What to know about heat pump repairs in Cobham
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.
Heat pump owners in Cobham can arrange a fault-finding visit at a rate agreed before an engineer attends. For repeated faults in Cobham, 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.
- Rooms or hot water not getting warm enough
- Heat pumps showing an error code or fault light
- Systems losing pressure or needing frequent topping up
What's included
- System refill, venting and recommissioning after the repair
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
- Fault-finding visit at a rate agreed before attending
Outdoor units in exposed spots around Cobham 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 Cobham quote.

Winter daylight and heating in Cobham
Cobham sees roughly 7 hours 51 minutes of daylight in late December against 16 hours 36 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.

Heat pump repairs in Cobham: questions
How often should a heat pump in Cobham 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.
How much does a visit cost in Cobham?
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 Cobham that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Cobham, whoever fitted them. Tell us the make and model when you get in touch.
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.
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.
