Do United Kingdom passport holders need a visa to visit CG?

British (UK ordinary) passport holders need a visa to enter the Republic of the Congo (Congo-Brazzaville). There is no general eVisa or visa-on-arrival for tourists; you must apply in advance at the Embassy of the Republic of the Congo in London before you travel. As of May 2026, the UK government (GOV.UK travel advice) confirms that British citizens must hold a visa to enter the Republic of the Congo and should apply before travelling by contacting the Republic of the Congo Embassy in the UK. The Republic of the Congo (Congo-Brazzaville, country code CG) is distinct from the neighbouring Democratic Republic of the Congo (DRC, CD), which is rolling out a separate eVisa; CG does not currently operate a general tourist eVisa or visa-on-arrival channel, so the conservative and correct verdict is visa-required. The Embassy of the Republic of the Congo in London issues short-stay tourist visas: a single-entry 15-day visa costs around GBP 85, with multiple-entry options up to 6 months at higher fees, typically processed in 3-5 working days. A yellow fever vaccination certificate is mandatory for all travellers, and a polio vaccination certificate is also required at border control. Passports should be valid for at least 6 months and carry blank pages, with proof of onward travel and accommodation (hotel booking or notarised invitation letter). The Republic of the Congo is in Central Africa and is not part of the Schengen area, so the Schengen 90/180 rule and ETIAS do not apply.
