Heat pump repairs in Fareham: what to expect
Aftercare matters as much as installation. For a heat pump in Fareham 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 Fareham and Hampshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer. Repairs in Fareham that need a part ordered are explained and priced before the engineer leaves.
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.
- Systems losing pressure or needing frequent topping up
- Rooms or hot water not getting warm enough
- Heat pumps showing an error code or fault light
What's included
- A clear explanation of the fault and a price for the repair before work goes ahead
- Supply and fitting of replacement parts
- Reading of error history and operating data
- Refrigerant repairs by an F-gas certified engineer where needed
- Testing of sensors, pumps, valves, pressures and electrics
Outdoor units in exposed spots around Fareham 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 Fareham quote.

Short winter days in Fareham and what they mean
Fareham sees roughly 7 hours 56 minutes of daylight in late December against 16 hours 31 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.
What happens when you book in Fareham?
- 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 Fareham.
- 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 Fareham: questions
Can you work on a heat pump in Fareham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Fareham, whoever fitted them. Tell us the make and model when you get in touch.
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 Gosport?
Yes. We arrange heat pump servicing and repairs in Gosport, which is about 4 miles south-east of Fareham, and across Hampshire.
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.
Why is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
