The UK has no visa-on-arrival scheme, so arrange entry clearance before travelling. Most EU, US, Canadian, Australian and Gulf nationals enter visa-free but must hold a valid Electronic Travel Authorisation (ETA, about GBP 16) obtained online before boarding. Visitors from visa-required countries need a Standard Visitor Visa (about GBP 127, typically decided in 3 weeks), which permits attending trade fairs, business meetings and contract discussions but not paid employment. British and Irish passport holders need no visa or ETA. Carry proof of accommodation, onward travel and funds; ATA carnets are accepted for temporary machinery imports.
Estimated cost: Varies by visa type and nationality (check official site).
