The Google maps images for the London area are out of date and lo-res. Someone commented recently that Google finally added hi-res images. But it seems that while Google Earth images of London are hi-res, Google map images are not. They seem to be out of date as well. And the hi-res images stop at the London city limits.
So Google, if you are listening, we would like recent hi-res images on both earth and maps for London and surrounding area.
