How our service works
We publish price guides for annexes and, if you ask, find a firm to price yours. We are not builders. This page sets out exactly what happens to an enquiry.
What happens to an enquiry
You fill in the form
Your postcode, the kind of annexe, a rough size, who it is for and when, then a name, phone number and email.
We look for a firm
One that designs and builds annexes and takes on work in your part of the country. This usually takes a working day.
We tell you who it is
By email or phone. If you are happy, we send them your enquiry. If you are not, nothing is sent and that is the end of it.
They visit and price
The firm looks at the garden, access and ground, then gives you a written price. Any contract is between you and them.
What we are, and are not
Granny Annexe Cost is an independent guide with a free introduction service attached. We do not design, manufacture or build annexes, we do not survey gardens, and we have no connection with any annexe company that trades under a similar name.
How it is paid for
The firm we introduce pays us a fee for the introduction. You pay us nothing, whether or not you go on to build.
Things we do not do
- Ask you for money or a deposit.
- Pass your details to a firm you have not agreed to, or to more than the one we named.
- Give a price for your annexe. Only a firm that has seen the site can do that.
- Put you on a mailing list.
Where our figures come from
Build prices on this site are national guide ranges drawn from published UK builder price guides. Planning fees, VAT and council tax rules come from GOV.UK, HMRC, the Planning Portal and the legislation itself, and each page lists its sources. Use the figures to set a budget. They are not a quote, and our notes on planning and tax are general guidance, not advice on your own case.
