How to top up your electricity prepayment meter (not smart)
Once you put your key back into your meter, you'll see the credit topped up.
It's illegal to sell prepayment credit on the doorstep, but fraudsters posing as EDF might knock on your door.
Please don't buy from them, as it puts you at risk of losing money. Anyone caught using illegal credit will end up paying twice. Once to the doorstop seller, and again to the energy supplier for any energy used.
