How to Take a Deposit Before a Job (UK Trades)

To take a deposit before a job, set one clear written deposit rule (a fixed sum or a percentage), state it on your quote before the customer agrees, and collect it through a payment link or your bank details at the point of booking. Keep the amount proportionate to your real costs (your time, materials and a reserved slot) so it stays fair and enforceable under UK consumer law. That's the whole thing. The rest of this post is how to do each step without sounding like you don't trust people, and without tripping over the Consumer Rights Act.

I'm a sole trader in Torbay and I've watched too many days get torn in half by a no-show. A deposit is the single cheapest fix for that. Here's how to start.

The 5-step deposit checklist

1. Decide your rule once. A fixed booking fee for small jobs, a percentage for larger ones. Write it down so every quote uses the same number.
2. Put it on the quote, in writing, before they say yes. The customer must see and agree to the deposit before the contract is formed.
3. Tie the amount to real cost. Time held, materials ordered, the slot you turned others away for. Not a random round number that looks like a fine.
4. Collect at the booking moment. A payment link or your bank details the second they confirm. Job isn't in the diary until it lands.
5. Set out refunds and cancellation in plain words. What's refundable, what isn't, and why. No surprises later.

Do those five and you're taking deposits properly. Now the detail.

Why take a deposit at all?

Because a deposit turns a vague "yeah, book me in" into a real commitment, and it stops you eating the cost when someone vanishes. A confirmed booking with money behind it is worth ten "definite maybes."

Three things a deposit protects:

• No-shows and wasted callouts. If you drive 40 minutes to an empty house, that's fuel, time and a slot you could've sold. Money up front makes people show up, or tell you early so you can refill the slot.
• Materials you've already bought. Order a specific part or a bathroom suite for one customer and you're exposed if they walk. A deposit covers what you've laid out.
• Your diary. When you hold a morning for someone, you turn other work away. The deposit is the price of reserving that time, the same way a restaurant holds a table.

Service businesses across other sectors report that even a small deposit sharply reduces no-shows. I won't quote a hard percentage for trades specifically because the headline figures floating around come from salons and clinics, not from us. But the direction of travel is obvious, and it matches what I see: ask for skin in the game and the flaky bookings filter themselves out before they cost you a day.

How much deposit should a tradesperson charge?

Match the deposit to the job: a modest fixed fee for small work, a percentage (commonly 10-25%) for bigger jobs where you're committing materials or several days. The number should cover your real exposure if they cancel, no more.

A simple way to think about it:

• Small jobs and callouts (a tap, a fault-find, a quick repair): a flat booking fee works best. It's enough to make people serious without feeling heavy. If you already charge a callout, your deposit and your callout fee can be the same thing. I dug into when that makes sense in whether to charge a call-out fee on small jobs.
• Medium jobs (a day or two, some materials): a percentage of the quote, often 10-20%, taken on booking.
• Big jobs (full installs, multi-day, expensive materials ordered in): a larger deposit or staged payments. A deposit to book, a materials payment when you order, the balance on completion. That way you're never far out of pocket.

The test for the amount is simple: if they cancelled tomorrow, what have I actually lost? Price the deposit to that. A deposit that's wildly more than your real cost isn't a deposit, it's a penalty, and the law treats those two very differently. More on that next.

Is it legal, and can I keep it if they cancel?

Yes, deposits are completely legal, and you can keep a fair one to cover genuine costs. What you cannot do is keep an amount that's really a penalty. UK consumer law lets you recover what cancelling actually cost you. It does not let you punish the customer for changing their mind.

The relevant rules are in the Consumer Rights Act 2015. Its list of terms that may be unfair specifically flags terms that make a consumer pay a "disproportionately high sum" when they cancel. In plain English: a deposit that reflects your lost time and materials is fine; a deposit that's miles above your real loss can be challenged as unfair and unenforceable.

Two more things worth knowing, both from Citizens Advice's guidance on cancelling a service you've arranged:

• The 14-day cooling-off period. If a consumer books a service off-premises or at a distance (over the phone, by text, online, at their door) they usually get 14 days to cancel and get money back. The exception: if they asked you to start work inside that period, you can keep what covers the work done so far. For most quote-then-book jobs, get the customer to agree in writing that work can begin, and keep clear records.
• A clear cancellation clause matters. Once you're past cooling-off, what you can keep depends heavily on what you wrote down and what they agreed to. A fair, plainly-worded deposit-and-cancellation term is your best protection. A vague one is a fight waiting to happen.

I'm a tradesman, not a solicitor, so treat this as the lay of the land rather than legal advice. But the principle is easy to live by: charge to cover your costs, write it clearly, and you're on solid ground.

How do I ask for a deposit without losing the customer?

State it as a normal, matter-of-fact part of how you book, not as a favour you're asking for. Confidence does most of the work. When a deposit is just "how it works here," nearly everyone pays it. When you sound apologetic, you invite a negotiation.

