Is Termination Notice Required?

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.


This is why having expert guidance is so important. At SeeMore Energy, we help businesses track key contract dates, manage termination windows, and ensure that notice is served at the right time -- protecting you from costly rollover rates while keeping your options open.

With consumer spending declining and OFGEM raising their price cap, you would be forgiven for seeing February as a month where negative news was at the forefront, but in the energy markets, this was not the case.

In a year that began with falling energy prices, there were recurring catalysts that led to prices climbing steadily higher. Geopolitical uncertainty and the perennial threat of escalating conflicts meant fear would maintain a constant presence in the wholesale markets. We will look back at the key energy stories from 2024, and how the energy markets are likely to shape up in 2025. Quarter 1  The year began with cautious optimism as the UK’s gas reserve levels were healthy and prices for the Summer’24 season were in freefall. In February, prices pulled back to their lowest levels since 2021, and for the first time in a while, we identified that there was greater potential for upside risk than for further downward price movement: “ there now (exists) an asymmetrical element of risk should the market encounter a supply-side problem of significance. ” During February we had advised customers on flexible contracts that this was an ideal time for making purchases. March would see prices begin to ascend again as international conflict would create problems with LNG imports, and we would highlight the geopolitical risks as an area for concern moving forwards: “ fears remain and there are potential negative catalysts that could lead to prices rising further, with the main factors to watch out for being based on geopolitical unrest. “ For a business that purchases their energy in advance, this quarter was the optimal time for purchasing during 2024. In February, electricity prices for Winter’25 were down to 7.75p/Kwh, and as low as 6.05p/Kwh for Summer’25. Winter’25 ended the year with prices above 11.1p/Kwh, with Summer’25 prices exceeding 9p/Kwh. For a company that uses 500,000Kwh of electricity per month, the difference between buying at the February low point compared to today’s prices would represent a yearly saving of over £200,000.
