Most international delegates need either a UK Electronic Travel Authorisation (ETA) or a Standard Visitor Visa before boarding. Visa-exempt nationals — including US, Canadian, Australian, New Zealand, EU/EEA, Japanese and GCC passport holders — must hold an approved ETA (GBP 16, valid two years) for business visits of up to six months. Nationals of India, China, South Africa, Nigeria and Turkey must apply for a Standard Visitor Visa (GBP 127, typically decided within three weeks), which covers attending conferences, business meetings and contract negotiations but not paid employment. Apply at least six weeks before departure and carry your invitation letter, employer letter and delegate confirmation.
Estimated cost: Varies by visa type and nationality (check official site).
Processing: Varies by nationality; apply several weeks before travel.
Valid for two years or until passport expiry and permits multiple entries of up to six months each. Linked electronically to the passport — no visa vignette is issued. Conference attendance, fact-finding and contract negotiation are permitted; paid employment and selling directly to the public are not. Carry your invitation letter and delegate confirmation.
