Last year I had to pull out of a ski touring trip after stubbing (and I suspect breaking) my little toe. The NHS advice for this is that it should get better in 4-6 weeks without any particular treatment, which indeed it did. In the end the provider was able to re-sell my place and most the travel was refundable/transferable so it wasn't worth making an insurance claim but it wouldn't have been particularly straightforward if I had needed to.
The BMC insurance (although this seems pretty standard) cover cancellation due to illness but require a medical certificate when claiming. GPs will generally fill out the form for a small fee. This is fine if there's something seriously wrong that you're receiving treatment for but there are plenty of conditions which don't require a visit to the GP but would still preclude going skiing (apart from my toe, flu/covid spring to mind). Does anyone have any experience of claiming in this sort of situation?
The only advice my GP surgery had was to call 111 and describe the symptoms so at least there's something on the medical record they could make a statement based on; I'm wondering whether "patient reports they have a runny nose and headache" would really cut it though. I also notice Snowcard only cover Covid cancellation with a positive PCR test. I'm not really sure how you'd go about getting one now, and it's a bit of a problem if the test comes back negative but you're still laid up in bed.
I'd be interested to know if anyone else had looked into / dealt with this and if any insurers are better than others to deal with.
