🇬🇧 United Kingdom

May, June and September are the best months: long daylight, the countryside at its greenest, and the summer crowds either not yet arrived or gone. In June the far north of Scotland has light until well past eleven at night.

July and August are the warmest and busiest, with the Edinburgh festivals filling that city entirely in August. October to March is dark early, often grey rather than severely cold, and much cheaper; the Highlands in winter are beautiful and many rural attractions close.

Rain is possible in any month anywhere and is usually intermittent rather than a day-ender. The west (Wales, the Lake District, western Scotland and Ireland's neighbouring coast) is considerably wetter than the east.

The UK has a temperate maritime climate, moderated by the Atlantic, with no extreme seasons by continental standards: mild winters, cool summers, and frequent changeable weather.

The pattern is west-to-east. Prevailing Atlantic winds drop their rain on the western uplands, so Snowdonia, the Lake District and the western Highlands are among the wettest places in Europe while East Anglia is among the driest.

Daylight varies far more than temperature. In midwinter it is dark by four in the afternoon in northern England and Scotland; in midsummer it barely gets dark at all in the far north. This affects itinerary planning more than the weather does.

The UK now operates an Electronic Travel Authorisation (ETA). According to the official guidance, most visitors need either an ETA or a visa, depending on nationality and purpose; nationals of Europe, the United States, Australia, Canada and various other countries typically need an ETA rather than a visa.

The ETA covers travel to the UK, Jersey, Guernsey and the Isle of Man for stays of up to six months, currently costs £20, and is required for each traveller individually including infants. British and Irish passport holders and people with permission to live, work or study in the UK are exempt.

It also applies to transit where you pass through UK border control; passengers transiting airside without clearing immigration do not need one. An ETA does not guarantee entry, the decision rests with the border officer.

Apply only through the official GOV.UK service or its app. Commercial sites charge a markup for the same application. Check the current requirement for your nationality on GOV.UK before booking, as the scheme has been rolled out in stages.

Rail is the best way to move between cities and it rewards booking early: advance fares are a fraction of walk-up prices, and walk-up prices on long routes are among the highest in Europe. Railcards give a third off for those eligible and pay for themselves quickly.

Long-distance coaches are much cheaper than trains and considerably slower. Domestic flights are worth it only for Northern Ireland, the Scottish islands and the far north.

A car is genuinely useful for the Highlands, Wales, Cornwall and the national parks, where public transport is thin. Driving is on the left; rural roads are narrow with hedgerows and passing places, and single-track roads in Scotland have their own etiquette. Note that London, and a growing number of other cities, operate charging or emission zones that apply to hire cars.

In cities, contactless bank cards work directly on buses and metros in London and several other places; check locally rather than assuming.

The UK is expensive for accommodation and rail, moderate for food, and unusually generous on culture: the permanent collections of the national museums in London, and many elsewhere, are free to enter.

The costs that dominate are hotels in London and Edinburgh in season, walk-up rail fares, and attraction tickets at the major heritage sites.

What reduces them: booking rail weeks ahead, travelling outside July and August, eating the pub lunch rather than dinner, and using the free national museums. Membership schemes for heritage properties can pay off on a trip built around castles and country houses, but only if you will visit several.

Tipping is modest: around ten per cent in restaurants if service is not already added, and not expected in pubs where you order at the bar.

Queueing is taken seriously and jumping one is genuinely offensive. Politeness formulas (please, thank you, sorry) are used constantly and sorry often means excuse me rather than an apology.

In pubs you order and pay at the bar rather than waiting to be served at a table, and buying in rounds is the convention in a group. Tipping at the bar is not expected.

Understatement is the default register. Enthusiasm is expressed quietly, complaints are made obliquely, and directness that would be normal elsewhere can read as rudeness.

National identities matter. Scotland, Wales and Northern Ireland are not England, and describing the whole country as England is the most common way visitors cause irritation. Welsh and Scottish Gaelic are living languages with official status in their nations.

British cooking has changed substantially and the clichés are out of date. The traditional core is still worth seeking out done properly: the Sunday roast, fish and chips from a good chip shop, a full cooked breakfast, pies, and regional cheeses.

Regional specifics reward attention: Cornish pasties and seafood in the southwest, Scottish smoked salmon, venison and shellfish, Welsh lamb and cheese, Northern Irish soda farls and the Ulster fry, Yorkshire puddings and Bakewell tarts in the north.

The everyday food culture is heavily South Asian in origin: the curry house is a British institution, and Bradford, Birmingham and the East End of London have the strongest traditions. Tea remains the national drink, and afternoon tea exists both as a formal booked occasion and as an ordinary café item.

The UK is a safe country with low levels of violent crime. Pickpocketing and phone snatching from mopeds occur in central London and other city centres. Keep phones out of sight near the kerb.

The genuine risks are outdoors. British hills are low but the weather on them is severe and changes fast; Scottish and Welsh mountain rescue is called out year-round to walkers in inadequate gear. Check the mountain forecast, carry layers and a map, and note that phone signal is absent in many valleys.

The coast has strong tides (several beaches have cut-off risks on a rising tide) and cold water year-round. Follow the flag system on lifeguarded beaches.

Emergency services are on 999 or 112. Healthcare for visitors is not automatically free; carry travel insurance, and note the reciprocal arrangements that may apply to your nationality.
