No interruption to supply • Secure process • Takes minutes
In Great Britain, your energy supplier sells you gas and electricity and handles your billing and customer service. The network operators maintain the pipes and wires that deliver energy to your home. When you switch supplier, your meter and the local network don’t change, and there is no break in supply.

Fixed tariffs lock in unit rates and standing charges for a set term, often with exit fees. Variable tariffs can move up or down, usually with fewer or no exit fees.
They offer cheaper night rates and higher day rates. They suit homes that can shift usage to off-peak hours or use storage heating or hot water tanks efficiently.
