What to know about air source heat pump installation in Enfield
Homes around Enfield range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Homeowners across Greater London can arrange a survey in Enfield for a room-by-room design and a written quote before committing to anything. In Enfield, 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
- Houses with reasonable insulation, or a plan to improve it
- Homes replacing a gas, oil, LPG or electric heating system
What's included
- Commissioning, handover and a walk-through of the controls
- Outdoor unit, hot water cylinder and weather compensation controls
- Removal of the old boiler or heaters
- System design, unit sizing and a written quote
- MCS registration and certificate, plus network operator notification
Many homes in Enfield 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
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Enfield quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.
Air source heat pump installation costs around Enfield
The ranges below are typical installed prices for homes in Greater London, including VAT. A survey sets the exact figure, because two similar-looking houses in Enfield can need quite different radiators and pipework.

Short winter days in Enfield and what they mean
On the shortest day Enfield gets about 7 hours 48 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

- Installers fit the unit, cylinder and any radiator changes, typically over 2–4 days on site.
- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Enfield: questions
How long does installation take in Enfield?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Enfield home states the expected time.
Can you service a heat pump in Enfield that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Enfield, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on an Enfield house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Enfield home.
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.
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.
