Great British Energy Community Fund
The Great British Energy Community Fund (formerly the Community Energy Fund) provides grants for community-led clean energy projects, including rooftop solar, battery storage, EV chargers, and rural heat networks, with funding administered regionally through Local Net Zero Hubs. It offers up to £40,000 for feasibility studies and up to £100,000 for development-phase support, helping prepare projects to become investment-ready. The scheme prioritises community ownership and local benefit, supporting councils, charities, co‑ops, and social enterprises across England looking to deliver clean energy.

Annual Investment Allowance (AIA)
The Annual Investment Allowance (AIA) isn’t a grant, but it can significantly reduce the cost of going solar by allowing businesses to deduct the full value of their solar PV investment from taxable profits. This can lead to a substantial corporation tax saving, effectively funding part of the system. It’s one of the most straightforward and generous ways to support commercial solar investment through the tax system.

There are several funding sources available to help UK businesses go solar. Here's where to look:
1. National Government Schemes
The UK government supports solar through a range of national programmes focused on clean energy, net zero, and industrial decarbonisation. These are especially active in the public sector, education, and industrial estates.
2. Local Authority & Regional Funding
Many local councils and regional bodies offer dedicated grants for solar and wider energy efficiency upgrades. These schemes are often time-limited and tailored to support local business growth and sustainability.
3. Utility & Industry-Led Programmes
Some energy companies and trade bodies offer funding, rebates, or co-investment options to encourage renewable adoption among commercial customers.
4. Innovative Green Finance Funds
Emerging financial models blend grants, low-interest loans, and revenue-sharing agreements, especially for SMEs, commercial landlords, and multi-tenant sites. These make solar more accessible without high upfront costs.
Understanding the grant process helps you plan your solar investment with confidence:
1. Remote Solar Assessment
The first step is a remote solar feasibility assessment. This evaluates whether your site qualifies based on factors like roof size, energy usage, and estimated solar generation potential.
2. Grant Amounts & Structure
Grants are typically offered as capital contributions, covering 10–40% of the total installation cost. The exact amount and structure depend on the scheme and your business location.
3. Application Process
You'll need to submit:
Support is usually available from grant administrators or delivery partners like Absolar to guide you through the process.
4. Grant Award & Installation
If approved, the grant is either paid directly to you or reimbursed after installation. In most cases, you'll pay the installer upfront, then claim back the grant based on proof of completion.
5. Compliance & Reporting
After installation, you’ll need to confirm project delivery through photos, invoices, and commissioning certificates. Some schemes require ongoing energy performance reporting to track carbon savings.
