Deposits and Contracts: What's Normal for Renovation Work

Deposits and payment structure are one of the areas where homeowners are least sure what's actually normal — which makes it easy to either overpay upfront unnecessarily, or unfairly suspect a legitimate, standard request. Here's what genuinely reasonable practice looks like.

What a reasonable deposit covers

A sensible deposit covers materials ordering and the initial setup cost of starting the project — not the bulk of the total project value. The exact proportion varies with project size and how much needs to be ordered upfront (bespoke joinery or made-to-order kitchen units, for example, genuinely need paying for before they're made), but it should always be tied to something real, not just "start work."

Staged payments through the project

For anything beyond a small job, payment in stages tied to genuine progress — rather than a single lump sum, in either direction — protects both parties. Neither side is left overexposed if something goes wrong partway through.

What a proper written agreement should include

• A clear scope of work — what's included, and just as importantly, what isn't
• The total price, and whether VAT is included
• The payment schedule and what triggers each stage
• An estimated timeline
• How variations to the scope will be priced and approved
• What guarantee applies once work is complete

What's not normal

• A deposit that's the majority of the total cost, requested before any real scope has been agreed in writing
• Being asked to pay the final amount before work is actually complete and inspected
• No written record of price or scope at all — verbal-only agreements
• Pressure to pay in cash with no invoice or receipt

A worked example: a typical staged payment structure

For a mid-sized project like a full bathroom or kitchen renovation, a genuinely typical staged structure looks something like this — every contractor structures it slightly differently, but the shape is a useful benchmark:

• Deposit on agreement (roughly 10-20%): covers materials ordering and initial setup.
• Stage payment at first-fix complete (roughly 30-40%): once plumbing/electrics first-fix and any structural work is done and visible.
• Stage payment at second-fix/finishing (roughly 30-40%): once units, tiling, or fixtures are installed and the space is largely complete.
• Final payment on completion (remaining balance): after a walk-through confirms the work is finished and satisfactory — this should never be paid before that walk-through happens.

The exact percentages vary by project and contractor, but the principle holds: each payment should follow a visible, checkable stage of progress, not a calendar date or a verbal assurance that work is "nearly done."

What to do if a payment request feels off

Ask directly what stage of work the payment corresponds to, and don't feel pressured to pay ahead of that stage being genuinely complete. A legitimate contractor working to a staged schedule will have no issue confirming exactly what's been finished before asking for the next payment.

See our full guide on red flags when hiring a builder for how a payment request fits into the wider picture of choosing who to work with, and what to ask before you hire a contractor for the questions that should surface this upfront, before you're already committed.

Is there a deposit protection scheme?

Unlike a tenancy deposit, there's no single statutory deposit protection scheme for renovation work in the UK. Some protection does exist in practice: paying a deposit by credit card can trigger Section 75 protection for amounts within its scope, and some trade bodies and insurance-backed guarantee schemes offer a degree of cover for members' customers — worth asking a contractor directly whether they're a member of one, and checking what it actually covers, rather than assuming any particular scheme applies.

If a contractor asks for more than expected mid-project

A genuine variation — something unexpected found once work starts — is normal and should be priced and agreed before the extra work happens, not billed after the fact as a surprise. A request for a significant additional payment with no clear explanation of what it's for, particularly if it doesn't correspond to a visible stage of progress, is worth pausing on and asking directly what it covers before paying it.

Keeping your own record

Beyond whatever the contractor provides, it is worth keeping your own simple record as the project goes: dates and amounts paid, what stage each payment corresponded to, and copies of any written confirmation. This takes a few minutes per payment and matters far more if a disagreement ever arises than trying to reconstruct the payment history from memory or bank statements alone months later.
