What to know about air source heat pump installation in Egham
Most homes can run on a heat pump if the system is designed properly, and Egham is no different. The key is matching the heat pump and radiators to the home's heat loss.
For older properties in Egham, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Homeowners across Surrey can arrange a survey in Egham for a room-by-room design and a written quote before committing to anything.
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.
- Homes replacing a gas, oil, LPG or electric heating system
- Households with room for a hot water cylinder
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Commissioning, handover and a walk-through of the controls
- Free home survey and room-by-room heat loss calculation
- MCS registration and certificate, plus network operator notification
- Removal of the old boiler or heaters
- Radiator and pipework changes where the design needs them
In Egham, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Grants and rules for heat pumps in England
Homes in Egham 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.

Short winter days in Egham and what they mean
Egham sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 38 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

Air source heat pump installation in Egham: questions
How soon can you survey a home in Egham?
Survey dates depend on how busy installers are in Surrey. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on an Egham 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 Egham home.
Do I need new radiators for a heat pump in Egham?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Egham home gives a room-by-room list.
Will an air source heat pump be noisy?
Heat pumps are designed to run quietly, but where the unit sits makes a real difference. The survey looks for a position away from bedroom windows and neighbours, with clear airflow, and the installation must pass the MCS noise assessment. The fan is most noticeable on very cold days when the unit works hardest, and a little vapour during the periodic defrost is normal.
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.
