Our coverage in West Sussex runs from Crawley, Worthing, Bognor Regis and Littlehampton and the villages around them. The approach is the same everywhere: survey, design, a written quote, then installation by installers working under our contract.

Grants and rules for heat pumps in England
Homes in West Sussex 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.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Questions
What happens at the home survey?
The home survey is a visit to measure your home room by room and calculate its heat loss, which sets the size of heat pump and radiators you need. We also look at your existing radiators and pipework, where the cylinder and outdoor unit can go, your electricity supply and the position of neighbouring homes for the noise check. Afterwards you receive a written quote with the system design and price. See heat loss surveys.
Should I leave my heat pump running all the time?
Usually yes: a heat pump works most efficiently running steadily at a low flow temperature, rather than switching on and off like many boilers. Weather compensation controls adjust the flow temperature to the weather outside, so the system keeps rooms comfortable using less energy. You can still lower temperatures overnight or when you are away, but large set-backs make the heat pump work harder to recover. We set up the controls and show you how they work.
What heat pump grants can I get, and does it depend on where I live?
The grant you can get depends on which UK nation you live in. In England and Wales, the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. In Scotland, Home Energy Scotland offers a grant of up to £7,500, more for eligible rural and island homes, plus an optional interest-free loan. Northern Ireland has no dedicated heat pump grant for homeowners at present. See heat pump grants.
Who is eligible for the Boiler Upgrade Scheme?
You are usually eligible for the Boiler Upgrade Scheme if you own an existing home in England or Wales, including as a landlord, and are replacing fossil-fuel or electric heating. The new system must meet the home's full heating and hot water needs. Most new builds, social housing, homes already funded for a heat pump and hybrid systems are not eligible. Air-to-air heat pumps in homes can get a separate £2,500 grant from 28 April 2026. We check eligibility at survey.
