Frequently asked questions

Commercial Heating — Frequently Asked Questions

Common questions about commercial heating systems in the UK.

Do commercial heating engineers need to be Gas Safe registered?

Yes. Any engineer working on gas appliances in the UK must be on the Gas Safe Register. This is a legal requirement. Always ask for a Gas Safe registration number and verify it at gassaferegister.co.uk before work begins. Compare Commercial only connects you with registered, qualified engineers.

How often should a commercial boiler be serviced?

Commercial boilers should be serviced at least annually to maintain warranty validity, energy efficiency, and compliance with health and safety regulations. High-use boilers in hotels, care homes, and large commercial buildings are often serviced twice a year. A service contract ensures regular inspection and keeps your system running reliably.

How long does a commercial boiler last?

Well-maintained commercial boilers typically last 15–20 years. Performance and efficiency decline as systems age, and replacement becomes more cost-effective than repair beyond a certain point. A qualified engineer can assess your current system and advise whether maintenance, repair, or replacement is the right decision.

What is the cost of a commercial boiler replacement?

Commercial boiler replacement costs vary widely depending on the size, type, and location of the installation. Small commercial boilers for offices start around £2,000–£5,000 installed. Large commercial systems for hotels or multi-storey buildings can run £15,000–£50,000+. Getting multiple quotes with a proper site survey is essential.

What is included in a commercial heating maintenance contract?

A standard commercial heating maintenance contract typically includes an annual service, flue and combustion analysis, safety checks, controls inspection, and a set number of reactive callouts per year. Some contracts include parts and labour; others cover labour only. Review the contract terms carefully before signing.
