I had an older version of this http://www.mega-vehicles.co.uk/en-e-worker-van.html
Too slow and short a range for travelling but great for tootling around central London and looks like they've upgraded the battery options since then.I can't find it now but UPS were using big electric vans for a while. Looks like things have come on a long way with options from big manufacturers as well now.
Depending on your usage, there are loads! I was driving an electric noddy-van for work 4-5 years ago!
