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.
