It was quite a whirlwind ride for me to get settled finally in the UK after being offered to do so around in late November 2021. My employer, Apple, helped me a lot and frankly it has been so smooth for me so far since the 4 months that I landed here. The VISA process took around 1 month and after coming here I was able to get a rented apartment, bought a car on finance, got a credit card, setup my apartment and got my booster COVID-19 shot!
Some of the absolute essentials that folks who have moved to the UK with a job must have and are different from how it works in India -
1. Renting an apartment. The process of renting here is very transparent and the deposit is held with a Deposit Protection Service, so it's never a unilateral decision of not paying back the deposit held. I'm looking at you Bangalore land-lords!
2. SIM card - Of course, one of the first things you need to survive in the UK is phone number. You can get one from the airport, unlike in India, you don't need to provide your Adhaar or Voter ID card for this (or any form of ID, you can get it in a vending machine)! Any provider is fine, do check if they have 5G.
