System by system
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger so we check them against each room’s heat loss.
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. We also consider neighbours and noise, as MCS 020(a) includes a noise check.
Air source heat pumps in Old Coulsdon, done properly
As an MCS certified installer, we fit air source heat pumps for homes in Old Coulsdon and the rest of Greater London. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We will explain which type fits your home and why. The work covers air-to-water heat pumps, radiator systems and underfloor heating, and the jobs we see most are a boiler that’s getting old and questions about the Boiler Upgrade Scheme.
Terraced houses in a London area like Old Coulsdon can suit a heat pump well, as long as there’s a sensible spot for the outdoor unit and its noise is checked against the MCS planning standard.
Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

Old Coulsdon: your questions answered
Will a heat pump in Old Coulsdon need planning permission?
The answer turns on the property and where the outdoor unit would sit. Historic England lists about 6 buildings and structures within half a mile of the centre of Old Coulsdon. 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 Croydon council, normally the authority for Old Coulsdon first.
Can you fit air conditioning in a London flat in Old Coulsdon?
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.
What does an air-to-water heat pump cost?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
How does the warranty work?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Does the grant cover air-to-air heat pumps?
Sometimes, and the amount is £2,500 rather than £7,500. The system has to replace the fossil-fuel heating and heat the whole home with an MCS certified installer.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Tell us who should receive the paperwork.
Why does F-Gas certification matter?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Keep up with insulation and draught-proofing
- Leave space around the outdoor unit
- Know the servicing conditions in your warranty
If anything does not seem right after installation, ring us on 07833 053749 or drop us a line and we will look into it. A yearly service is a good habit.
Keep the outdoor unit clear of leaves, plants and stored items. Airflow is what it runs on, so keep it clear all year.
Why deal with it now?
For eligible off-gas homes on oil or LPG, an extra £1,500 is on offer until March 2027. For homes that qualify, that is a reason to look into it now. Allow time for any approvals your building in Old Coulsdon needs.
Every job is different, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all make a difference.

Air source heat pumps in Old Coulsdon: the local picture
The Valuation Office Agency’s council tax figures date about 47% of homes in the Old Coulsdon area to the post-war years, 1945 to 1972, and about 76% of households live in detached or semi-detached houses, according to the last census (2021). Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Live in one of the older houses around Church of St John the Evangelist? Expect the survey to look closely at heat loss and at the building’s planning status. Addington Palace lies about 5 miles north-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
