Air source heat pumps in Fortis Green
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. Common call-outs are for deciding which kind of heat pump suits the home and ageing boilers that will need replacing, on air-to-air heat pumps, homes heated by oil, LPG or gas and radiator systems.
In a London area like Fortis Green, many homes are flats or terraces with little outside space, which affects which heat pump suits. An air-to-water system needs space outside and usually a hot water cylinder inside, while an air-to-air system needs less space.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

System by system
Hot water cylinders
The cylinder size depends on how much hot water the household uses.
Air-to-air heat pumps
Air-to-air heat pumps are now covered by permitted development rules in England, subject to conditions. Cooling-only units are not included and need a check with the council.
What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any 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 freeholder or agent needs to agree the work in Fortis Green, we can send them the details.

A single unit or a whole estate, we price it on the same basis: what needs doing, how we get to it and what it needs. You’ll have a fixed price before work begins, with VAT shown clearly.

A well-insulated home helps a heat pump, as lower heat loss means the system has less to do.
Heat pumps in Fortis Green: local notes
The Valuation Office Agency’s council tax figures put about 56% of homes in the Fortis Green area before 1919, and about 56% of households live in flats, according to the 2021 Census. Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Period properties close to United Reformed Church can suit a heat pump, though insulation and any heritage protection are checked first. Heath Hall lies about 1.4 miles south-west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

Questions from Fortis Green
Can you fit air conditioning in a London flat in Fortis Green?
Often, yes, but the lease and the freeholder normally have a say. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Is planning permission needed for a heat pump in Fortis Green?
The answer turns on the property and where the outdoor unit would sit. Central Fortis Green is a short walk from the Muswell Hill Conservation Area. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Haringey council, which is normally the planning authority for Fortis Green first.
When will I hear back?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and explain why.
How long does a heat pump installation take?
Expect it to take anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. How much of the heating changes decides most of the time and the timing is set out with your quote.
How much VAT is charged on a heat pump in a home?
Homes pay 0% VAT on a heat pump installation until 31 March 2027, then 5%. Hotels and businesses pay the standard rate, and this isn’t tax advice.
