About our air source heat pumps in Seven Sisters
Many air source heat pumps can be installed as permitted development in England, without a planning application. 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 underfloor heating, hot water cylinders and air-to-air heat pumps, and people most often call us about an oil, LPG or gas boiler near the end of its life and comparing heat pump types.
In a flat in Seven Sisters, the lease and the freeholder typically decide where a heat pump can go. The planning rules for flats are stricter than for houses, and we check before designing.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

Keeping the system healthy
Every system needs looking after, and most of it is easy. Our tips:
- Read the manufacturer’s warranty terms for your brand
- Seal draughts where you can
- Leave indoor units unobstructed
Should you have questions after the install, call us on 07833 053749 and we will talk it through. A yearly service is a good habit.
Keep insulation and draught-proofing in good order, as lower heat loss means the system has less to do.
What happens if it’s left?
The 0% VAT rate on heat pumps in homes runs until 31 March 2027, then 5% applies. If you are thinking about a heat pump, that date is worth knowing alongside your own plans for the property. Getting the work done in Seven Sisters before summer avoids the busiest weeks.
What you pay depends on the system and the number of rooms or units, the access and the parts and time the job needs. You get a fixed price before work begins, so you know where you stand.

Common questions in Seven Sisters
Does the Boiler Upgrade Scheme cover homes in Seven Sisters?
Seven Sisters is covered, as the scheme runs across England and Wales. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. We hold MCS certification, so the application is ours to make for you.
Is planning permission needed for a heat pump in Seven Sisters?
The answer turns on the property and where the outdoor unit would sit. Historic England lists about 22 buildings and structures within half a mile of the centre of Seven Sisters. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Seven Sisters, typically Haringey council).
Do you cover Seven Sisters?
Yes. Our engineers work in Seven Sisters, as part of our area across London and the South East. We’re based in East Grinstead, West Sussex.
Do you protect the property while you work?
Protection goes down first: sheets over the floor and nearby furniture. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
Do I need new radiators for a heat pump?
We find out during the survey. Where a radiator is already large enough, it stays and any changes are in the quote.
Which accreditations do you hold?
We’re an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re also Checkatrade members.
Before you call an engineer
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.

The process
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then the work itself, and finally we test, record and explain. Most of the time goes on the middle part, and that takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Some blocks in Seven Sisters need contractor details in advance, so tell us what your building needs.
- We find out about your home and the heating you have now.
- A heat loss survey is carried out, room by room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- You get a fixed price, with any grant and the VAT set out.
- Then it’s fitted, commissioned and registered with MCS.
How to prepare
- Make sure someone can let us in at the agreed time
- Find the manual or the paperwork for the system, if you have it
- Unlock any gate, garage or side passage we need
Ask for a quote
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price so you know the cost before we begin.

Heat pumps in Seven Sisters: local notes
About 54% of homes in Seven Sisters and the neighbourhoods around it were built before 1919, according to Valuation Office Agency council tax records, and the 2021 Census found about 59% of households live in flats. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. In flats, space for an outdoor unit and a cylinder can be limited, and the lease and freeholder come into it, so air-to-air is sometimes the better fit. For a London home, the outdoor unit position and the MCS noise check need careful planning.
With Bruce Castle about 1.2 miles north, it’s worth asking whether your own home is listed before planning a heat pump. Older homes near Church of Holy Trinity may need extra checks for planning and heat loss before a heat pump is designed.
