How does an energy switching or savings scam work?
Energy switching scams collect sign-up fees or personal data under the pretence of switching your utility to a cheaper tariff, without actually completing any switch or using a legitimate comparison service.

Explanation
Scammers cold-call homeowners or visit doorstep, claiming to be from an energy savings programme or comparison service. They offer to review your current tariff and switch you to a cheaper deal. The presentation is persuasive and includes real-looking charts or printed comparisons. An upfront admin fee or 'switching fee' is requested — no legitimate energy comparison service charges this.
Some operations do submit a switch, but to a more expensive tariff where the fraudster receives a commission. Others collect bank direct-debit details and make unauthorised payments. The most basic variant simply takes the fee and delivers nothing.
Door-to-door energy sales have historically been a high-fraud area even among nominally legitimate operations, because aggressive sales techniques and misleading comparisons have been used by registered companies as well as outright fraudsters. The regulatory environment has tightened in many countries, but the approach continues.
Data-harvesting variants use a fake comparison site that collects your energy usage details, account number, and bank details under the pretence of finding you a better deal. This information is used for identity fraud or sold to other parties.
Common red flags
- A cold caller asks for upfront payment to switch your energy tariff
- A door-to-door visitor pressures you to sign immediately without time to verify
- The comparison shown lists providers you cannot verify independently
- The visitor or caller cannot provide regulatory identification or accreditation
- Bank details are requested before any switch is formally confirmed in writing
- The offer is significantly better than any you can find on legitimate comparison sites
What to do now
- Never pay an upfront fee to switch energy — legitimate switching services are free to consumers
- Use your national energy regulator's approved comparison service rather than cold-caller recommendations
- Ask any door-to-door caller for their company's regulatory reference and verify it before engaging
- If bank details were given, contact your bank immediately
- Report to your energy regulator and national consumer protection authority
- You have the right to cancel most door-to-door sales within a cooling-off period — check your country's rules
Frequently asked questions
Are all doorstep energy sales fraudulent?
No. Legitimate energy companies do use doorstep sales in some markets, but they are regulated, cannot charge switching fees, and must provide a cancellation period. The fraud indicators are urgency, upfront fees, and inability to verify credentials.
What is the cooling-off period for doorstep sales?
In the EU and UK it is 14 days. In the US it varies by state but is commonly three days for doorstep contracts. You can cancel without penalty during this period.
Can a scammer actually switch my energy supply without my consent?
Slamming — unauthorised switching — does occur. Monitor your energy bills for confirmation of any switch you did not initiate, and contact your supplier immediately if you identify one.
