Avoid Npower like the plague - 1 star is far too generous for these clowns. I switched my account from Npower in November last year - it's now mid April and I'm still waiting for the refund of overpaid direct debits. £89 taken in overpayments may not be a lot to Npower but it's a lot to me. At least 4 times Customer 'services' (lol) have promised the refund is being processed. Nothing. Nothing. Nothing. Now I've just been told they are sending a cheque rather than refunding back into the bank account they sucked the money out of in the first place. So, if this cheque ever appears, it's a trip to the Bank and a 4-working-day wait for the cheque to clear. You couldn't make it up. One of the biggest mistakes I've made in recent years was to sign up with Npower - DON'T MAKE THE SAME MISTAKE I DID
