How Much Does It Cost to Replace a Back Boiler?

"If you live in an older home, chances are you've heard of a back boiler. These were popular heating systems installed behind fireplaces. They provided hot water and heating by burning gas or solid fuel. But today, back boilers are outdated, inefficient, and even unsafe. So, if you still have one, you might be thinking about replacing it. But how much does it cost to replace a back boiler?"

"A back boiler is a small boiler unit that sits behind a fireplace or stove. It heats water for radiators and taps. It became popular in the UK in the 1960s and 70s. These boilers worked well at the time. But over the years, they've proven to be less energy-efficient and harder to maintain than modern systems. Many back boilers are no longer supported or are illegal to repair due to safety rules."

Back boilers are compact boiler units installed behind fireplaces or stoves to heat water for radiators and taps. They were commonly fitted in UK homes in the 1960s and 70s. Many back boilers now show low energy efficiency—around 70%—compared with modern condensing boilers that exceed 90%, leading to higher fuel bills. Several models, including some Baxi Bermuda units, present safety risks such as cracks, leaks, and carbon monoxide escape. Replacement parts and qualified engineers are increasingly scarce. Replacement decisions depend on the new system chosen, existing system condition, and the property's size, and may involve legal compliance.
