Is the Landlord Responsible for Boiler Repairs?
In short, YES, if you are a tenant, the responsibility for boiler repairs typically falls on the landlord's shoulders. Landlords are obligated to ensure that heating and hot water systems are in excellent working order, as outlined in most tenancy agreements.
Key responsibilities include:
- Addressing boiler faults within a reasonable time frame (typically 24 hours)
- Ensuring annual Gas Safe inspections
- Keeping repair records for safety compliance
Homeowners, on the other hand, must arrange their own servicing and repairs to stay compliant and safe.
Landlords and the Law
Landlords need to be aware of their responsibilities regarding boiler repairs.
Therefore, neglecting these duties can not only result in inconvenience for tenants but also legal consequences. Make sure to keep up-to-date records of all maintenance and repair work done on the boiler for documentation purposes.
For landlords, dealing with a broken boiler and arranging repairs can be a substantial challenge, especially if it happens during the winter months.

- Major faults (e.g., pump or valve replacement): several hours or more
To minimise downtime:
