Before you book: heat pump repairs in Havant
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 Havant and Hampshire, refrigerant repairs on split systems are carried out by an F-gas certified engineer. We repair heat pumps in Havant whoever installed them, including older monobloc and split systems.
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
- Rooms or hot water not getting warm enough
- Outdoor units that have become noisy, iced up or keep switching on and off
What's included
- Reading of error history and operating data
- A clear explanation of the fault and a price for the repair before work goes ahead
- Refrigerant repairs by an F-gas certified engineer where needed
- System refill, venting and recommissioning after the repair
- Testing of sensors, pumps, valves, pressures and electrics
Heat pump owners in Havant can arrange a fault-finding visit at a rate agreed before an engineer attends.
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 Havant quote.

Short winter days in Havant and what they mean
On the shortest day Havant 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.
What happens when you book in Havant?
- 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 Havant.
- 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 Havant: questions
What should I check before booking a visit in Havant?
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 you also cover Waterlooville?
Yes. We arrange heat pump servicing and repairs in Waterlooville, which is about 3 miles north-west of Havant, and across Hampshire.
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.
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 does my heat pump keep switching on and off?
Frequent starting and stopping, called short cycling, is usually caused by an oversized heat pump, low water flow, too many zones closing at once or controls set with too narrow a range. It reduces efficiency and wears components. An engineer can check the settings, flow rates and design, and can often improve it with control changes before any parts are needed.
