❓ Questions

Should I pay a bill I dispute?

If you can, pay the part you agree with and dispute the rest in writing. That protects you best.

Can the supplier estimate my use?

Yes, if no reading was available. You can always send a real reading and ask for a correction.

How far back can they bill me?

The limits differ per country. Ask the energy regulator if you get a large back-bill.
