What to know about heat pump repairs in Cambridge
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.
Across Cambridge and Cambridgeshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer. We repair heat pumps in Cambridge whoever installed them, including older monobloc and split systems.
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.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Heat pumps installed by another company that need a second opinion
- Rooms or hot water not getting warm enough
What's included
- Supply and fitting of replacement parts
- Fault-finding visit at a rate agreed before attending
- Reading of error history and operating data
- Testing of sensors, pumps, valves, pressures and electrics
- A clear explanation of the fault and a price for the repair before work goes ahead
Outdoor units in exposed spots around Cambridge can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in England
Homes in Cambridge 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 Cambridge: questions
Can you work on a heat pump in Cambridge that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Cambridge, whoever fitted them. Tell us the make and model when you get in touch.
How often should a heat pump in Cambridge 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.
Do you also cover Royston?
Yes. We arrange heat pump servicing and repairs in Royston, which is about 12 miles south-west of Cambridge, and across Cambridgeshire.
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 is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
