Frequently Asked Questions

Are solar panels free in the UK in 2025?

Solar panels are not universally free, but you may qualify for free installation through the ECO4 scheme if you receive certain benefits or have a household income under £36,000. Additionally, the 0% VAT rate effectively makes solar 20% cheaper for everyone.

How much can I earn from the Smart Export Guarantee?

SEG payments typically range from 3-15p per kWh exported, depending on your supplier. A typical 4kW system exporting 40% of generation (1,360 kWh/year) at 5p/kWh would earn around £68 annually. Higher tariffs like Octopus Outgoing (15p/kWh) could earn £204/year.

Can I get grants for solar battery storage?

Yes, battery storage is included in the 0% VAT relief when installed alongside solar panels. ECO4 may also cover battery storage in some cases. There are no specific standalone battery grants in 2025, but combined solar+battery installations qualify for all the same incentives as solar-only systems.

Do I need planning permission for solar panels?

Most residential solar installations don't require planning permission under permitted development rights. However, you may need permission if your property is listed, in a conservation area, or if panels significantly project above the roofline. Always check with your local authority.

How long does it take to get solar panels installed?

For private purchases, typical timeline is 4-8 weeks from quote to installation (survey, design, ordering, installation). For ECO4 funded installations, the process can take 8-16 weeks due to eligibility checks, surveyor visits, and approval processes.

Will solar panels increase my property value?

Yes, studies show solar panels can increase property value by 4-14% on average. They improve your EPC rating (making the property more attractive to buyers) and reduce energy bills, both of which are major selling points in today's market.
