UK postcode handling a bit off

The way your geocoder is handling UK postcodes doesn't seem to be quite right - for example, my postcode, E11 1BG, produces a result of "Ilford", which is another area entirely; Ilford postcodes begin with IG1. Plus, on the map view, it's some distance off from the actual location. Compare:

http://maps.google.co.uk/maps?q=E11+1BG - where I am

http://maps.google.co.uk/maps?q=E11+2JR - more or less where your map view shows.

Thanks.
