Boiler Upgrade Scheme
Up to £9,000 off your heat pump
The government grant comes off your quote at the point of installation, so you never claim a rebate yourself.
Gas-heated homes
Replacing a gas boiler with an air source heat pump.
Oil or LPG homes (off the gas grid)
Increased grant for installations from 21 July 2026 to 31 March 2027. Common across the villages around Crawley.
- We apply to Ofgem for you
- Grant deducted from your quote
- Free survey and fixed quote
Biomass boilers and air-to-air heat pumps are not eligible for the uplift. A survey, design and Ofgem application all come before fitting, so book your free survey in good time rather than close to the deadline.
Why switch
Why Crawley homeowners are switching
Heat pumps turn one unit of electricity into around three units of heat, so they cost less to run than oil or LPG and are competitive with gas. Pair one with solar panels and a battery from the same team and you can power much of your heating from your own roof. We are based at Manor Royal, so your survey, design and installation are handled by our own team with no subcontractors.
Lower running costs
Far cheaper to run than oil or LPG, and competitive with gas for the right home.
Cleaner heating
No fuel burned at your property, which means no fumes and no fuel deliveries.
Works with solar
Add solar panels and a battery to power much of your heating from your own roof.
The basics
How does an air source heat pump work?
An air source heat pump takes heat from the outside air, even on cold Crawley days, and uses it to warm your radiators or underfloor heating and provide hot water, without burning any fuel. Think of it as a fridge in reverse: instead of removing heat from inside a fridge, it captures heat from the air outside and moves it into your home.

Questions answered
Heat pump FAQs
How much does a heat pump cost in Crawley, and what will I pay after the grant?
Cost depends on your home's size, heat loss and what needs upgrading, such as radiators or a hot water cylinder. After our free survey you get a fixed quote, and the Boiler Upgrade Scheme grant is deducted from it up front. You pay the balance, with no grant to claim back yourself.
What is the difference between the £7,500 and £9,000 grants?
Homes heated by gas get £7,500. Homes heated by oil or LPG, which means off the gas grid, get £9,000 for installations from 21 July 2026 to 31 March 2027. We confirm which applies to you at the survey and make the Ofgem application on your behalf.
Will a heat pump work in an older Crawley property?
Yes, with a proper heat loss survey and system design. Older homes may need larger radiators or some added insulation to run efficiently, and we tell you exactly what is needed before you commit.
Will a heat pump save me money compared with my boiler?
A heat pump delivers roughly three units of heat for every unit of electricity it uses, so it is far cheaper to run than oil or LPG and can compete with gas. Your actual saving depends on your tariff, your home and how you use heating. We go through realistic figures for your property at the survey.
Do I need a hot water cylinder or bigger radiators?
Most heat pump systems need a hot water cylinder, which matters if you have a combi boiler now. Some radiators may need upsizing so the system can heat your rooms at a lower flow temperature. Both are assessed and priced into your fixed quote.
Can I combine a heat pump with solar panels and a battery?
Yes, and it is one of the best ways to cut running costs. Solar can power a lot of your heating, and a battery stores the surplus. As we install solar, batteries and heat pumps ourselves, we can design them to work together. See our solar panels in Crawley and battery storage pages.
How long does installation take, and will I be without heating?
A typical installation takes two to three days. We plan the work to keep disruption to your heating and hot water as short as possible, and tell you what to expect before we start.
Why do you install Vaillant heat pumps?
Vaillant is an established German heating manufacturer, and we are a Vaillant accredited installer. We install Vaillant heat pumps such as the aroTHERM plus, and we will talk you through how it suits your home at your free survey.
Is a heat pump noisy?
Modern heat pumps run quietly, typically comparable to a domestic fridge. We position the unit to minimise noise for you and your neighbours.
Do I need planning permission for a heat pump in Crawley?
In most cases, no. Air source heat pumps in England are usually covered by permitted development rights, so you do not need to apply as long as the installation meets certain conditions. These include a noise limit at your neighbour's nearest habitable room, a size limit on the outdoor unit and not mounting it on a pitched roof. Listed buildings and some properties in conservation areas are treated differently, and flats have tighter limits. We check all of this at your survey and tell you whether planning is needed before you commit.
