Standard single-phase domestic heat pumps up to 16A per phase are registered under standard G98 'Connect & Notify' rules with Scottish and Southern Electricity Networks. Your accredited installer submits the paperwork to Scottish and Southern Electricity Networks within 28 days of commissioning with zero hassle to the homeowner.

Q: What are the running cost savings of a heat pump in Chichester compared to gas or oil?

Homes in Chichester 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.
