Dave - I have followed your idea - with an upward pointing tee with
about an inch of pipe - then down into my airing cupboard where a bucket
is awaiting any condensate that can't get out the blocked route.

Just makes sure no flue gases can get out of that pipe. With the fans
and things inside the boiler and the flue gases being forced out of
the flue the inside of the boiler will be at a higher pressure than
the room (airing cupboard).

Saw one of your other posts about access to the top of the soil
stack. Is that an internal stack? Connecting into that would be
better than the bucket and alarm, though not totaly sure about the
regs.

We had a warning pipe connected into the top of an internal stack.
Still worked as a warning as the junction into the stack leaked...
Fortunately it didn't damage any ceilings or floors.

First time I had used solvent weld joints. I now feel more confident to
re-plumb the waste in my cloakroom - ditch the white painted brown pipe
and get some white with the more compact solvent weld joints.

Remember that solvent weld does not come apart for the removal of
blockages or retreival of items. Planning access to each run of pipe
can save a lot of agro later.
