What to know about heat pump repairs in Bonnyrigg
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 Bonnyrigg can arrange a fault-finding visit at a rate agreed before an engineer attends. Repairs in Bonnyrigg 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.
- Heat pumps showing an error code or fault light
- Rooms or hot water not getting warm enough
- Heat pumps installed by another company that need a second opinion
What's included
- Fault-finding visit at a rate agreed before attending
- Supply and fitting of replacement parts
- Reading of error history and operating data
- System refill, venting and recommissioning after the repair
- Refrigerant repairs by an F-gas certified engineer where needed
Outdoor units in exposed spots around Bonnyrigg can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in Scotland
The Boiler Upgrade Scheme does not apply in Scotland. Instead, homeowners in Bonnyrigg 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.

Heat pump repairs in Bonnyrigg: questions
Can you work on a heat pump in Bonnyrigg that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Bonnyrigg, whoever fitted them. Tell us the make and model when you get in touch.
Do you also cover Dalkeith?
Yes. We arrange heat pump servicing and repairs in Dalkeith, which is about 2 miles north-east of Bonnyrigg, and across Edinburgh and the Lothians.
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.
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.
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.
