You do not choose your gas band. It is decided by how much gas you burn over a year, and that band sets the price you pay every month.
Bands group homes and businesses by how much gas they get through in twelve months. A flat that only uses gas for hot water sits in a different band from a house that heats every room through the winter. That is why two bills that look alike can carry different prices. It is not a mistake, it is the band.
At Reazziona every band has its own fixed price. You know what your energy costs before the month starts, and you are not exposed to whichever index happens to be climbing. The price stays where it is.
Checking your band is straightforward. It appears on your gas bill, next to your contract details and the annual consumption your distributor has on record. With that figure to hand you can compare properly.
And if you would rather not hunt through the small print, our gas page lists the bands and their prices in plain sight. We would rather you understood the tariff before you signed it.
