Breaking down your business gas questions

How can businesses reduce greenhouse gas emissions?

There are several strategies businesses can take to lower their greenhouse gas emissions:
• Switch to energy suppliers offering renewable or lower-carbon gas options
• Improve insulation and heating efficiency in your premises
• Schedule regular maintenance for gas equipment
• Monitor usage with smart meters
• Invest in carbon offsetting initiatives
Reducing your emissions not only lowers environmental impact but can also boost brand reputation and reduce costs over time.

Does gas count as a business expense?

Yes, business gas is typically considered a legitimate business expense. If the gas is used solely for business operations, such as heating your premises or powering industrial processes, you can deduct it as an allowable expense when calculating your taxable profits. Keep records of all bills and payments to support any claims.

How much is business gas per kWh?

As of 2025, business gas prices in the UK typically range from 4p to 10p per kWh, depending on your usage level, region, and contract type. Larger businesses often benefit from lower unit rates due to higher consumption. Fixed-rate deals can offer more stability, while variable rates might fluctuate with market conditions. Unlike the domestic market, there’s no price cap on commercial energy, which means variable rates can often be significantly higher. We can help you benchmark your current rate and find better options.

What is the VAT rate on business gas and electricity?

The standard VAT rate for business gas and electricity in the UK is 20%. However, if your business qualifies as a "low energy user" (using less than 145 kWh of electricity or 5,000 kWh of gas per year), you may be eligible for a reduced rate of 5%. Certain business sectors also qualify for a reduced rate of VAT, so speak to one of our trusted consultants to find out if your business is eligible for the reduced rate of VAT and Climate Change Levy exemption.
