What to know about heat pump repairs in Canterbury
Aftercare matters as much as installation. For a heat pump in Canterbury 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 Canterbury and Kent, refrigerant repairs on split systems are carried out by an F-gas certified engineer. We repair heat pumps in Canterbury whoever installed them, including older monobloc and split systems.
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
- Outdoor units that have become noisy, iced up or keep switching on and off
What's included
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
- Fault-finding visit at a rate agreed before attending
- System refill, venting and recommissioning after the repair
- A clear explanation of the fault and a price for the repair before work goes ahead
Repairs in Canterbury that need a part ordered are explained and priced before the engineer leaves.
Grants and rules for heat pumps in England
Homes in Canterbury 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 Canterbury: questions
How much does a visit cost in Canterbury?
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.
Can you work on a heat pump in Canterbury that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Canterbury, whoever fitted them. Tell us the make and model when you get in touch.
How often should a heat pump in Canterbury 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.
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.
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.
