Boiler Installation across Banbury

A new boiler installation is a significant investment in your home's comfort, energy efficiency, and long-term running costs. Whether you are replacing an old, inefficient boiler that has reached the end of its working life, upgrading from a conventional system to a modern combi boiler, or installing heating in a new extension, our Gas Safe registered engineers manage the entire process from survey to commissioning. We work with leading boiler manufacturers including Worcester Bosch, Vaillant, Baxi, and Ideal, and we help you choose the right boiler type and output for your property based on the number of bathrooms, radiators, and your hot water demand. A properly sized and installed boiler can reduce your gas bills by up to 30 per cent compared to a model that is 15 or more years old. Our installation service includes removal and safe disposal of your old boiler, installation of the new unit with any necessary modifications to gas supply, water connections, and flue routing, a full system flush to remove sludge and debris, and commissioning with a manufacturer warranty registration. Every installation is completed to Gas Safe and Building Regulations standards, and we notify your local authority on your behalf.

Boiler Installation — frequently asked questions

How long does a boiler installation take?

A straightforward like-for-like boiler replacement is typically completed in one day — usually between 5 and 8 hours. If the installation involves relocating the boiler, converting from a conventional system, or running new pipework, it may take a day and a half to two days.

What type of boiler is best for my home?

Combi boilers are ideal for most homes with one bathroom and moderate hot water demand. System boilers with a hot water cylinder suit larger properties with multiple bathrooms where simultaneous hot water use is needed. We assess your property and recommend the best option during the home survey.

What warranty comes with a new boiler?

Manufacturer warranties vary from 2 to 12 years depending on the brand and model. Worcester Bosch and Vaillant offer extended warranties of up to 10 to 12 years when installed by an accredited installer. We register the warranty on your behalf and provide all documentation.
