect yourself and the customer with a clean paper trail:

• Take payment by bank transfer or card rather than cash — it's traceable and looks professional.
• Issue a receipt or invoice clearly marked “deposit,” showing the amount, the date, what it's for and the balance outstanding.
• Have written terms the customer has seen and agreed before they pay.
• Be explicit about what is and isn't refundable if they cancel, in line with the consumer rules above.

What to Put in Your Terms

A short, clear set of payment terms prevents most disputes. Cover:

• The deposit amount and that it's payable on acceptance.
• What the deposit covers (e.g. materials and securing the date).
• Your refund and cancellation policy, including any cooling-off arrangements.
• The payment schedule and milestones for stage payments on larger jobs.
• Late-payment terms — when payment is due and what happens if it isn't (you may be entitled to interest and reasonable recovery costs).
• When the final balance is due and how snagging is handled.

Red Flags: When a Customer Refuses a Reasonable Deposit

If a customer pushes back hard on a fair, clearly-explained deposit — one that just covers materials — treat it as a warning sign. Genuine customers understand that you can't order their kitchen on your own card and hope for the best. Resistance to a reasonable deposit often signals either a cash-flow problem on their side, an intention to haggle the final bill, or a customer who simply isn't serious. You're usually better off walking away than taking on the risk of funding the whole job yourself.
