Can I afford to live on my own?

Hi all

I earn £1037 a month. I'm looking at a £400 a month house. This leaves £637 for the rest of my bills. I will be living completely on my own, can someone give me a rundown of the basic costs of living?

So for example I imagine it'd b £200 for food, £100 for gas+electric so that's £337 left. £33 for my phone, £50 for toileteries, £50 for my travel so that leaves £207. Then £20 for my internet, an extra £10 for other (Netflix and Minecraft Server) leaving £187 to spend on whatever I want.

Is this correct?
