Before you book: heat pump repairs in Newhaven
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.
Heat pump owners in Newhaven can arrange a fault-finding visit at a rate agreed before an engineer attends. Repairs in Newhaven 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.
- Outdoor units that have become noisy, iced up or keep switching on and off
- Heat pumps installed by another company that need a second opinion
- Systems losing pressure or needing frequent topping up
What's included
- 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
- Refrigerant repairs by an F-gas certified engineer where needed
- System refill, venting and recommissioning after the repair
Across Newhaven and East Sussex, 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 Newhaven quote.

Winter daylight and heating in Newhaven
On the shortest day Newhaven gets about 7 hours 57 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 Newhaven.
- The engineer diagnoses the fault and gives you a written price for the repair.
- Parts are ordered once you agree, and the repair is completed and tested.
Heat pump repairs in Newhaven: questions
Do you also cover Seaford?
Yes. We arrange heat pump servicing and repairs in Seaford, which is about 3 miles south-east of Newhaven, and across East Sussex.
Can you work on a heat pump in Newhaven that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Newhaven, whoever fitted them. Tell us the make and model when you get in touch.
What should I check before booking a visit in Newhaven?
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.
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 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.
