UK energy supplier contracts often impose fees for switching to a competing supplier, locking customers into higher prices. Many consumers remain with suppliers offering poor rates because early termination fees make switching financially disadvantageous. Ofgem regulations govern energy supplier conduct, but enforcement is reactive, and many contracts contain terms that technically comply with regulations yet are unfair in practice. Under the Domestic Gas and Electricity (Tariff Cap) Act 2018, Ofgem sets price caps and switching standards. Fixed-rate contracts are common, and while early termination fees are permitted, they must reflect reasonable estimates of the supplier's actual costs. Understanding switching terms before signing helps consumers compare the true cost of staying versus switching.
What is a Switching Restrictions and Early Termination Fees?
An energy supplier contract is an agreement for gas and/or electricity supply at a set rate for a fixed term (typically 12-24 months). Fixed-rate contracts lock in a price, while variable-rate contracts follow market prices. Contracts specify: the tariff (price per unit), standing charges, payment terms, contract duration, and early termination conditions. Most contracts allow switching suppliers at any time, but many charge early termination fees if you switch before the contract ends. These fees are meant to compensate the supplier for costs incurred (hedging, customer acquisition) but are often inflated. Ofgem guidance states early termination fees must reflect actual reasonable costs, not punitive charges.
Red flags to watch for
Ofgem expects early termination fees to vary based on remaining contract term. Fixed fees regardless of when you exit are likely excessive and potentially unenforceable.
While not always prohibited, percentage-based fees that multiply over time can become excessive. For example, 10% of 18 months remaining can equal £300+ on higher tariffs.
Ofgem requires transparency. Unexplained fees without calculation methodology are suspicious and may indicate unjustified charges.
While suppliers can manage switching operationally, contractual blocks on switching are unfair. Consumers should have the statutory right to switch at all times.
Ofgem requires 30 days' notice for material changes, with right to cancel. Changes with insufficient notice may breach fair contract principles.
Contracts must show the tariff, unit rate, standing charge, and how they compare to the price cap. Absence of clear pricing information suggests potential deception.
Your legal rights
Ofgem (the Office of Gas and Electricity Markets) regulates energy suppliers under the Gas Act 1986 and Electricity Act 1989. The Domestic Gas and Electricity (Tariff Cap) Act 2018 sets maximum prices Ofgem caps. The Consumer Rights Act 2015 applies to energy contracts, prohibiting unfair contract terms. Ofgem's Standards of Conduct require fair treatment and transparency. Suppliers must provide 30 days' notice of material changes and allow exit. Early termination fees must reflect actual reasonable costs. Consumers can switch suppliers in as little as five working days and cannot be charged for switching. Complaints to Ofgem or the Energy Ombudsman can result in enforcement action.
