With energy bills increasing from October 1, when the Energy Price Guarantee comes into effect, an urgent scam warning has been issued to energy customers.
The National Fraud Intelligence Bureau (NFIB) has warned people to keep an eye out for fake emails from Ofgem claiming to be about energy rebates.
Between the end of August and the start of September, more than 1,500 fraudulent emails of this variety were reported via the Suspicious Email Reporting Service (SERS).
