Heat pump repairs in Larbert: what to expect
Aftercare matters as much as installation. For a heat pump in Larbert 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.
Repairs in Larbert that need a part ordered are explained and priced before the engineer leaves. Across Larbert and Stirling, Falkirk and Clackmannanshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
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.
- Rooms or hot water not getting warm enough
- Systems losing pressure or needing frequent topping up
- Heat pumps installed by another company that need a second opinion
What's included
- Refrigerant repairs by an F-gas certified engineer where needed
- Fault-finding visit at a rate agreed before attending
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
- Supply and fitting of replacement parts
We repair heat pumps in Larbert whoever installed them, including older monobloc and split systems.
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 Larbert home, apply and receive the written offer before the installation date is fixed.

Short winter days in Larbert and what they mean
On the shortest day Larbert gets only about 6 hours 56 minutes of daylight, with the sun around 11° up at noon. Long Scottish winters mean the heat pump runs for much of the year, so careful sizing, good controls and correctly sized radiators make a real difference.

Heat pump repairs in Larbert: questions
Will the engineer need access indoors as well as outside?
Usually yes. The outdoor unit, the hot water cylinder, the controls and the pipework and valves indoors are all part of the visit, so allow access to each.
What should I check before booking a visit in Larbert?
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.
Do you also cover Falkirk?
Yes. We arrange heat pump servicing and repairs in Falkirk, which is about 2 miles south-east of Larbert, and across Stirling, Falkirk and Clackmannanshire.
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.
Do refrigerant repairs need a specialist?
Yes. Any work on a heat pump's refrigerant circuit, such as tracing a leak, replacing a component or re-gassing, must by law be done by an F-gas certified engineer where the refrigerant is fluorinated, such as R32; units using R290 (propane) need an engineer trained in flammable refrigerants. On split systems the refrigerant runs through pipes inside your home, so leaks there are more likely than on sealed monobloc units.
