Before you book: heat pump repairs in East Grinstead
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.
Across East Grinstead and West Sussex, refrigerant repairs on split systems are carried out by an F-gas certified engineer. Repairs in East Grinstead 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.
- Rooms or hot water not getting warm enough
- Systems losing pressure or needing frequent topping up
- Outdoor units that have become noisy, iced up or keep switching on and off
What's included
- System refill, venting and recommissioning after the repair
- Testing of sensors, pumps, valves, pressures and electrics
- Supply and fitting of replacement parts
- Refrigerant repairs by an F-gas certified engineer where needed
- Fault-finding visit at a rate agreed before attending
We repair heat pumps in East Grinstead whoever installed them, including older monobloc and split systems.
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 East Grinstead quote.
