Yes.
Tell us some more Richard. 1500 Kg per vehicle per day or more than one vehicle? Over what sort of distance per journey and how many journeys? Would you be able to include a pedal assisting rider to remain within the UK law, or are you prepared to add road vehicle testing, licensing, insurance costs into your equation?
There are perfectly formed electric vehicles operating in the UK in various guises - in parks and on golf courses for instance. But for legal use on the highways then a converted trike may be your most economical solution, so long as your possibly high profile (why not) project stays within the 15 mph, pedal assist limitations.
Take a look at some of the more powerful kits listed on these forums. Other suggestions will be along shortly...
Good luck to you!
