Miss your energy renewal date by even a day, and your supplier doesn’t pause your service. It quietly moves you onto its most expensive tariff and most owners don’t notice until the bill lands.
According to a 2026 survey of published supplier schedules, out-of-contract electricity rates range from roughly 33p to 45p per kWh, well above the 22–30p typical of a properly fixed contract.
For a busy café, salon or care home, that gap can mean thousands of pounds a year for doing nothing differently except letting a renewal date slip past.
Deemed Rates vs Out-of-Contract Rates
These two terms get used interchangeably, but they’re not quite the same:
- Deemed rates apply when you take on a premises and use energy without ever agreeing a contract, a common trap for new tenants
- Out-of-contract rates apply when your fixed term runs out and nothing new gets signed
- Both are set at the supplier’s discretion, with no price cap protecting business customers the way there is for households
Either way, you’re paying the supplier’s default price and default pricing is built to reward inertia, not loyalty.
How Quickly It Bites
There’s no grace period. The higher rate applies from the day your fixed term ends, and keeps applying every day until a new contract starts.
Energy is genuinely complex to manage: renewal windows vary by supplier, notice periods differ, and most SME owners are juggling this alongside running the business. That complexity, not carelessness, is usually why renewal dates get missed.
According to TDH’s own research, roughly 8 in 10 UK businesses are unknowingly overpaying on energy, and a missed renewal is one of the most common reasons why.
Clawing the Position Back
The good news: out-of-contract doesn’t mean locked-in.
- You can typically exit an out-of-contract arrangement with 28 days’ notice and no early termination charge
- Check your latest bill for the words “deemed,” “variable,” “out-of-contract,” or a contract end date that’s blank or already passed
- Once you’ve confirmed your position, get live market quotes compared against your actual usage, the difference between suppliers on the same profile is significant

What This Means for Hospitality and Retail SMEs
Renewal dates are easy to lose track of when energy isn’t your day job. But every week on a default rate is a week paid at the top of the market.
A simple calendar check, or a platform that tracks it for you, is the difference between catching this early and discovering it three quarters late.
