When a Deposit Is Reasonable and How Much to Ask For

Why deposits exist

A deposit isn't about distrust — it's about cash flow and risk management. In building work you routinely have to buy materials before you start, book specialist labour weeks ahead, and block a slot in your diary. Without a deposit you have no protection when a customer backs out at the last minute. I've lost money on bespoke kitchens and made-to-order windows because a client cancelled after suppliers had been paid. A deposit turns those uncertain promises into a real commitment and protects your business from becoming an unpaid supplier.

Think of a deposit as a performance filter. If someone won't put a modest sum down, they're more likely to haggle, delay decisions or avoid paying at the end. In my time running a company, the customers who baulked at a reasonable deposit were regularly the ones who caused the most administrational hassle and late payments later on. Taking a deposit weeds out the highest-risk jobs early, saving you time and stress so you can focus on customers who value and respect your trade skills.

A deposit also covers your exposure on materials and subcontractors. Suppliers often want payment or a non-refundable deposit to confirm orders for bespoke items — worktops, made-to-measure doors, or laminate windows. If you don’t secure funds up front, you either pay out of your own pocket or risk the supplier charging cancellation fees. That’s not just numbers on a spreadsheet; it’s real money that affects your ability to pay the lads and buy the next van load of materials. Deposits keep the business moving without gambling on trust.

Finally, deposits buy you planning certainty. When you take money for a job you can schedule labour and deliveries with confidence because the client has skin in the game. That means fewer last-minute rearrangements, fewer gaps in your diary and a more professional service. Customers who pay early are more likely to communicate properly and make decisions promptly. That alone improves profitability — time saved on chasing equals more billable time. Treat deposits as a basic business tool: they protect cash flow, reduce risk and improve project delivery.

How much to ask for

There’s no one-size-fits-all number, but simple rules will keep things fair and defensible. For small day jobs — a one- or two-day bathroom repair, replacing a couple of doors, fitting a radiator — 25–33% of the total price is standard. That covers the initial materials and compensates you for blocking your diary. Customers expect this. Ask less and you take on unnecessary risk. Ask more, and you’ll scare some sensible people off. Keep the figure straightforward: a third for small jobs is easy to explain and hard to argue with.

For larger installs where you must outlay several thousand pounds on materials or place non-refundable orders with suppliers — kitchens, bathrooms, windows, staircases — the deposit should match what you’ll actually pay before work starts. If your supplier asks for a 50% non-refundable deposit, your customer should pay that plus a small buffer for delivery and storage. Tell them the deposit pays for their specific items. Making the deposit equal to your real exposure avoids accusations of profiteering while keeping your business safe.

Bespoke and made-to-order items need special handling. Suppliers often require non-refundable deposits to cut glass, machine timber or book specialist edge-work. If an item is bespoke, make the customer sign that all order costs are non-refundable. A sensible deposit is the supplier’s deposit plus a modest margin to cover your admin and storage risks. For example, if bespoke doors cost £2,400 and the supplier wants £1,200 up front, asking for £1,300–£1,400 from the client is reasonable and clearly tied to real costs.

Don’t forget staged payments. For long jobs spread over weeks or months, structure payments into clear stages like deposit, start on site, mid-point, and completion. That keeps your cash flow steady and spreads the financial burden for the customer. Each stage should be tied to a tangible event: materials delivered, plastering complete, cabinets fitted. Say you’re doing a £12,000 kitchen: deposit £3,000 to secure, £4,000 on delivery, £3,000 on fit, £2,000 on completion. Clear stages reduce disputes and make chasing money easier.

Putting it in writing

Never rely on a handshake when money is involved. All deposit terms must be on paper — in your quote, your email or a short contract. Itemise the deposit amount, why you’re taking it, when it’s due and the payment method. Say plainly whether the deposit is refundable, partially refundable, or non-refundable and under what circumstances. Clear wording avoids the ‘he said, she said’ later. Keep the language simple: customers don’t need legalese, they need to understand what they’re committing to. That clarity keeps the job moving and keeps you protected.

Include cancellation and change-of-mind terms. Spell out scenarios like supplier lead times, bespoke items and booking cancellations. For example: ‘Deposit pays for bespoke worktop order and is non-refundable once supplier has manufactured it.’ If a client cancels before you order, make it clear whether you’ll refund the deposit in full or minus admin charges. Be sensible but firm — you’re not running a charity. Transparently written terms reduce awkward conversations and make your decision to keep part or all of a deposit defensible.

Use receipts and confirmations as standard practice. When you receive a deposit, send a confirmation email or a signed receipt that reiterates the terms: amount, what it covers, and next steps. Bank transfers are best because they leave a trace; card payments are fine but factor in fees and authorisation times. If a client pays cash, still provide a paper receipt and log it in your accounts. Regular, clear documentation protects both sides and makes chasing or defending payment straightforward if things go sideways.

Make your deposit terms part of the sales process, not an afterthought. Train anyone who quotes or takes payments to explain why the deposit is needed and what it covers. A brief line in the quote like ‘Deposit required to secure works and order materials: £X (non-refundable once orders placed)’ removes ambiguity. Clients are more likely to accept a deposit if it's explained as a normal business practice rather than an arbitrary demand. Keep it professional and matter-of-fact; tradespeople respect clarity and customers respect honesty.

