Frequently Asked Questions: Horsham Installations

How much does a heat pump cost in Horsham after the £7,500 grant?
For a standard 3-bedroom property in Horsham, an air source heat pump typically costs between £9,500 and £12,000 before grants. After deducting the statutory £7,500 Boiler Upgrade Scheme voucher, out-of-pocket costs average £2,000 to £4,500 with 0% VAT.
Do I need planning permission in Horsham?
In Horsham, most domestic heat pumps are Permitted Development (Class G) provided the outdoor unit is sited at least 1 metre from property boundaries and complies with MCS 020 sound standards (< 42 dBA). Listed buildings in West Sussex require listed building consent.
Who handles the £7,500 BUS grant application in West Sussex?
Your MCS certified installer applies directly to Ofgem on your behalf. You simply approve the email confirmation link sent by Ofgem, and the £7,500 is deducted directly from your final invoice.
Will I need to replace all my radiators in Horsham?
Most homes in Horsham keep 80%–95% of their existing radiators. When using modern high-temperature R290 heat pumps (such as the Vaillant aroTHERM Plus or Samsung EHS Mono HT), water flows at 55°C–70°C, meaning at most 1 or 2 smaller radiators in large rooms may need upgrading to double convector Type 22 units.
How does UK Power Networks process heat pump installations in Horsham?
Standard single-phase domestic heat pumps up to 16A per phase are registered under standard G98 'Connect & Notify' rules with UK Power Networks. Your accredited installer submits the paperwork to UK Power Networks within 28 days of commissioning with zero hassle to the homeowner.
What are the running cost savings in Horsham compared to gas or oil?
Homes in Horsham replacing an old gas boiler and switching to a smart heat pump electricity tariff (like Cosy Octopus) typically save £250–£550 per year. Properties replacing an oil tank or LPG system typically save £800–£1,400 annually.
