Renewable Energy

A typical 4kW solar panel system costs £5,000-£8,000. With battery storage, expect £8,000-£14,000.

A typical household saves £300-£500 per year on electricity bills, plus income from the Smart Export Guarantee.

The government offers £7,500 towards heat pump installation costs, significantly reducing the upfront investment.

Yes. Solar panels work with daylight, not direct sunlight. The UK receives enough solar radiation for panels to generate significant electricity, even on cloudy days. A south-facing roof at 30-40 degrees is optimal.

Most solar panels come with a 25-year performance warranty and can last 30-40 years. They degrade by about 0.5% per year. Inverters typically last 10-15 years and may need replacing once during the panel lifespan.

An air source heat pump extracts heat from outdoor air to heat your home and hot water. It works like a fridge in reverse. ASHPs cost £7,000-£14,000 installed before the £7,500 Boiler Upgrade Scheme grant.

Solar panels usually fall under permitted development for most homes, meaning no planning permission is needed. Exceptions include listed buildings, conservation areas, and panels that protrude more than 200mm from the roof surface.

A home EV charger costs £800-£1,500 installed, including a 7kW wallbox unit. Smart chargers are required for the OZEV grant. Installation typically takes 2-4 hours.
