Some of the ones that made me move out of London:

- pollution;

- poor quality in most housing;

- small apartments (shoeboxes really);

- high rents and difficult to buy;

- crowded (streets, public transportation, roads);

- both of which leads to people being pushed to the outskirts and taking a lot of time to travel when you want to meet with friends;

Personally I got a bit tired of it, loved it in the first few years. Lots of money to be earned, and quite a lot of facilities, but for me I just grew tired of the place.

Travel time to meet with friends was a big one for me. My job was never in the centre, so I chose to live within 15 minutes cycling of work, in a pleasant and green bit of West London (Z3/4). That was fine when the fun things to do were in the centre, but a lot of them moved further away. That led to an hour's journey to see a metal band perform in Holloway, and then a 1½-2 hour journey home at night by bus, or £60+ for an Uber.

London has half as many licensed music venues as in 2004. ([1] says 35% less since 2007, I can't find where I read half.)

Also, I said I'd leave the UK if UKIP got more than 20% (or 25%, or something) in the 2014 European elections, and stood by my word :)
