A Meter Mix-Up Left a UK Homeowner Paying More After British Gas Fixed Its Own Error

2 min read · 2026-07-22

A wiring mix-up inside a new-build UK housing estate meant one homeowner's energy use was billed to a neighbor for months, and correcting it pushed their tariff up 19%.

19%Tariff increase after the meter mix-up was corrected

The facts

  • 1A homeowner in a new-build UK estate found their electricity meter had been wrongly linked to a neighbor's supply by British Gas.
  • 2New housing developments often connect several homes' meters before individual addresses are fully verified, which can confuse supplier billing systems.
  • 3After British Gas corrected the mix-up, the homeowner's tariff rose by 19% compared with the rate they were paying before the fix.
  • 4The homeowner says they are now being charged for usage that should have been billed under the mixed-up account, despite reporting the error themselves.
  • 5Ofgem, the UK energy regulator, requires suppliers to fix billing mistakes and can order refunds, but untangling meter mix-ups can take months while customers keep paying.

Why it matters

Energy bills already strain household budgets, and this case shows a supplier's own metering mistake can still leave the customer paying more, even after it is caught and corrected.
