How our service works
Steel Frame Extension puts homeowners in touch with a firm; it does no design, fabrication or building of its own. This page sets out what happens after you press send.
You send the form
Your postcode, the kind of steelwork or extension, a rough floor area, how far the drawings have got, and a phone number or email.
We look for one firm
A fabricator-builder or extension specialist that takes on jobs of your type and travels to your postcode. One firm, not a list.
We tell you who it is
By phone or email, within a working day where we can. You decide whether they may have your enquiry.
They survey and price
If you say yes, they arrange a visit and send their own quotation. Any contract after that is between you and them.
Who pays
The firm. Once you have agreed to the introduction, that firm pays us a fee for it. Using the site costs you nothing, and that stays true whether you build or not.
Where our part stops
- We do not hand your enquiry to several companies, or to anyone you have not approved.
- We never price a job ourselves; that needs someone on site.
- We do not take deposits or payments of any kind.
- We do not email you offers or newsletters.
The figures on this site
Prices are typical national ranges for 2026, including VAT; London and the South East usually cost 20 to 40% more. They are there to tell you whether a plan is in the right territory; a real figure comes from a visit. What we say about planning and building regulations rests on GOV.UK, the Scottish Government and the steel industry’s technical bodies, listed at the foot of each page. Treat all of it as background for a conversation with your designer and engineer, never as a quotation or as legal advice.
No connection with similar names
Several building companies trade under names close to this site’s. We are independent of all of them.

Three short steps. Your postcode, four questions about the job, then how to reach you.
We are an introduction service, not a steel frame extension specialist. We look for a single firm working in your area, give you its name, and hold your details back until you give the go-ahead.
Received, thank you.
- Within a working day we come back with the name of one firm that takes on steel-framed work in your area.
- Nothing goes to that firm unless you tell us to go ahead.
- If you do, they come out, measure and send their price. We send no marketing of any kind.
