What is energy switching?

In short: Energy switching means moving your gas and electricity supply from one supplier to another — or to a new tariff with the same supplier — to cut bills or get better service. Since the energy crisis, fewer small suppliers operate, but you can still compare Ofgem-capped standard tariffs and fixed deals through comparison sites or directly.

Switching involves choosing a new supplier or tariff and signing up; the new supplier handles the transfer. There is no change to your pipes, wires or meter — only who bills you and at what rate. The switch typically completes within five working days after a 14-day cooling-off period for most domestic contracts.
Your current supplier may charge an exit fee if you leave a fixed deal early — check terms before switching. Since July 2023, the Ofgem price cap limits what suppliers can charge per unit on standard variable tariffs; it is reviewed quarterly. Fixed tariffs may beat or lag the cap depending on market conditions when you switch.
Smart meters, outstanding debt and prepayment meters can complicate switches. If you owe money, some suppliers will not take you until it is cleared or may require a payment plan. Tenants can switch if they pay the energy bill directly; if bills are included in rent, the landlord chooses the supplier.
Use Ofgem-accredited comparison tools or the supplier's own quote with your annual kWh usage from a bill. After switching, submit a meter reading on the go-live date to avoid estimated bills. If something goes wrong, the Energy Ombudsman handles complaints against participating suppliers.
