Southwick questions
Do you cover smaller places like Southwick?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Does the Boiler Upgrade Scheme cover homes in Southwick?
Yes, the scheme covers homes in England, including Southwick, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
How much does an air source heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme, and we confirm eligibility before you commit.
How long does a heat pump installation take?
It takes a few days on site, depending on the cylinder, the radiators and the pipework involved. How much of the heating changes decides most of the time and the timing is set out with your quote.
Do I need new radiators for a heat pump?
That depends on the room’s heat loss and the radiator’s size. The survey compares each radiator with the room’s needs and the quote shows what’s needed.
How quickly will you reply?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
How we handle air source heat pumps in Southwick
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home; adding it alongside a boiler doesn’t qualify. The work covers hot water cylinders, underfloor heating and radiator systems, and people most often call us about ageing boilers that will need replacing and questions about listed buildings or conservation areas.
Whether a home near Southwick has mains gas makes a difference to the grant. Homes heated by oil or LPG with no mains gas can get an extra £1,500 on the Boiler Upgrade Scheme until March 2027, for an air source or ground source heat pump.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order and each visit is recorded.

What we do, step by step
Think of the visit in three stages: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, which takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Send pictures of the space and the outside wall, and we can plan the work near Southwick.
- It starts with a conversation about the home, the existing heating and your plans.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Commissioning, MCS certification and a handover of the controls finish the job.
Preparing for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets out of the rooms we’re working in
- Tell us about parking and loading
Ask for a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price so you know the cost before we begin.

Homes in Southwick and heat pumps
Southwick is within about 1 mile of the coast. Salt air is hard on outdoor units, so a heat pump near the sea needs a sensible position and regular checks, and some models offer corrosion protection for coastal sites. Valuation Office Agency council tax records date about 41% of homes in the Southwick area to the post-war years, 1945 to 1972. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. The middle of Southwick is part of the Southwick Conservation Area. 2 conservation areas lie within a mile of central Southwick. Historic England lists about 18 buildings and structures within half a mile of the centre of Southwick, including The Hall (grade II*). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
If your home is near Southwick station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.

When to call us in Southwick
The Boiler Upgrade Scheme has made people ask whether their home could qualify. Eligibility depends on the property, the system and the scheme rules, so we check before you commit.
It’s time to call us if you’re dealing with:
- Not knowing whether a grant applies
- Deciding which kind of heat pump suits the home
- No space for a hot water cylinder
If your home is one of the older properties near St Michael and All Angels Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
Before booking anyone
- Whether extra work needs your approval first
- The make and model of any parts or equipment being quoted
- What the manufacturer’s warranty covers and for how long
After we have gone
Looking after the system is mostly common sense. Our tips:
- Check eligibility for the Boiler Upgrade Scheme early
- Keep radiators clear
- Know the servicing conditions in your warranty
Equipment warranties come from the manufacturer. We go through the conditions with you, including any servicing they ask for.
Keep insulation and draught-proofing in good order, as lower heat loss means the system has less to do.
Before you call an engineer
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
