How often should commercial heating systems be serviced?
Commercial heating systems should be serviced at least annually, with larger or critical systems often benefiting from bi-annual checks and a PPM contract.
Commercial Servicing Frequency
Most commercial heating and hot water systems require servicing at least once a year to remain compliant and efficient. However, larger or higher-use systems — hotels, care homes, managed apartment blocks — often benefit from bi-annual servicing, once before winter and once in spring.
Why a PPM Contract Helps
A Planned Preventative Maintenance (PPM) contract schedules these visits automatically, keeps full compliance documentation, and gives priority response if something breaks down. See our PPM Maintenance page for plan details.
