Adopting renewable energy for your business is a great way to reduce its carbon emissions, save money on your bills and boost your sustainability credentials.
Here you will learn what kind of sustainable energy solutions are available for businesses, the advantages of adopting, and where to get expert advice on this.
What renewable energy solutions are available for businesses?
As the UK pushes towards its Net Zero targets, many businesses are looking beyond standard fixed-rate energy contracts to see how they can future-proof their operations with renewable energy. Generally, there are two ways to go green: you can either "buy" it through a specific energy-efficient tariff or "make" it by installing your own infrastructure.
1. Green energy tariffs
The simplest way to switch to greener energy is by choosing a renewable plan. These are often backed by REGO (Renewable Energy Guarantees of Origin) certificates.
This scheme ensures that for every megawatt-hour (MWh) of electricity your business consumes, the supplier has sourced the same amount from a renewable source, such as a wind farm or solar park.
It’s a good idea to speak to an independent energy adviser before you move forward with any plans to switch to a green energy deal. The right adviser can help you access every green deal on the market and can compare them all to help you find the right tariff.
2. On-site generation
For firms with the capital to invest, installing your own renewable tech can lower long-term overheads and provide protection against market volatility. Popular solutions include:
-
Solar PV Panels: These convert sunlight into electricity. They are the most common choice for UK SMEs because they can be easily installed on warehouse or office roofs. With the Smart Export Guarantee (SEG), you can even sell excess power back to the grid.
-
Heat Pumps (Air or Ground Source): These work like a refrigerator in reverse, extracting heat from the air or ground to warm your premises. They are far more efficient than traditional gas boilers and can drastically reduce your "Scope 1" direct emissions.
-
Wind Turbines: While less common in urban areas, small-scale turbines are a highly effective solution for rural businesses or those with large amounts of land.
-
Biomass Systems: These involve burning organic materials (like wood pellets) to produce heat. This is often a viable alternative for industrial businesses that require a constant, high-temperature heat source.
Benefits of adopting renewable energy
Moving to renewable business energy isn't just about corporate social responsibility (CSR); it’s a strategic financial move that could help your business save money in the long run.
-
Tax Incentives: Businesses can often claim capital allowances on the installation of energy-saving technology, allowing you to deduct the cost from your taxable profits.
-
Energy Independence: Generating your own power shields your business from the "price spikes" seen in the global gas market, making your annual budgeting far more predictable.
-
Better Finance Rates: Many banks now offer "Green Finance" options, providing lower interest rates for loans used specifically to fund sustainable business upgrades.
If you aren’t sure which solution fits your premises, we recommend a business energy audit. An expert adviser can assess your current usage and pinpoint whether a simple tariff switch or a full solar installation would provide the best return on investment for your firm.
Renewable energy grants for UK businesses
The initial cost of installing renewable technology can be a significant barrier for many UK firms. There are, however, several government-backed schemes and regional grants designed to ease the financial burden and accelerate the transition to low-carbon operations.
Unlike standard business loans, these grants typically don’t need to be repaid, though they often require "match funding" - meaning the business covers a portion of the project costs.
1. The Boiler Upgrade Scheme (BUS)
While widely known for domestic use, the Boiler Upgrade Scheme is also open to small business premises. This provides a fixed grant of £7,500 to help cover the cost of replacing fossil fuel heating systems with air source or ground source heat pumps. It’s a straightforward way for SMEs to modernise their heating infrastructure with a significant upfront discount.
2. Regional Low Carbon Grants
Much of the funding for business renewables is distributed at a local level through Local Enterprise Partnerships (LEPs) or local councils. These are often targeted at SMEs and can cover:
-
Energy Efficiency Audits: Fully funded professional reviews of your energy use.
-
Capital Grants: Funding for solar panels, LED lighting, or insulation. These typically range from £1,000 to £25,000, depending on your location and the projected carbon savings.
Note: As these schemes are regional (such as the 'Clean Growth' funds in the North or 'Green Business' grants in the Midlands), you should check with your local authority to see what is currently active in your postcode.
3. Industrial Energy Transformation Fund (IETF)
For larger businesses or those in energy-intensive industries (like manufacturing or data centers), the IETF provides substantial funding. This grant is specifically designed for high-energy users to invest in deep decarbonisation and energy efficiency projects that would otherwise be too expensive to justify.
4. Tax Incentives: The "Super-Deduction" Successor
While not a direct grant, the Full Expensing tax break is one of the most powerful financial tools for UK businesses. It allows companies to deduct 100% of the cost of qualifying plant and machinery - including many renewable energy installations - from their taxable profits in the year of purchase. For every £1 million a business invests in green tech, they could potentially cut their tax bill by up to £250,000.
5. Smart Export Guarantee (SEG)
While technically a subsidy rather than a grant, the SEG is a vital part of the financial puzzle. It requires energy suppliers to pay you for every unit of renewable electricity you generate but don't use. By "selling back" your excess solar or wind power to the grid, you create a secondary revenue stream that helps pay off the initial installation cost faster.
How to switch to renewable energy sources
The process should begin with a free, no-obligation energy health check for your business, conducted by an independent energy adviser. During the process, they will carry out analysis into your carbon footprint and energy costs to explore where improvements can be made.
Your adviser will grant you access to a dashboard with all of the data you need on it and interpret this information to offer guidance on whether switching to a greener energy tariff or exploring sustainable on-site energy generation is in your best interest.
After conducting an analysis of your energy consumption and carbon output, your adviser will offer guidance on the following:
-
Switching to a green energy tariff, if it’s in your best interest
-
Sourcing the best sustainable energy solution for your business
-
Whether adopting electric vehicles is in your firm’s best interest
-
Whether you qualify for any sustainable energy grants or schemes

FAQs
The main drawback is often the upfront cost of infrastructure; while green energy saves money long-term, installing solar panels or heat pumps requires significant initial capital.
Additionally, some businesses may find on-site generation variable - for instance, solar output drops on cloudy days or at night - which is why most firms remain connected to the grid or invest in battery storage. Finally, the regional nature of grants means that the level of financial support available can vary significantly depending on your business's postcode.
