Is Termination Notice Required?
When it comes to business gas and electricity contracts, one of the most common areas of confusion is termination notice. Many British businesses are unaware that failing to act within the correct notice window can result in being locked into expensive rollover contracts or missing opportunities to secure better rates.
When is notice required?
In most fixed-term energy contracts, suppliers require formal termination notice to be given ahead of the contract end date. This notice period typically ranges from 30 to 120 days, depending on the supplier and the terms agreed at the outset. If termination notice is not submitted within this window, your contract may automatically renew -- often onto higher rates that are far less competitive than those available in the market.
When agreeing to switch to a new supplier, they often will provide the notice on your behalf, but it should be confirmed with the new supplier whether they will do this.
Does providing termination notice mean we may be at risk of having no supply?
Providing termination notice does not mean your supply will stop. It simply gives you the flexibility to leave your current supplier at the end of the contract and explore alternative options. In fact, many businesses issue termination notice as a standard part of their energy management strategy, keeping their options open while monitoring the market for the best time to secure a new deal.
However, timing is critical. Serving notice too late can restrict your ability to switch suppliers, while serving it too early -- without a clear procurement strategy -- can expose your business to market volatility if prices rise before you lock in a new contract.
When is termination notice not required?
It’s also important to understand that there are situations where termination notice is not required. For example, some modern flexible contracts or supplier-specific agreements do not include automatic rollover clauses, meaning notice may not be necessary. In other cases, if you are planning to pursue a “Blend and Extend” strategy, serving termination notice too early could complicate negotiations with your existing supplier.
Additionally, if your business is mid-tender or actively negotiating new terms, submitting termination notice prematurely can sometimes reduce your leverage or create unnecessary administrative complications. Each contract is different, and the correct approach depends on your current terms, market conditions, and overall procurement strategy.
