Heat pump repairs for Derby homes
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.
Repairs in Derby that need a part ordered are explained and priced before the engineer leaves. Heat pump owners in Derby 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.
- Systems losing pressure or needing frequent topping up
- Rooms or hot water not getting warm enough
- Heat pumps installed by another company that need a second opinion
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
- System refill, venting and recommissioning after the repair
- Fault-finding visit at a rate agreed before attending
For repeated faults in Derby, the engineer looks at the system design as well as the failed part.
Grants and rules for heat pumps in England
Homes in Derby 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 Derby: questions
How often should a heat pump in Derby 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.
What should I check before booking a visit in Derby?
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.
Do you also cover Belper?
Yes. We arrange heat pump servicing and repairs in Belper, which is about 7 miles north of Derby, and across Derbyshire.
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.
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.
