How do you repair underfloor heating?

Repairs typically start with diagnostics to locate the fault, followed by replacing or repairing the affected components and testing the system to ensure consistent heat.

Is it expensive to repair underfloor heating?

Costs depend on the type of system, the fault and the parts involved. Many repairs are more affordable than replacing the system.

How much does underfloor heating cost to repair?

Repair costs vary depending on the type of system, the fault and any parts required. In most cases, repairing an existing system is more cost-effective than replacing it completely. Contact us if you would like guidance on expected repair costs.

Do you need to remove flooring to repair underfloor heating?

Not always. Many faults can be located and repaired using diagnostic tools without lifting the entire floor. If lifting is required, it is usually localised.

How long does an underfloor heating repair take?

Diagnostics usually take under an hour. Most repairs can be completed in a single visit unless specialist parts are required.

Which is easier to repair, electric or water-based underfloor heating?

Electric systems are generally simpler, while wet systems offer better long-term efficiency but involve more components such as pumps and manifolds.

How do you repair an underfloor heating pipe?

Repairing a water-based (wet) underfloor heating pipe typically involves identifying the leak or damaged section, isolating the system, and replacing or repairing the affected pipework. The challenge with pipe repairs is locating the fault beneath flooring and ensuring the system can be rebalanced afterwards. Because these systems operate under pressure and often sit beneath finished floors, repairs are normally carried out by qualified heating engineers or plumbers.

How do you repair an electric underfloor heating cable?

Electric (dry) underfloor heating repairs usually begin with fault-finding to locate the damaged cable, sensor or mat. Specialist equipment can detect breaks under the floor so repairs can be made without removing the entire surface. Once the fault is identified, the damaged section can be replaced and the system tested to ensure even heat distribution. Due to electrical safety and the risk of damaging cables further, repairs should be carried out by an experienced electrician.

Should I repair or replace my underfloor heating?

Repairs are usually more cost-effective than replacing the entire system, especially if the issue is isolated to a cable, thermostat, pump, manifold or control unit. In many cases, underfloor heating continues to perform well once the faulty component has been repaired or replaced.

Replacement is normally only considered if the system is very old, poorly installed, or uses components that are no longer compatible with modern controls. The decision can also depend on the type of flooring, the age of the property and whether renovation work is already planned.

Diagnostics will help determine the most sensible approach by identifying the source of the problem and the condition of the wider system. This allows you to compare the cost and disruption of repair versus a full replacement based on accurate information.

Do landlords need to repair underfloor heating for tenants?

According to UK government guidance, underfloor heating is installed as the primary heat source in a rental property, the landlord is usually responsible for ensuring it remains operational. Faults that lead to no heat, uneven temperatures or inefficiency may require repair to meet rental expectations and heating standards.

Where underfloor heating is a secondary comfort feature, the obligation can depend on the tenancy agreement, the age of the system, and whether it was included as a stated amenity. Diagnostics can help determine whether repair is straightforward or linked to wider building or renovation work. Maintracts supports landlords and agents by assessing and repairing both electric and water-based systems in London rental properties.
