Air source heat pumps in South Mundham, done properly
Every installation starts with a heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. If the problem is working out where a cylinder could go and wanting to stop using oil, LPG or gas for heating, we can sort it out.
Homes around South Mundham typically have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. If a lane or gateway near South Mundham is tight for a van, let us know and we will plan for it.
- First, a chat about the property and your goals for the heating.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We explain which type of heat pump suits the home and whether a grant could apply.
- The system is installed and connected to the controls.

Common questions in South Mundham
Do you cover smaller places like South Mundham?
Yes. South Mundham is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.
Does being near the sea make a difference to air source heat pumps in South Mundham?
It can. South Mundham is within about 2 miles of the coast, and salt air speeds up corrosion on outdoor units. The outdoor unit position, its fixings and regular servicing all help near the sea.
Do you work on all makes?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Should I choose air-to-water or air-to-air?
The right choice depends on the property and what you need. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases, and we set out the options after the survey.
When will I hear back?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll agree what happens next.
Do I need to service the system to keep the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we will tell you what your brand asks for.
Honest limits
Not every problem is solved by air source heat pumps, and we will tell you before any work starts. It doesn’t solve:
- Grants for hybrid systems or replacements of low-carbon systems
- Disconnecting or servicing a gas boiler
- Tax advice on your own circumstances
If you’re not sure, just call us on 07833 053749 or fill in the contact form and we will give you a straight answer.
Parts of the system we cover
- Underfloor heating
- Homes heated by oil, LPG or gas
- Air-to-air heat pumps
- Hot water cylinders
- Air-to-water heat pumps
- Radiator systems
Leave it or put it right?
Radiators that are too small for a heat pump’s lower flow temperature leave rooms cool. The survey picks this up before installation. A system that is left with a fault, or without a service, usually costs more to run.
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed price.

Air source heat pumps in South Mundham: the local picture
The coast is only about 2 miles from South Mundham. Near the coast, we choose the outdoor unit position with salt-laden wind in mind. Listed buildings are part of the picture here: about 5 within half a mile of the centre, such as South Mundham Farmhouse (grade II*). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area? Valuation Office Agency council tax records date about 56% of homes in the South Mundham area to the post-war years, 1945 to 1972, and about 72% of households live in detached or semi-detached houses, according to the 2021 Census. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder.
Older homes near The Parish Church of St Stephen may need extra checks for planning and heat loss before a heat pump is designed.
