Frequently asked questions

Q. How long does a site survey take?

A: We'll need about 90 minutes for a site survey. This is in order to understand your business heating and hot water requirements, and to check your existing installation.

Q. What boiler manufacturers do you use?

A: We only install energy-efficient boilers from leading manufacturers, including Ideal, Worcester Bosch, Vaillant and Baxi. Find out more about our business boiler range.

Q. What if my boiler’s broken and I just want it repaired?

A: No problem. We can fix it with a one-off commercial boiler repair.

Q. What if I want a boiler for a residential property?

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.

[1] Product offer terms and conditions apply. This offer is available for domestic and business properties (with a total system output up to 42kW). Other boilers are available but may not qualify for this discount. We’ll give you a quote following a survey, and will let you know if the boiler you’ve chosen is eligible for the half price discount. To get the discount you must request a survey appointment by the end of 31st October 2017, either by phone or online. The discount will be applied at point of sale on the basis that we install the boiler and only applies to the boiler cost and not the cost of the installation, the flue or additional parts.
