IMO that wall should be removed and re-laid - as well as being cracked - it's displaced outwards a few mm. Does the veneer wall move if you push it?
The vertical crack in the perimeter foundation also needs to be fixed - epoxy injection. It looks like 1-2mm wide, not considered "structural" so exempt from consent, but a point for moisture ingress and corrosion of rebar.
If you did gardening to expose this damage, EQC have the excuse that they're not allowed to do anything destructive when carrying out inspections. I had issues with this, they wouldn't even push back branches of shrubs to look behind. Similar with damage to floors etc, they won't lift floor coverings - that's up to the homeowner.
No, the gardening didn't expose it, I was just trimming a couple of bushes on either end of the wall, the crack itself goes 2/3rds of the wall.
The reason why it was missed was because you have to get down on the ground to see it because the bricks are displaced outwards, (I was bending down picking up branches and saw it).
If they were to replace the brick / SHS, then they're unlikely to be able to get a match to the rest of the house. Someone has to make a decision in the case of minor cracking whether to fully reclad or repoint only the affected area. Repointing some minor cracks is probably ok if the walls are otherwise sound - but I'd have thought that if there was other damage - then they'd have at least bothered to look for damage as you show in that photo. Very poor of EQC not to have picked that damage up in their inspection(s).
Around where I am (hills) , failed SHS has generally been replaced (full house re-clad) with 70mm clay brick. Doing that's consent exempt under present CCC guidelines, and not particularly expensive work.
If the brick veneer wall moves when you push it (insufficient, loose, or damaged tie-backs) then it could collapse in another shake.
If that foundation is as low as you suggest - is it a perimeter foundation with wooden floors - or slab on grade? If slab on grade with a crack extending to the edge of the slab, then the slab needs to be checked under the floor coverings. Some minor (shrinkage) cracking is normal, but if the cracks extend to the edge of the slab there could be bigger problems.
