How scams that copy energy suppliers and networks 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. Ofgem warns that scammers may contact you by phone, text, email, social media or at your door, pretending to be from Ofgem or an energy company.
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 Utility Warehouse back on a number you've found yourself, such as the one on their own website or on a letter or bill from them.
