Deposits and stage payments on domestic building work: how to structure them

On domestic building work, how you structure payments matters as much as how much you charge. Get it right and cash flow largely looks after itself. Get it wrong and you end up funding the client's project out of your own pocket — buying materials and paying wages weeks before the money to cover them arrives. That gap is where otherwise healthy firms get into trouble.

Here is a sensible way to structure deposits and stage payments on domestic jobs.

The deposit: proportionate, not punitive

A deposit does two things: it confirms the client is committed, and it funds the initial materials so you are not out of pocket from day one. Keep it proportionate. A modest deposit against confirmed material orders is reasonable and normal. An excessive up-front demand frightens good clients and can fall foul of consumer protection rules, which look unfavourably on large payments taken far ahead of work. As a rule of thumb, the deposit should cover what you genuinely need to commit before starting, not sit as a large cushion in your account.

Stage payments: tie them to milestones, not dates

The biggest single improvement most builders can make is to bill against verifiable milestones rather than the calendar. "On completion of first fix" is something both parties can look at and agree has happened. "Week four" is not, because weeks slip, and a date-based schedule invites an argument every time the programme moves. Milestones remove that friction because the trigger is visible.

Keep the stages small

Frequent, smaller invoices beat a few large ones for two reasons. They smooth your cash flow, so you are never far ahead of your costs. And they shrink the size of any single dispute — a client querying a £3,000 stage payment is a much smaller problem than one querying a £30,000 final bill. Small and often keeps everyone calmer.

Put the schedule in writing before you start

On domestic jobs this matters more than most builders realise. The statutory payment protections in the Construction Act specifically exclude work for a "residential occupier" — a homeowner having work done on their own home. So on a typical domestic job, your right to be paid, and when, comes almost entirely from the contract you agreed, not from statute. A clear, written payment schedule the client has seen and accepted is therefore your main protection, not a formality. (We go deeper on the legal side in getting paid on time.)

Retention: usually not worth it on domestic work

On larger and commercial jobs, clients sometimes hold a small percentage of each payment as "retention," released after a defects period. It is far less common on domestic work, and usually not worth introducing — it parks your money and a meaningful share of retained sums are never released without chasing. If a domestic client asks for it, make sure the release terms and date are written down and diarised.

Make the money visible as you go

Clients pay faster when they can see what they are paying for. An invoice that lands cold, with a number the client cannot reconcile, gets queried. An invoice that arrives against a backdrop of visible progress and agreed costs gets paid, because it is the expected conclusion of a story the client already believes.

This is why Builders Ready keeps a live finance summary — quoted, invoiced, paid, outstanding — visible to both you and the client, with invoices tied to the project they have been watching. But the structure comes first: proportionate deposit, small milestone-based stages, and a written schedule agreed before a brick is laid. Get that right and you stop being your client's bank.
