Thank you Andrew, I hadn’t heard of a voltage detector stick before. You’re right about the meters not recognising BST and now I know I will adjust accordingly. However my issue is with companies not informing customers of this. Again you’re right and there is nothing to stop companies exploiting customers by not giving them this information. To my mind this is a loophole that needs to be closed. The companies know that many customers will be unaware that times do not keep up with clock changes and are therefore making money fraudulently.
Just as a follow up. I was re-reimbursed the £75 that I’d estimated I had overspent as a result of them lying by omission and I would urge anyone who has fallen foul of this scam to fight back.
