That seems absurdly low. My 250w panels get within 90% of rated output and I'm in Seattle.

I think they're averaging throughout the year, using the number of "Mean Annual Sunshine Hours" * "Percent Possible Sunshine", which would account for average cloud cover and such.
I'm sure that for a few hours during the summer, the solar irradiance in London is probably 90% of what it is at the equator. That doesn't help most of the year.
