Visa & Entry Requirements for the UK

The UK has one of the world's most complete public transport networks, so you rarely need a car to get between its cities. Here is how trains, coaches, the Underground, taxis and driving actually work — and what each option really costs.

Trains: The Fastest Way Between Cities

The National Rail network links every major city, and it's by far the quickest way to travel long distances. London to Edinburgh takes around 4.5 hours, London to Manchester about 2 hours, and London to Bath just over 1.5 hours. The catch is pricing: Advance tickets, released around 8-12 weeks ahead, can cost a fraction of a walk-up fare on the same route, while turning up on the day for an intercity journey can be genuinely expensive. Booking through the operator's own site or an app such as Trainline, and travelling outside the 6:30-9:30am / 4:30-7pm weekday peaks, is the easiest way to save money. Splitting a long journey into separate tickets for different legs can also cut the price, even though you stay on the same train.

Coaches: The Budget-Friendly Option

National Express and Megabus connect most towns and cities for a fraction of the rail fare, especially if booked well in advance. The trade-off is time — a coach from London to Edinburgh takes roughly 9-10 hours versus 4.5 by train. Coaches are a solid choice for budget travellers with flexible schedules, or for routes with no direct train.

The London Underground & City Transport

Inside London, the Tube, buses, the Overground and the DLR run on the same pay-as-you-go system. You don't need to buy an Oyster card any more — a UK or foreign contactless debit/credit card (or your phone's contactless wallet) works directly at the yellow readers and automatically caps your daily and weekly spending at the same rate as an Oyster card, so you're never overcharged for a busy day of sightseeing. Outside London, cities like Manchester, Glasgow and Edinburgh rely mainly on buses and trams, usually paid by contactless tap or a local travel app.

Taxis, Uber and Ride-Hailing

London's iconic black cabs are metered, licensed, and can be hailed on the street or booked via the Free Now app; drivers famously pass "The Knowledge," an exam on London's streets. They're convenient but pricier than ride-hailing apps. Uber, Bolt and Free Now operate in London and most large UK cities and are usually the cheaper, easier option for short hops, especially late at night when public transport has stopped.

Driving in the UK: Left-Hand Side & Car Hire

The UK drives on the left-hand side of the road, and most hire cars are manual transmission — if you're not comfortable with a manual gearbox, request an automatic well in advance, as they're in shorter supply and cost more. Roundabouts (traffic circles) are everywhere and flow clockwise. Motorway speed limits are 70mph, dropping to 60mph on single carriageways and 30mph in built-up areas unless signed otherwise. Avoid driving into central London if possible: the Congestion Charge and Ultra Low Emission Zone (ULEZ) both apply on weekdays and add a daily fee for most vehicles. A car is most useful for rural regions like the Cotswolds, the Scottish Highlands or the Lake District, where train coverage thins out.

Domestic Flights

Short hops such as London to Edinburgh, Belfast or Inverness are available by air, but by the time you factor in airport transfers and check-in, the train is often just as fast city-centre to city-centre — and considerably more scenic.
