I have admiral multi car, RS insured for 4000m@yr personal / pleasure & 2014 fiesta 24,000m@yr business use.
Was cheaper for a couple of yrs, on this yrs renewal went up considerably (as all policys have), got individual policys qoutes for around £95 less, rang up admiral and surprise surprise they reqouted within a few pounds, kept the multicar for the sake of a couple of pounds and hassle of providing proof of this and that.
Every yr at renewal time I always go out to the market for best prices – individual policy/ multicar.
It’s an individual thing, just cos one insurance company is the best deal for one, dosnt mean it’s the best for another, need to go onto the comparison sites / insurance sites and tap in u details to find best for you.
