## In short

One supplier bills both gas and electricity — sometimes with a dual-fuel discount, but splitting fuels across suppliers can still be cheaper.

Compare dual-fuel against separate electricity and gas quotes.

Single-fuel households need only electricity — do not pay for gas you do not use.

One bill simplifies admin but is not always lowest cost.
