A new boiler, fitted properly, in Watford

The boilers we install

We install combi, system and regular (heat only) boilers, and we fit all the major brands: Worcester Bosch, Vaillant, Ideal, Baxi and ATAG among them. The best boiler for your home depends on your water pressure, how many bathrooms you run and how you like your heating to work, and that is exactly what the survey is for.

We are Viessmann accredited engineers, so Viessmann is the brand we most often recommend when a customer asks us to choose. That is about efficiency, build quality and the extended warranty route accredited installers can offer, not about pushing one badge. You can read the honest case for Viessmann, and see how it compares with the other brands we fit, on our Viessmann boilers page.

Why Watford homeowners choose us for a new boiler

A new boiler is a big purchase, and how it is fitted matters as much as which one you buy. Our engineers design the system around your home so it runs efficiently for years, not just so it passes a first fire-up. Andrew Millward, who leads the team, has more than 40 years in the trade and carries the Heat Geek Elitist title.

A Viessmann system that does the thinking for you

This Viessmann Vitodens 200-W system went in on a job here in Watford. It runs weather compensated, with hot water priority and two heating circuits on mixers, so the system feeds heat into the home gradually as the outside temperature changes rather than blasting on and off.

That is the sort of setup that keeps running costs down without you having to think about it. You can see more of our real work in the gallery.

What a new boiler costs in Watford

Every home is different, so we quote on survey rather than quoting blind. As a rough guide, a straightforward combi replacement in the UK typically falls somewhere between £2,000 and £3,500 fitted, while a system boiler with a new cylinder, or a full change of boiler type, usually sits higher. These are typical UK ranges to help you plan, not our price; your fixed quote is confirmed once we have seen the job.

What moves the price is the boiler you choose, whether the pipework and flue need changing, where the boiler is going, and any controls or upgrades you want. Watford is a hard water area, so we will also talk to you about scale protection, which helps a new boiler stay efficient for longer.
