Thanks all.. I'd spoken to recticel this morning over the phone and email. They've also confirmed in writing that it doesn't look correct. I went armed with this information and the instructions of how to Install this insulation. The building firm we've used, subcontracted the bricklaying out, and our building firm, didn't QC/Oversee it, it took me to notice it. They have agreed to rectify it from tomorrow. I think they are potentially going to take the blocks (inner skin) down and relay them, with the insulation attached properly. Do you think this possible? I've got to meet them again on site tomorrow to go over it what they will be doing.

Thanks. Is that something that can be done without removing the inner or outer skin?

There is a gap here, as they just have cut the tongue off.

Thanks. They are about 2/3 of the way up for the ground floor, still a bit more to go to finish ground floor, then they'll start on the upstairs. This one seems flush against internal wall, but the gap between external wall has snots. Again they've not used cavity clips to hold it tight against the wall, although there isn't any movement, I assume because of the snots.

Can we get a building inspector to check this? I am thinking, if they say its fine, I could suggest getting it checked if they are confident it's ok. If they say it's ok, we carry on, if not they rectify...?

Or they take the outer skin down and start again? Doubt they'll want to do that though..

Could installing insulated plasterboard help? I know it will eat into the room space...

This is video of one of the walls, the internal block wall is on the left... VID-20250311-WA0003.mp4

Thanks, I will try find it and have read. I've printed the instructions off for installation, I need to work out what the best solution is to rectify the existing, and ensure going forward they do this correctly. It's frustrating as they've bought all the materials apart from the clips (which aren't expensive), but just cut corners on the work, which wouldn't have taken much extra time in the grand scheme if things.

Extension to an existing house. We bought it about 2 years ago, but not lived in it yet, waiting until it's fully completed. The builders have done the extension to a close friends house about 5 years ago, and done all the internals, including plumbing, electrics etc and were happy with it. From what we've seen, we also thought ok. But now we are analysing everything and wanting to ensure everything is done properly.

Thank you. The builder said it should be fine... He's outsourced the bricklaying, but i dont think he's QC'ed it. I'm meeting him on site tomorrow, when the bricklayers are back.. I will print this off and ask him to look at it, I'm sure he will agree, that it's not fully to this spec.

There is a gap here due to the insulation from a cross section pushing against this piece.

I think I am going to have to have a chat with the builders. Just trying to arm myself with all the information so I know what I am talking about, otherwise they may just tell me everything is fine.

Thanks, as we are going double storey and they've only built upto just under single storey so far, is it easily rectified? Or does the wall need to come down? Does building control check it's been installed properly? Or is it difficult for them to check, once both walls are up?

They did the block wall 1st then attached the board and then outer wall. They used the metal ties to attach the insulation to.
