Heat pump repairs in Exeter: what to expect
Whoever installed your heat pump, aftercare can be arranged in Exeter. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Heat pump owners in Exeter can arrange a fault-finding visit at a rate agreed before an engineer attends. For repeated faults in Exeter, 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
- Systems losing pressure or needing frequent topping up
- Heat pumps showing an error code or fault light
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Fault-finding visit at a rate agreed before attending
- Reading of error history and operating data
- Supply and fitting of replacement parts
- System refill, venting and recommissioning after the repair
Across Exeter and Devon, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
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 Exeter quote.

Heat pump repairs in Exeter: questions
Can you work on a heat pump in Exeter that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Exeter, whoever fitted them. Tell us the make and model when you get in touch.
How often should a heat pump in Exeter 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 Exeter?
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 repair a heat pump installed by another company?
Yes. We carry out fault-finding and repairs on heat pumps installed by other companies, including monobloc and split systems. Tell us the make, model and approximate age when you get in touch, plus any error code shown. If the system is still under the manufacturer's warranty, it may be quicker to contact the original installer or manufacturer first.
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.
