Do you live at home at the moment?
My bills are around £170 a month for water/gas/elec/internet and phone and council tax based on a single person. I live pretty frugally as I'm not at home much. I dont have a tv (license is something to think about). This is in a pretty well insulated and modern 3 bed terraced house.
I found theres alot of shit you end up buying that your mum usually gets (air fresheners, clothes horse, tea towels, cleaning bits and pieces, hoover, tin foil etc) that you don't even think about, but someone has to buy.
I have only rented uni houses in the past and they're set up slightly differently to 'normal' rentals. My dad owns a few rental houses and if, say, the boiler breaks, he has to sort it out. Its the landlord's responsibility to make sure everything is in order.
