Our estate was similar, but welded 2 to 3 years ago.
I have been using the mig spot weld method for years now and works well with a 7mm hole, 6 being too small and 8 being a bit too large, material thickness dependant. I slightly countersink the holes so no jagged edges of the holes and a good fit for the repair piece.
I have been using mig spot welded "inner plate" but you must remove the swarf and ever so slightly countersink the holes on the "inner side". This means that the hole seen in the green video, has inner plates protruding into the hole area, with a plate made to fit the hole. The plate can then be drilled to mig spot weld to the inner plate, as well as welded on the edges. More work yes, but a better repair imho, and stronger. Repair piece fits flush to original level.
No issues MOT wise, so far.
