There are almost 200 hours difference annually within different locations of the same city! Why is this?

London - Wikipedia, the free encyclopedia
Greenwich is a rather dull 1480.5 hours
Heathrow is almost as sunny as Paris with 1632.6 hours

The view is obscured by tall buildings and their shadows, and can't pick everything up. I thing B87 said something like this. Makes sense.

There are no tall buildings near the Greenwich station. It's due to terrain blocking the shadows. Also, the climate box for Greenwich is for 1971-2000, not for 1981-10 as it says.

Here is the actual data.

The actual, or current, data for Greenwich is even duller! Between the period of 1981-10 heathrow has around 220 hours more sunshine than Greenwich...

Here's the location of the weather station. Looks like a combination of trees and the big hill to the west. I doubt it's anything to do with low cloud from the North Sea, as Gravesend pretty much on the estuary gets over 1600 hours as well.

Strange, why would you put a weather box under trees if it's not giving you an accurate description of how much sun the area is actually getting?
On a tangent, that Google photo of the area makes Greenwich look more like somewhere in the dry med, when was this taken... The grass is so brown!
