Let's see:
Rent
Depending on your contract you will also have to paid maintenance fees for the common areas in the apartment building / flat.
Council Tax - depends on the tax band your apartment is in normally paid in 10 instalments over the year (April - Jan)
Gas / Electricity - With the increases over the last couple of years this has become pretty expensive especially if you have a lot of gadgets and can fluctuate a lot over the year based on weather patterns.
Water - Depends if your flat / apartment has it's own meter if not you'll normally pay a flat monthly fee based on the rating of your building which generally ends up being somewhat more expensive than if you were metered however it's a fixed price
TV license - 135 or so pounds for the year due in January
TV / Internet / Phone - Very depending on your provider / area what this will cost and of course the type you want. Do keep in mind that there is also an usage component there although if you get a VOIP account with a major voip provider you can get free calls to landlines for not too much a year (10 euro for 120 days, 300 minutes a week and you keep your 10 euro for credit to calls that aren't free, 1 pound for a voip-in number so you can be called yourself). Although a voip phone or gateway (if not provided by your ISP) is going to be a relatively large initial outlay. (> 50 quid)
Food / Drink / other consumables (bin lines / cling film / spices etc) - Depends very much on if you (can) properly cook or not as if you have to buy ready meals all week or takeaway your shopping will be very expensive.
Cleaning materials -
You'll need furniture and all the kitchen stuff as well (pots pans / cutlery / cutting boards etc)
Refrigerator
Washing machine + powder / conditioner
Microwave
Kettle
Toaster
Iron / Ironing board / Cloth horse
Sofa
Table
TV / Radio
Printer paper / ink or toner (not cheap when you have to buy it, does last a while)
Plus you have to put some money aside for when one of these things breaks that you can buy a new one or get it repaired.
Contents insurance (depends on your level of cover but without a no-claim it ain't going to be cheap although it's recommendable seeing as anything happening to your surrounding apartments could affect you)
All your subscriptions
Possibly a window cleaner every x weeks
Travel expenses (they do add up) which are very dependent on your mode of transport
Clothing
Depending on your area - rubbish collection fees.
That's all I can think of the top of my head. I'll have a little look at the list later and compare it to the bills and see if anything else pops up.
Update:
Do keep in mind that when you are renting they will most likely want a deposit of some sort. The amount varies somewhat but normally it's somewhere between 1.5 to 2 months rent also you normally pay your rent in advance which means that before you even more in you'll have to fork out over 2.5 to 3x the amount of your monthly rent. Presuming you don't break the place you'll (hopefully) get your deposit back.
There are also contract fees which although aren't the end of the world can add up to 35 to 60 pounds or so depending on who you're renting from. If your contract runs out you'll either have to renew (which comes with a renewal fee) or work on the basis of a rolling contract, however, you don't have a lot of security in that situation.
Update 2:
Don't forget that if you are moving and your family doesn't own a big car / trailer etc you will probably have to rent a large van for a day (or 2). Normally rental companies only rent these things to people over the age of 24 (for insurance). Depending on the size of the van this can easily run into 50 - 130 pounds excluding fuel etc.
Also you will probably need to buy some boxes / tape etc to move all your stuff in as well which adds another couple for 10ers
