How scams that copy water companies work
UK Finance says criminals pose as organisations such as utility companies, claiming you must settle a fine, pay a bill or return a refund paid by mistake. Check your account through the water company’s own website or the number on your bill.
This could still be a scam call
Criminals can make their number look like a genuine one (this is called spoofing). If someone calls from this number and asks for money, bank details, a code or passwords, hang up. Then call Southern Water back on a number you've found yourself, such as the one on their own website or on a letter or bill from them.
