What Does Out of Contract Mean for Business Energy?

“Out of Contract” Is One of the Most Expensive Phrases in Business Energy. Here’s Exactly What It Means — and Why It Costs So Much.

When a business energy contract expires without a replacement being in place, the business moves to what is commonly described as “out-of-contract” status. This is not an administrative technicality. It is a shift from a competitively negotiated supply arrangement to a default supply arrangement where the supplier sets the rate entirely at their discretion — typically 40–80% above what a competitive contract would deliver for the same consumption.

Understanding what “out of contract” means, how businesses end up there, and how quickly it should be resolved is essential commercial energy literacy for any UK business owner.

The Technical Definition

An energy contract is a fixed-term supply agreement between a business and a licensed energy supplier. It specifies the unit rate, standing charge, contract start date, contract end date, and the terms governing supply during the contract period.

When the contract end date passes without a new contract being agreed and executed — either a renewal with the same supplier or a new contract with a different supplier — the business has no active supply agreement. The energy continues to flow because the supplier is legally obligated to maintain supply, but the commercial terms under which it is supplied revert to the supplier’s standard out-of-contract or default tariff schedule.

This default tariff is not published in the same way as a competitive contract offer. It is set by each supplier independently and is not subject to regulatory caps for business customers. It reflects the supplier’s cost of providing unhedged spot-market supply, plus a significant commercial margin for the absence of competitive pressure.

Out-of-Contract vs Deemed Contract: The Distinction

These terms are frequently used interchangeably but have a technical difference:

Out-of-contract: A situation where the business had a formal contract that has since expired without renewal. The business and supplier had a prior contractual relationship at that premises. The supply continues at the supplier’s out-of-contract rate.

Deemed contract: A situation where no contract has ever been formally established at the premises with the current occupier — typically arising at the point a business moves into new premises. The legal basis is different (the Gas Act 1986 and Electricity Act 1989 impose supply obligations) but the commercial outcome is the same: expensive default rates set at supplier discretion.

Both situations are expensive. Both should be exited quickly. For practical purposes, both are described as “out of contract” in most business energy conversations, and the resolution process is identical.

How Businesses End Up Out of Contract

There are four common routes to out-of-contract status:

Missing the notification deadline: Business energy contracts contain notification windows — the period before contract expiry during which you must give written notice of your intention not to renew automatically. These windows run from 30 to 90 days before expiry. A business that doesn’t know the deadline, or knows it but misses it, auto-renews — and if the auto-renewal term itself then expires unmanaged, the business reaches out-of-contract status after two cycles of passive management.

Contract expiry without auto-renewal: Some contracts expire without an auto-renewal mechanism, or the auto-renewal is successfully prevented by a notice given in time, but no new contract is then arranged. The business is out of contract from the expiry date.

New premises without immediate supply arrangement: A business that moves into premises and doesn’t immediately arrange a supply contract is on deemed rates from day one of occupation. This is functionally out-of-contract status from the moment of occupation.

Supplier failure and SoLR transition: When a supplier fails, the Supplier of Last Resort (SoLR) takes over the customer book. Business customers are initially transferred on deemed/out-of-contract terms by the SoLR, who is not bound by the previous supplier’s contracted rates.

What Out-of-Contract Rates Actually Cost

Out-of-contract rates vary by supplier and are not publicly published in a standardised format. They are set to reflect the genuine cost of unhedged spot supply plus a commercial margin. Based on 20+ years of reviewing out-of-contract business energy bills, Telnergy’s experience is that OOC rates typically run:

• Electricity: 40–70% above the competitive contracted rate available at the same time
• Gas: 30–60% above competitive contracted rates

For a business spending £60,000 per year on energy at a contracted rate, a move to out-of-contract pricing at 50% premium means £90,000 per year — an additional £30,000 annually with no corresponding change in consumption or service.

The longer a business remains out of contract, the greater the accumulated overpayment. A business that is out of contract for 12 months, with £60,000 annual energy spend and a 50% OOC premium, overpays by £30,000 before a new contract is arranged. This is a recoverable cost in the sense that a new contract will end the overpayment — but the £30,000 already spent is not recoverable.

How Quickly Can Out-of-Contract Status Be Resolved?

Resolving out-of-contract status is straightforward and can be achieved quickly. The process:

1. Identify the current supplier and obtain your MPAN/MPRN
2. Provide consumption data (annual kWh from the last bill or an estimated figure)
3. Obtain competitive quotes — a broker with access to 15+ suppliers can produce a comparison in 24–48 hours
4. Agree a new contract — documentation can be completed within hours
5. New contract start date — typically achievable within 1–4 weeks

The gap between identifying out-of-contract status and having a new contract executing is rarely more than a week for a straightforward single-site business. Every day of delay costs money at the OOC premium rate.

Can Out-of-Contract Rates Be Challenged?

Out-of-contract rates are legally valid. The supplier is entitled to charge their published default tariff to an uncontracted supply. Challenging the principle of OOC rates — “I didn’t agree to this rate” — is not a successful approach.

However, two specific challenges can be pursued:

Inadequate notification: If the supplier failed to provide adequate notification of the contract expiry — as required by Ofgem’s rules for micro-business customers — this can be grounds for disputing the OOC rate retrospectively. For larger business customers, the contract terms govern and supplier notification requirements are less stringent.

Rates significantly above the published schedule: If the rate applied is higher than the supplier’s own published out-of-contract schedule, this is a billing error and is challengeable. Suppliers cannot charge above their own published OOC tariff.
