How we handle air source heat pumps in Bush Hill
In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. The work covers air-to-water heat pumps, radiator systems and underfloor heating, and the jobs we see most are radiators that may be too small for a heat pump and comparing heat pump types.
For flats in Bush Hill, the lease, the freeholder and the rules for flats all come into it. Permitted development limits are different for flats, so we check the position before we design.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer and it’s worth keeping safe.

Bush Hill: your questions answered
Can I fit a heat pump in Bush Hill without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. A conservation area takes in the middle of Bush Hill. 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 the planning department at Enfield council, typically the authority for Bush Hill.
Can I get the Boiler Upgrade Scheme grant in Bush Hill?
Yes, the scheme covers homes in England, including Bush Hill, if they qualify. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You do not apply yourself: the MCS certified installer does, which is us.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Keep every service record either way.
What accreditations do you have?
As the law requires for refrigerant work, we’re an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We are happy to quote for the full job, supply to commissioning.
What’s the price of a heat pump installation?
£8,000–£16,000 (0% VAT on homes) for air-to-water, before the grant. Your price depends on the survey, the emitters and the hot water and the quote is fixed.
Will my radiators work with a heat pump?
It depends on each radiator and the room it heats. At the lower temperatures a heat pump uses, radiators need more surface, and the survey checks each one.
Rented and managed buildings
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we’re happy to deal with whoever it is.
What a heat pump looks like in Bush Hill
About 39% of homes across Bush Hill and its surrounding area were built between the wars, according to VOA council tax data. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Period properties close to Grange Park Methodist Church can suit a heat pump, though insulation and any heritage protection are checked first. Forty Hall, roughly 2.1 miles north, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.
Bush Hill is about 1 mile south of Enfield, in Greater London. Whether you are in the middle of Bush Hill or further out, we cover air source heat pumps, from a single room to a whole building.

Safe owner checks
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. If you need something moved, we can quote for it.
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. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.

Aftercare tips
A little care keeps the system in better shape. Our advice:
- Know the servicing conditions in your warranty
- Seal draughts where you can
- Avoid switching the heat pump on and off often
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.
Let the heat pump run steadily rather than switching it on and off as explained at handover.
What happens on the day
Testing is the last part of the visit wherever the system can be switched on. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. The visit takes from a couple of days to around a week, depending on the system and how much of the heating changes. Parking bays, permits and roof or balcony access are the first things we ask about in Bush Hill.
- It starts with a conversation about the home, the existing heating and your plans.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Before we arrive
- Name a contact who can meet us at the agreed time
- Let us know where we can park and unload
