What to know about heat pump repairs in Bicester
Whoever installed your heat pump, aftercare can be arranged in Bicester. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
We repair heat pumps in Bicester whoever installed them, including older monobloc and split systems. Repairs in Bicester 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.
- Systems losing pressure or needing frequent topping up
- Heat pumps installed by another company that need a second opinion
- Outdoor units that have become noisy, iced up or keep switching on and off
What's included
- 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
- Fault-finding visit at a rate agreed before attending
- Supply and fitting of replacement parts
- Testing of sensors, pumps, valves, pressures and electrics
Outdoor units in exposed spots around Bicester can ice more heavily, so siting is checked as part of any icing fault.
Grants and rules for heat pumps in England
Homes in Bicester 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 in Bicester: 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.
Do you also cover Oxford?
Yes. We arrange heat pump servicing and repairs in Oxford, which is about 11 miles south-west of Bicester, and across Oxfordshire.
What should I check before booking a visit in Bicester?
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 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.
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.
