Air source heat pumps in Knightwood, done properly
Many air source heat pumps can be installed as permitted development in England, without a planning application. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. If you’re dealing with moving away from fossil-fuel heating and an oil, LPG or gas boiler near the end of its life, we can sort it out.
For a house near Knightwood, space outside is rarely the problem, so heat loss, radiators and the electrics are what we check.
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.

What a heat pump looks like in Knightwood
The 2021 Census found about 81% 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. Knightwood is about 67 miles from central London, well within the area we cover from our base in East Grinstead.
Historic houses such as South Stoneham House, about 3.7 miles south, are a reminder that listed homes need consent before a heat pump goes in. Live in one of the older houses around St Francis? Expect the survey to look closely at heat loss and at the building’s planning status.
Knightwood is about 1 mile west of Chandler's Ford, in Hampshire. We cover Knightwood for air source heat pumps, along with the rest of Hampshire. Count every place we list in Hampshire and you reach 683, with Knightwood on the list. For properties nearby, see our Guildford page (40 miles or so).
Postcode districts we cover here: SO53 and SO52. That includes properties on Foyle Road, Harvest Road and Flexford Road and the roads around them. If you’re just outside Knightwood, we cover Chilworth Old Village (2 miles south-west), Chilworth (2 miles south), North Baddesley (2 miles west), Toothill (3 miles south-west) and Bassett (3 miles south).

Around Knightwood
Typical jobs here are in properties near Toynbee School. For rail, the closest station is Chandlers Ford station, about 0.8 miles south-east. A little further out are Romsey Community Hospital (3.5 miles west) and Eastleigh Museum (2.5 miles south-east). For a walk, there’s Flexford Nature Reserve.
What owners can safely do
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Aftercare tips
Once we have finished, these simple steps help:
- Clear leaves and debris from the outdoor unit
- Diary the next service
- Keep up with insulation and draught-proofing
Should you have questions after the install, phone 07833 053749 or send an email and we will talk it through. Annual servicing helps keep the system working well.
A well-insulated home helps a heat pump, as lower heat loss means the system has less to do.
What we do, step by step
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. On site, 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. A few photos let us plan a visit to a place like Knightwood.
- It begins with your house and the heating it relies on now.
- Every room’s heat loss is worked out on site.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- Cost, grant and VAT appear on one fixed-price quote.
- Installation, commissioning and MCS registration complete the job.
How to prepare
- Find the manual or the paperwork for the system, if you have it
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Tell us about access, such as roof hatches, high walls or locked plant areas
Getting a quote
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
Advice
Leave it or put it right?
The extra £1,500 for homes heated by oil or LPG with no mains gas is available until March 2027. For homes that qualify, that is a reason to look into it now. Getting the date in early helps for a job in a place like Knightwood.
No two properties are the same, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all make a difference.

Your questions about air source heat pumps in Knightwood
Is Knightwood in your area for air source heat pumps?
Yes, Knightwood is within the area we cover. Just phone us on 07833 053749 or drop us a line with a few details.
Will you come out to Knightwood?
Yes. Knightwood 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.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before work begins, and the area is kept tidy throughout. At the end, we clear up and show you what we have done.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before booking anyone and we will gladly show you ours.
Who is responsible for leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. We install both types.
What a customer said
“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.”
