"Outside uninsulated needs to be 40mm by regs. It's an easy job, but you'll need a 42mm core drill."

"It depends, what size the pipe is. If it’s underside, it could be upgraded but ideally needs running inside if possible"

"Hi. It is always best to bring in a skilled tradesperson for situations like this, as it may not simply be a repair, but the installation itself may need to be adjusted/corrected in order to avoid future problems."

"Depending on how badly frozen the pipe is, if it is that it has frozen externally near to the drain or soak away use warm water to warm the condensation pipe remove the ice etc. If not call a local plumber, shouldn't cost an arm and a leg if it's merely a frozen condense 👍
Hope this helps.
