Your kitchen tap comes straight from the mains supply, that is OK for
cooking and drinking and to the appropriate specifications.

You should not use any water from an attic tank for cooking or drinking,
because the problem of sludge in attic tanks which you observed is common
in UK houses.

Hot water from a combi is OK for cooking and drinking, because it has not
been stored. I have had this from an Environmental Health Officer.
