Business Energy FAQS
1. What is business energy?
Business energy refers to the gas and electricity supplied to commercial premises and unlike domestic energy, business energy tariffs are tailored to a company’s usage, contract length, and size. Businesses can choose from fixed, variable, or green energy tariffs.
2. How is business energy different from domestic energy?
Business energy contracts are usually:
Longer term (1–5 years) Individually negotiated based on consumption Single-fuel only (businesses cannot bundle gas and electricity) Exempt from the cooling-off period that domestic users get
So, this makes choosing the right supplier and tariff especially important.
3. How much does business energy cost in the UK?
Costs vary depending on your business size, location, and usage, and as of 2025, average business energy rates are:
Electricity : 25–35p per kWh Gas : 7–12p per kWh
Standing charges typically range from 20 p– 7 0p per day but l arge businesses may negotiate bespoke rates.
4. Can I switch my business energy supplier?
Yes! Businesses can switch once their contract enters the renewal window , usually a few months before expiry. Switching can cut costs significantly , especially if you are on out-of-contract rates.
5. What types of business energy tariffs are available?
Fixed-rate tariffs – unit prices are locked for the duration of your contract. Variable-rate tariffs – rates fluctuate with wholesale market prices. Deemed/out-of-contract tariffs – usually the most expensive; avoid if possible. Green tariffs – supply backed by renewable energy sources such as wind, solar, or biomass.
6. How long are business energy contracts?
Most contracts run for 1–5 years . Shorter deals provide flexibility, while longer ones may secure better rates but reduce flexibility if prices fall.
7. What is the Climate Change Levy (CCL)?
The CCL is a government tax applied to business gas and electricity bills to encourage energy efficiency and reduce carbon emissions, so some sectors, like charities and low-energy users, may qualify for exemptions or reduced rates.
8. Can businesses choose renewable energy?
Yes!!. Many suppliers offer 100% renewable electricity tariffs and green gas options. Switching to renewables helps businesses lower their carbon footprint and demonstrate sustainability credentials.
9. What support is available for businesses struggling with energy costs?
Schemes such as Energy Bill Relief (for specific sectors) and tailored supplier payment plans can provide assi stance . Businesses can also reduce bills through energy audits, efficiency upgrades, and demand management solutions .
10. How can I reduce my business energy bills?
Compare suppliers regularly Invest in energy-efficient equipment and lighting Monitor usage with smart meters Encourage staff energy-saving behaviour Consider renewable energy sources, such as installing sola r panels
