How our service works
Timber Frame Extension is an introduction service. We publish guidance and prices for homeowners, and when someone asks for a quote we find a firm to give one. We are not builders, designers or frame makers.
The form
It asks for a postcode, the kind of extension, a rough floor area, a start date and whether drawings exist. Then a name, phone number and email.
We look for one firm
We search for a timber frame firm that takes on extensions of that kind at your postcode. One firm, not a list.
We tell you who
Within a working day we email or ring, naming the firm. Agree, and the firm receives your enquiry. Decline, and nothing is passed on.
They price the job
The firm contacts you, looks at the house and drawings, and quotes. If you go ahead, you sign with them, not with us.
Who pays
The firm does. It pays us a fee when you agree to be introduced. You are never charged, and the fee is the same whether or not anything gets built.
Things we never do
- Survey, design, manufacture or build anything.
- Hand your details to a firm you have not agreed to by name.
- Send one enquiry to several firms.
- Take a deposit, or handle money for building work.
- Add you to a mailing list.
Choosing the firm is still up to you
An introduction is not a recommendation or a guarantee. Before signing with any builder, ask for recent jobs you can go and see, proof of public liability insurance, and a written quote that lists what is excluded. Check the firm at Companies House and get a second price if the first surprises you.
Our prices and guidance
The figures on this site, including the cost calculator, are typical national ranges for 2026, including VAT; London and the South East usually cost 20 to 40% more. Planning fees are set by MHCLG from 1 April 2026. They are for budgeting. Notes on planning and building regulations summarise official guidance for England, with pointers for Scotland and Wales, and are not legal advice. Your council has the final word on your address.

Have your extension priced
Three short parts: a postcode, four questions about the job, your contact details. A minute of your time, and free.
We are an introduction service, not a builder. We look for one timber frame firm that covers your postcode, tell you which firm it is, and hand over your details only once you say yes.
That has reached us. Thank you.
Next, we look for a timber frame firm that takes on work at your postcode. Expect an email or a call from us within a working day, naming the firm.
The firm sees nothing of yours until you have agreed to it. After that they will want to see the house and any drawings before pricing. We never send marketing.
