Heat pump repairs for Salisbury homes
Aftercare matters as much as installation. For a heat pump in Salisbury 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.
Across Salisbury and Wiltshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer. Repairs in Salisbury 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 showing an error code or fault light
What's included
- Reading of error history and operating data
- 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
- Supply and fitting of replacement parts
- System refill, venting and recommissioning after the repair
We repair heat pumps in Salisbury whoever installed them, including older monobloc and split systems.
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 Salisbury quote.

Heat pump repairs in Salisbury: 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.
Can you work on a heat pump in Salisbury that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Salisbury, whoever fitted them. Tell us the make and model when you get in touch.
How often should a heat pump in Salisbury 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.
Can you repair a heat pump installed by another company?
Yes. We carry out fault-finding and repairs on heat pumps installed by other companies, including monobloc and split systems. Tell us the make, model and approximate age when you get in touch, plus any error code shown. If the system is still under the manufacturer's warranty, it may be quicker to contact the original installer or manufacturer first.
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.
