How do I find my business energy contract end date?
Look at the front page of a recent bill — suppliers must show the contract end date and notice period there for micro-businesses, and most show it for everyone. Failing that: your renewal letter, your original contract paperwork, or your online account. If none of those surface it, phone your supplier and ask — they must tell you. It is the single most valuable number in business energy: miss it and you are rolled onto rates you never negotiated.

Where it hides, in order
- A recent bill — usually the front page or the “about your contract” box. Mandatory on micro-business bills, together with the termination notice deadline.
- Your renewal letter — sent typically 60 days or more before the end date. If one has arrived, the date is in it (and the letter itself is worth beating: send it to us).
- The original contract or confirmation email — start date plus term length gives you the end date.
- Your online account with the supplier, under contract or tariff details.
- Ask the supplier. A two-minute call: “What is my contract end date, and what termination notice do you require?” Note the answer, the date and who told you.
Why this one number matters so much
- Renewal pricing opens 6–12 months out. Knowing the date early means choosing your moment in the market instead of taking whatever is left in the final week — see When can I switch supplier?.
- Notice windows expire before the end date. Many contracts require termination notice weeks or months in advance; miss it and the rollover clause fires.
- Letting it lapse entirely lands you on deemed or out-of-contract rates — commonly 35–45p+/kWh in 2026 against fixed deals at 22–30p: Deemed & out-of-contract rates.
Found it? Do these three things
- Diarise the end date and the notice deadline — two separate entries.
- Set a review point 6 months out to test the market while every option is still open.
- Or hand the whole job to us, free: tell us the date — or email a bill to info@utilitiesms.co.uk with “diarise my end date” and we will find it, log it, watch the market for your window, and serve the termination notice when the time comes. You will hear from us at exactly the right moment and never roll over again.
Cannot find it anywhere?
Send whatever paperwork you do have to the free bill audit. With a bill (or just your MPAN/MPRN and a letter of authority) we can identify the supply, confirm the contractual position with the supplier and take it from there.
Common questions
Is the supplier obliged to tell me my contract end date?
Yes — ask and they must confirm it. For micro-businesses it must also be printed on bills along with the notice deadline. Keep a note of the call: date, time and the figure given.
What is the difference between the end date and the notice deadline?
The end date is when the contract term finishes. The notice deadline — often 30 to 90 days earlier — is the last day you can tell the supplier you are leaving. Miss the deadline and many contracts renew automatically even though the end date has not arrived.
How early can I agree my next contract?
Most suppliers will price contracts starting up to 12 months ahead. Agreeing early does not end your current deal sooner — the new contract simply starts the day the old one finishes.
What if I have already missed the notice window?
You may be caught by a rollover clause. Serve written notice immediately for the earliest exit the contract allows, and read our guide to cancelling a rollover contract for the realistic exit routes.
Does the reminder service cost anything?
No. Diarising end dates and serving notices is part of how we work — it costs you nothing, and it means your renewal is priced across the whole market with time to spare rather than in a panic.
