3 checks to if in London
London underground station is one
Met police covering the area is two
Within m25 is 3, London orbital and all that
Watford has ,2/3
and again what?
the only check is whether it is actually in London or not. Is it part of a London borough? No its not, its part of a county outside London called Hertfordshire!
Re your 3 point check:
1) Plenty of underground stations outside London
2) Covered by Hertfordshire constabulary
3) A road doesnt determine where a place is lol
