Before you book: heat pump repairs in Witham
Whoever installed your heat pump, aftercare can be arranged in Witham. 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 pump owners in Witham can arrange a fault-finding visit at a rate agreed before an engineer attends. We repair heat pumps in Witham 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
- 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
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Testing of sensors, pumps, valves, pressures and electrics
- Supply and fitting of replacement parts
- Reading of error history and operating data
- Fault-finding visit at a rate agreed before attending
For repeated faults in Witham, the engineer looks at the system design as well as the failed part.
Grants and rules for heat pumps in England
Homes in Witham 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.

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.
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.
