If your boiler has broken down, become unreliable, or is over 10 years old, replacing it could significantly improve efficiency and reduce energy bills. Older boilers are often more expensive to run and more prone to faults.
We carry out boiler installations across a wide range of properties in Bath, including period homes, modern houses and flats, rental properties and commercial premises. From your first call through to final handover, we focus on providing a clean, professional and reliable service every time.
Bath has a distinctive mix of housing, from Georgian and Victorian properties to post-war homes, modern developments and apartments. Many older homes were built long before modern central heating systems existed, which means boiler installations often require additional care and experience.
We regularly work on Bath properties with older pipework, gravity-fed systems, limited cupboard or loft space, and layouts that need thoughtful system design. Our engineers assess each home individually and recommend boiler solutions that suit both the property’s structure and current energy-efficiency standards.
Whether you’re upgrading an ageing boiler in a period property or installing a new system in a modern home, we ensure the installation is safe, efficient and fully compliant.
