Apologies for reviving yet another insurance thread, but I’ve found the same as above – when I added the bikes on M&S the premium shot up, but I upped the excess and it brought it back down to almost the same price as before (£200 seems the sweet spot – increasing to £250 not really worth it). M&S certainly aren’t the cheapest for basic insurance now, but they still appear pretty good value when adding several expensive bikes compared to the alternatives – have tried lots of companies today, and when adding my fleet they were all lots more expensive if they’d insure me at all. M&S terms also still seem a bit better.
I guess most people on here don’t actually have a fleet quite as expensive as mine in total though, even if my most expensive isn’t actually as expensive as others have. I got a much better deal out of old M&S terms than most because of number of bikes – and no, it’s not my faulty they’ve changed it, as I’ve never claimed on my M&S policy.
