Many visitors need a UK Standard Visitor visa to attend a trade fair on business; some nationalities are visa-exempt for short business visits. Check your nationality against the official GOV.UK guidance before travel.
Processing: Varies by nationality; apply several weeks before travel.
Business visits to the UK are covered by the Standard Visitor route. GOV.UK publishes the permitted business activities and the full list of visa-required and visa-exempt nationalities. Some travellers also need UK Electronic Travel Authorisation (ETA) or must meet other entry requirements, so allow time to confirm eligibility.
