Agreed, a travel visa should do it, but check here to be sure - India Visa Information - UK - Home Page.
Think about applying soon tho - mine took a good few weeks to arrive earlier this month.
We did The World's End, London Road on Saturday - incredible.
One 18-hour smoked beef brisket burrito and one 16-hour pulled pork and chorizo quesadilla later, we were in heaven. 9/10.
