The amount of money you will need as a tourist in London depends on several factors such as your travel style, accommodation preference, food choices, and activities you plan to do. However, to give you a rough idea, here is a breakdown of the average daily expenses you can expect: Accommodation: £60-£200 per night depending on the type of accommodation and location Food: £15-£50 per day depending on the type of food and where you eat Transportation: £6-£10 per day if you use public transport Attractions: £20-£40 per day if you visit some popular tourist attractions Miscellaneous: £10-£20 per day for things like souvenirs and incidentals So, for example, if you stay in mid-range accommodation, eat moderately, use public transport, visit a few attractions, and budget for some miscellaneous expenses, you can expect to spend around £80-£120 per day. Therefore, for a 7-day trip, you can budget around £560-£840 excluding the cost of flights to and from London.
