Boiler installations, made easy.

A new boiler, including professional installation, typically costs between £1,500 and £4,500. The exact price depends on factors such as the boiler type, brand, property size, location, and number of bathrooms. Combi boilers are usually the most cost-effective option, while system or regular boilers may cost more due to additional components or pipework.

iHeat installs a wide range of combi, system, and heat-only boilers from trusted British and European brands, including Worcester Bosch, Vaillant, Viessmann, Alpha, and more. All boilers are energy-efficient, reliable, and installed by Gas Safe engineers to ensure top performance and peace of mind.

Most combi-to-combi boiler replacements are completed within one day, while more complex installations or boiler conversions can take up to two days. The exact time depends on factors such as the boiler type, property layout, and location of the existing system. All installations are carried out efficiently by Gas Safe engineers to minimise disruption to your home.

Our Gas Safe engineers will arrive on the date you selected, usually between 7am-9am, and will proceed to:

• 1. Remove and replace your old boiler with a new, efficient model.
• 2. Chemically flush the heating system.
• 3. Install new pipework or equipment as needed.
• 4. Conduct thorough tests.
• 5. Dispose of the old boiler safely.

Once installation is finished, your Gas Safe engineer will carry out final safety and performance checks to ensure everything is working perfectly. They’ll then complete all required paperwork and registration, including your warranty and Building Regulations certificate, and show you how to use your new boiler and controls. You can then relax and enjoy a warm, efficient home.
