I am so sorry, I have mislead you. Yes there is a GBP 200 adjustment available. According to the Telegraph it operates as follows.
'How does it work?
All workers have a personal allowance for tax purposes. This is the amount of money an individual can earn in a year before they must pay tax. It is currently £9,440 and will rise to £10,000 in April. The Government has not said what level the personal allowance will rise to in 2015/16, but some experts predict it will reach £10,500.
Married couples and civil partners where one person earns less than the personal allowance will be allowed to transfer up to £1,000 of their unused allowance to their partner, reducing their tax bill.
For example, if one person earns £5,000 and their partner earns £20,000, the lower earner can transfer £1,000 of their unused allowance to the higher earner. The higher earner can take home an additional £1,000 tax-free, so thanks to 20pc relief they will pay £200 less tax over the year.'
I am so sorry not to have told you of this change.
