A boiler needs an organised maintenance process as well as the required safety checks. This guide was reviewed on 16 October 2026 and covers the HSE framework in Great Britain. Landlords in Northern Ireland should check the separate local requirements.
Establish the maintenance plan
HSE distinguishes maintenance responsibilities from keeping gas safety records. Its guidance says appliances and flues should be serviced according to the manufacturer's instructions. Where instructions are unavailable, HSE recommends annual servicing unless a Gas Safe registered engineer advises otherwise.
Keep the appliance details and available instructions with the property records. Ask the engineer what the proposed appointment covers and whether any further work is needed. Do not assume that two services with similar names include the same tasks.
Create a reminder early enough to arrange access and deal with any follow-up. Record the completed work, not just the booking.
Make faults easy to report
Give residents a clear contact route and explain how urgent concerns should be raised. Ask for a description of the problem and relevant information the resident can provide safely, without requesting that they open equipment or attempt repairs.
Arrange assessment by an appropriately qualified Gas Safe registered engineer for gas maintenance and repair work. Follow professional safety instructions. Do not use a routine appointment schedule as a reason to postpone responding to a potentially unsafe appliance.
Record what has been reported, who is handling it and what update the resident has received. Check after the visit whether the problem has actually been resolved.
Keep a useful service history
Bring invoices, engineer reports and follow-up notes together so that recurring problems can be understood. This can help you ask informed questions when deciding what further work to commission.
When comparing repair or replacement proposals, request a clear scope and an explanation of what is included. Avoid making the decision from an online average price or an unsupported claim about how long every boiler should last.
Review the records between tenancies and clarify the ownership of any appliance left behind. A usable maintenance history supports professional assessment and a more dependable response when something goes wrong.
