LONDON: Need a little help

So I've seen a few posts like this on here over the years (I'm an avid reader, though not much of a reader) and thought it is maybe my time for a go.

My name is Gary, I'm a 23 year old Software Engineer who moved to London from Scotland 3 months ago, I work at a really small development company which I love, but it is mainly remote workers or older guys with family's. Having never been to London before, I don't have many roots here and have two friends from back home who moved here not long before me, but they have picked up new friends from work/flatmates and have started to develop their own friend groups, like they should.

Unfortunately I've not been graced with these circumstance. I'm aware these things can get pretty bad, and I'm determined to not let it go that way. I'm not used to feeling lonely as I had a great friend group back home but I feel that it's starting to get me down. I've contemplated leaving and going back home, but that is something that I really don't want to do. I do love London.

So really what I'm asking - is there anyone around Central London who would want to meet up for a coffee or a pint? I'm just a generally chatty Scottish guy who is looking to meet some new people.
