About our air source heat pumps in North Mundham
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. The work covers air-to-air heat pumps, hot water cylinders and underfloor heating, and the jobs we see most are ageing boilers that will need replacing and wanting to stop using oil, LPG or gas for heating.
If your home in or near North Mundham is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval.

On site, it takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. Visits to North Mundham are agreed with you in advance and planned so the job can be finished in one trip where possible.

Air source heat pumps around North Mundham
The coast is only about 3 miles from North Mundham. For a heat pump near the sea, ask about any coastal protection option the manufacturer offers. Historic England lists about 13 buildings and structures within half a mile of the centre of North Mundham, including Mundham House and Fernden (grade II*). For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with the planning team at Chichester council, which typically handles North Mundham where needed. Valuation Office Agency council tax records show about 34% of homes across North Mundham and its surrounding area were built in 2000 or later. Better insulated, newer homes are often a good match for a heat pump.
With Goodwood House about 4 miles north, it’s worth asking whether your own home is listed before planning a heat pump. If your home is one of the older properties near The Parish Church of St Stephen, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

North Mundham: your questions answered
Will you come out to North Mundham?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Does being near the sea make a difference to air source heat pumps in North Mundham?
It can. North Mundham is within about 3 miles of the coast, and salt air speeds up corrosion on outdoor units. We site outdoor units out of the worst of the sea wind where possible and can suggest models with corrosion protection where the manufacturer offers it.
Which accreditations do you hold?
As the law requires for refrigerant work, we are an F-Gas certified company. We are also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before any work starts, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Do I need new radiators for a heat pump?
Some radiators may be fine as they are, and some may need to be larger. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Do you provide F-Gas records?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Do you offer emergency call-outs?
Yes. Our emergency line runs 24/7 for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
Why it’s worth doing now in North Mundham
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases. We explain which makes sense for you. Dealing with it now is usually simpler than a breakdown later.
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are not sure what’s needed, ring 07833 053749 or fill in the contact form for straight advice and a fixed price.
