A few years ago the Pound was very expensive – SEK 15.50 at most. London and the UK have been gradually getting cheaper. Today (19th of March 2010) one GBP costs SEK 11.23.
Buy your Pounds before travelling. London’s bureaux de change aren’t to be messed around with – up to 10% of your Swedish Crowns can disappear through bad rates and fees.
Prepare yourself for crowds on pavements, busses and on the underground. Taxis are the best way to get around the city of high congestion charges.
