How we handle air source heat pumps in St Ann's
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. Common call-outs are for no space for a hot water cylinder and checking whether planning permission is needed, on radiator systems, homes heated by oil, LPG or gas and underfloor heating.
Homes in St Ann's are often flats and terraces, where outside space is limited, which affects which heat pump suits. An air-to-water system needs space outside and typically a hot water cylinder inside, while air-to-air units take less room.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Common questions in St Ann's
Is a heat pump in St Ann's permitted development?
The answer turns on the property and where the outdoor unit would sit. The centre of St Ann's is in the St Ann's 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 usually the planning authority for St Ann's first.
Can I get the Boiler Upgrade Scheme grant in St Ann's?
Yes, if the home and the heat pump meet the scheme’s rules: St Ann's is in England, where it applies. 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. The installer applies, and we’re MCS certified.
What’s the price of a heat pump installation?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder. Air-to-air is priced after a survey.
How long does a heat pump installation take?
It takes a few days for most air-to-water installations, with air-to-air systems often quicker. The cylinder, the radiators and the pipework make the biggest difference and the timing is set out with your quote.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
What affects the cost of air source heat pumps
Your quote is based on your property. We take into account:
- What we find on the survey or diagnosis
- How easy the units are to reach
- Which make and model is being fitted or worked on
The price reflects the work, not guesswork. That’s why every job is looked at first, and the price is agreed before any work starts.
What we need to know
When you call or email, these details help:
- The make and model of the system, from the label
- The paperwork from the last service, if you have it
- Where the outdoor unit is, or where you’d like it
To help us quote: the address and the type of property, photos of the rooms or units, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Then phone us on 07833 053749 or write to us at info@aircondoctor.co.uk.

Rented and managed buildings
If you look after several properties, we can plan visits across the portfolio and price them together. Each property gets its own records, so each one has its own history.
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
How the visit works
Each visit runs to the same pattern: check the plan with you, protect the area, carry out the job, test what we’ve done and talk you through it. The visit itself takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Some blocks in St Ann's need contractor details in advance, so tell us what your building needs.
- It starts with a conversation about the home, the existing heating and your plans.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Dig out any previous service or F-Gas records
- Make sure we can reach the consumer unit or fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits

Heat pumps in St Ann's: local notes
VOA council tax data put about 54% of homes in the St Ann's area before 1919, and about 63% of households live in flats, according to the last census (2021). In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. 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.
Live in one of the older houses around St Ann's Church? Expect the survey to look closely at heat loss and at the building’s planning status. For a home near Seven Sisters station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.
