Air source heat pumps for homes and businesses in East Wittering
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 the installer makes the application. Not every home qualifies, so we check eligibility before you commit. Common call-outs are for comparing heat pump types and working out where a cylinder could go, on radiator systems, air-to-water heat pumps and air-to-air heat pumps.
Cottages and older homes near East Wittering can lose heat faster, which a heat loss calculation will show. Sometimes insulation first is the better investment.
Each manufacturer sets its own warranty period. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

Common questions in East Wittering
Is the coast a problem for outdoor units in East Wittering?
It can. East Wittering is within about 1 mile 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.
Can I get the Boiler Upgrade Scheme grant in East Wittering?
Yes, the scheme covers homes in England, including East Wittering, if they qualify. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You don’t apply yourself: the MCS certified installer does, which is us.
Is there a survey before the work?
Yes. We always look before we price, on a survey, or from your photos and details where the job is simple. A fixed-price quote follows.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
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 work for landlords and businesses?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in East Wittering and across West Sussex. Let us know who the records should go to.
How long does a heat pump installation take?
An installation 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. We confirm the timing after the survey, and you can ring 07833 053749 or use the quote form to book it.
Signs you need air source heat pumps in East Wittering
Extensions, renovations and loft conversions are a natural time to rethink the heating. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.
These are the situations we see most often:
- Planning and permitted development questions
- Choosing between air-to-water and air-to-air
- A boiler that is getting old
A heat loss calculation decides the size of heat pump your home needs.
What to look for in a quote
- Which brand and model they’re proposing, and why
- Exactly what the price includes, from supply and fitting to commissioning
- How VAT is shown, and which rate applies
Aftercare tips
So the system stays in good health:
- Look at insulation alongside the heat pump
- File the MCS certificate safely
- Read the manufacturer’s warranty terms for your brand
The warranty on the heat pump is the manufacturer’s, on its own terms. We go through the conditions with you, including any servicing they ask for.
Keep the outdoor unit clear of leaves, plants and stored items. Airflow is what it runs on so keep it unobstructed.
What we do, step by step
The first job on site is protection: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. 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, and we clear up before we go. In a place like East Wittering, parking is rarely an issue, but tell us about gates and access to the back of the property.
- First we talk through the property and the current system.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Unlock any gate, garage or side passage we need
- Let us know where the consumer unit is
- Tell us about any building rules, permits or sign-in
Getting a price
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. After that, we send a fixed price before any work starts.

Air source heat pumps in East Wittering: the local picture
At about 1 mile from the coast, East Wittering is close enough for sea air to matter. Near the coast, we choose the outdoor unit position with salt-laden wind in mind. About 3 listed entries lie within half a mile of central East Wittering, Church of the Assumption of St Mary the Virgin (grade II*) among them. 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 usually handles East Wittering where necessary. The last census (2021) found about 77% of households in detached or semi-detached houses. Houses normally have space for an outdoor unit and a hot water cylinder.
Older homes near St Anne may need extra checks for planning and heat loss before a heat pump is designed.
