Heat pump repairs in Royston: what to expect
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.
Outdoor units in exposed spots around Royston can ice more heavily, so siting is checked as part of any icing fault. For repeated faults in Royston, 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 installed by another company that need a second opinion
- Rooms or hot water not getting warm enough
- Systems losing pressure or needing frequent topping up
What's included
- A clear explanation of the fault and a price for the repair before work goes ahead
- System refill, venting and recommissioning after the repair
- Fault-finding visit at a rate agreed before attending
- Reading of error history and operating data
- Supply and fitting of replacement parts
Repairs in Royston that need a part ordered are explained and priced before the engineer leaves.

Heat pump repairs in Royston: questions
How much does a visit cost in Royston?
The rate for a service or fault-finding visit is agreed before anyone attends. Any repair is priced in writing before parts are ordered, so you decide before work goes ahead.
What should I check before booking a visit in Royston?
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.
Can you work on a heat pump in Royston that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Royston, whoever fitted them. Tell us the make and model when you get in touch.
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.
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.
