Smart meters: missing reads, registers & fixes (UK)

Smart meters should reduce estimated bills, but problems happen: missing reads, wrong register setups (e.g., Economy 7), or communication issues.

Quick checks

• Check if your bill uses actual readings or estimates.
• If you have Economy 7, confirm day/night registers are billed correctly.
• Take meter photos regularly — they win disputes.

Why it happens

• Smart meter not communicating properly (WAN/HAN issues).
• Register setup incorrect after switch or installation.
• Supplier systems still estimating despite smart meter.

What to do next

1. Submit an up‑to‑date reading (even for smart meters) and keep confirmation.
2. Ask supplier to confirm register configuration (especially Economy 7).
3. If billed wrong repeatedly, follow dispute steps and escalate if needed.

FAQs

Why is my bill estimated with a smart meter?

If the meter isn’t communicating reliably, suppliers may estimate. You can submit readings and request a fix.

What are meter registers?

Tap to expand

Registers are separate counters for usage (e.g., day/night on Economy 7). If swapped, bills look wrong.

Do meter photos help?

Yes. Timestamped photos are strong evidence when challenging incorrect readings or billing periods.
