Name change on Indian passport and T1G visa from within UK?

Hello

After marriage, my wife has not yet changed her surname. Meanwhile, she has got her Tier 1 General Dependent visa on her maternal surname.

If we apply for a new passport at Indian consulate in London, and get a new passport booklet with new name and surname, do we also need to contact UKBA to change name and surname on visa?

Also, visa will be in old passport with maternal name/surname. I am guessing just carrying all passports together should be enough.

Any help appreciated!

Thanks.
