Why efficiency matters

How much can a new boiler save you?

An older boiler wastes up to 40% of the gas you pay for. A new A-rated model uses over 90%, so your bills drop straight away. The Energy Saving Trust estimates you could save around £420 a year in Great Britain by upgrading from a G-rated boiler to an A-rated boiler with full heating controls.

Your installation

One price. Everything included.

Need it now?

No hot water, boiler cutting out, strange noises? We can go from quote to a fitted boiler in 3–5 days. You don't need to know what type you have - we work that out from a few photos.

Planning ahead?

If your boiler is 10 to 15 years old, it's losing efficiency every winter. Replacing it before it fails means no emergency, lower bills, and a warranty that starts while everything still works.

  • A-rated boiler from Worcester Bosch, Vaillant, Ideal, Baxi or Viessmann

    Matched to your home size and hot water demand.

  • Gas Safe registered installation

    Notified to your local authority on completion.

  • Full system power flush and magnetic filter

    Clears sludge and protects the new boiler from day one.

  • Flue, pipework, and all fittings

    Nothing left off the quote for you to source separately.

  • Manufacturer warranty up to 10 years

    Plus our own 2-year workmanship guarantee, double the industry standard.

  • Old boiler removed and disposed of

    Taken away on the day, nothing for you to arrange.

How it works

Three steps to a new boiler

No home visit needed for most installations. From quote to a fitted boiler in around 3–5 days.

01

Answer a few questions

Tell us about your home, your current boiler, and upload a few photos. Takes a couple of minutes.

02

Get a fixed price

You'll see your all-in price straight away, matched to the right boiler for your home. No obligation.

03

We fit it properly

A Gas Safe registered engineer installs your boiler, flushes the system, sets up your controls, and walks you through everything.

On the day

What happens on installation day?

Most boiler swaps take a single day. Here's how long the engineer is on site, what you need to prepare, and what happens before they leave.

A combi swap is usually done in a single day. System conversions (e.g. removing old tanks) can take 1–2 days.

5.0
from Google Reviews

"New combi boiler fitted in a day. The engineer was on time, laid dust sheets everywhere, and left the kitchen spotless. Boiler is whisper-quiet compared to the old one."

Sarah M.

"Went from an ancient back boiler to a new Worcester Bosch combi. The engineer was here for a day, walked us through the controls, and the house has never been this warm."

James T.

"Had an old back boiler converted to a combi. Took two days and the team talked us through every step. The 10-year warranty gives real peace of mind."

Helen R.

"Quick quote, fair price, no upselling. Engineer showed up early and was finished by lunchtime. Couldn't fault the service."

Mark P.

"Old boiler died on a Friday. By Wednesday we had a brand new Ideal Logic fitted. Saved us a freezing weekend."
