I've mixed feelings about whether this is a good or bad thing. Four of the five nearest pubs to work are TW, after that its a toss up between GK and Fullers, then yet more TW outlets. It's legacy of Grotney's dominance of that part of London. All of the TW pubs suffer from poor beer quality, though they do ring the changes on the guests a bit for those who don't want Doombar or Pride. GK may well up the cellarmanship standards, but unless they adopt a liberal guest beer policy the chances of finding something you actually want to drink will be restricted.
