Also there are a lot of fintechs (or pure finance) that will pay more than that. I'd say after about £160k you're going to struggle without moving into some kind of management type of position, though, if you're not at a FAANG or extremely well funded startup.
Also bay area COL is substantially higher than London. I live in a 4 bed house a 30 min cycle from the City (where I work), and pay around £1500/month.
