So the cage insurance comes up for renewal, and after a bit of clicking about I get one a bit cheaper than the renewal notice. This is quite a lot cheaper than last year, which is nice. But anyway, the "Renewal Advice Note" that the outgoing ins co sent out as proof of no claims has the following: Basic: +21 Age: +2 OOD: -8 AOC: -2 CONV: +5 SCH: -9 So what do the above mean?
