Every repair starts with a fault-finding visit, which is charged at a rate agreed before we attend. The guide price for a fault-finding visit is £90–£180 for the first hour, including VAT. The engineer reads the error history, tests the system and tells you what has failed, what the repair involves and what it will cost before any further work is done. If a part has to be ordered, you are told the likely wait and the price before you decide.
Across South Yorkshire and South Yorkshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer. For repeated faults in South Yorkshire, the engineer looks at the system design as well as the failed part. Heat pump owners in South Yorkshire can arrange a fault-finding visit at a rate agreed before an engineer attends.

Grants and rules for heat pumps in England
Homes in South Yorkshire can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.

Heat pump repairs questions
How much does a heat pump repair cost?
Heat pump repairs have a typical range of £90–£1,100, including VAT, depending on the part and labour involved. Sensor replacements sit at the lower end, while control boards and refrigerant repairs on split systems sit higher. Every repair starts with a fault-finding visit, with a guide price of £90–£180 for the first hour, and the repair is priced before work goes ahead.
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.
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.
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.
