If you would like to travel and stay in the United Kingdom for up to six months, but will not be working you should apply for and obtain a visit visa for the United Kingdom, which is a short stay temporary visa.

If you are coming to the United Kingdom on a business trip or for medical treatment, this is the visa that you should apply for as well. While the United Kingdom does offer business visitor visas, the visit visa is typically better for business people that will only be in the United Kingdom for a short period. However, you are not allowed to enter into any type of employment while in the country and can only attend meetings or auditing work while on the visit visa.
The British visit visa is attractive to most business people because it is a quick and easy visa to obtain and does not have quite the formalities and work permit approval process as the business visitor visa does. However, if staying more than six months, the business visitor visa is better as it offers multiple entries and a valid period of up to two years.
