What the work involves, system by system
Air-to-water heat pumps
The price for air-to-water is £8,000–£16,000 (0% VAT on homes), before the grant. Eligible homes in England and Wales can get a £7,500 Boiler Upgrade Scheme grant towards it and the installer applies.
Air-to-air heat pumps
The £2,500 grant for air-to-air applies only when the system replaces the fossil-fuel heating and covers the whole home’s demand. It also has to be fitted by an MCS certified installer, in a home.
Air source heat pumps for homes and businesses in Penn Street
Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice. If you’re dealing with ageing boilers that will need replacing and wanting to stop using oil, LPG or gas for heating, we can sort it out.
Space for an outdoor unit is rarely an issue near Penn Street, so the design focuses on heat loss and radiators.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Questions from Penn Street
Does the Boiler Upgrade Scheme cover homes in Penn Street?
Penn Street is covered, as the scheme runs across England and Wales. 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. We hold MCS certification, so the application is ours to make for you.
Is a heat pump in Penn Street permitted development?
That depends on the building and where the outdoor unit goes. Central Penn Street is a short walk from the Penn Street Conservation Area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Buckinghamshire council, which is typically the planning authority for Penn Street.
Will skipping a service affect the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
Which type of heat pump is right for my home?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling. The survey helps decide. We install both types.
Can you come out in an emergency?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
When will I hear back?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
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 circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
How it works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Pictures of the space and where the outdoor unit could go let us plan the work in Penn Street.
- First we talk through the property and the current system.
- A heat loss survey is carried out, room by room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
Preparing for the visit
- Keep pets and children away from the work area
- Tell us about any building rules, permits or sign-in
- Tell us about access, such as roof hatches, high walls or locked plant areas

Air source heat pumps around Penn Street
Valuation Office Agency council tax records date about 42% of homes in and around Penn Street to the post-war years, 1945 to 1972, and about 78% of households live in detached or semi-detached houses, according to the 2021 Census. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Houses usually have space for an outdoor unit and a hot water cylinder.
Period properties close to Church of the Holy Trinity can suit a heat pump, though insulation and any heritage protection are checked first. With Hughenden Manor about 4.1 miles west, it’s worth asking whether your own home is listed before planning a heat pump.

What owners can safely do
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.

Aftercare tips
How well a system lasts depends on use and care. Here’s what we suggest:
- Store the MCS certificate and warranty documents together
- Read the manufacturer’s warranty terms for your brand
- Do not block radiators or indoor units with furniture
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes and it’s part of how the system works.
Keep insulation and draught-proofing in good order because it reduces the heat the system needs to supply.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
