Air source heat pumps in Netherne on-the-Hill, done properly
A £2,500 grant is available for some air-to-air heat pumps, with conditions. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home, so an add-on next to a boiler is not eligible. We are often asked to deal with checking whether planning permission is needed and questions about the Boiler Upgrade Scheme, across homes heated by oil, LPG or gas, underfloor heating and radiator systems.
In a London area like Netherne on-the-Hill, many homes are flats or terraces with little outside space, which affects which heat pump suits. Air-to-water needs room for the outdoor unit and typically a cylinder, while air-to-air units take less room.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Different systems, different jobs
Air-to-water heat pumps
Flow temperatures are lower than with a typical boiler, so radiator sizes matter.
Air-to-air heat pumps
Air-to-air heat pumps warm rooms through indoor units and can cool them in summer. Hot water needs a separate source so you will need another way to heat it.
Landlords, agents and facilities managers
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
We regularly work with managing agents. Tell us the property, the work and the access arrangements and we’ll come back with a fixed-price quote.
Air source heat pumps around Netherne on-the-Hill
About 47% of homes in the Netherne on-the-Hill area date from 1945 to 1972, according to Valuation Office Agency council tax records, and the 2021 Census found about 76% of households in detached or semi-detached houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Every heat pump design starts with a room-by-room heat loss calculation. If your home is one of the older properties near Church of St Margaret, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

Advice
Questions from Netherne on-the-Hill
Can you fit air conditioning in a London flat in Netherne on-the-Hill?
In many cases, yes, once the lease and the building’s rules are checked. 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.
Can I fit a heat pump in Netherne on-the-Hill without planning permission?
It depends on the property. The Netherne-on-the-Hill Conservation Area takes in the middle of Netherne on-the-Hill. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where necessary, we check with the planning department at Reigate and Banstead council, typically the authority for Netherne on-the-Hill.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re members of Checkatrade too.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.
How long does a heat pump installation take?
As a guide, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. We plan the work so you are without heating for as little time as possible and agreed before we start.
Do you offer emergency call-outs?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
