Not as easy it could be. If going via Flight Connections, the last stage before getting fully airside is security, often called North Security by the inmates here. After completing security turn right, towards a big Harrods sign. Walk past the shops and you'll come to another security area (South Security), keep walking and you'll see a fairly discreet door right at the end, and a staff member by a pulpit outside. It is signposted at this point, but you won't see that from a distance. This is the best entrance for you and doesn't involve any stairs, it's all on the same level.
