Financial Benefits
Tax Incentives &
Capital Allowances
Commercial solar is one of the most tax-efficient capital investments a UK business can make. The government actively incentivises renewable energy adoption through generous capital allowances that significantly reduce the net cost of your solar system.
For many businesses, the combination of tax relief, energy savings and export income means commercial solar pays for itself within 3–5 years — then generates free electricity for the next 20+ years.
Annual Investment Allowance (AIA)
Deduct 100% of your solar installation cost from taxable profits in the year of purchase — up to £1 million. For a business paying 25% corporation tax, a £50,000 solar system effectively costs just £37,500 after tax relief.
Example: £80,000 Commercial Solar System
Asset Depreciation & Balance Sheet
Solar PV is treated as a tangible fixed asset on your balance sheet. Beyond the AIA first-year allowance, ongoing capital allowances apply through Writing Down Allowances (WDA) at 6% on the special rate pool. Solar assets appreciate in value over time as energy prices rise, making them a strong long-term investment that improves your company's asset position.
0% VAT on Commercial Solar
Since April 2022, solar PV installations on residential and charitable properties benefit from 0% VAT. For VAT-registered businesses installing on commercial premises, the standard 20% VAT is reclaimable through your VAT return — so the effective VAT cost is zero either way.
SECR — Streamlined Energy & Carbon Reporting
UK companies meeting two of these criteria must report under SECR: 250+ employees, £36m+ turnover, or £18m+ balance sheet. Solar PV directly reduces your reported Scope 2 emissions (purchased electricity), demonstrating genuine carbon reduction rather than just offsets.
ESOS — Energy Savings Opportunity Scheme
Large enterprises (250+ employees or £44m+ turnover) must audit energy use every 4 years under ESOS. Solar PV is a recommended energy efficiency measure that auditors highlight — and it demonstrates you're acting on audit recommendations, not just reporting.
Net Zero Commitments & ESG Reporting
Investors, clients and supply chains increasingly require verified carbon reduction data. Solar PV provides measurable, auditable reductions in your Scope 1 and Scope 2 emissions. For businesses making Net Zero pledges, on-site generation is the most credible action you can take.
Carbon Certificates & Green Credentials
Every kWh of solar energy you generate comes with provable carbon savings. We provide generation data and CO2 displacement figures for your annual reports, ESG submissions, tender documents, and marketing materials. Solar-powered businesses win more contracts.
Compliance & ESG
Carbon Reduction
& Reporting
UK businesses face growing pressure to measure, report and reduce their carbon emissions. Regulatory requirements like SECR and ESOS are mandatory for qualifying companies — and voluntary reporting is increasingly expected by investors, clients and supply chains.
Solar PV is the most visible, measurable and credible carbon reduction action a business can take. Unlike carbon offsets or pledges, on-site solar generation provides verifiable, real-time emission reductions that stand up to audit scrutiny.
We provide comprehensive generation data and CO2 displacement figures for your compliance reporting — making it easy to demonstrate genuine progress towards your carbon targets.
