What to know about air source heat pump installation in Teddington
Most homes can run on a heat pump if the system is designed properly, and Teddington is no different. The key is matching the heat pump and radiators to the home's heat loss.
Homeowners across Greater London can arrange a survey in Teddington for a room-by-room design and a written quote before committing to anything. For older properties in Teddington, 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.
- Owners who want one contract covering design, fitting and paperwork
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Houses with reasonable insulation, or a plan to improve it
What's included
- Radiator and pipework changes where the design needs them
- Outdoor unit, hot water cylinder and weather compensation controls
- Boiler Upgrade Scheme application in England and Wales where eligible
- Free home survey and room-by-room heat loss calculation
- System design, unit sizing and a written quote
Terraced streets in Teddington often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
Grants and rules for heat pumps in England
Homes in Teddington 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.
What to budget for air source heat pump installation in Teddington
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 Teddington can need quite different radiators and pipework.

|---|---|---|---|
| 1–2 bedroom flat or small terrace | 4–5 kW | £10,650–£14,000 | £3,150–£6,500 |
| 2–3 bedroom terrace or semi | 5–7 kW | £11,750–£15,100 | £4,250–£7,600 |
| 3 bedroom semi or small detached | 6–9 kW | £13,450–£17,350 | £5,950–£9,850 |
| 4 bedroom detached | 8–12 kW | £15,700–£20,150 | £8,200–£12,650 |

Designing for Teddington's winters
Teddington sees roughly 7 hours 50 minutes of daylight in late December against 16 hours 37 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 Teddington: questions
How long does a heat pump survey take in Teddington?
A home survey in Teddington usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
What size heat pump does a Teddington 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 Teddington home.
How soon can you survey a home in Teddington?
Survey dates depend on how busy installers are in Greater London. We offer the next available dates when you enquire and confirm them in writing.
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.
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.
