About our air source heat pumps in Dunsfold
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home, so an add-on next to a boiler is not eligible. We’re often asked to deal with checking whether planning permission is needed and wanting to stop using oil, LPG or gas for heating, across radiator systems, hot water cylinders and homes heated by oil, LPG or gas.
Homes around Dunsfold typically have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

What affects the cost of air source heat pumps
You’ll get a fixed price before work begins. It takes into account:
- Whether it’s a one-off job or part of a maintenance contract
- The condition of any existing system
- The brand, model and parts involved
Typical ranges are on our prices page, but each job is priced on what it involves. For a fixed-price quote, ring us on 07833 053749, and we will talk you through it.
What we need to know
Before you ask for a quote, gather:
- A close-up of the unit’s label showing the model number
- A few photos of the room and the wall the unit is on, or will go on
- Any error code or flashing light on the display
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price so you know the cost before we begin.
Common questions in Dunsfold
Will a heat pump in Dunsfold need planning permission?
It depends on the property. Central Dunsfold is a short walk from the Dunsfold Conservation Area. 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 Waverley council, which is usually the planning authority for Dunsfold first.
Does the Boiler Upgrade Scheme cover homes in Dunsfold?
Yes, if the home and the heat pump meet the scheme’s rules: Dunsfold is in England, where it applies. 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. As an MCS certified installer, we apply for it on your behalf.
Do you work in Dunsfold?
Yes. Our area takes in London and the counties of the South East, Dunsfold included.
When will I hear back?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
What happens if it’s left?
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water works with radiators and a cylinder, with a £7,500 grant for eligible homes, while air-to-air heats and cools rooms and has a £2,500 grant only in limited cases. We explain which makes sense for you. Planning ahead for a job in Dunsfold means we can bring everything needed.
What you pay reflects the actual work. That’s why we look at the job first, from pictures or on a survey, and the price is agreed before work begins.

When to call us in Dunsfold
People also ask about air-to-air heat pumps because they heat and cool. They heat rooms through wall, floor or ceiling units, and can cool them when it’s hot. The grant only applies in some cases, so we check first.
These are the situations we see most often:
- Deciding which kind of heat pump suits the home
- Planning and permitted development questions
- Questions about the Boiler Upgrade Scheme
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.
Before booking anyone
- Whose warranty applies, and on what terms
- How VAT is shown, and which rate applies
- If the quote is based on a survey, pictures or a diagnosis
How the visit works
Where something has to be switched off during the work, we agree it with you first so it doesn’t catch you out. In a business, work can often be done one area at a time. The work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. For a place like Dunsfold, the timing is set with you and the travel is our side of the planning.
- First, a chat about the property and your goals for the heating.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We explain which type of heat pump suits the home and whether a grant could apply.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Before we arrive
- Keep pets and children away from the work area
- Find the manual or the paperwork for the system, if you have it
- Make sure we can reach the outdoor unit, or where it will go
