Gay Street air source heat pumps
Expert air source heat pumps for Gay Street: diagnosis first, then a fixed-price quote, the work and written records. Ask us for a fixed-price quote.
- No space for a hot water cylinder
- Not knowing whether a grant applies
- Moving away from fossil-fuel heating
Let and managed properties
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork and we will copy in whoever needs it.
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
Air source heat pumps in Gay Street
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. The technology is close to air conditioning, which is why we install both and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. If the problem is deciding which kind of heat pump suits the home and wanting to stop using oil, LPG or gas for heating, we can help.
Space for an outdoor unit is rarely an issue near Gay Street, so the design focuses on heat loss and radiators.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

System by system
VAT on heat pumps
Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5% following HMRC’s rules on energy-saving materials. It doesn’t apply to businesses.
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, which is why radiator sizing is part of the survey.

What affects the quote in Gay Street
A fixed price needs a few facts first. We look at:
- What kind of system it is
- The electrical supply and whether a new circuit is needed
- How many units are involved
Every job is different, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all make a difference.

What we do, step by step
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work 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 Gay Street are agreed with you in advance and planned so the job can be finished in one trip where possible.
- 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 recommend air-to-water or air-to-air and check the grant position.
- We install the heat pump and connect it up.
- We commission it, complete the MCS certificate and show you how to use it.
Preparing for the visit
- Have the make and model of any existing unit to hand
- Make sure we can reach the outdoor unit, or where it will go
- Let us know where the consumer unit is

What a heat pump looks like in Gay Street
The 2021 Census found about 92% of households in detached or semi-detached houses. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder.
With Old Place Manor about 2.4 miles south-west, it’s worth asking whether your own home is listed before planning a heat pump. A heat loss calculation decides the size of heat pump your home needs.
Gay Street is about 9 miles south-west of Horsham, in West Sussex. Our engineers cover Gay Street for air source heat pumps and across the rest of West Sussex. In West Sussex alone we list 371 places and Gay Street is among them. You can also see our page for Horsham, about 9 miles away.
The closest recent job we can point to from Gay Street was on Lower Street, Pulborough (RH20), about 2 miles south-west: installing a Daikin multi-split system serving the restaurant dining area, the private function room and the bar area as part of a major refurbishment programme.

Gay Street: your questions answered
Is planning permission needed for a heat pump in Gay Street?
It depends on the property. The half-mile around the middle of Gay Street holds about 7 listed buildings and structures. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Gay Street, normally Horsham council).
Will you come out to Gay Street?
Yes. Gay Street is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Which type of heat pump is right for my home?
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.
How quickly will you reply?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
What’s the price of a heat pump installation?
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 though not every home qualifies.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.

“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.”
