£12k.

A used ~2012 Nissan Leaf or Mitsubishi i-MIEV (Citreon C-Zero, Peugeot Ion)
start at about £5K.

Obviously whether they're suitable for you will depend on your use case.
(in particular the range of 60-100 miles means they're not ideal for long
journeys)

There's also the Renault Zoe in that price bracket, although the battery
leasing makes them less attractive unless you do a lot of miles.
