How the quote service works
Prefab Extension Kits is an introduction service. We neither manufacture nor sell kits. You describe the footprint you have in mind, we match it with a supplier that serves your area, and you decide whether that supplier hears from you.
Your enquiry, start to finish
Three short steps
Postcode first, then the rough size, storeys, how much building help you want and your timing, then a name with a phone number and email.
A match
We look for one supplier that makes kits of that size and delivers to your area.
Its name, first
Before the close of the next working day we contact you to say which supplier it is. At that point it has none of your details.
Your call
Agree, and the supplier receives your answers and prices the kit. Say no, and your details go nowhere.
How we are paid
When a supplier receives an enquiry through us, it pays us a fee. That is our only income. You pay nothing to use the service, whether or not you go on to order, and a supplier has no reason to price you differently because you came through us.
Things we never do
- Take money from you, for anything, at any stage.
- Quote for your kit ourselves. Pricing needs your measurements, so only the supplier can do it.
- Pass your enquiry round several firms at once. You get one name, before anything is sent.
- Put you on a marketing list.
Who you contract with
If you buy a kit, your contract, payments, delivery date and warranty are agreed directly with the supplier. We are not a party to it. Read the terms, ask in writing what the kit includes, and keep a copy of the delivery schedule.
Where our figures come from
We built every price here from 2026 UK cost guides and official fee tables, then turned them into per square metre rates for a typical home anywhere in the country. Finished-room figures include VAT. Rules on planning, building regulations and VAT come from GOV.UK and mygov.scot. Use them to plan a budget; they are neither a quote nor legal advice.

Prefab Extension Kits does not make kits. We match your footprint with one supplier covering your area, give you its name first, and only send your details when you give the word.
Thanks, that has come through.
- Next, we match your footprint to a supplier whose delivery area includes you.
- Before the close of the next working day you hear from us which supplier that is.
- If you are happy, it gets your answers and prices your kit. If not, nothing more happens.
No newsletters, no list, no calls from anyone else.
