Some of the larger banks can now provide your statements in English, if you request it.
If you're here on a temporary basis with yours or your partner's work, then many of the banks here will offer Expat services and even special Expat accounts. However, the branches in Bruges may not be aware of this, as most of Belgium's expats are based in Brussels! If you're met with blank looks in Bruges, ask them to check with the Brussels office or just go direct yourself.
