Top 7 grants for solar panels for businesses

Switching to renewable energy, like solar power, is one of the most effective ways for businesses to reduce their environmental impact, cut energy costs, and boost their corporate image. Plus, it shows your customers and stakeholders that you’re serious about sustainability.

Of course, while solar panels offer long-term savings, the upfront costs can feel daunting. Thankfully, there are plenty of grants and funding schemes available in the UK to ease the financial burden.

We’ve pulled together the top 7 grants for solar panels for businesses, so you can make a smart, sustainable choice without blowing the budget.

1. Smart Export Guarantee (SEG)

The Smart Export Guarantee (SEG) is a UK government-backed initiative that allows businesses and households generating renewable electricity — including solar power — to earn money by exporting excess energy back to the National Grid. It effectively replaces the now-defunct Feed-in Tariff (FiT) and is overseen by Ofgem.

Who It’s For

  • UK businesses of any size with renewable energy systems up to 5MW capacity (including solar PV).
  • Systems must be installed by an MCS-certified installer.
  • Must have a smart meter or export meter capable of recording half-hourly export data.

Funding/Benefit

  • There is no set rate — licensed energy suppliers set their own export tariffs.
  • Rates vary but typically range from 1p to 15p per kWh depending on the supplier.
  • Payments are made for every kWh of electricity exported to the grid.

Geographic Scope

  • Available UK-wide (England, Wales, Scotland, and Northern Ireland).

How to Apply

  1. Install an MCS-certified solar panel system.
  2. Choose a SEG-licensed energy supplier (even if different from your current energy provider).
  3. Submit an application directly with the supplier, along with:
    • Proof of installation (MCS certificate)
    • Export meter details
    • Proof of identity and business address

Pros

  • Generates income from unused energy.
  • Encourages efficient solar use and smart energy planning.
  • Easy to access with the right setup.

Cons

  • Tariffs can be low or vary between suppliers.
  • Doesn’t help with upfront installation costs — it’s a paybackscheme, not a grant.
  • Requires a smart/export meter and formal accreditation.
