Heat pump repairs in Gillingham: what to expect
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.
We repair heat pumps in Gillingham whoever installed them, including older monobloc and split systems. For repeated faults in Gillingham, the engineer looks at the system design as well as the failed part.
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 installed by another company that need a second opinion
- Systems losing pressure or needing frequent topping up
- Outdoor units that have become noisy, iced up or keep switching on and off
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Fault-finding visit at a rate agreed before attending
- Supply and fitting of replacement parts
- System refill, venting and recommissioning after the repair
- Testing of sensors, pumps, valves, pressures and electrics
Repairs in Gillingham that need a part ordered are explained and priced before the engineer leaves.
Grants and rules for heat pumps in England
Homes in Gillingham 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.
What to budget for heat pump repairs in Gillingham
Guide prices for Kent, including VAT. We agree the visit rate before anyone attends, so there are no surprises on the day.
| Repair | Guide price |
|---|---|
| Fault-finding visit and diagnosis | £90–£190 |
| Sensor or thermistor replacement | £120–£290 |
| Expansion vessel or pressure relief valve | £150–£360 |

Inc VAT. The fault-finding rate is agreed before we attend; repairs are priced in writing before parts are ordered.
Designing for Gillingham's winters
Gillingham sees roughly 7 hours 51 minutes of daylight in late December against 16 hours 37 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.
How a visit works in Gillingham
- Tell us the make if you know it, the error code or symptoms, and send photos of the unit and controller.
- We confirm the fault-finding rate and arrange a visit in Gillingham.
- The engineer diagnoses the fault and gives you a written price for the repair.
- Parts are ordered once you agree, and the repair is completed and tested.
Heat pump repairs in Gillingham: questions
What should I check before booking a visit in Gillingham?
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.
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.
Do you also cover Rochester?
Yes. We arrange heat pump servicing and repairs in Rochester, which is about 2 miles west of Gillingham, and across Kent.
Is ice on my heat pump a fault?
Some frost on the outdoor unit in cold, damp weather is normal, and the unit clears it with regular defrost cycles, often releasing a little vapour. It becomes a fault when thick ice builds up and does not clear, or when ice blocks the fan. That can point to poor airflow, a failed sensor, drainage problems or low refrigerant, and needs checking.
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.
