Not had much look with Vertu KIA. They only stock Slime brand kit, rather than the OEM Continental kit that is easy to use and worked well.
Not only is the Slime kit fiddly (dismantle valve and then reassemble valve), the kits they stock can’t even be used on SUVs (only cars up to a limited wheel size).
Motability were useless. I had to either buy the correct kit out of pocket (couldn’t claim cost back), or follow their advice – call RAC.
I know a lot of people have had extremely long waits for RAC. Ideally I’d have a spare wheel, but being a MHEV, the extra battery is in the spare wheel area.
