Replacing your older, less efficient business boiler can dramatically improve your Energy Performance Certificate (EPC) rating and can help to reduce your overall energy consumption.
Older boilers become difficult to service after a while, and replacement parts are difficult to source. Also, a new boiler is more reliable and is less likely to breakdown.
Modern temperature control devices so that you can be precise about how you heat each area of your business.
Book a nationwide appointment for one of our Commercial Boiler advisors to come and help you find the right boiler for your business, which an expert Gas Safe registered engineer will then install. If you need any additional items like a full heating system, replacement radiators, thermostatic radiator valves or additional pipework, we can also assess this for you.

After your free site visit, our Commercial Boiler Advisor can help you decide the perfect gas boiler for your business.
When choosing between a combi or system boiler, here's some of the key features you'll have to consider
A: We only install energy-efficient commercial boilers from leading manufacturers, including Ideal, Worcester Bosch, Vaillant and Baxi.
A: No problem. We can fix it with a one-off commercial boiler repair.
A: Most boilers for residential homes have outputs of less than 70 kW and you can get quotes for these through the new boiler page on our residential site.
If you need a boiler with an output greater than 70 kW, you're in the right place – contact our commercial boiler team, using the details above.
A: Commercial boilers are usually larger than domestic boilers and if your business property needs an output greater than 70kW, you'll need a commercial boiler for your heating. Commercial properties usually have bigger gas boilers, or non-domestic appliances and larger pipework, which a domestic engineer isn’t qualified to work on.
