Rhose,
The key financial requirement under the new rules is completely different to those under the old rules.
UKBA now puts the emphasis almost completely on the 6 months gross income of the sponsor immediately prior to visa application.
There is no account whatsoever upon the financial circumstances of the applicant.
There is really no review of monthly outgoings, affordability analysis or savings.
Actually, savings will only be counted towards the financial requirement when there is any shortfall in gross income and then it's only those savings above £16000
Your husband will need to show 6 months pay slips and corresponding 6 months bank statement showing the salary payments. This will be in addition to the confirmations from the employer.
Hope that helps to settle your concerns
