When does your energy contract end?

Business energy contracts typically last 1-3 years. Switching at renewal can save 20-40%. Out-of-contract rates are significantly higher.

Potential saving: £478/year

Saving opportunities

  • Check whether a renewable tariff with REGO certificates can remove Climate Change Levy.
  • Review lighting, heating controls, refrigeration, and overnight equipment use.

How is business energy different from domestic energy?

Business energy is not protected by the Ofgem domestic price cap. Businesses negotiate rates directly with suppliers, usually on 1-3 year fixed contracts. Business electricity is usually subject to 20% VAT and most businesses also pay the Climate Change Levy.

What is the Climate Change Levy?

The Climate Change Levy is a tax on energy supplied to business and public sector users. It is charged per kWh for electricity and gas, although qualifying renewable electricity tariffs with REGO certificates can be exempt.

When should I renew my business energy contract?

Start comparing deals around 6 months before your contract end date. If you do not renew or switch, many suppliers move businesses onto expensive deemed or out-of-contract rates.

What does this mean?

This calculator is designed to help you understand the likely number before you make a decision or start an application.

Your result should be checked against official UK guidance, especially if your circumstances include dependants, exemptions, prior leave, or a complex immigration history.

Treat the figure as a planning tool rather than legal advice. Where the answer affects an application deadline or major payment, speak to an authorised adviser.
