The core pages are the installer check sheet, using the MCS register, comparing quotes, consumer codes, warning signs and questions for the survey visit.

A note on what these guides do not do
None of these guides names, rates or recommends an installer, and none of them can tell you a particular firm is good. They explain where to look and what to ask, so that you can make that judgement yourself with evidence you have checked. Each guide links to the official register or code it relies on, and shows the date it was last checked against that source.
If a guide raises a question it does not answer, the form below reaches the publisher. We reply by email, and what you send is read by the publisher, not by installers.
A reading order for a first-time buyer
If heat pumps are new to you and you would like to read in order: start with what MCS certification covers, then competent person schemes, so you know what each register proves. Read claims in adverts and reading reviews before you contact firms, and deposits and payments before you sign. Keep cancelling a contract and complaints and disputes for later; with luck you will not need them.
When an installer says something different
If an installer tells you something that contradicts a guide here, ask it to show you the rule or register it is relying on. Rules do change and a page here may be out of date; equally, a firm may be mistaken. The official source settles it either way, and we would like to hear about it.
