Air source heat pumps in Blackstone
A £2,500 grant is available for some air-to-air heat pumps, with conditions. 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; adding it alongside a boiler does not qualify. If you are dealing with working out where a cylinder could go and radiators that may be too small for a heat pump, we can sort it out.
In a place like Blackstone, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so we check consent first.
Warranty periods vary by brand and by product. Daikin, for instance, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Blackstone: your questions answered
Will you come out to Blackstone?
Yes, smaller places are covered as well as towns. Send a few details and pictures, and we reply the same working day.
Does the Boiler Upgrade Scheme cover homes in Blackstone?
Blackstone is in England, where the Boiler Upgrade Scheme runs. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
How quickly will you reply?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
How much does an air source heat pump cost?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
How the job changes from property to property
VAT on heat pumps
Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5% following HMRC’s rules on energy-saving materials. It doesn’t apply to businesses.
Hot water cylinders
An older cylinder may not suit a heat pump, and we explain whether yours can stay.
What you can do yourself, and what needs us
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
For landlords and property managers
From a single flat to a whole estate, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.

What else we do in Blackstone
Air source heat pumps around Blackstone
The centre of Blackstone lies within the Blackstone Conservation Area. Historic England lists about 7 buildings and structures within half a mile of the centre of Blackstone, including Corner Cottages (grade II). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area? The last census (2021) found about 70% of households in detached or semi-detached houses. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
A heat loss calculation decides the size of heat pump your home needs. Live in one of the older houses around The Parish Church of St Bartholomew? Expect the survey to look closely at heat loss and at the building’s planning status.
Blackstone is about 5 miles west of Burgess Hill, in West Sussex. Our engineers cover Blackstone for air source heat pumps and across the rest of West Sussex. Our West Sussex coverage runs to 371 places, Blackstone among them.

How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. Somewhere like Blackstone, it helps to know about lanes, gates and where to park.
- 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 recommend air-to-water or air-to-air and check the grant position.
- Installation follows on the agreed dates.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Getting ready for the visit
- Clear a path to the units and the space around them
- Make sure someone can let us in at the agreed time
- Make sure we can reach the consumer unit or fuse board
