Annual usage × unit price + supplier standing charge + network charges, levies and taxes. For variable offers we use a shared PSV reference of 0.501205 €/Smc (12-month average, 2025-10/2026-09), which may differ from the contract’s index. Monthly spending is the annual estimate divided by 12, not a winter bill.

Estimates include network charges, system levies, excise and VAT. Supplier unit prices and standing charges are shown before these additions.
