Air source heat pumps in Sanderstead, done properly
An air-to-water heat pump heats water to a lower temperature than a typical boiler, so radiators may need to be larger to give out the same heat. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. Typical jobs include a boiler that’s getting old and checking whether planning permission is needed, on homes heated by oil, LPG or gas, underfloor heating and hot water cylinders.
A terrace in Sanderstead shares walls with its neighbours, which helps keep heat in, as long as there’s a sensible spot for the outdoor unit and its noise is checked against the MCS planning standard.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

Sanderstead: your questions answered
Can I get the Boiler Upgrade Scheme grant in Sanderstead?
Yes, if the home and the heat pump meet the scheme’s rules: Sanderstead is in England, where it applies. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. We hold MCS certification, so the application is ours to make for you.
Do I need permission to put air conditioning in my flat in Sanderstead?
Normally, 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.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
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, with F-Gas records where refrigerant work is involved.
Can I do any of the installation myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
How do you keep the place clean during the work?
Floors and furniture near the work are covered with dust sheets before we start, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
How much time does a heat pump install need?
As a guide, it 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 plan the work so you are without heating for as little time as possible, and we explain it in advance.

Let and managed properties
From a single flat to a whole estate, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
Keeping records across a portfolio is half the battle. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
Different systems, different jobs
Hot water cylinders
The cylinder size depends on how much hot water the household uses.
Radiators and underfloor heating
At lower water temperatures, radiators give out less heat so we check them against each room’s heat loss.
What air conditioning will not do
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- Promising eligibility for the Boiler Upgrade Scheme
- Any gas work on the existing boiler
- Tax advice on your own circumstances
If you are not sure, just call us on 07833 053749 or drop us a line and we will give you a straight answer before you book.

What a heat pump looks like in Sanderstead
About 39% of homes in Sanderstead and the neighbourhoods around it were built between the wars, according to Valuation Office Agency council tax records, and about 84% of households live in detached or semi-detached houses, according to Census 2021 figures. 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. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
If your home is one of the older properties near Church of All Saints, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Homeowners near Riddlesdown station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.
