Before you book: heat pump repairs in Chichester
Whoever installed your heat pump, aftercare can be arranged in Chichester. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Across Chichester and West Sussex, refrigerant repairs on split systems are carried out by an F-gas certified engineer. Outdoor units in exposed spots around Chichester can ice more heavily, so siting is checked as part of any icing fault.
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
- Outdoor units that have become noisy, iced up or keep switching on and off
- Systems losing pressure or needing frequent topping up
What's included
- System refill, venting and recommissioning after the repair
- 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
- Testing of sensors, pumps, valves, pressures and electrics
- Reading of error history and operating data
We repair heat pumps in Chichester whoever installed them, including older monobloc and split systems.
Grants and rules for heat pumps in England
Homes in Chichester 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.

Short winter days in Chichester and what they mean
On the shortest day Chichester gets about 7 hours 56 minutes of daylight, and the winter sun reaches only around 16° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.

- We confirm the fault-finding rate and arrange a visit in Chichester.
- The engineer diagnoses the fault and gives you a written price for the repair.

Heat pump repairs in Chichester: 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.
What should I check before booking a visit in Chichester?
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 Chichester that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Chichester, whoever fitted them. Tell us the make and model when you get in touch.
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.
Is ice on my heat pump a fault?
Some frost on the outdoor unit in cold, damp weather is normal, and the unit clears it with regular defrost cycles, often releasing a little vapour. It becomes a fault when thick ice builds up and does not clear, or when ice blocks the fan. That can point to poor airflow, a failed sensor, drainage problems or low refrigerant, and needs checking.
