Stage payments for building work: how to set them up

Last reviewed 16 September 2026 · By the PayTrader team

A stage payment schedule splits a job into parts and ties each payment to one part being finished. Agree the stages, the amount for each and what "finished" means in writing before work starts. A good schedule means the money you've paid is never more than the value of the work that's been done.

Agreeing what "finished" means

Most stage payment disagreements are really about whether a stage is done. You can head these off by agreeing in advance:

What about materials?

Some stages need expensive materials bought well before the work happens, like a kitchen. You can handle this by buying them yourself, paying the supplier directly, or agreeing a materials payment against a receipt. Whatever you choose, write it into the schedule so it doesn't turn into an unplanned deposit.

When the plan changes

Jobs change: you might add a socket or find rot under a floor. Agree any extra work and its price in writing before it's done, and add it to the right stage. That keeps the schedule matching the real job.

What if a stage isn't finished?

Don't pay for a stage that isn't done. Tell the builder what's outstanding, in writing, and agree when it will be finished. If the work isn't up to standard, the Consumer Rights Act 2015 lets you ask for it to be put right or for some money back. Citizens Advice explains the steps.

How PayTrader handles this

PayTrader is built around paying stage by stage. Your stage plan lives in the app, and each stage is paid just before it starts.

  1. You and your tradesperson agree the job as stages, each with its own price.
  2. You pay for a stage before it starts. The money is held by our regulated payment provider — PayTrader never holds it.
  3. When the stage is done, your tradesperson sends photos through the app.
  4. You approve, and that stage is released to them. If you don't approve or raise an issue within 14 days of the stage being marked complete, it releases automatically; raising an issue stops the clock.

PayTrader is launching in the UK soon, for a small fee on each stage.

Common questions

How many stages should a building job have?

It depends on the size of the job. A small job might be one or two payments; a bathroom or kitchen often works well as four or five; larger projects like extensions usually have more. The aim is that neither side is ever far out of pocket.

Should I hold some money back until the end?

Many people keep a final payment for after the snag list is finished. Whatever you decide, agree it in writing before work starts so it isn't a surprise.

Can the stages change once work has started?

Yes, if you both agree. Put the change and any new price in writing before the extra work is done.
