There was a General Election in Britain in 1918. All those away from their place of residence (including all men in the army) were listed on Absent Voters Lists. These usually recorded the man's regiment, number and rank at the time, as well as his home address. The lists are not held centrally and are not 100% in existence. They are held at a variety of County Records Offices or local history sections of main libraries of the area where the man lived in 1918. Some are held at the British Library too. If all you know is the soldier's name but are reasonably certain you know where he lived, this is not a bad place to search.
