Heat pump repairs in Blackheath: what to expect
Whoever installed your heat pump, aftercare can be arranged in Blackheath. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Repairs in Blackheath that need a part ordered are explained and priced before the engineer leaves. Outdoor units in exposed spots around Blackheath can ice more heavily, so siting is checked as part of any icing fault.
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 showing an error code or fault light
- Rooms or hot water not getting warm enough
- Heat pumps installed by another company that need a second opinion
What's included
- A clear explanation of the fault and a price for the repair before work goes ahead
- Supply and fitting of replacement parts
- Fault-finding visit at a rate agreed before attending
- Testing of sensors, pumps, valves, pressures and electrics
- System refill, venting and recommissioning after the repair
Heat pump owners in Blackheath can arrange a fault-finding visit at a rate agreed before an engineer attends.
Grants and rules for heat pumps in England
Homes in Blackheath 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 Blackheath: questions
Can you work on a heat pump in Blackheath that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Blackheath, whoever fitted them. Tell us the make and model when you get in touch.
How often should a heat pump in Blackheath 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 Lewisham?
Yes. We arrange heat pump servicing and repairs in Lewisham, which is about a mile south-west of Blackheath, and across Greater London.
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.
Is ice on my heat pump a fault?
Some frost on the outdoor unit in cold, damp weather is normal, and the unit clears it with regular defrost cycles, often releasing a little vapour. It becomes a fault when thick ice builds up and does not clear, or when ice blocks the fan. That can point to poor airflow, a failed sensor, drainage problems or low refrigerant, and needs checking.
