Hi Scottycan
I just attended an assessment day and was told by recruiters pay for a new junior is around £10,500, which goes up to £11,000 ish after one year. On top of this you can expect to earn approx £6,000 a year in allowances and duty free commission. I've found this thread which may be of use to you

Hope it doesn't put you off, and good luck with your application!
