Before you book: air source heat pump installation in Highbury
Most homes can run on a heat pump if the system is designed properly, and Highbury is no different. The key is matching the heat pump and radiators to the home's heat loss.
In Highbury, cylinder space is planned with you, often in an airing cupboard, utility room or garage. For older properties in Highbury, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
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 who want one contract covering design, fitting and paperwork
What's included
- MCS registration and certificate, plus network operator notification
- 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
- Boiler Upgrade Scheme application in England and Wales where eligible
Many homes in Highbury 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 Highbury 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.
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.

Designing for Highbury's winters
On the shortest day Highbury gets about 7 hours 49 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 system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Highbury: questions
How long does installation take in Highbury?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Highbury home states the expected time.
Can you service a heat pump in Highbury that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Highbury, whoever fitted them. Tell us the make and model when you book.
Do you cover Islington as well as Highbury?
Yes. We arrange surveys and installation in Islington, which is about a mile south of Highbury, and across Greater London.
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.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
