Best Time to Visit

London is graced with a mild climate and, as such, can be visited at any time of the year. However, a few things need to be considered. Most of the royal palaces and residences, like the State Rooms at Buckingham Palace, are only open to the public during the summer months. Many of the city's most important festivals, like the British Summer Time Music Festival, also take place during this time. Late June to mid July is also when some of the best sales are on in shops around the capital. Spring is also a good season for a visit, since the weather is generally good and finding accommodation is both easier and cheaper (high season in London means a lot of tourists). And if you're not too bothered about the grey weather, then low season (January and February) can be a good option too, when there are fewer tourists and prices are lower.

Passport & Visa

For travel to the UK, citizens of the EU, EEA, and Switzerland (except Irish citizens) need an Electronic Travel Authorisation (ETA). However, those planning to work or study in the UK for more than six months will need to obtain the appropriate visa. Additionally, residents of nine other countries — including Australia, Canada, Hong Kong, Japan, Malaysia, New Zealand, Singapore, South Korea, and the United States — can also visit the UK for up to six months without a visa, but they will still need an ETA. To ensure a smooth journey, it is advisable to consult the UK government website for any specific visa requirements or regulations.
