Hey I’m UK based too. Those amounts are way higher then what I’m on, 60k. I’m curious about the type of companies paying such TC, do you have an email to chat more?
You can get above £100k fairly easily by working in finance or even just a profitable PLC in London (eg I know of Sainsburys offering that several years ago albeit for an EM role). Even if you don’t like investment banking or hedge funds, high street banks also pay well and have generous pension, annual leave etc.
