Open a bank account with a well known "physical" bank (ex: HSBC, Barclays, etc.) as well as a digital bank (Ex: Monzo, Revolut, etc.). The idea is to have your income deposited in the physical bank along with rent and utilities payments whereas the digital bank is to be used for your day-to-day payments. This setup has a couple of benefits:
Get into the habit of investing a portion of your monthly income, be it in stocks or other instruments. These small monthly investments will compound over the long run.
It is easy to get caught up in the day-to-day routine and to forget to recharge. In my case, this led several times to mild depressive episodes. Remember that the UK offers easy access (hop on a train and you are good to go) to the countryside and seaside.
For the most part in the UK, I got used to run alone, which helps in clearing my mind and to listen to my own thoughts patterns. However, very recently, I came to realize that the UK is full of sport clubs (running, cycling, etc.) and it helps, from time to time, to practice in a group. It is also a great way to connect with others who share similar sport habits/passions.
