FTB here, first time paying a mortgage (and not renting) and first time paying bills (and not splitting with housemates or it being included with rent). Also first time having a smart meter.
Bills came up to over £300 for gas and about £100 for electric. Water is paid quarterly. This is what we naturally needed to use (2 of us - DH and I) pre smart meter.
Conscious of looking at the meter now and spending up to £10/day (totally gas and electric). Is this about right?
