How to avoid out-of-contract business energy rates — a practical playbook

What 'out of contract' actually means

When your fixed-term business energy contract ends and you haven't agreed a new one, your supplier moves you to their default variable — commonly called out-of-contract (OOC) or 'deemed' rates. These are the most expensive rates that supplier offers, and they usually stay that way until you actively agree a new contract.

Typical OOC unit rates run 40-80% higher than a fresh negotiated fixed contract. On a 40,000 kWh electricity account that gap alone can add thousands of pounds a year with no additional value in return.

Why so many businesses end up there

It's rarely because owners don't care — it's because energy renewals fall between the cracks. The finance team assumes ops has it; ops assumes the incumbent supplier will 'sort it out'; the supplier sends a renewal quote at the same rate you're already paying and the moment passes.

The fix is systems, not effort. Once you set up renewal tracking, the actual decision each year takes 20 minutes.

Know your renewal window

Ofgem rules require suppliers to publish contract end dates and remove auto-renewal restrictions for micro-businesses. In practice, most suppliers accept quotes and future-dated contracts from six months before your end date — and some as much as 12 months.

That renewal window is your opportunity to shop the market. Miss it, and you either pay the incumbent's renewal offer (rarely the best) or roll to OOC.

Build a renewal tracker

A simple tracker beats a complex one. At minimum record:

• Supplier name and account number
• MPAN or MPRN
• Contract start and end dates
• Unit rate, standing charge and annual usage
• Renewal window open date (typically end date minus 6 months)

Use a broker as an insurance policy

Whole-of-panel brokers track renewal dates as a service and will approach you in your window automatically. For most SMEs this is the simplest way to guarantee you never sleepwalk onto OOC rates — the service is free (commission is factored into the tariff) and gives you a second pair of eyes on your contract calendar.

Already on OOC? Move today, not tomorrow

If you're currently on OOC rates, don't wait for a 'better time'. Every day on those rates costs more than the negotiated alternative. Get a fresh quote now and switch as soon as your supplier will allow — most switches complete within 4-6 weeks and are fully automatic with no interruption to your supply.
