I am confused a little I want to attend a UK like a tourist but my visa type is C-Visit-Business. I read a lot of information but can't understand can I go to UK or can't.
Yes you can! But keep in mind some stuffs:
- Print the flight tickets, specially for two ways because they can ask for it;
- Print the hotel booking or whatever you gonna stay and keep in mind that if you gonna stay for 10 days you will need 10 days booked;
- Buy some pounds before you go, they may ask how much you have with you.
Sometimes they also ask about what itinerary you are going to do, what kind of places you would like to visit and so on. Be natural.
Nice reference, original source: https://www.gov.uk/standard-visitor-visa/overview
If you have a UK C-Visit-Business visa it means you applied prior to 24 April 2015. On that date the C-Visit-Business was abolished.
In order to manage the transition, Parliament approved the plan of having all existing C-Visit-Business visas automatically convert to Standard Visit visas. It wouldn't make sense to suddenly cancel everyone's visa, would it?
There's some really good links here: Travelling on Business visa to UK for tourism purposes
So yes, you can use your existing business visit visa for tourism or any other permitted activity.
And there's more information in the canonical.