Three scripts you can lift:

On the quote (written):

"To book your slot I take a deposit of £X (or X% of the total). This holds your date and covers materials. It comes off your final bill. The balance is due on completion."

By text, confirming a booking:

"Happy to book you in for Tuesday AM. I'll send a payment link for the £X deposit to hold the slot, then you're all set. Anything you need before then, just ask."

On the phone, if they hesitate:

"Totally normal question. The deposit just reserves your time and covers any parts I order in. It all comes off the final price, and your slot's locked the moment it's paid."

Notice what every version does: explains why (holds the slot, covers materials), confirms it comes off the final bill, and stays relaxed. The customers who balk at a fair, transparent deposit are very often the same ones who'd have ghosted you anyway. Letting them filter themselves out is a feature, not a loss.

How do I actually collect the deposit?

Take it at the booking moment, while the customer is keen. The longer the gap between "yes" and "paid," the more bookings leak away. The job goes in the diary when the deposit lands, not before.

You've got three practical ways:

• A payment link. Send a link by text or email, they tap and pay by card. Cleanest option, and it timestamps the booking. This is where a system that lets you send a link the instant you confirm earns its keep.
• Bank transfer. Give your details, ask them to reference their name and date. Free, but slower and easier to "forget."
• Card on the spot. Fine if you're stood in front of them, less use for phone and online bookings.

For phone, text and web enquiries, a payment link wins because it closes the gap. The customer who said yes thirty seconds ago is the most likely to pay. The one you're chasing two days later is already cooling off. This is exactly the problem OptitechAutomation lets you take deposits and get paid up front solves: one booking, link sent, money in, slot confirmed, all in the same minute. If you want the bookings-with-deposits side running quickly, you can set up deposit-ready bookings in minutes.

I'll keep this benefit-level on purpose. The point isn't the plumbing, it's that the deposit gets collected before the customer's enthusiasm fades, instead of becoming another debt you have to chase. Chasing money after the job is a separate headache, and I wrote up how to stop that in how to get invoices paid on time.

How do I write my deposit terms?

Keep it short, specific and fair. Say the amount, what it covers, that it comes off the final bill, and what happens if they cancel. Plain words beat legal-sounding waffle, and they hold up better too.

Here's a clause you can copy and adapt:

Deposit and cancellation
A deposit of [£X / X% of the quoted total] is payable to confirm your booking. Your date is reserved once the deposit is received. The deposit covers reserving your time slot and any materials ordered for your job, and is deducted from your final invoice.

If you cancel more than [48 hours / 7 days] before the agreed start, your deposit is refundable, less any non-returnable materials already ordered for your job. If you cancel with less notice, we may retain an amount covering the time reserved and any materials and costs already incurred.

If you booked this service remotely (by phone, message or online), you have a 14-day right to cancel, unless you have asked us to begin work within that period, in which case we may charge for work already done.

The balance is due on completion.

Adjust the notice window and amount to your trade. The non-negotiables: the figure is tied to real cost, the refund position is spelled out, and there are no nasty surprises. That's what keeps it fair under the Consumer Rights Act and what keeps it out of a dispute.

FAQ

Do I have to refund a deposit if the customer cancels?
It depends on when and what your terms say. Inside the 14-day cooling-off period (for remote and doorstep bookings) you generally refund, minus any work you've already done at their request. Outside it, you can keep an amount that covers your genuine costs, time held and non-returnable materials, as long as your written terms set that out and the sum is proportionate, not a penalty.

Does the deposit come off the final bill?
It should, and you should say so plainly. A deposit that's deducted from the total feels fair to customers and removes the "am I paying twice?" worry. It's a part-payment that secures the booking, not an extra charge.

What if the customer disputes the deposit or the deduction?
Try to settle it directly first. Point to the written term they agreed to and your actual costs. If you can't agree, Citizens Advice suggests an alternative dispute resolution (ADR) scheme as a route that avoids court. This is exactly why a clear, fair, written clause matters: it's your evidence.

Are deposits worth it on small jobs?
Often yes, as a flat booking fee rather than a percentage. Even a small amount filters out time-wasters and stops you driving to empty houses. If you already charge a callout, fold the two together so the customer pays once.

Is a deposit taxable income?
Money you receive is part of your turnover, so yes, deposits count toward your income for tax. If a deposit is refunded, you account for that too. I'm not an accountant, so check the specifics with yours, but don't treat deposits as invisible money.

Key takeaways

• A deposit is the cheapest fix for no-shows and wasted callouts. Set one rule and use it on every quote.
• Tie the amount to your real cost: time reserved plus materials. A fair deposit is legal; a penalty is not.
• Put the deposit on the quote in writing before the customer agrees, so it's part of the deal, not a surprise.
• Collect it at the booking moment with a payment link. The gap between "yes" and "paid" is where bookings leak.
• Write a short, plain deposit-and-cancellation clause covering refunds and the 14-day cooling-off right.
• Ask for it confidently as "how I book." The people who balk at a fair deposit are usually the ones who'd have ghosted you anyway.
