The contract conversation nobody wants to have
Homeowners avoid contracts because they feel like distrust. In practice a contract is the opposite: it is the document that lets two people who like each other survive a bad month.

There is a moment, usually a week or two before work starts, when a homeowner decides not to raise the contract. The builder has been straightforward. The chemistry is good. Asking for paperwork now would look like suspicion.
So the job starts on a quote, an email and a handshake. For perhaps seven projects in ten, that is fine, because nothing goes badly wrong. For the other three, the absence of a contract does not cause the problem — it removes every mechanism for solving it.
The contract is not a weapon. It is the agreed answer, written in calm conditions, to questions that will be asked in angry ones.
“You are not writing a contract because you expect a dispute. You are writing it because you expect a surprise.”
What a domestic contract is really for
Strip away the legal language and a building contract answers five questions. What exactly is being built. How long it should take. When money is paid and against what. How changes are priced and agreed. And what happens when something goes wrong — delay, defect, insolvency or a disagreement about quality.
Every one of those questions will arise on your project. The only variable is whether the answer was agreed before or after the thing happened. Agreed after, the answer is a negotiation between an unhappy homeowner and a builder with your money and your unfinished house.
For most domestic work, a recognised standard form — a JCT Home Owner contract or equivalent — is enough. What matters far more than the form is that the scope, the programme and the payment schedule attached to it are the real ones.
The minimum you should have in writing
- A defined scope: the drawings and specification the price is based on
- A start date, a programme and what counts as a valid reason for extension
- A payment schedule tied to stages of work, not to dates alone
- A written procedure for pricing and agreeing changes before they are built
- Retention or a defects period, and how snagging will be handled
- Evidence of public liability and contract works insurance
Payment schedules decide who is exposed
The most common structural flaw in a domestic job is not the steel. It is a payment schedule that runs ahead of the work. Pay for the roof before it is on and you have converted your money into trust. Trust is not recoverable if the builder's other project collapses.
Stage payments should describe things a stranger could verify: foundations complete and inspected, structural frame erected, roof watertight, first fix complete, plastering complete. Dates alone are not stages; they pay for the passage of time rather than for progress.
Front-loaded deposits deserve a specific conversation. A modest mobilisation payment for materials is reasonable. Thirty per cent up front, on a domestic job, is a risk transfer to you dressed as a formality.
How to raise it without ruining the relationship
Do not present a contract as protection from the builder. Present it as protection for both of you — including from your own future requests, which are the most common cause of programme slip on a domestic job.
The wording that works: 'I want to be an easy client to work for. Can we write down the scope, the stages and how we handle changes, so neither of us has to remember what we said in March?' Good builders relax when they hear this. It is the answer to the client behaviour they fear most.
If a builder refuses any written agreement at all, that is not a personality quirk. It is information, and it has arrived at the last moment when it is still free to act on.
The last word
If work has not started, send one email confirming the scope, the stage payments and the change procedure, and ask the builder to reply confirming they agree.
That email, agreed in writing, is not a contract in the fullest sense — but on a domestic job it is worth more than everything said on site for the next six months.
