Air source heat pumps in Croxley Green: the local picture
VOA council tax data show about 46% of homes in the Croxley Green area date from 1919 to 1939, and about 68% of households live in detached or semi-detached houses, according to the 2021 Census. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder.
With Chenies Manor House about 4.2 miles north-west, it’s worth asking whether your own home is listed before planning a heat pump.

How we handle air source heat pumps in Croxley Green
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. Common call-outs are for deciding which kind of heat pump suits the home and planning and permitted development questions, across underfloor heating, air-to-air heat pumps and hot water cylinders.
In a place like Croxley Green, some homes are listed, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

Common problems we fix in Croxley Green
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. The grant only applies in some cases, so we check first.
It’s time to call us if you are dealing with:
- Deciding which kind of heat pump suits the home
- Plans to switch to electric heating with a heat pump
- An oil, LPG or gas boiler near the end of its life
Older homes near St Oswald's Parish Church may need extra checks for planning and heat loss before a heat pump is designed.

The process
On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. The work itself 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. Rural lanes and tight entrances are worth mentioning before a visit to Croxley Green.
- We start with your plans and the property.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- We install the heat pump and connect it up.
- After commissioning, you get the MCS certificate and a handover.
Before we arrive
- Unlock any gate, garage or side passage we need
- Let us know if the units are on a roof, a high wall or in a locked area
- Tell us about any building rules, permits or sign-in

Your questions about air source heat pumps in Croxley Green
Is a heat pump in Croxley Green permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The Croxley Green, Dickinson Square Conservation Area is close to the centre of Croxley Green. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where necessary, we check with the planning department at Three Rivers council, usually the authority for Croxley Green.
Does the Boiler Upgrade Scheme cover homes in Croxley Green?
Yes, if the home and the heat pump meet the scheme’s rules: Croxley Green 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. As an MCS certified installer, we apply for it on your behalf.
Do I need to service the system to keep the warranty?
It can, for some brands. Read the manufacturer’s terms, or send us the make and model and we’ll explain them, and book the service at the interval they recommend.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
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. The final price depends on the heat loss survey, the radiators and the cylinder and the quote is fixed.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
Different systems, different jobs
Hot water cylinders
Existing cylinders may not be suitable for a heat pump and we tell you if it needs replacing.
Air-to-water heat pumps
Air-to-water systems take heat from the air and put it into your central heating and hot water. It replaces the boiler as the main heat source, and is MCS certified when we install it.
Keeping the system healthy
A little care keeps the system in better shape. Our advice:
- Do not block radiators or indoor units with furniture
- Seal draughts where you can
- Avoid switching the heat pump on and off often
Equipment warranties come from the manufacturer. We explain the terms for your brand, including any servicing conditions.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.
