Before you book: heat pump repairs in Knighton
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 Knighton can arrange a fault-finding visit at a rate agreed before an engineer attends. We repair heat pumps in Knighton whoever installed them, including older monobloc and split systems.
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
- 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
- Reading of error history and operating data
- System refill, venting and recommissioning after the repair
For repeated faults in Knighton, the engineer looks at the system design as well as the failed part.
Grants and rules for heat pumps in Wales
In Wales 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; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Knighton quote.

Heat pump repairs in Knighton: questions
Can you work on a heat pump in Knighton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Knighton, whoever fitted them. Tell us the make and model when you get in touch.
Do you also cover Newtown?
Yes. We arrange heat pump servicing and repairs in Newtown, which is about 16 miles north-west of Knighton, and across Powys.
What should I check before booking a visit in Knighton?
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.
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.
