Air source heat pump installation in Croydon: what to expect
A heat pump suits most Croydon homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For older properties in Croydon, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. In Croydon, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Households with room for a hot water cylinder
- Homes replacing a gas, oil, LPG or electric heating system
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Removal of the old boiler or heaters
- System design, unit sizing and a written quote
- Commissioning, handover and a walk-through of the controls
- MCS registration and certificate, plus network operator notification
- Outdoor unit, hot water cylinder and weather compensation controls
Many homes in Croydon have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
Grants and rules for heat pumps in England
Homes in Croydon can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

How long is the heating season in Croydon?
On the shortest day Croydon gets about 7 hours 51 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.
The steps for air source heat pump installation in Croydon
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Croydon; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Air source heat pump installation in Croydon: questions
Do you cover Purley as well as Croydon?
Yes. We arrange surveys and installation in Purley, which is about 3 miles south of Croydon, and across Greater London.
How long does installation take in Croydon?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Croydon home states the expected time.
What size heat pump does a Croydon home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Croydon home.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
