Heat pump servicing in Cardiff: what to expect
Whoever installed your heat pump, aftercare can be arranged in Cardiff. 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 pumps in Cardiff that sit near trees or hedges often need their outdoor coil cleared of leaves at the annual service. We service heat pumps in Cardiff whoever installed them, including monobloc and split systems.
An annual service keeps a heat pump running efficiently, catches small faults early and is often a condition of the manufacturer's warranty.
- Heat pumps a year or more past installation
- Heat pumps installed by another company that need a new servicing arrangement
- Homes where running costs have crept up or rooms feel cooler than before
What's included
- Controls and error log check, with settings adjusted where needed
- Refrigerant circuit checks on split systems by an F-gas certified engineer
- Cleaning of the outdoor unit coil, fan area and condensate drain
- Glycol or antifreeze protection test where fitted
- Magnetic filter and strainer clean, with system pressure topped up
If a heat pump in Cardiff has not been serviced for a while, the first visit includes a full check of settings and pressures.
Grants and rules for heat pumps in Wales
Homes in Cardiff can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.

Heat pump servicing in Cardiff: questions
Do you also cover Penarth?
Yes. We arrange heat pump servicing and repairs in Penarth, which is about 3 miles south of Cardiff, and across South Glamorgan.
What should I check before booking a visit in Cardiff?
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.
How often should a heat pump in Cardiff 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 does a heat pump service not include?
A service covers inspection, cleaning, testing and adjustment. It does not include replacement parts, major repairs, system flushing or radiator changes, which are quoted separately if needed. If the engineer finds a fault, they explain what it is, what it would cost to fix and whether it needs doing now or can wait.
How much does a heat pump service cost?
An annual heat pump service has a guide price of £120–£250, including VAT. Where your price sits depends on the type of system, whether it is a split system needing refrigerant checks and whether an unvented cylinder is included. Any parts or repairs found during the service are explained and priced before any work goes ahead.
