What to know about heat pump repairs in Uxbridge
Aftercare matters as much as installation. For a heat pump in Uxbridge the visit checks the outdoor unit, the water circuit and the controls, and the engineer explains any settings that would help the system run more efficiently.
Outdoor units in exposed spots around Uxbridge can ice more heavily, so siting is checked as part of any icing fault. Across Uxbridge and Greater London, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
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.
- Rooms or hot water not getting warm enough
- Systems losing pressure or needing frequent topping up
- Heat pumps showing an error code or fault light
What's included
- Reading of error history and operating data
- A clear explanation of the fault and a price for the repair before work goes ahead
- Supply and fitting of replacement parts
- Refrigerant repairs by an F-gas certified engineer where needed
- Testing of sensors, pumps, valves, pressures and electrics
Heat pump owners in Uxbridge can arrange a fault-finding visit at a rate agreed before an engineer attends.
Grants and rules for heat pumps in England
In England 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), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Uxbridge quote.

Heat pump repairs in Uxbridge: questions
How much does a visit cost in Uxbridge?
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.
What should I check before booking a visit in Uxbridge?
Note any error code on the controller, check the system pressure gauge if you have one, and make sure the outdoor unit is clear of leaves or snow. Photos of the unit and controller help.
Do you also cover Ruislip?
Yes. We arrange heat pump servicing and repairs in Ruislip, which is about 3 miles north-east of Uxbridge, and across Greater London.
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.
