Before you book: heat pump repairs in Poole
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 Poole can arrange a fault-finding visit at a rate agreed before an engineer attends. For repeated faults in Poole, 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.
- Heat pumps showing an error code or fault light
- Heat pumps installed by another company that need a second opinion
- Rooms or hot water not getting warm enough
What's included
- Reading of error history and operating data
- Fault-finding visit at a rate agreed before attending
- Supply and fitting of replacement parts
- Refrigerant repairs by an F-gas certified engineer where needed
- System refill, venting and recommissioning after the repair
Outdoor units in exposed spots around Poole can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Poole quote.

Short winter days in Poole and what they mean
On the shortest day Poole gets about 7 hours 57 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

- We confirm the fault-finding rate and arrange a visit in Poole.
- The engineer diagnoses the fault and gives you a written price for the repair.
- Parts are ordered once you agree, and the repair is completed and tested.
Heat pump repairs in Poole: questions
Can you work on a heat pump in Poole that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Poole, whoever fitted them. Tell us the make and model when you get in touch.
What should I check before booking a visit in Poole?
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 Bournemouth?
Yes. We arrange heat pump servicing and repairs in Bournemouth, which is about 5 miles east of Poole, and across Dorset.
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.
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.
