An Eon spokeman said: “Due to new Ofgem rules, which includes limiting the number of tariffs we can offer, the Staywarm tariff will close as current contracts come to an end.”
The rules were introduced to simplify choice. There is another tariff called Age UK deal which also offers fixed rates for a year.
“We have never told suppliers which tariffs they have to close to comply with this rule, as that is a decision for them,” an Ofgem spokesman said. Eon said they have no obligation to close any social tariff, and closing Staywarm was the company’s choice.
All affected customers will receive confirmation of this in writing from Eon, advising them to move to another tariff, but those who do not switch will be moved the company’s standard rate.
