Energy was last better‑than‑free: yesterday Next

On the Agile Octopus tariff, customers get paid to use electricity when there’s too much in the grid.

That’s cheaper than Octopus Energy paying to store it.

The price changes every half-hour.

VAT cut to 0%. VAT on home electricity is 0% from this date until 31 Mar 2027. It was 5%, not the usual 20%, so this saves only about 1.3p on a typical price, which normal day-to-day changes can hide.
