Gas Safe engineer mounting a new boiler onto a wall

5 out of 5 stars

Needed a new boiler urgently after our old one packed up completely. The team installed a Worcester Bosch combi in one day and explained everything clearly. Heating bills have dropped significantly too.

Boiler Installation FAQs

How long does a boiler installation take?

Most boiler installations take 1-2 days depending on the complexity. A straight swap of a combi boiler typically takes one day, while converting from a system to a combi boiler or installing in a new location may take longer.

What's included in your boiler installation service?

Our installation includes removing your old boiler, installing the new boiler with all necessary pipework and controls, system flushing, commissioning, and a full demonstration of your new system. We also handle all certification and warranty registration.

Do you help choose the right boiler for my home?

Absolutely. We assess your property size, hot water usage, existing heating system, and budget to recommend the most suitable boiler. We'll explain the benefits of different brands and models to help you make an informed decision.

What warranties do you provide on boiler installations?

All our installations come with manufacturer warranties (typically 5-10 years) plus our own workmanship guarantee. We also provide ongoing support and can arrange annual servicing to maintain your warranty.

Can you install a boiler in a different location?

Yes, we can relocate boilers to more convenient positions, such as moving from a bedroom to a cupboard or loft space. We'll assess the feasibility and provide a detailed quote for any additional work required.
