Air source heat pumps in Purley, done properly
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. Air-to-air systems do not heat hot water, so you’ll need another way to do that. The work covers underfloor heating, hot water cylinders and air-to-water heat pumps, and people most often call us about deciding on the outdoor unit position and plans to switch to electric heating with a heat pump.
In a London area like Purley, many homes are flats or terraces with little outside space, which affects which heat pump suits. An air-to-water system needs space outside and normally a hot water cylinder inside, while an air-to-air system needs less space.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Air source heat pumps in Purley: the local picture
About 31% of homes in Purley and the neighbourhoods around it were built between the wars, according to VOA council tax data, and about 62% of households live in detached or semi-detached houses, according to Census 2021 figures. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. For a London home, the outdoor unit position and the MCS noise check need careful planning.
For a home near Purley station, the survey looks at whether an air-to-water or air-to-air heat pump suits better. Live in one of the older houses around St Swithun's? Expect the survey to look closely at heat loss and at the building’s planning status.

Leave it or put it right?
If the emitters cannot give out enough heat, some rooms will not get warm enough. Checking and upsizing them as part of the installation avoids that. In a London building, getting the freeholder’s or agent’s agreement can take a while, so it’s worth starting early.
What you pay depends on the type of system and how many units are involved, the access and what the work involves. We give you a fixed price before we start, so there are no surprises.
What you get with us
- 24/7 emergency line for breakdowns

How the job changes from property to property
Radiators and underfloor heating
Underfloor heating suits a heat pump’s lower flow temperature, and we can connect to it where it’s already in.
The Boiler Upgrade Scheme
In England and Wales, the Boiler Upgrade Scheme offers grants towards heat pumps: £7,500 for air-to-water (and ground source), and £2,500 for air-to-air with strict conditions. The application goes through the installer.
The process
The visit goes in the diary at a time that works for you, and we keep you posted if anything changes. When we arrive, we check the job against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. In a London area like Purley, parking and access are worth sorting out before the day.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Dig out any previous service or F-Gas records
- Unlock any gate, garage or side passage we need
- Mention any roof access, ladders or high-level work
Getting a price
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Your questions about air source heat pumps in Purley
Can I fit a heat pump in Purley without planning permission?
The answer turns on the property and where the outdoor unit would sit. Historic England lists about 3 buildings and structures within half a mile of the centre of Purley. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Croydon council, which is typically the planning authority for Purley.
Can I have air conditioning in a flat in Purley?
Normally, yes, though leaseholders normally need the freeholder’s agreement. 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.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s 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.
When will I hear back?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
Do you provide F-Gas records?
Yes. You get a written record of every visit, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
