Air source heat pumps for homes and businesses in New Denham
For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales and the installer makes the application. Not every home qualifies, so we check eligibility before you commit. We are often asked to deal with checking whether planning permission is needed and no space for a hot water cylinder, on air-to-air heat pumps, underfloor heating and homes heated by oil, LPG or gas.
For a home around New Denham that’s off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

New Denham: your questions answered
Is the heat pump grant available in New Denham?
Yes, if the home and the heat pump meet the scheme’s rules: New Denham is in England, where it applies. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You don’t apply yourself: the MCS certified installer does, which is us.
Do you cover smaller places like New Denham?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can you set up regular servicing?
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.
Do I need new radiators for a heat pump?
The heat loss survey answers that, room by room. Rooms where the radiator is big enough stay as they are and any changes are in the quote.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water heats radiators or underfloor heating and hot water; air-to-air heats rooms through indoor units and can cool them. With air-to-air, hot water needs another source, and we explain which suits your home.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How the job changes from property to property
Radiators and underfloor heating
At lower water temperatures, radiators give out less heat so we check them against each room’s heat loss.
Air-to-water heat pumps
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. A £7,500 grant may be available through the Boiler Upgrade Scheme for eligible homes and the installer applies.
After we have gone
Think of this as the after-treatment advice, short and simple:
- Diary the next service
- Check what your manufacturer’s warranty asks of you
- Let the heat pump run steadily, as set up at handover
The warranty on the heat pump is the manufacturer’s, on its own terms. We explain the terms for your brand, including any servicing conditions.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.

What happens on the day
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Pictures of the space and where the outdoor unit could go let us plan the work in New Denham.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- Installation follows on the agreed dates.
- We commission it, complete the MCS certificate and show you how to use it.
Preparing for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Unlock any gate, garage or side passage we need
- Let us know if the building has a permit or sign-in process

Air source heat pumps in New Denham: the local picture
New Denham’s centre is no more than about a third of a mile from the Uxbridge Lock Conservation Area. There are 6 conservation areas within a mile of the centre of New Denham. Historic England lists about 27 buildings and structures within half a mile of the centre of New Denham, including Dog and Duck Public House (grade II). For a heat pump, permitted development does not apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with the local planning authority (usually Hillingdon council) where necessary. VOA council tax data show about 37% of homes across New Denham and its surrounding area were built in 2000 or later, and the last census (2021) found about 50% of households live in flats. Newer homes typically lose less heat, which tends to suit a heat pump well. For flats, the first questions are where an outdoor unit could go, whether a cylinder fits and what the lease allows.
Ickenham Hall, roughly 2.1 miles east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings. Period properties close to St Francis can suit a heat pump, though insulation and any heritage protection are checked first.
