[email protected] reaches us for all of the following:

• Corrections. If a planning limit, a regulation reference or a cost figure on this site is wrong or out of date, tell us which page and what is wrong. We would rather fix it than leave it.
• Your data. Access, correction, deletion or withdrawal of an enquiry — see the privacy notice for what we hold and for how long.
• Complaints about a builder. We are not party to your contract and cannot arbitrate it, but we do want to know: tell us what happened and we will raise it with our lead partner, who can act on their own network.
• Press, partnerships and everything else.

We aim to reply within two working days.

What we cannot help with

We cannot tell you whether your specific extension will get planning permission, price your job, recommend a particular builder, or intervene in a dispute. For a decision on your property you need your local planning authority; for advice on your site you need a professional you have appointed.
