The main concerns people have on installing solar, answered

Homeowners usually hesitate for practical reasons rather than technical ones: what it costs, who to trust, and whether it will work for their home.

How affordable is solar?

The modelled system averages £7,844.50 upfront with payback of around 7.9 years. 0% VAT applies until 31 March 2027, and other support may be available. Affordability varies by household, so a personal estimate helps.

Where do I start?

Assess your roof first. Emily shows system options with estimated generation, annual savings and payback. When comparing installers, look for MCS certification.

Does solar work across the UK?

Yes. Every UK country showed average estimated savings above £800 a year, though your own result depends on your roof, location, usage and design.
