Heat pump repairs in Sandwich: what to expect
Aftercare matters as much as installation. For a heat pump in Sandwich 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.
Repairs in Sandwich that need a part ordered are explained and priced before the engineer leaves. For repeated faults in Sandwich, 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
- 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
- Fault-finding visit at a rate agreed before attending
- A clear explanation of the fault and a price for the repair before work goes ahead
- Testing of sensors, pumps, valves, pressures and electrics
- System refill, venting and recommissioning after the repair
Across Sandwich and Kent, refrigerant repairs on split systems are carried out by an F-gas certified engineer.
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 Sandwich quote.

Designing for Sandwich's winters
On the shortest day Sandwich gets about 7 hours 52 minutes of daylight, and the winter sun reaches only around 15° 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.

- Tell us the make if you know it, the error code or symptoms, and send photos of the unit and controller.
- We confirm the fault-finding rate and arrange a visit in Sandwich.
- The engineer diagnoses the fault and gives you a written price for the repair.

Heat pump repairs in Sandwich: questions
Can you work on a heat pump in Sandwich that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Sandwich, whoever fitted them. Tell us the make and model when you get in touch.
Do you also cover Deal?
Yes. We arrange heat pump servicing and repairs in Deal, which is about 4 miles south-east of Sandwich, and across Kent.
How often should a heat pump in Sandwich 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.
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.
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.
