I had to do the same thing last year and my second child starts this year.
Once I knew the accommodation costs I added:
Supermarket/food costs (dependent on how catered their halls are).
Daily travel - she will be entitled to a student oyster card. Check charges (depending on her zones) on Transport for London website.
Lunch - I checked the university catering part of website and found out price of basic snack lunch as a max and a supermarket/Boots/Gregg's cheap sandwich as a minimum. Realistically I don't think they are going to take a packed lunch! My son gets hungry so I threw in the cost of a packet of crisps. Realistically £3 a day min.
Going out - not as expensive as we think. They drink cheaply. A lot but cheaply! They don't seem to go out to eat but do pick up kebabs or chips at 1am in the morning. I felt that £25 a week was tight but fair.
Toiletries etc. Girls will probably spend more than boys. My daughter will probably spend £20-£30 a term including the necessaries. I reckon my son spends £10 a term on basic cleaning products. However condoms are surprisingly expensive! (I don't want to think about how often he buys them!)
I thought I would carry on buying his clothes -which I have done - but he has spent a fair amount on required games kit (team kit etc). I have given him extra for this as needed. I will do the same for my daughter but will incorporate a basic clothing allowance in her budget. This amount will depend on individual circumstances. If she wants more money for clothes she will use babysitting money or go out less and so save elsewhere. I will buy coats and shoes etc as birthday/Christmas presents. £10.
Petty cash - coffees, laundrette (important!), newspaper (wishful thinking), photocopying, printing. £15.
Books - my son had a £400 bill as a Reading list start up cost (big expensive bio reference books) but he hasn't bought any since. He does have to pay for printing and photocopying.
Among my friends in similar London situations £90-£100 a week for those in non catered accommodation seems to be acceptable norm. £60-70 if in catered accommodation. PLUS weekly travel. The parents are picking up one off costs - travel home, games kit etc.
I know a few who are doing it on less but their children supplement their budget with regular paid work. My son is doing sciences and does not have time for a job. He works in the holidays but so far has used that money for travel. My daughter has regular babysitting and supplements her clothes and Wagamama dominated social life. As they get established at uni they will have to learn that this income may have to fund more than travel and clothes!
Hope these figures help. It is an expensive business!
