Average Gas Bill in the UK
Under the current Ofgem price cap, a typical UK household using 9,500 kWh of gas a year pays around £802 annually, or roughly £67 a month — though most households pay more in winter and less in summer.
Gas accounts for around 60–70% of total energy use in most UK homes with central heating. Standing charges add roughly £106/year before any units are used.
