EDF has unveiled a one‑year fixed‑price electricity deal priced at an average £1,689 per household for the coming year. The offer, which is marketed as the cheapest fixed tariff among the big suppliers, expires today at 4 pm and is open to both existing and new customers.

EDF’s £1,689 annual fixed tariff deadline 4 pm today

The new tariff locks in an average annual cost of £1,689, slightly above the current price‑cap level of £1,641, according to the EDF announcement. The company stresses that the rate provides bill certainty amid ongoing market volatility , but it warns that customers who consume more than the average will see higher charges than the quoted figure.

Ofgem’s price‑cap decision due 27 May adds uncertainty

Regulator Ofgem is set to confirm the next price‑cap level on 27 May, a date that could reshape the competitive landscape for fixed‑rate deals.. As the source notes, the upcoming cap will be the final figure before the regulator’s formal confirmation, meaning households are making a decision before the market’s next official benchmark.

Cheapest fixed offers from smaller rivals Outfox, Fuse and Ecotricity

While EDF promotes its new tariff as the lowest among the major suppliers, the report points out that smaller provders such as Outfox Energy, Fuse Energy and Ecotricity have consistently undercut the big players on fixed‑price contracts. These firms often target price‑sensitive consumers with rates that sit below the major‑supplier averages, creating a competitive pressure that could force EDF to adjust its pricing in future rounds.

Potential bill rise if usage exceeds the quoted amount

EDF’s marketing material clarifies that the £1,689 figure is an average estimate; households that draw more electricity will incur additional costs beyond the advertised price. This caveat is crucial for larger families or homes with electric heating, where consumption can easily surpass the baseline used to calculate the average.

Will households exceed the quoted usage?

The source does not provide data on how many customers are likely to go over the average consumption level, leaving a key uncertainty for anyone considering the switch.. without clear usage thresholds, consumers must estimate their own demand, which could lead to unexpected bill spikes if the fixed rate proves insufficient.