Handling deposit disputes

Disputes happen, but how you handle them separates a rough builder from a professional one. First, stay calm and refer to the written terms. If your paperwork clearly states the deposit is partial or non-refundable in certain scenarios, point to that documentation. Explain the supplier costs, the labour you’ve turned down and any storage or admin expenses. Customers often accept a reasonable explanation when they see the arithmetic. Presenting facts professionally avoids escalation and keeps dialogue constructive rather than emotional.

If a customer claims the deposit is unfair, offer a breakdown. Show invoices or supplier confirmation if needed: copy of the kitchen order, delivery charges, or specialist joiner’s booking. Transparency kills suspicion. If you really are at fault — you made a mistake with dates or specifications — admit it and negotiate a fair remedy. Often that means refunding part of the deposit and offering a discount on the next stage. Being honest and solution-focused keeps your reputation intact and reduces the chance of a complaint to trading standards or a bad online review.

Use mediation before litigation. Most disputes are better solved with a sensible middle ground: partial refund, reschedule, or altered scope. If the customer refuses, document all communications and escalate to a formal letter outlining why the deposit is retained per the contract. Small claims should be a last resort — they cost time and money. If the potential return is small and the customer is stubborn, weigh the costs of pursuing it. Sometimes walking away is cheaper than chasing twenty hours of admin for a £200 deposit.

Protect yourself going forward by tightening your terms after every dispute. Update your standard quote to make any grey areas impossible to misinterpret. If a particular supplier demands non-refundable deposits, put a clause in every estimate explaining that bespoke orders and supplier deposits are non-refundable once placed. Experience changes how you run the job — use disputes as a learning tool. The next time a similar situation arises, you’ll have clearer wording and fewer sleepless nights defending a decision you can justify with paperwork.

Taking and tracking payments

How you take payments matters as much as how much you ask for. Bank transfers are the simplest and cheapest: faster clearing, minimal fees and a clear paper trail. Take card payments if customers prefer — but account for processing fees when you price the job. Don’t accept cheques unless you’re prepared to wait for them to clear; that’s a risk you don’t need. Use a business bank account and a simple payment log that records date, amount, payer name, invoice number and clearing status. Accurate records make month-end and VAT time far less painful.

Use invoicing software or even a simple spreadsheet to match deposits to quotes and job numbers. When a deposit comes in, mark it against the job and issue a receipt that repeats the deposit terms and next payment dates. That prevents mistakes like applying a deposit to the wrong job or losing track of balances. If you run a small team, share visibility — your office person or estimator should always know what’s been received. Good housekeeping makes cash flow predictable and reduces arguments about whether a deposit was taken.

Don’t forget VAT and accounting treatment. Deposits are usually treated as income when received, so log them correctly. Speak to your accountant about timing and VAT treatment if you’re unsure — getting this wrong can cause headaches at tax time. Also consider simple payment reminders: a polite email two weeks before the next stage payment due, and a firm but fair text or call three days before. Most clients pay quickly if you make it easy and remind them without being aggressive.

Practical examples and scripts

Keep your explanations short and practical when asking for a deposit. For a kitchen fit, you can say: ‘We'll need a deposit of £2,500 to order the cabinets and worktop. The supplier requires this to start manufacture and it's non-refundable once ordered. We'll confirm delivery dates and the next stage payment before installation.’ That’s clear, tied to supplier obligations, and sets expectations. Don’t bury the important parts in long paragraphs — customers are more likely to agree if they’re presented clearly and honestly.

For a small job script: ‘I can book you in for next Tuesday. To secure the day I ask for a £100 deposit which offsets the materials and guarantees the slot. If you cancel more than 48 hours before, I’ll refund it; within 48 hours I keep the deposit to cover the lost slot.’ Short, direct and fair. Having a few set scripts like this for common scenarios saves time, reduces miscommunication and makes you look organised. Your team should use the same scripts to keep messaging consistent.

Use simple written templates too. A short deposit clause in your quote might read: ‘Deposit: £X required to place orders or secure start date. Non-refundable once bespoke items ordered or supplier deposits paid. Balance due on completion or as per staged payment schedule.’ Keep a folder of supplier deposit confirmations to attach to quotes when needed. When disputes arise, having a clear paper trail and matching supplier paperwork makes it obvious why you kept a deposit and prevents most arguments from starting in the first place.

Common mistakes

• –Asking for 50%+ deposits with no material justification, which makes customers suspicious
• –Taking cash deposits with no receipt or record
• –Not stating in writing whether the deposit is refundable
• –Using deposit money from one job to fund materials for a different job, leaving no buffer if either job changes

Questions people ask

Can a customer legally ask for their deposit back?

It depends on your written terms and the reason for cancellation. If materials have already been bought specifically for the job, it's reasonable to retain that portion. For contested cases, take legal advice on the specific circumstances.

Should I take deposits on every job?

Not necessarily on very small, quick jobs where you supply nothing up front — but on anything involving material spend or a booked slot, a deposit protects your cash flow.
