Underfloor Heating Repair
Underfloor heating should deliver steady, even warmth. When a wet underfloor system develops cold areas, pressure drops, leaks, or control faults, professional diagnosis is the quickest route back to reliable heating. Underfloor heating repair focuses on locating the cause, completing targeted repairs, and restoring correct flow and balance across the system.

What underfloor heating repair covers
A wet underfloor heating system relies on the manifold, pipe circuits, pump and controls working together. Repair work typically includes:
- Diagnosis of cold zones, uneven heat, and slow warm-up times
- Leak investigation, pressure-loss checks, and repair planning
- Manifold faults: valves, actuators, flow meters and isolation issues
- Pump, blending valve and temperature regulation problems
- Thermostat, wiring and control troubleshooting (where applicable)
- Flushing, air removal, inhibitor checks and system re-pressurisation
- Balancing circuits so heat is distributed evenly
When this service is most useful
Arrange an underfloor heating repair if you notice cold strips across the floor, rooms that no longer reach temperature, frequent pressure drops, or repeated air in the system. It is also suitable if the boiler runs but the floor stays cool, or if the manifold shows unusual flow readings. Landlords and small commercial sites often use this service to restore heat quickly and minimise disruption.
How the repair is carried out
The visit starts with a structured fault-find: checks at the heat source, manifold and controls, followed by pressure and flow testing to pinpoint where performance is being lost. You will then be given clear repair options, likely causes, and what access is required before work proceeds. Once repaired, the system is re-pressurised, purged of air, and tested to confirm stable temperatures and correct operation.
After the repair: performance and prevention
Many underfloor issues return when circuits are unbalanced or when air and debris remain in the system. After repair, the system can be balanced and settings verified so each loop receives the right flow. You will also get practical guidance on operating temperatures and basic checks to help maintain consistent comfort and reduce the risk of repeat faults.
