A tenant reports that the boiler has stopped working just as the weather turns cold. You arrange to look into it, but the repair takes longer than expected. How long can you wait before the delay becomes a legal problem?
As per landlord heating obligations UK, landlords have a legal duty to keep heating and hot-water installations in repair and proper working order. Knowing what this means can help you respond before a small fault becomes a bigger problem.
What Are Your Legal Heating Obligations as a Landlord?
Under Section 11 of the Landlord and Tenant Act 1985, landlords covered by the law must keep installations for space heating and heating water in repair and proper working order.
This generally means dealing with faults involving:
-
Boilers and central heating systems.
-
Radiators and associated heating pipes.
-
Hot-water systems and relevant installations.
You cannot simply transfer a legal repair duty to your tenant through a tenancy agreement. However, the circumstances matter. For example, a tenant may be responsible for damage they have caused, whilst normal wear and tear or a fault with the heating system will generally need to be addressed by the landlord.
Broken Boiler? How Quickly Must You Act?
There is no rule requiring every landlord to replace a broken boiler within 24 hours. The time allowed for a repair depends on the circumstances, including the seriousness of the fault, the weather and the impact on the tenant.
A heating failure during freezing weather may require a much faster response than a minor issue that does not affect the property's ability to stay warm. If a tenant reports a heating problem, take these steps:
-
Acknowledge the report. Record when the tenant contacted you and what has stopped working.
-
Assess the urgency. Find out whether the property has heating and hot water, and consider the needs of anyone living there.
-
Arrange a qualified contractor. For gas appliances, use a Gas Safe registered engineer where required.
-
Keep the tenant informed. Explain the next steps and provide updates if parts or replacement equipment cause delays.
-
Keep records. Save messages, contractor reports, appointments and invoices.
If the repair cannot be completed immediately, consider whether a safe temporary arrangement is appropriate. This does not remove the need to address the underlying fault.
Is There a Minimum Temperature for a Rented Property?
Landlords often hear that rental homes must reach 21°C in living rooms and 18°C in other rooms. These figures are associated with guidance on assessing excess cold under the Housing Health and Safety Rating System (HHSRS). They should not be treated as a simple statutory minimum that applies identically to every rented property.
The key issue is whether the home can be heated adequately and whether cold conditions create a health or safety risk. The government's guidance on keeping a rented home safe explains that landlords must provide adequate heating in proper working order. Insulation, draughts, broken windows and the overall condition of the property can also affect how well it retains heat.
If a tenant says the property is consistently too cold, investigate the cause rather than assuming the heating system is sufficient because it switches on.
Gas Safety Check or Boiler Service: What's the Difference?
A gas safety check is a legal requirement for relevant gas appliances and flues provided by the landlord. It must be carried out at least every 12 months by a Gas Safe registered engineer. Landlords must keep the record and give a copy to existing tenants within 28 days of the check, and to new tenants before they move in.
A boiler service is routine maintenance intended to help keep the boiler working efficiently and identify developing faults. Although an annual service is recommended good practice, it is not the same as the statutory gas safety check.
The Health and Safety Executive's landlord gas safety guidance explains these safety responsibilities. Keeping up with maintenance can help you identify problems earlier, although it cannot guarantee that a breakdown will never happen. For more detail, read our guide to the landlord gas safety certificate and boiler service.
What Happens If You Ignore Heating Problems?
Ignoring a reported heating fault can put tenants' comfort and wellbeing at risk. Cold conditions may also contribute to damp and mould problems, although the underlying cause should always be investigated.
Depending on the circumstances, unresolved heating problems may lead to:
-
Complaints to the local council.
-
An inspection and possible enforcement action if serious housing hazards are identified.
-
Disputes or legal claims relating to the property's condition.
-
More extensive repairs if a fault is allowed to worsen.
-
Strained tenant relationships and avoidable management costs.
There is no single penalty that automatically applies to every delayed heating repair. The outcome depends on the facts, the condition of the property and whether the landlord has met their legal duties.

Keeping on top of maintenance takes time, especially if you manage several rental properties or live away from your investment. Missed messages, contractor delays and incomplete records can make an already stressful repair harder to manage.
