Work Injury leading to disability

Hi - Just need some advice
My wife had an accident at work last year at work and after a lot of to and fro by us and our lawyers, the company ahs accepted liability. My wife hurt her hip and over the period, this has turned into CRPS which has no cure. She has to use crutches to walk and will be in a wheel chair in the near future. I have to do everything in the house now as she cannot do much at all. She has also been awarded Disability living allowance. I may have to leave my job to care for her if the condition gets any worse. We also have 3 children who she cannot really look after any more and our social life is now totally non existent. My wife is only 35 years old!! What sort of compensation figure should we expect as the plan was that our youngest child would start secondary school this year and my wife would have got a full time job and we would then have cleared our mortgage within 10 years or so. If I have to give up work, we could even lose our house. Please advice! Thanks
