Hi, I moved into a property last year. It has a Worcester 30CDI conventional. I recently had a smart meter fitted on the 5th December. From the 5th Dec to today, 4th Jan I have used 317 m3 gas. The boiler is the only consumer of gas within the house, hob is induction, and ovens are electric. Does this seem excessive? Is there anything i should have checked. Any advice appreciated.
