How our service works
We are not a panel manufacturer or a building firm. This is a free service that puts homeowners in England, Wales and Scotland in touch with a company that designs and erects SIPs extensions. Here is exactly what happens to an enquiry.
You fill in the form
Your postcode, what you want priced, a rough floor area, how far your drawings have got and when you hope to start. Then a name, phone number and email.
We look for a SIPs firm
One that designs and erects panel extensions and takes on work at your postcode. We aim to come back to you within a working day.
We tell you who it is
By phone or email. If you like the sound of them, we pass your enquiry across. If you do not, nothing is sent and we delete it on request.
They price your extension
From your drawings or a visit. Any contract, deposit and payment is between you and that company.
What we are not
We do not manufacture panels, employ fitters or carry out surveys, and we have no connection with any panel maker or builder whose name resembles ours. The design, the engineering and the building work are the responsibility of the firm you appoint.
Things we will not do
- Ask you for money, now or later.
- Send your details to a firm before you have agreed to it, or to more than the one we named.
- Give you a price for your job. Only a firm that has seen the drawings can.
- Put you on a mailing list.
How we earn money
The firm pays us a fee when you agree to be introduced. It costs you nothing, and the fee is the same whether or not you go on to build.
Our prices and guides
Cost figures here 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. Planning and Building Regulations notes come from GOV.UK, the Planning Portal and the Scottish Government, and structural notes lean on the Approved Documents and trade-body guidance. They are there to help you budget and ask better questions. They are not a quotation, and they are not legal or engineering advice for your house.

Postcode, four quick questions about the build, then how to reach you. It takes about a minute and costs nothing.
We match homeowners with panel firms, free of charge, and do not build extensions ourselves. We look for a company that designs and erects SIPs extensions near your postcode and tell you its name. Your details go no further until you say yes.
Thank you. That is all we need for now.
- We look for a firm that builds SIPs extensions around your postcode, then ring or email you with its name, normally within a working day.
- If you are happy with that firm, say so and we pass your enquiry to them. If not, it ends there.
- They ask for your drawings or come and measure, then price the job. We never send marketing.
