Why Bailey Gas
We don’t believe in simply taking one boiler off the wall and replacing it with another. Every installation is assessed properly, taking into account system performance, gas supply, pipework, controls, filtration and the requirements of the property.
Our aim is to leave customers with a properly designed, professionally installed heating system that performs as it should for years to come.
Our WORK
What we specialise in
Replacing older or unreliable boilers with correctly sized modern Vaillant systems.
Relocating boilers to lofts, utility rooms, airing cupboards and other suitable locations, including associated pipework and flue alterations.
Converting traditional tank and cylinder systems to modern combination boiler systems where appropriate.
New pipework, radiators, controls, filtration and improvements to existing heating systems.
For properties requiring more than a basic boiler replacement, including significant system alterations and bespoke installation work.
Our Simple Three-Step Process
Answer a few questions about your property and current heating system using our online quote tool.
Where requested, upload photos of your boiler, flue, cylinder and visible pipework so we can better understand the job.
We’ll review the details and advise on the next step for your installation.
