We have had this same situation as my Mum passed away in September. Phone all the utilities (though I'm sure you have). We have disconnected the phone; water board have made a note and said they are not worried about a bit of usage, so no problem there. Electric is still on, but we have switched off everything we can (eg oven clock, microwave etc). We have left the heating on one hour in the morning, one hour in the evening and set the thermostat at 16C...though hopefully with the weather warming up, it won't come on much. Phone the local council about council tax...this should now be zero as no one is living in the house. Phone the house insurance...they should reduce the premium as no one is living in the house, but normally for the insurance, someone has to 'check' the house at least once a week...next door neighbour?
