Before you book: heat pump repairs in Arundel
Whoever installed your heat pump, aftercare can be arranged in Arundel. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
We repair heat pumps in Arundel whoever installed them, including older monobloc and split systems. For repeated faults in Arundel, 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
- Rooms or hot water not getting warm enough
What's included
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
- System refill, venting and recommissioning after the repair
- Refrigerant repairs by an F-gas certified engineer where needed
Heat pump owners in Arundel can arrange a fault-finding visit at a rate agreed before an engineer attends.
Grants and rules for heat pumps in England
Homes in Arundel 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.

Heat pump repairs in Arundel: questions
Can you work on a heat pump in Arundel that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Arundel, 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.
How often should a heat pump in Arundel 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 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.
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.
