Why consider renewables now?

The Ofgem price cap has risen dramatically since 2021. The bar chart below updates each quarter. With the recent political events in the Middle East, the case for subsidising energy costs with solar is stronger than ever.

What can Renewables do to help?

Renewables can help you take greater control of your energy costs by installing solar panels to power your home during the day and pairing them with battery storage to store unused electricity for later. Instead of sending surplus energy back to the grid, your battery can store it for use in the evening, when your household typically needs more power. The system can also be set to charge your battery overnight at cheaper off-peak electricity rates, giving you another smart way to reduce your bills and make your home more energy-efficient all year round.

Common questions, honest answers

The questions people actually ask before going solar — answered plainly.

Yes — PVGIS data for Fife and Central Scotland shows 850–1,000 kWh/kWp annually. Combined with current energy prices, returns on solar investment are strong and continue to improve as bills rise.

The SEG requires licensed energy suppliers to pay you for electricity your solar panels generate and export back to the grid. Rates currently range from 4p to 15p per kWh depending on your supplier. See the rate comparison table on this page for current figures.

A typical residential installation takes 1–2 days. GSM handles scaffolding, installation, DNO notification, and grid connection — so there's nothing for you to arrange separately.

In most cases, solar panels on a pitched roof fall under Permitted Development rights and do not require planning permission. Listed buildings and conservation areas may require a separate planning application — GSM will advise during your free site survey.

It depends on your usage pattern. If you're away from home during the day, a battery allows you to use solar-generated electricity in the evening — significantly improving your self-consumption rate and overall annual saving. Our battery comparison tool above gives you a personalised answer.

GSM provides a 10-year workmanship guarantee on all installations. Panel manufacturers typically offer 25-year performance warranties. Inverters carry a 5–12 year warranty depending on the brand specified.
