Landlord Boiler Responsibilities: Servicing, Repairs and How Long a Fix Can Take

In a rented home, the boiler is the landlord's responsibility. The landlord must have it checked every year by a Gas Safe registered engineer, keep it maintained in a safe condition, and repair it within a reasonable time when it breaks down. Tenants are responsible for reporting faults promptly, giving access for checks and repairs, and using the boiler sensibly. Those duties come from two main laws: the Gas Safety (Installation and Use) Regulations 1998 and section 11 of the Landlord and Tenant Act 1985.

What the Landlord Must Do by Law

The landlord has three core boiler duties: an annual gas safety check, ongoing maintenance, and repair. They apply whether the landlord manages the property personally or through an agent.

• Annual gas safety check. Every gas appliance and flue the landlord provides must be checked within every 12 months by a Gas Safe registered engineer. Existing tenants get a copy of the record within 28 days of the check, new tenants before they move in, and the landlord keeps each record for at least two years.
• Maintenance. Gas appliances, pipework and flues must be kept in a safe condition between checks.
• Repair. Section 11 of the Landlord and Tenant Act 1985 requires the landlord to keep the installations for space heating and heating water in repair and proper working order. For most tenancies of under seven years, that includes the boiler, radiators, pipework and controls.

Our page on the landlord gas safety certificate explains what the annual inspection covers.

Is a Landlord Legally Required to Service the Boiler?

Not by name. The law requires the annual gas safety check and safe maintenance; it does not use the words "annual service". In practice, a yearly service is how most landlords meet the maintenance duty.

Nearly every boiler manufacturer specifies an annual service, and the Health and Safety Executive's guidance says appliances should be maintained in line with the manufacturer's instructions. A gas safety check confirms the boiler is safe on the day. A service goes further: the engineer cleans and inspects the parts that wear, which is what prevents mid-winter breakdowns and keeps the manufacturer's warranty valid. Booking the service on the same visit as the gas safety check means one appointment per year and one set of records. If you have several properties, a boiler service plan can keep the dates on a fixed schedule. Our guide to boiler service plans for landlords sets out when a plan is worth paying for.

What the Tenant Is Responsible For

Tenants are responsible for reporting faults, letting engineers in, and not causing damage through misuse. They are not responsible for servicing or repairing a boiler the landlord provided.

Reasonable use includes topping up the system pressure if the landlord has shown them how and the boiler has an external filling loop; our guide on how to repressurise a boiler safely covers that. It does not include opening the boiler casing, which no one other than a Gas Safe registered engineer should do. A tenant who installs their own gas appliance, such as a cooker they brought with them, is responsible for that appliance; the landlord remains responsible for the boiler and for anything else they provided.

How Long Does a Landlord Have to Fix a Broken Boiler?

The law says a reasonable time, and no statute sets a fixed number of hours. What counts as reasonable depends on how serious the problem is and the time of year.

No heating or hot water in winter, especially where a child, an older person or someone unwell lives in the home, is generally treated as urgent, and many letting agents aim to have an engineer attend within 24 hours. A fault that leaves the heating working but slower to warm up can reasonably take longer. The clock starts when the landlord is told, which is why tenants should report problems in writing and keep a copy. If a part has to be ordered, a reasonable landlord keeps the tenant informed and may provide temporary heaters in the meantime.

If a landlord does not act, tenants can contact their local council's private housing or environmental health team. Councils can assess the property under the Housing Health and Safety Rating System, where excess cold is one of the listed hazards, and can require the landlord to carry out work.

Access for Checks and Repairs

Landlords must give reasonable notice before entering, normally at least 24 hours in writing, except in an emergency such as a gas leak. Tenants should allow access at a reasonable time for the gas safety check, servicing and repairs.

If a tenant repeatedly refuses access for the annual check, the landlord must be able to show they took all reasonable steps to get it done. Keep a record of every letter, email and appointment offered. A landlord who has tried and been refused is in a very different position from one who never booked the check. Our article on managing agent versus landlord gas safety responsibility covers who should be arranging access when an agent is involved.

Who Pays for the Service, the Check and Repairs?

The landlord pays for the annual gas safety check, routine servicing and repairs to a boiler they provided. These costs cannot be passed to the tenant as a separate charge during the tenancy.

The exception is damage the tenant caused, such as a boiler damaged by misuse, where the landlord may be able to recover the cost. Normal wear and tear, including parts that fail with age, is the landlord's cost. Budgeting for the annual check and service as a fixed yearly expense, and keeping every service record, is also the best evidence you can have if a dispute or a council inspection ever arises. If you let a property in London, we can carry out the gas safety check and the service on the same visit.
