I spend money on my rent, electricity, water, heating, etc.. so I need to take all of that into account.. on top of groceries, household products, and misc stuff.. so I guess if I divide that up monthly it will come to about.. 35-40 pounds per day. Not including rent and utilities it is probably about 8 pounds a day when I factor in food, travel, and misc things for the house. I rarely go out shopping for myself but I like to make sure my home is comfortable and I am eating well, but I am factoring in some spending money in this amount. (I like to keep on top of where all my money is going and my finances.)
