checked this recently. M&S t&c’s changed recently so much less good for bikes over (iirc) £1k, possibly £2k – they may not even cover them. Co-op would have been fine (with house insurance) but since I couldn’t say when my house was built, no go.
NFU came up best – great house insurance policy, plus bikes covered, all for 60% less than previous household policy…..
not tried protectyourbubble but some claim they are a pain to claim off – think there was a recent thread on here about it too…. but they may be fine, we all have some bad experiences…..
<edit – ouch – protectyourbubble comes to almost half what I currently pay for house, contents and bike, for bike alone……>
