Air source heat pumps for homes and businesses in Merstone
In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. We’re often asked to deal with checking eligibility for a heat pump grant and an oil, LPG or gas boiler near the end of its life, on air-to-water heat pumps, underfloor heating and hot water cylinders.
In a place like Merstone, some homes are listed, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

What affects the cost of air source heat pumps
The quote reflects the job in front of us. We take into account:
- How easy the units are to reach
- What state the existing equipment is in
- The number of rooms, units or zones
Typical ranges are on our prices page, but your price depends on the job in front of us. Call for a fixed-price quote, and we will explain what it covers.
Before you get in touch
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- The rating plate or label on any existing unit
- The postcode and whether it’s a home, flat or business
- A few photos of the room and the wall the unit is on, or will go on

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 we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which 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. Pictures of the space and where the outdoor unit could go let us plan the work in Merstone.
- First we find out about the property, the heating you have now and what you are hoping for.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Installation covers the outdoor unit, the indoor connections and the controls.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Preparing for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Move furniture away from the wall where we will be working
- Mention any roof access, ladders or high-level work

VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it on the quote. To get one, call us on 07833 053749 or write to us at info@aircondoctor.co.uk.

Merstone: your questions answered
Will you come out to Merstone?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I get the Boiler Upgrade Scheme grant in Merstone?
Yes, the scheme covers homes in England, including Merstone, if they qualify. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. We hold MCS certification, so the application is ours to make for you.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
Will my radiators work with a heat pump?
We find out during the survey. Rooms where the radiator is big enough stay as they are and any changes are in the quote.
When will I hear back?
On the same working day you contact us. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Do you offer emergency call-outs?
Yes. There’s a 24/7 emergency line for problems that can’t wait for a planned visit. Ring 07833 053749 any time and explain the problem.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.

Homes in Merstone and heat pumps
The middle of Merstone is part of a conservation area. About 4 listed entries lie within half a mile of central Merstone, Merston Manor (grade II*) among them. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where necessary, we check with Isle of Wight council, usually the planning authority here. The last census (2021) found about 66% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Every heat pump design starts with a room-by-room heat loss calculation. Historic houses such as Arreton Manor, about 1.1 miles north, are a reminder that listed homes need consent before a heat pump goes in.
Merstone is about 3 miles south-east of Newport, in the Isle of Wight. Across the PO30 area, we can help with air source heat pumps. Across the Isle of Wight, we cover 125 places, and Merstone is one of them. We also work in Worthing, about 39 miles from Merstone.

Nearby, we also cover air source heat pumps in Arreton (1 mile north-east), Rookley (1 mile south-west), Hale Common (1 mile south-east), Rookley Green (1 mile south-west) and Blackwater (2 miles north-west). We also work in nearby towns such as Newport (3 miles north-west), Ryde (6 miles north-east), Cowes (7 miles north) and Sandown (4 miles east). If your property is somewhere remote, a little more planning is needed, so mention it when you ask for a quote.

Aftercare tips
Aftercare is straightforward, and it helps at the next service:
- Keep to regular servicing
- Keep the MCS certificate with the manufacturer’s paperwork
- Leave indoor units unobstructed
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Don’t cover radiators with furniture or heavy curtains so the heat can get into the room.
