All UK and EU consumer insurance products, which includes travel insurance, by law must include an Insurance Product Information Document (IPID), which should contain, in simplistic terms, all the major risks covered and all the major exclusions.
If you don't find what you're looking for on this, there is the insurance policy. If it's stated as covered on the policy, it's included. If it's not covered on the policy, or appears in the exclusions, it is not included.
Consumer policies are now written in relatively simple language in order to make them understandable by members of the public with no knowledge of specialist insurance terminology or legalese.
I'd like to know what you mean by stating that coverage info is not forthcoming. It's right there in front of you, written in the policy.
