I’ve often endured the Kwik-Fit depot with often being turned away to have to go back hours later, even with appointments, so now use the mobile service that I’d give 5 stars for over the depot’s who I’d give 2 stars.
I’m not sure if you can book the mobile service without a Motability online account to contact Kwik-Fit but if you haven’t got one it only takes a minute to set up.
