Green Savings: Unravelling the Tax Benefits of Installing Solar Panels on Your Business Building in the UK

In the pursuit of sustainable practices and cost savings, many businesses in the UK are turning to solar energy. Apart from reducing carbon emissions and energy costs, installing solar panels on your business building can unlock several tax benefits and incentives. In this blog, we will explore the tax advantages associated with solar panel installations in the UK, helping businesses harness the power of the sun while maximising their financial returns.

Enhanced Capital Allowances (ECAs):

One of the key tax benefits for businesses in the UK is the Enhanced Capital Allowances (ECAs) scheme. Under this initiative, businesses can claim 100% first-year capital allowances on investments in energy-saving equipment, including solar panels. This means that the full cost of the solar panel installation can be deducted from taxable profits in the year of purchase, reducing the overall tax liability. ECAs encourage businesses to invest in renewable energy technologies and accelerate the payback period for solar panel installations.

Business Rates Relief:

In the UK, installing solar panels on your business building can also lead to business rates relief. The government has introduced various schemes to incentivise businesses to adopt renewable energy. Currently, properties with installed solar panels with a capacity below 50 kW are eligible for 100% relief from business rates. This relief can significantly reduce the financial burden associated with property taxes, making solar panel investments even more attractive for businesses.

Feed-in Tariffs (FiTs) and Smart Export Guarantee (SEG):

While the Feed-in Tariff (FiT) scheme has closed for new solar panel installations, businesses can still benefit from the Smart Export Guarantee (SEG). The SEG requires energy suppliers to offer payments to businesses for any excess electricity generated by their solar panels and exported to the grid. This means that businesses can earn income from the surplus energy they produce, further enhancing the financial viability of solar panel installations. It’s worth noting that the SEG rates may vary depending on the energy supplier, so businesses should compare offers to secure the most favourable terms.

Value Added Tax (VAT) Savings:

When installing solar panels on your business building, you may also be eligible for reduced VAT rates. Currently, the installation of energy-saving materials, including solar panels, is subject to a reduced VAT rate of 5% instead of the standard rate of 20%. This reduction in VAT can lead to substantial cost savings, making solar panel installations more financially viable for businesses.

Carbon Reduction Commitment (CRC) Energy Efficiency Scheme:

For large businesses with high energy consumption, the Carbon Reduction Commitment (CRC) Energy Efficiency Scheme provides further tax incentives. By implementing energy-saving measures, such as solar panel installations, businesses can reduce their carbon emissions and potentially lower their CRC obligations. This scheme rewards businesses that take proactive steps to improve energy efficiency and reduce their environmental impact, providing long-term financial benefits.

Consultation with Tax Advisors:

To ensure that you fully leverage the available tax benefits and incentives, it is advisable to consult with tax advisors or professionals specialising in renewable energy tax schemes. They can provide tailored advice based on your business’s specific circumstances and help you navigate the complex tax landscape, ensuring compliance with regulations and maximising the financial advantages of solar panel installations.


Installing solar panels on your business building in the UK not only contributes to a sustainable future but also offers significant tax benefits and incentives. The Enhanced Capital Allowances (ECAs), business rates relief, Smart Export Guarantee (SEG), VAT savings, and the CRC Energy Efficiency Scheme are just a few examples of the tax advantages businesses can enjoy. By harnessing solar energy, businesses can reduce their tax liabilities, lower energy costs, and demonstrate their commitment to environmental stewardship.
