Wrong meter reading on an energy bill (UK): proof that wins

If your bill looks wrong, your goal is simple: replace the supplier’s numbers with evidence. This page shows what to photograph, what to request, and a copy‑paste rebill email.

2 photos win disputes 10‑minute evidence pack Copy‑paste request

Step 1 — Confirm the basics

Billing dates
Wrong date range = wrong total. Check start/end dates and days billed.
Unit rate & standing charge
Rates can change mid‑period. Confirm p/kWh + p/day and effective dates.
Rate change checks
Estimated vs actual
If the bill is “E/Estimated”, fix that first — it’s the #1 cause.
Estimated bill steps

Bill map (what must match)

Dates → reads → rates → total.

Billing period Start date • End date • Days billed Meter reads Opening • Closing • Actual vs Estimated Rates Unit rate (p/kWh) + Standing charge (p/day) + Effective dates Total Usage (kWh) × unit rate + standing charge × days
If any block doesn’t match your evidence, you have a clean reason to request a rebill.

Common mistake types + what wins

Mistake type How you spot it What to request Evidence that wins
Estimated used as actual Bill shows “E/Estimated”, or reads don’t match your photos. Reading history + confirm estimated vs actual for each read. Timestamped meter photos near bill dates.
Wrong register (Economy 7) Day/night swapped, or one register jumps unrealistically. Register mapping confirmation (R1/R2) + tariff confirmation. Photos showing both registers + serial number.
Digits entered wrong Huge spike (often one digit off). How the read was captured (customer/agent/auto) + audit trail. Read photo + proof you submitted correct read (screenshot).
Wrong meter / serial mismatch Bill serial number ≠ your meter serial number. Confirm serial on account + correction process/site visit. Clear serial number photo + statement screenshot.
Wrong dates / overlap Two bills cover same days, or period length is off. Explain date ranges and days billed calculation. Both statements + short timeline.

Step 2 — Evidence pack (10 minutes)

1) Two meter photos

Opening + closing (or nearest dates). Make digits readable.

2) Serial number photo

A serial mismatch is hard to argue with.

3) Proof of submissions

Screenshots of reads you submitted via app/web/email.

4) Simple timeline

Date → what happened → reference number.
