Core drilled through end of Lintel & metal showing

50mm will not work. sizes I have seen are 150mm 125mm and 100mm in rounds and there are reducers for each. Then there is flat 50x100 and 50 x something wider than 100mm.
Have a look here there are all kinds of options and adapters flat to round etc https://www.i-sells.co.uk/plastic-ducting-selector

Wow what a difference how neat your venting is up to how the builder left mine !

It was not pretty until i put the plaster undercoat on to tidy it up. When the plastering and painting is done i will fix it in properly. I left a small gap around the pipe so i could get silicone around it and that silicone can be easily cut in the future so i can remove for maintenance if needed. The pipe will be on top of tall wall units and boxed in a bit like yours. Pencil mark is the top line of units.

I hope I've got this completely wrong.... I've been re-reading all your replies and noticed area on my pic's ...

Is there bricks missing on the internal wall under lintel ?

( I'm sure it is where they knocked out the original concrete window seal covered with white plastic)

I attached pic original internally & externally of kitchen window & door

cant see why they would need to chop out that area so i think it is likly to like that from new build - see what others think

It's just a bit of the cavity closer, nothing to worry about. A real builder would have removed it all to continue the insulation but hey ho.

No point changing the ducting now, the damage has been done.

That's a relief ! Thanks for your help

You are starting to "over think" it. You are not the first, and certainly won't be the last , to have building work done that does not meet your expectations. Maybe a second opinion from another builder to visit on site ,recommended by family/ friends, to put your mind ar ease.

Definitely needs a pair of expert eyes.

Speak to the council first. I'd hope they'd be interested in the lintel at least, perhaps a conversation will result that guides you in a helpful direction. Although councils will not normally formally recommend anyone, you may get guidance.

Councils have/sometimes have, a list of proper trusted traders. Worth asking.

Possibly true for council employees, but the council itself often have lists....

See the link below.

Find a trader and check you can trust them

Apologies I've not replied sooner... Having difficulty charging my phone (will buy a new mobile today)

I will get advice from another builder... and I will ask about for recommendations.

Please can you give me advice what to look for to ensure the builder knows how to sort out the problem with the brickwork. Obviously I will make sure the builder can spot the problem and explain how to solve it but is there any questions I should ask ? (don't want the wool pulled over my eye's again !)
Thankk you

Ring your local town hall, and ask if they have a list of known to be competent builders.

When they're done it should look like the rest of the wall, staggered bricks of a good blended colour match, not like a stack of wrong-colour/size bricks one on top of the other
