Energy Prepayment Meter Top-Up Scam

Energy prepayment meter top-up scams target households with pay-as-you-go electricity or gas meters by offering discounted top-up codes sold outside official channels. The codes are either stolen from legitimate customers, generated fraudulently, or entirely fabricated — meaning the credit never appears on the buyer's meter, or appears briefly before being reversed.

Prepayment meters are disproportionately used by lower-income households, who are also more motivated by the apparent saving offered by a discounted code. The scam exploits this directly, positioning the offer as a money-saving tip in community groups, social media, and messaging apps.

The harm is twofold. First, the buyer pays for codes that provide no usable energy credit. Second, if the codes were stolen from another customer's account, the buyer may inadvertently use energy paid for by someone else — and the credit may later be reversed when the theft is detected, leaving the buyer without heating, cooking, or power at any time of day or night.

Some variants extend to selling 'top-up cards' or account credentials that allow one customer to use the credit purchased by another, which constitutes energy theft regardless of whether the buyer knew the origin of the codes.

Scammers advertise discounted prepayment codes in community Facebook groups, WhatsApp groups, local Nextdoor communities, and social media. The offer is typically framed as a money-saving opportunity available 'through contacts' in the energy industry or as codes left over from another customer's account.

The buyer pays a discounted amount — perhaps half the face value of the credit — by bank transfer, PayPal, or cash. They receive a code by message. They enter it into their prepayment meter. In some cases the code works initially; in others it fails immediately or the credit disappears after a short period when the fraudulent origin is detected and the credit is reversed.

In the credential-theft variant, the buyer is given login details for another customer's energy account and instructed to use the credit in that account to top up their own meter. This transfers credit fraudulently and constitutes theft even if the buyer was not aware the account belonged to a third party.

After the transaction, the seller is typically uncontactable and the community post has been deleted.

Prepayment meter customers are often managing tight budgets and the appeal of a significant discount on energy credit is genuine. The community setting in which the offer is usually made — a local group where neighbours share tips — adds credibility and social proof.

Energy top-up codes look like legitimate product codes and buyers have no immediate way to know whether a code is genuine, stolen, or fraudulent before entering it. The short window between payment and discovery — sometimes a matter of hours — means the money is gone before the problem is apparent.

Purchase prepayment top-up credit only through official channels: the energy provider's app, website, official top-up shops, or authorised retailers. No legitimate discount on prepayment credit is available through private sellers, social media, or community groups.

If a code fails when entered or credit disappears shortly after appearing, contact your energy provider immediately. They can investigate whether the code was legitimate and whether your account has been affected by fraudulent activity.

Do not purchase codes described as 'leftover', 'spare', or 'obtained through contacts in the energy industry'. These descriptions are consistent with stolen or fraudulently generated codes rather than any legitimate discount mechanism.
