Just to piggy-back, these maps often don't show urban density very well. I'm guessing that Kettering (which is reporting "Leave") has a few less people than say, London.
Similarly, here is the 2012 election county map where "blue" had 5MM more votes than "red": http://politicalmaps.org/wp-content/uploads/2012/11/2012-usa...

That's a good point.
The Guardian do good election maps – this one has regional results scaled by population, so it's much clearer what's happening: http://www.theguardian.com/politics/ng-interactive/2016/jun/...
In the case of a general election, we have the previous election on which to base our expectations. The UK broadcasters use the "swingometer" (https://en.wikipedia.org/wiki/Swingometer) in these elections, which is a useful visualisation of the change of vote share on a per-consitutency basis, indicating the meaning of the result rather than just the number.
The EU referendum has no recent comparable campaign with which it can be compared, making it much harder to do this.
