What owners can safely do
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Air source heat pumps in Ilmer, done properly
For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, and as the installer we apply for it on your behalf. Eligibility depends on the property, so we confirm it before anything is agreed. If the problem is not knowing whether a grant applies and radiators that may be too small for a heat pump, we can sort it out.
In a place like Ilmer, 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. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Looking after it afterwards
To keep the system working properly:
- Keep the MCS certificate with the manufacturer’s paperwork
- Look at insulation alongside the heat pump
- Know the servicing conditions in your warranty
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.
Keep radiators and indoor units unobstructed, as the system relies on them giving out heat.
What we’re called out for in Ilmer
People also ask about air-to-air heat pumps because they heat and cool. They warm rooms directly through indoor units and switch to cooling in warm weather. Whether a grant applies depends on the scheme conditions.
It’s time to call us if you’re dealing with:
- Plans to switch to electric heating with a heat pump
- Checking emitters for a heat pump
- An oil, LPG or gas boiler near the end of its life
Period properties close to Church of St Peter can suit a heat pump, though insulation and any heritage protection are checked first.
Before you book anyone
- Whether the quote is a fixed price
- How extra work would be agreed if they find something unexpected
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
What we do, step by step
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. All told, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. If a lane or gateway near Ilmer is tight for a van, let us know and we will plan for it.
- It begins with your house and the heating it relies on now.
- Every room’s heat loss is worked out on site.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
Before we arrive
- Make sure we can reach the consumer unit or fuse board
- Let us know if the building has a permit or sign-in process
- Name a contact who can meet us at the agreed time

Heat pumps in Ilmer: local notes
Central Ilmer is inside the Ilmer Conservation Area. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where necessary, we check with the local planning authority (typically Buckinghamshire council). About 30% of homes in the Ilmer area have been built since 2000, according to Valuation Office Agency council tax records, and Census 2021 figures found about 79% of households in detached or semi-detached houses. Better insulated, newer homes are often a good match for a heat pump. Houses normally have space for an outdoor unit and a hot water cylinder.
A heat loss calculation decides the size of heat pump your home needs.

FAQs for Ilmer
Do you cover smaller places like Ilmer?
Yes. Ilmer is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Can I get the Boiler Upgrade Scheme grant in Ilmer?
Yes, if the home and the heat pump meet the scheme’s rules: Ilmer is in England, where it applies. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. The installer applies, and we’re MCS certified.
How much time does a heat pump install need?
As a guide, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. The programme is planned to keep time without heating short, and we explain it in advance.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we are Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
What does an air-to-water heat pump cost?
Air-to-water systems are £8,000–£16,000 (0% VAT on homes), before any grant. Your price depends on the survey, the emitters and the hot water, and you get a fixed-price quote.
Can landlords and managing agents book you?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: a look first, a fixed-price quote and written records.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for instance, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
