Your relocation to London is not all about paperwork, leases and council tax. You need to make sure that you are able to spend some time exploring and discovering everything that London has to offer. It is hard for people after a relocation to London to spend weeks trawling the city like a tourist. You are building a life in the city and that usually means a full working week and domestic chores on top of that.
Making sure that your weekends are clear is an important part of the settling-in process after your international relocation. London is a city that is rich in arts and culture and spending some time immersed in the arts world will be a rewarding part of moving to London.
