What to know about heat pump repairs in Lerwick
Whoever installed your heat pump, aftercare can be arranged in Lerwick. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Outdoor units in exposed spots around Lerwick can ice more heavily, so siting is checked as part of any icing fault. Repairs in Lerwick that need a part ordered are explained and priced before the engineer leaves.
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.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Systems losing pressure or needing frequent topping up
- Heat pumps installed by another company that need a second opinion
What's included
- Testing of sensors, pumps, valves, pressures and electrics
- Refrigerant repairs by an F-gas certified engineer where needed
- A clear explanation of the fault and a price for the repair before work goes ahead
- Fault-finding visit at a rate agreed before attending
- Supply and fitting of replacement parts
Heat pump owners in Lerwick can arrange a fault-finding visit at a rate agreed before an engineer attends.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Lerwick can apply to Home Energy Scotland for a grant of up to £7,500 towards a heat pump, with up to £1,500 more for eligible rural and island homes, plus an optional interest-free loan of up to £7,500. You need a written funding offer before any work starts.

Winter daylight and heating in Lerwick
On the shortest day Lerwick gets only about 5 hours 49 minutes of daylight, with the sun around 6° 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 Lerwick: questions
What should I check before booking a visit in Lerwick?
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.
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.
How often should a heat pump in Lerwick 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.
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.
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.
