How our service works
We neither design nor build. We introduce homeowners in England, Scotland and Wales to a firm that puts up two storey extensions from factory-made panels or modules, at no cost to them. Here is the whole process, start to finish.
You fill in the form
The postcode, the shape of the extension, a rough floor area, where you are with planning and when you would like to start, then your name and number.
We find a firm
We look for one firm that puts up two storey extensions from factory-made panels or modules, and covers your area.
You hear its name first
We ring or email to tell you who it is. If you agree, the firm gets your enquiry. If not, nothing more happens.
The firm prices it
Someone from the firm visits, looks at the ground and the route for a crane, and gives you a figure. If you sign, the contract is with them, not us.
What we are
A small introduction service, run by Joe Trewick trading as Grub Leads. We have no connection with any business whose name looks like ours. The design, the factory work, the delivery and the building are all done by the firm you pick.
What we do not do
- Charge you anything, now or later.
- Pass your enquiry on before you have agreed, or to any firm beyond the one we named to you.
- Price your extension ourselves. That needs a builder on site.
- Put you on a mailing list.
Who pays for it
The firm you are introduced to pays us a fee for each introduction. It costs you nothing, and nothing changes if you decide not to go ahead.
About the figures and guides
Our price ranges are national 2026 figures with VAT included, drawn from published UK cost guides and from council and government fee tables. The planning and building notes follow GOV.UK and the Scottish and Welsh Governments. Use them for budgeting. A firm's price for your house will differ, and nothing here is legal advice.

We are an introduction service, free to you, and we do not build. Once we have found a firm near you that puts up two storey extensions, we tell you who it is, and your details stay put until you give the go-ahead.
Got it. Your enquiry has arrived.
- We search for a firm that puts up two storey prefab extensions in your part of the country, then get in touch to tell you who it is.
- Nothing goes to that firm unless you agree.
- The firm visits, looks at the ground and the access for a crane, and prices the job. We never send marketing.
