Expert Boiler Replacements with Minimal Disruption
If your boiler has become unreliable, inefficient or over 10 years old, replacing it could help reduce energy bills and improve heating performance.
We install new and replacement boilers across Bath for homeowners, landlords and small businesses. From modern apartments to period properties, we provide reliable installations with minimal disruption and honest advice throughout.
Heating Solutions for Period & Modern Bath Properties
Bath includes a wide range of property styles, from Georgian and Victorian homes to modern developments and flats. Many older properties require careful planning due to ageing pipework, gravity-fed systems or limited installation space.
Our engineers assess every property individually and recommend the most suitable boiler system for your home, heating requirements and budget.
Which Type of Boiler Is Right for Your Home?
We install combi, system and regular boilers across Bath, depending on your property size, heating system and hot water usage.
If you have a larger family home or a period property in Bath with multiple bathrooms, a system boiler installation (which pairs a modern boiler with a separate hot water cylinder) is often the ideal way to maintain strong hot water pressure across multiple showers simultaneously.

Boiler Servicing in Bath
An annual boiler service keeps your system running safely and efficiently — and is usually a condition of maintaining your manufacturer warranty. Our engineers carry out a full safety and performance check, including flue integrity, gas pressure, combustion readings, electrical connections and all key internal components.
