This would work out at about £7k (slightly over depending on exchange rate!). I think that even with the odd extravangance, you should be able to live very comfortably on this package. I'm a QS as well but with just over 1 year experience. My package is £45,500. I even turned down a higher offer of £52,000!

Even if your employer does not offer you your accommodation allowance upfront, you can still get a rent loan. However, it would be cheaper to get an interest free loan from your employer.
