Air source heat pumps for homes and businesses in New Cross
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. The work covers homes heated by oil, LPG or gas, radiator systems and air-to-air heat pumps, and common reasons people get in touch are plans to switch to electric heating with a heat pump and ageing boilers that will need replacing.
A terrace in New Cross shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

After we’ve gone
Looking after the system is mostly common sense. A few tips:
- Keep the outdoor unit clear all year
- Use the settings explained at handover
- Find out the grant position at the survey
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes and it’s part of how the system works.
A well-insulated home helps a heat pump, as lower heat loss means the system has less to do.
FAQs for New Cross
Is planning permission needed for a heat pump in New Cross?
That depends on the building and where the outdoor unit goes. Central New Cross is a short walk from the Brockley 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 the planning department at Lewisham council, usually the authority for New Cross first.
Can I have air conditioning in a flat in New Cross?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Can I get the Boiler Upgrade Scheme grant?
That depends on the scheme conditions, which we check for you. The installer applies for the grant, so we handle the application if you are eligible.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
How do you keep the place clean during the 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.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How long will it take to install a heat pump?
Expect it to take a few days for most air-to-water installations, with air-to-air systems often quicker. How much of the heating changes decides most of the time, and we confirm the timing with your quote.

Landlords, agents and facilities managers
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
Running several properties is easier with one contractor. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
When it’s something else
It’s worth knowing the limits before booking:
- Tax rulings, which only HMRC can give
- Draught-proofing and insulation upgrades
- A grant for a home that doesn’t meet the scheme rules
If you’re not sure, just call us on 07833 053749 or drop us a line and we’ll give you a straight answer before booking.

How it works
If the system has to be off for part of the visit, we tell you before we start so it doesn’t catch you out. In a business, work can often be done one area at a time. The work 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. A few pictures of the room, the outside wall and the fuse board help us plan a job in New Cross.

Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from photos and measurements. After that, we send a fixed price before any work starts.

Air source heat pumps in New Cross: the local picture
About 43% of homes across New Cross and its surrounding area were built before 1919, according to Valuation Office Agency council tax records, and about 73% of households live in flats, according to Census 2021 figures. 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. A flat may have no room for a hot water cylinder, and the freeholder typically has a say on the outdoor unit, which can tip the choice towards air-to-air. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
If you live near New Cross station, the survey compares air-to-water and air-to-air for your home before anything is quoted. Older homes near St James's Church may need extra checks for planning and heat loss before a heat pump is designed.
