How often should I replace my boiler?

Modern boilers typically last 12–15 years. If your boiler is over 10 years old and efficiency has dropped below 85%, or you are facing frequent breakdowns, replacement is usually more cost-effective than ongoing repairs.

What is a Gas Safe engineer?

Gas Safe is the official UK register for gas engineers. Only Gas Safe registered engineers are legally allowed to work on gas appliances such as boilers, cookers, and fires. You can verify registration at GasSafeRegister.co.uk.

Should I choose a combi, system, or conventional boiler?

Combi boilers suit smaller homes with 1–2 bathrooms — no tank needed. System boilers suit larger homes with multiple bathrooms, using a hot water cylinder. Conventional boilers suit older properties with existing gravity-fed systems.

How much does a powerflush cost?

A powerflush typically costs £350–£600 depending on the number of radiators. It cleans sludge and debris from your central heating system, improving efficiency and extending the life of your boiler.
