What to know about heat pump repairs in Maesteg
A heat pump that is serviced and set up properly keeps running efficiently for many years. Many heat pump faults trace back to settings, low pressure or a worn part rather than the heat pump itself, and those can usually be put right.
For repeated faults in Maesteg, the engineer looks at the system design as well as the failed part. Repairs in Maesteg that need a part ordered are explained and priced before the engineer leaves.
When a heat pump shows an error, loses pressure or stops heating, an engineer diagnoses the cause and explains the repair and its cost before fixing it.
- Heat pumps showing an error code or fault light
- Rooms or hot water not getting warm enough
- Heat pumps installed by another company that need a second opinion
What's included
- System refill, venting and recommissioning after the repair
- Fault-finding visit at a rate agreed before attending
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
- Refrigerant repairs by an F-gas certified engineer where needed
Outdoor units in exposed spots around Maesteg can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in Wales
In Wales the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Maesteg quote.

Heat pump repairs in Maesteg: questions
Do you also cover Port Talbot?
Yes. We arrange heat pump servicing and repairs in Port Talbot, which is about 5 miles west of Maesteg, and across Mid Glamorgan.
How often should a heat pump in Maesteg be serviced?
Once a year is the usual recommendation, and many manufacturers make annual servicing a condition of the warranty. Check your warranty terms for the exact requirement.
How much does a visit cost in Maesteg?
The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.
How much does a heat pump repair cost?
Heat pump repairs have a typical range of £90–£1,100, including VAT, depending on the part and labour involved. Sensor replacements sit at the lower end, while control boards and refrigerant repairs on split systems sit higher. Every repair starts with a fault-finding visit, with a guide price of £90–£180 for the first hour, and the repair is priced before work goes ahead.
Why does my heat pump keep switching on and off?
Frequent starting and stopping, called short cycling, is usually caused by an oversized heat pump, low water flow, too many zones closing at once or controls set with too narrow a range. It reduces efficiency and wears components. An engineer can check the settings, flow rates and design, and can often improve it with control changes before any parts are needed.
