Heat pump repairs in Kentish Town: what to expect
Aftercare matters as much as installation. For a heat pump in Kentish Town 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.
Heat pump owners in Kentish Town can arrange a fault-finding visit at a rate agreed before an engineer attends. Across Kentish Town 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
- Heat pumps showing an error code or fault light
- Heat pumps installed by another company that need a second opinion
What's included
- Supply and fitting of replacement parts
- A clear explanation of the fault and a price for the repair before work goes ahead
- Reading of error history and operating data
- Fault-finding visit at a rate agreed before attending
- System refill, venting and recommissioning after the repair
Outdoor units in exposed spots around Kentish Town can ice more heavily, so siting is checked as part of any icing fault.
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 Kentish Town quote.

Heat pump repairs in Kentish Town: questions
How much does a visit cost in Kentish Town?
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.
Do you also cover Camden?
Yes. We arrange heat pump servicing and repairs in Camden, which is under a mile south of Kentish Town, and across Greater London.
What should I check before booking a visit in Kentish Town?
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 refrigerant repairs need a specialist?
Yes. Any work on a heat pump's refrigerant circuit, such as tracing a leak, replacing a component or re-gassing, must by law be done by an F-gas certified engineer where the refrigerant is fluorinated, such as R32; units using R290 (propane) need an engineer trained in flammable refrigerants. On split systems the refrigerant runs through pipes inside your home, so leaks there are more likely than on sealed monobloc units.
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.
