We filled these cracks so that we may study future movement. Two
years on, the wall seems to have shifted by another mm or so.

The wall isn't sinking - there are no cracks at floor level
downstairs. The cracks appear about 1m above floor level, and
increase in size as you go upwards.

What are you waiting for - are you skint? a cheapskate? stupid? naeive?

Get a structural engineer in fast. It will cost around £175 to £400 or
so, for a visual inspection, initial prognosis and advice for further
inspection and/or cure.

The longer you leave it, the more chance of having to rebuild the wall
than using simple metal strapping.

I would get the engineer 1st - before involving your insurance co.. You
may not need, or want, to bother with insurance.

This is not Do It Yourself - you need the correct paperwork to satisfy a
surveyor when you sell.
