Gibbo it may benefit others, (and nosey prople like me), who may go through the leased battery route on a second hand Zoe.
On transfer of the lease do RCI require a "State of Health" Battery report at the point of transfer, or indeed seek any evidence of confirmation of service history I wonder if the small print on transfer gets you to confirm that the vehicle as you receive it, has been maintained in accordance with manufacturers recommendations, even though you would have no evidence to support that it has unless it had a fully stamped service book.
The Zoe you are purchasing presumably has under 30,000 on it....based on the last MOT on the DVLA, so I would think that the battery still has a good SOH, and from what I have read degradation of the Zoe battery isnt a great problem, and the 75% trigger hasnt been reached for the older Zoe's on the road and our friends at RCI havent been inundated with claims.
A report I read on "Speak EV" from July 2020 indicated that pretty much the base battery buy back price was £2,750 for the 22kWh Zoe for one of the older Zoes (2013 given as an example) from owners getting quotes from RCI.
