Heat pump repairs in Lanark: what to expect
Aftercare matters as much as installation. For a heat pump in Lanark the visit checks the outdoor unit, the water circuit and the controls, and the engineer explains any settings that would help the system run more efficiently.
We repair heat pumps in Lanark whoever installed them, including older monobloc and split systems. For repeated faults in Lanark, the engineer looks at the system design as well as the failed part.
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.
- Systems losing pressure or needing frequent topping up
- Rooms or hot water not getting warm enough
- Heat pumps showing an error code or fault light
What's included
- Reading of error history and operating data
- A clear explanation of the fault and a price for the repair before work goes ahead
- System refill, venting and recommissioning after the repair
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
Across Lanark and Lanarkshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a Lanark home, apply and receive the written offer before the installation date is fixed.

Heat pump repairs in Lanark: questions
How often should a heat pump in Lanark 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 Carluke?
Yes. We arrange heat pump servicing and repairs in Carluke, which is about 5 miles north-west of Lanark, and across Lanarkshire.
Can you work on a heat pump in Lanark that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Lanark, whoever fitted them. Tell us the make and model when you get in touch.
Why does my heat pump keep switching on and off?
Frequent starting and stopping, called short cycling, is usually caused by an oversized heat pump, low water flow, too many zones closing at once or controls set with too narrow a range. It reduces efficiency and wears components. An engineer can check the settings, flow rates and design, and can often improve it with control changes before any parts are needed.
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.
