Thames Water takes payments from customers early in direct debit blunder

How to check if you're affected

We first became aware of the issue after one of the MoneySavingExpert.com team who is also a Thames Water customer – MSE James – was sent an email from the company admitting to the mistake.

Thames Water says it's now emailed all affected customers who have given the firm an email address. But if it doesn't have your email address, it is still possible you may have been affected and haven't been told.

If in doubt, check your bank account – if your direct debit's normally taken on the 14th, it may have been taken on the 13th instead. Thames Water won't say how many customers in total have been affected by the issue, though it's understood to be less than 30,000. 

You can get bank charges refunded – but you'll need to ask

If the unexpected payment means you were charged fees by your bank, for example because it pushed you into an overdraft, Thames Water says it will cover the cost.

If you need to claim a refund, you should send an email to customer.help@thameswater.co.uk with:

• A subject line of 'Bank charges'
• Your Thames Water account number
• Evidence of the bank charges, eg, a bank statement or letter from your bank
• Whether you'd prefer the refund to be paid as credit on your Thames Water account or cash into your bank account

Make sure you keep any paperwork or statements showing charges, such as overdraft fees. And if you haven't yet incurred bank charges but are worried the direct debit payment being taken early may mean you are in due course, keep checking your account.
