Cardiff buying questions
How much do solar panels cost in the UK?
A typical 4kW residential system costs £6,000–£8,500 installed, including scaffolding and MCS certification, and saves roughly £500–£900 a year on electricity.
Are heat pumps expensive to run?
A well-installed air source heat pump running on a heat pump tariff typically costs the same or less than a gas boiler per kWh of heat delivered, and much less once solar is added.
Why does MCS certification matter?
MCS certification is required to claim the Boiler Upgrade Scheme grant, the Smart Export Guarantee and most green mortgages.
How long does an install take?
Solar is usually one day. A heat pump conversion typically takes two to four days including commissioning and radiator upgrades.
