## In short

Compare business tariffs using your MPAN and MPRN meter numbers, annual kWh usage and contract end date — switching before auto-renewal avoids deemed rates. Give 30 days' notice per contract terms; the new supplier coordinates transfer and you should receive final meter reads and closing bill from the old supplier.

Business switches lack the domestic Energy Switch Guarantee branding but follow similar meter transfer mechanics — no physical pipe change, only billing transfer.

Credit checks apply — new suppliers may require deposits for young companies with thin credit files.

If in contract, early exit fees may apply — calculate net saving before breaking fixed deals. Micro-business contracts taken after Ofgem reforms may cap rollover penalties — check your principal terms.

Brokers take commission embedded in unit rates — transparent brokers disclose fees. Direct supplier quotes provide benchmark. See business energy explained.
