Knowing when your business energy contract ends helps you avoid expensive out-of-contract rates and gives you time to compare better deals. Start by checking your latest energy bill or online account; the contract end date or notice period is often listed near your tariff name or unit rates. If you can’t find it, look at your original contract documents or welcome email from your supplier, where the fixed term and renewal date should be clearly stated. Suppliers usually send a renewal notice 42–90 days before the contract expires. This is a great time to compare renewal prices with other suppliers.  Use a comparison tool that searches leading providers in one go.

You can also contact your supplier directly by phone, email, or live chat and ask for your contract end date and any required notice period. Make a note of this date in your calendar and set reminders a few months in advance so you have plenty of time to review options, negotiate, or switch to a more competitive business energy tariff.

For microbusinesses, suppliers are usually required to show key contract information clearly on bills and renewal letters, including when your current deal ends and what prices you’ll pay if you do nothing. Check for any automatic rollover terms that might move you onto a higher-priced tariff. If you use a broker or consultant, they may also hold copies of your contracts and can confirm your end dates and renewal windows.

Keep all your energy documents in one place and consider creating a simple contract log that lists each site, supplier, tariff, and end date. This small step can prevent missed deadlines, reduce costs, and give you more control over your business energy strategy year after year.

Failing to act means you may be rolled over onto higher "out-of-contract" rates, which can be 30-50% more expensive.
