About our air source heat pumps in North Harrow
Hot water from an air-to-water system is stored in a cylinder. If you have a combi boiler and no cylinder, the survey looks at where one could go. With air-to-air, hot water has to come from something else. The work covers air-to-water heat pumps, homes heated by oil, LPG or gas and radiator systems, and the jobs we see most are no space for a hot water cylinder and questions about the Boiler Upgrade Scheme.
In a London area like North Harrow, many homes are flats or terraces with little outside space, and that decides which kind of heat pump works. Air-to-water needs room for the outdoor unit and normally a cylinder, while air-to-air units take less room.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

What air conditioning will not do
A few issues sit outside what this work can do:

Questions from North Harrow
Can I fit a heat pump in North Harrow without planning permission?
That depends on the building and where the outdoor unit goes. A conservation area takes in the middle of North Harrow. 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 the planning department at Harrow council, usually the authority for North Harrow first.
Do I need permission to put air conditioning in my flat in North Harrow?
Usually, yes, though leaseholders normally need the freeholder’s agreement. 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.
Do you cover North Harrow?
Yes. North Harrow is part of the area we cover, as part of our area across London and the South East. We’re based in East Grinstead, West Sussex.
How much time does a heat pump install need?
An installation 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. We confirm the timing after the survey, and you can call us on 07833 053749 or use the quote form to book it.
Are my radiators big enough for 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 so we check every radiator against the room’s heat loss.
Do you work for landlords and businesses?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Do you protect the property while you work?
We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
The process
Each visit runs to the same pattern: agree the plan on site, protect the area, do the work, check the system and talk you through it. On site, the work takes from a couple of days to around a week, depending on the system and how much of the heating changes. Photos of the room and where the outdoor unit could go let us plan most of a visit to North Harrow in advance.
- It begins with your house and the heating it relies on now.
- Every room’s heat loss is worked out on site.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- We install, commission and register the system under MCS.
How to prepare
- Let us know where we can park and unload
- Move furniture away from the wall where we will be working
- Make sure we can reach the consumer unit or fuse board
How to get a quote
Every quote shows the VAT clearly, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. For a fixed-price quote, phone 07833 053749 or fill in the contact form.

Heat pumps in North Harrow: local notes
Valuation Office Agency council tax records show about 54% of homes in North Harrow and the neighbourhoods around it date from 1919 to 1939. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Period properties close to Church of St Alban can suit a heat pump, though insulation and any heritage protection are checked first.

It’s time to call us if you’re dealing with:
- Deciding on the outdoor unit position
- Not knowing whether a grant applies
- Planning and permitted development questions
