Our 1969 semi-detached house has never had a fireplace so the chimney is capped
(and the bottom is open to the under-floor space).
I am thinking if removing a brick from the chimney in the loft to provide some
additional loft ventilation. Can anyone see a problem with that?

Most homes on that tiny island nation were constructed (poorly) by drunken
englishmen. Removing a single brick from your shanty could cause the entire
neighborhood to collapse.

Not that I can think of, I can't imagine that it will provide a huge
amount of airflow so if you do need more ventilation in the roof space
(do you?) I'd have thought a more rigorous method would be called for.

I did this, not to ventilate the loft (for which this won't
make any significant difference), but to ventilate the flue.
If any of the other flues in the stack are in use, then you
need to have them leak tested to ensure they aren't leaking
into the flue you are opening up. Having done this, it was
also very useful to drop cables from the loft down in to the
dining room (in my case). I have wire mesh over the opening
to prevent any animals going through it in either direction.
I actually only took out half a brick, and carefully chose
one which wouldn't weaken the stack, which is corbelled all
through the loft.

Some years later, I had scafolding up the outside to the top
of the stack, and then put in a proper air brick near the
top of the flue, which should have been put in 25 years
earlier when the flue was blocked off. The vent in the loft
was a temporary measure until I had access to the outside,
although I've left it open too.

I did it today and decided that 1/2 brick (+ mortar gap) provided a reasonable
sized hole. Can feel a bit of a draught now.
May rig up an old PSU 240v fan to extract into it.

Thanks to all for replies.
