Terms of Use

Last updated 23 September 2026

These terms apply to your use of Boiler Decoder at https://boilerdecoder.co.uk/. Please read them alongside our disclaimer and privacy policy.

Acceptance of these terms

By using this website you agree to these terms. If you do not agree with them, please do not use the site. We may update the terms from time to time, and the version on this page is the one that applies when you visit.

Information only

Everything on this site is general information about boiler fault codes and common heating problems. It is not professional advice, it is not a diagnosis of your boiler, and it does not create any professional or contractual relationship between you and us. You should not rely on it as a substitute for advice from a qualified engineer who has inspected your system.

Gas safety

In the UK it is a legal requirement that anyone working on gas appliances, including boilers, is registered with Gas Safe Register. Our guides only describe simple checks that manufacturers expect homeowners to carry out, such as reading the pressure gauge, using the filling loop, pressing reset or thawing a frozen condensate pipe. You must never remove the boiler casing or attempt to repair gas, electrical or flue components yourself.

If you smell gas or suspect a carbon monoxide leak, leave the property and call the National Gas Emergency Service on 0800 111 999 (0800 002 001 in Northern Ireland).

Accuracy and model differences

We research our content from manufacturer documentation and take care to keep it accurate and up to date. However, fault codes and their meanings can differ between models, production years and software versions, and manufacturers can change them without notice. We do not guarantee that any page is complete, correct or current for your particular boiler. Always check your boiler's own manual, and ask a Gas Safe registered engineer if you are unsure. Prices we mention are typical ranges for guidance, not quotes.
