Investing in a new boiler can save you money and bring you peace of mind.

Replacing an old boiler with a new A-rated condensing model and heating controls could save you around £300 per year.

Running your boiler typically accounts for about half the cost of your energy bill so it makes financial sense to ensure it's running as efficiently as possible.

Our new models are all A-rated, as recommended by the Energy Saving Trust, meaning they’re some of the most environmentally friendly around.

Modern boilers come with the most advanced controls that make it easier than ever to run your heating and hot water. Our Hive Active Heating™ system even lets you control your heating on the go.

It’s also worth considering that many new models run at low noise levels and are compact in size, which is helpful if you want to change where your boiler is located in your home.

We work with our manufacturers to make sure that spare parts for our boilers are available for many years to come, so you won’t need to worry about being caught out.

If you think you need a new boiler, book an appointment with one of our expert Heating Advisers. They’ll assess your heating needs, offer you free energy-efficiency advice and a give you a fixed price quote.

Cranbrook Homeowner
Not unnaturally I expected Mick would put the new boiler in the same position as the old one : in fact it was put a bit to one side and looks wrong. I wasn't consulted about this change.

Brighton Homeowner
Our boiler installation was fantastic, James was our installer and he was polite considerate and very helful. One of the most important factors was that he was not afraid of our very excitable dogs, (Staffies), they greated him with exuberance and he recipricated.
James appreciated that we fed and watered him throughout the 2 days.
We hope that you will relay our appreciation to James; a fantastic young man.

St Ives Homeowner
The whole experience was very good. I had everything explained to me to begin with and the work was carried out with little disturbance to me. Once it was all fitted everywhere was left tidy and clean. Also I know the boiler was fitted to a high standard so I should have no problems in the future.
