Thanks for the info about the price rise. What will the new tariff actually be in August?(price per unit and daily standing charge) You only gave the increase to the monthly bill in your message.
@judithandmichael There should be an attachment on that email. The unit prices are in there.
Also if you go to your account dashboard https://account.bulb.co.uk/dashboard and select “Account & tariff info” at the bottom of the page you should see a message (mine was dated 11 June) Variable Price Change Email, this provides details of the new tariff.
