Before you book: air source heat pump installation in Billericay
The question for a Billericay home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
For older properties in Billericay, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized. Homeowners across Essex can arrange a survey in Billericay 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
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
What's included
- Radiator and pipework changes where the design needs them
- System design, unit sizing and a written quote
- 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
Terraced streets in Billericay 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 Billericay 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 Billericay and what they mean
Billericay has about 7 hours 48 minutes of daylight at midwinter and 16 hours 40 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Air source heat pump installation in Billericay: questions
How long does installation take in Billericay?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Billericay home states the expected time.
What size heat pump does a Billericay 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 Billericay home.
Where would the outdoor unit go on a Billericay 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 Billericay 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.
