Why is my smart meter showing odd readings after switching supplier?

First‑generation devices can lose smart mode or mix up registers after a switch or comms issue. If that happens, reads may fail and estimates take over. Submit photos of the actual meter, not the in-home display, and ask your supplier to validate registers and correct your account.

What if I miss the 31 December meter reading deadline?

You can still submit a reading as soon as possible. Your supplier may use estimates to split December and January usage if no actual is on file at year end. A prompt read helps correct that split. Keep photo proof and ask for backdated adjustments if needed.

How does the 1 January Ofgem price cap change affect me?

The cap sets unit rates and standing charges for typical use, and it changes from 1 January. If your supplier estimates usage across the period, a late or missing read can push more units into the new rates. An accurate 31 December read creates a clean cut-off.

What should investors watch in this Octopus Energy story?

Focus on complaint volumes, Ombudsman cases, smart read success rates, and customer churn. Also monitor refund levels and credit balance movements, which affect working capital. Strong data validation and fast corrections reduce compensation exposure and protect trust during price cap resets.
