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.

Coventry GB
The adviser and gas installer were lovely and very thorough. They were tidy and friendly and did their work to a high standard. The electrician however, did not introduce himself to us at all and did not fit a new fuse spur as requested (and charged for), he simply used the old one which we had disconnected as we did not know what it supplied(which we would have informed him of had he botherd to talk to us). He also did not fit the cable to the wall securely.

Overall we were very satisfied with our new boiler and the work done by the gas engineer, but bitterly disappointed with the electrician. Also happy that the work was done promptly as we had a small baby to keep warm and no heating or hot water prior to this.
