Funding & Incentives

What's available for commercial solar

There's currently no dedicated capital grant for commercial solar, but most sites still benefit from real financial incentives:

  • Capital allowances — solar equipment typically qualifies for tax relief against profits
  • The Smart Export Guarantee (SEG) — get paid for electricity you generate and export back to the grid
  • Reduced ongoing energy costs from day one, without waiting on a grant application

We factor all of this into the cost and payback figures in your feasibility assessment.

Is Solar Right For You

Who commercial solar works best for

A good fit if

  • Sites with a large, unshaded roof or unused land area
  • Businesses with high daytime electricity usage
  • Owner-occupied sites, or long leases with landlord buy-in
  • Sites already facing rising energy costs

Worth a conversation first if

  • Your roof is heavily shaded or near end-of-life and needs replacing first
  • You're on a short lease with no landlord agreement in place
  • Your site's usage is mostly overnight, not daytime
  • You're not sure yet — a feasibility assessment will tell you
FAQs

Common questions

How much roof or land space do I need?+

It depends on your usage, but as a guide most commercial systems start from around 20–30 panels. We'll confirm exact space needed during the site survey.

Do I need planning permission?+

Most commercial rooftop solar falls under permitted development, but listed buildings, conservation areas and ground-mount systems can need permission. We check this as part of the process.

How long does installation take?+

A typical commercial installation takes 1–3 weeks on site, depending on system size, though timelines vary by site complexity.

What happens if I move or sell the site?+

Solar systems typically add asset value. We can talk through options for leased vs owned sites during your feasibility assessment.

Can I combine solar with EV charging or battery storage?+

Yes — many of our clients run solar alongside EV charging and battery storage as one integrated system for maximum savings.
