I have a valid (multiple entry) business visit visa to the UK on my old passport. I have recently obtained a new passport as I ran out of pages on my old passport. The purpose of my visit is still for business and there are no change in personal details on my new passport. There is however a change in address on the new passport. Incidentally it is the same address that I filled out for my UK visa application while answering the query "WHAT IS YOUR PERMANENT RESIDENTIAL ADDRESS AND CONTACT DETAILS?"
In light of the above, can I still travel to the UK by carrying both the old and new passports? Or, will I be required to either transfer the visa or make a fresh application for my new passport. Thanks.
