Rollover Contracts — What They Are and How to Escape Them

A rollover is what happens when your fixed business energy period ends and, instead of you signing something new, the supplier keeps you on a fresh contract term—often at rates printed in small print weeks earlier. It is legal when the licence conditions and your written contract allow it. It is also one of the fastest ways for a profitable shop or workshop to pay 26p when the competitive market for their profile was nearer 23–24p.

Next step: If you use under about 50,000 kWh a year, you can get a quote in under 90 seconds online — fast, no obligation. Larger supply, half-hourly metering, or prefer chat? Use the contact page.

Key takeaways

  • Rollover is not the same as an out-of-contract deemed rate—both sting, but the paperwork path and notice rules differ.
  • Microbusinesses get tighter end-of-contract letters from licensed suppliers under Ofgem rules; file them next to your VAT certificate.
  • Calendar your termination notice window separately from the contract end date—missing it is how another twelve months locks in.
  • If you are mid-switch, read how to switch so a partial overlap does not look like acceptance.
  • Model total annual cost: a standing charge at 380p/day with a 27.5p unit rate can beat a 25.8p rate at 620p/day when usage is only 18 MWh.

Plain definition for a busy owner

Your site keeps buying power or gas from the same retailer, the clock resets to a new end date, and the price list attached to that automatic extension is usually worse than what proactive buyers negotiated the same week. Suppliers such as E.ON Next Business, British Gas Lite, SSE Business Energy, TotalEnergies Business and dozens of smaller retailers all publish different rollover formulas; the common theme is inertia pricing.

Picture a tyre garage outside Newport. Their March renewal email sat in a shared inbox while the MOT lane blew up. By April they were on a 14-month rollover at roughly 29p/kWh while a broker board for their 42,000 kWh profile showed fixes around 25–26p once pass-through was stripped back. The garage lost about £1,250 on electricity alone before anyone compared—entirely avoidable with a diary note.

How rollover differs from deemed or default supply

Deemed supply typically refers to continuing consumption without a formal contract—think a landlord gap or a tenant who never signed. Rollover is a contract engine: you already have terms, and silence triggers the next chapter. Bills may still label the product “default” in clunky portals; trust the PDF schedule, not the colour of the button.

Out-of-contract rates published online can sit even higher than rollover—sometimes mid-thirties p/kWh on electricity when wholesale stress returns—so finance teams should not assume “anything beats rollover.” Work the maths each time.

Microbusiness protections you can actually use

If you meet the microbusiness thresholds (roughly up to 100,000 kWh electricity or 293,000 kWh gas a year, or few employees with turnover under €2m—confirm the precise test on Ofgem or in our microbusiness rules guide), suppliers must provide clearer renewal information. That does not guarantee a bargain, but it gives you dated evidence if a verbal renewal pitch contradicts the letter.

Cooling-off and information standards matter when someone pressures you on the phone while you are serving customers. Ask them to email the principal terms and hang up.

Escape checklist before you ring the call centre

Work top to bottom; skip a step and you repeat the rollover cycle.

  • Export the contract PDF and highlight the clause that describes renewal, termination channel (portal vs post), and notice period in days.
  • Confirm whether you are still inside the window to reject the rollover—timestamp any emails.
  • Pull twelve billed months of kWh; rollovers bite harder on lean users because standing charge share rises.
  • Challenge exit fees only after reading early termination guidance—sometimes paying breakage beats another bad year.

Timeline discipline that actually sticks

Pair this page with what happens when your contract expires and set three reminders: T-120 days (read contract), T-60 days (request quotes), T-30 days (decision). Energy teams call it boring; finance directors call it EBITDA protection.
