Before you book: heat pump repairs in Cheshunt
Aftercare matters as much as installation. For a heat pump in Cheshunt 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.
Across Cheshunt and Hertfordshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer. Outdoor units in exposed spots around Cheshunt can ice more heavily, so siting is checked as part of any icing fault.
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
- Outdoor units that have become noisy, iced up or keep switching on and off
- Heat pumps showing an error code or fault light
What's included
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
- Supply and fitting of replacement parts
- Refrigerant repairs by an F-gas certified engineer where needed
- System refill, venting and recommissioning after the repair
Repairs in Cheshunt that need a part ordered are explained and priced before the engineer leaves.
Grants and rules for heat pumps in England
Homes in Cheshunt can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Heat pump repairs in Cheshunt: questions
Will the engineer need access indoors as well as outside?
Usually yes. The outdoor unit, the hot water cylinder, the controls and the pipework and valves indoors are all part of the visit, so allow access to each.
How much does a visit cost in Cheshunt?
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 Cheshunt?
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.
Can you repair a heat pump installed by another company?
Yes. We carry out fault-finding and repairs on heat pumps installed by other companies, including monobloc and split systems. Tell us the make, model and approximate age when you get in touch, plus any error code shown. If the system is still under the manufacturer's warranty, it may be quicker to contact the original installer or manufacturer first.
