What to know about heat pump repairs in Fleet
Whoever installed your heat pump, aftercare can be arranged in Fleet. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Outdoor units in exposed spots around Fleet can ice more heavily, so siting is checked as part of any icing fault. Heat pump owners in Fleet can arrange a fault-finding visit at a rate agreed before an engineer attends.
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
- 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
- Testing of sensors, pumps, valves, pressures and electrics
- Refrigerant repairs by an F-gas certified engineer where needed
- Fault-finding visit at a rate agreed before attending
- A clear explanation of the fault and a price for the repair before work goes ahead
- Reading of error history and operating data
Repairs in Fleet that need a part ordered are explained and priced before the engineer leaves.
Grants and rules for heat pumps in England
Homes in Fleet 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.

Short winter days in Fleet and what they mean
On the shortest day Fleet gets about 7 hours 52 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

Heat pump repairs in Fleet: questions
What should I check before booking a visit in Fleet?
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.
Can you work on a heat pump in Fleet that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Fleet, whoever fitted them. Tell us the make and model when you get in touch.
Do you also cover Farnborough?
Yes. We arrange heat pump servicing and repairs in Farnborough, which is about 3 miles east of Fleet, and across Hampshire.
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.
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.
