During Garys original round-up of his friends, you dont know the name of the companys theyre working for. Peter appears to work for his Dad in a car dealership, Steven builds houses and Oliver is an estate agent. The only company you actually catch the name of is Andys corporate lawyer firm Beckingham Davies Knightley LLB. Beckingham is a reference to Simon Peggs actual surname. He got rid of his original moniker on account of it sounding too posh it sounds incredibly similar to the Queens residence, Buckingham Palace and would therefore ruining his appeal as an everyman character.
