Your questions about air source heat pumps in Walliswood
Will a heat pump in Walliswood need planning permission?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Walliswood holds about 10 listed buildings and structures. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the local planning authority (for Walliswood, usually Mole Valley council) first.
Will you come out to Walliswood?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Do I need to service the system to keep the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we will tell you what your brand asks for.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water and the survey helps decide.
Do you survey before quoting?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
How soon will you get back to me?
We reply to enquiries the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
How we handle air source heat pumps in Walliswood
As an MCS certified installer, we fit air source heat pumps for homes in Walliswood and the rest of Surrey. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We help you work out which suits your home. If the problem is deciding which kind of heat pump suits the home and finding a place for the outdoor unit, we can sort it out.
Space for an outdoor unit is rarely an issue near Walliswood, so the design comes down to heat loss, radiators and hot water.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

How it works
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes a few days for most air-to-water installations, with air-to-air systems often quicker, and we clear up before we go. Pictures of the space and where the outdoor unit could go let us plan the work in Walliswood.
- First we find out about the property, the heating you have now and what you’re 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.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Arrange for someone to be there to let us in
- Keep pets and children away from the work area
- Move furniture away from the wall where we’ll be working
How to get a quote
Every quote shows the VAT clearly, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. To get one, phone 07833 053749 or write to us at info@aircondoctor.co.uk.

Air source heat pumps in Walliswood: the local picture
About 40% of homes in and around Walliswood were built before 1919, according to VOA council tax data, and about 76% of households live in detached or semi-detached houses, according to the 2021 Census. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. Houses usually have space for an outdoor unit and a hot water cylinder.
If your home is one of the older properties near Church of St John the Baptist, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Every heat pump design starts with a room-by-room heat loss calculation.
Walliswood is about 6 miles north-west of Horsham, in Surrey. Properties in Walliswood get the same service as everywhere we cover: diagnosis first, a fixed price and proper paperwork when we have finished. In Surrey alone we list 395 places and Walliswood is among them. You can also see our page for Horsham, about 6 miles away.
Our nearest recent job to Walliswood was on High Street, Cranleigh (GU6), about 4 miles west: installing two Daikin wall-mounted units in the main working hall and a third unit in the meeting room.
From Horsham Road, Standon Lane and Oakfields to the smaller roads in between, nowhere is left out. Work in RH5 follows the same survey, fixed-price quote and written records as everywhere else we cover. Close to Walliswood, our area also takes in Mayes Green (1 mile north), Ewhurst Green (2 miles north-west), Ellen's Green (2 miles south-west), Ewhurst (2 miles north-west) and Cranleigh (4 miles west).

For landlords and property managers
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
Whether it’s one property or many, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.

Leave it or put it right?
The two types suit different homes and needs.

Booking before summer means the work in Walliswood is done before the hot weather.
