How we handle air source heat pumps in Carterton
As an MCS certified installer, we fit air source heat pumps for homes in Carterton and the rest of Oxfordshire. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. Common call-outs are for questions about where the outdoor unit can go and a boiler that’s getting old, on hot water cylinders, radiator systems and air-to-water heat pumps.
In a town like Carterton, most heat pump enquiries are for houses heated by a gas boiler. A survey looks at heat loss, radiators, the hot water cylinder and where the outdoor unit can go, then design the system.
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.

What the work involves, system by system
Heat loss surveys
Without a proper survey, a heat pump can be too big or too small and that matters for comfort and running.
Outdoor unit position and planning
Under permitted development, the outdoor unit must be 1.5 m³ or less, compliance with MCS 020(a), and use for more than cooling alone. It cannot be within the curtilage of a listed building.
Pricing air source heat pumps in Carterton
Before we fix a price, we need to know a few things. We check:
- How many units are involved
- What electrical work the job needs
- The type of system, from a single split to a larger system
Several rooms, units or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
Helping us quote
To speed up the quote, please include:
- Any error code or flashing light on the display
- Where the outdoor unit is, or where you’d like it
- The postcode and whether it’s a home, flat or business
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. Then you get a fixed price so you know the cost before we begin.

How the visit works
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. 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. Shops and offices in Carterton can normally stay open while we work, or we come after hours.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Preparing for the visit
- Tell us about any building rules, permits or sign-in
- Keep pets and children away from the work area
- Have the make and model of any existing unit to hand

What happens if it’s left?
The 0% VAT rate on heat pumps in homes runs until 31 March 2027, then 5% applies. If you’re thinking about a heat pump, that date is worth knowing, though the right time also depends on your home and heating. A system that’s left with a fault, or without a service, usually costs more to run.
Homes, offices, shops and public buildings are all priced the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we’ll explain each part.

Questions from Carterton
Can I get the Boiler Upgrade Scheme grant in Carterton?
Carterton is covered, as the scheme runs across England and Wales. The amount depends on the type of heat pump, and the survey confirms which applies. As an MCS certified installer, we apply for it on your behalf.
What’s the best way to get a price for air source heat pumps in Carterton?
Start with a short message: the address, what you need and a picture or two. Where photos are not enough, a survey comes first and the fixed-price quote follows.
Will skipping a service affect the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Do you work in Carterton?
Yes. Our engineers work in Carterton, within the South East and London area we cover. We’re based in East Grinstead, West Sussex.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. At the end, we clear up and show you what we’ve done.
Why does F-Gas certification matter?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Homes in Carterton and heat pumps
About 35% of homes in Carterton and the neighbourhoods around it have been built since 2000, according to Valuation Office Agency council tax records, and the last census (2021) found about 65% of households in detached or semi-detached houses. Newer homes normally lose less heat, which tends to suit a heat pump well. Houses normally have space for an outdoor unit and a hot water cylinder. At about 67 miles from central London, Carterton sits inside the area we cover across London and the South East.
Minster Lovell Hall lies about 3.5 miles north-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions. Older homes near St John the Evangelist may need extra checks for planning and heat loss before a heat pump is designed.
