Heat pump repairs for Gravesend homes
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.
We repair heat pumps in Gravesend whoever installed them, including older monobloc and split systems. For repeated faults in Gravesend, 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 showing an error code or fault light
- 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
What's included
- Supply and fitting of replacement parts
- 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
- Reading of error history and operating data
Repairs in Gravesend that need a part ordered are explained and priced before the engineer leaves.
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 Gravesend quote.

Short winter days in Gravesend and what they mean
On the shortest day Gravesend gets about 7 hours 50 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.

Heat pump repairs in Gravesend: questions
How often should a heat pump in Gravesend 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.
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.
Can you work on a heat pump in Gravesend that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Gravesend, 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.
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.
