Before you book: heat pump repairs in Liverpool
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.
Heat pump owners in Liverpool can arrange a fault-finding visit at a rate agreed before an engineer attends. We repair heat pumps in Liverpool 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.
- Heat pumps showing an error code or fault light
- Systems losing pressure or needing frequent topping up
- Outdoor units that have become noisy, iced up or keep switching on and off
What's included
- 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
- Refrigerant repairs by an F-gas certified engineer where needed
- Supply and fitting of replacement parts
Repairs in Liverpool that need a part ordered are explained and priced before the engineer leaves.
Grants and rules for heat pumps in England
Homes in Liverpool 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 Liverpool: questions
Do you also cover Birkenhead?
Yes. We arrange heat pump servicing and repairs in Birkenhead, which is about 2 miles south-west of Liverpool, and across Merseyside.
How often should a heat pump in Liverpool 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.
Can you work on a heat pump in Liverpool that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Liverpool, whoever fitted them. Tell us the make and model when you get in touch.
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.
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.
