A billing error at ScottishPower led a vulnerable pensioner to pay £8,413 after a letter warned of credit damage. The company said an incorrect 2022 meter reading was used, refunded £9,000, and added new checks.
A power company made a big math mistake and sent a man a huge bill by accident. He got scared and paid it right away, like handing over money because a shop note looked official. Later, the company fixed the error and gave the money back.
Analysis
What happened
Richard Palmer, 76, received a ScottishPower bill in March demanding immediate payment of £8,413 and warning that a credit default could be recorded if he did not pay. The letter’s urgency caused panic, and he transferred the money on the spot, using about half of his savings.
Why the bill was wrong
ScottishPower later said the charge came from an incorrect meter reading from 2022 being used to calculate his bill. Palmer’s daughter, Anne, had already noticed suspicious charges, including a bill being taken twice in November, and had complained to the company.
What the company did
ScottishPower said it refunded a total of £9,000, including the duplicate payment, and apologised for the mistake and the delay in resolving it. The company said it had introduced enhanced checks and added vulnerability markers to Palmer’s account. Anne said the family accepted a £1,000 goodwill payment after an earlier £500 offer was rejected.
Wider context
The case arrived in the same week that the energy price cap in Great Britain was set to rise by 13% from 1 July. Consumer groups said the Palmer case was unusually severe, and pointed to the need for stronger safeguards when suppliers handle bills for older or vulnerable people. Martin Lewis also noted that many customers on standard tariffs may be able to avoid the cap rise by moving to a fixed deal if it is cheaper for their usage.
Key points
- ScottishPower wrongly billed Richard Palmer £8,413 and warned that non-payment could affect his credit file.
- Palmer paid the bill in panic, despite a previous letter saying his yearly gas and electricity costs would be about £922.
- The company said an incorrect 2022 meter reading caused the error and that it refunded £9,000.
- ScottishPower said it has introduced extra checks and marked Palmer’s account as vulnerable.
- The case came as Great Britain’s energy price cap was set to rise by 13% from 1 July.
ScottishPower says it has added enhanced checks and vulnerability markers, which could reduce the chance of a similar mistake happening again. If those safeguards work, vulnerable customers may be less likely to face sudden, panic-inducing bills.
If billing checks are still weak, other customers could face the same kind of frightening error and feel forced to pay before the issue is reviewed. The rising energy price cap also means households already under pressure may be less able to absorb billing shocks or recover quickly from them.
