Our electrician has fitted a bathroom extractor fan above the bathroom window. The hole for the fan starts a few cm above the window, which means that the bottom part of the hole (about half of it) has been drilled through the concrete lintel. The electrician says this is ok and there's no risk of structural damage as the hole is made towards the edge of the window. Is this correct?

No it's not correct. Can you post a piccie? Only a nutter would attempt to drill a hole directly above an opening.

What are the structural engineering qualifications of this electrician to make such a bold statement? If more qualified than my spaniel, then it may be OK.

Can we find out where he buys his core drills from or does he use semtex?

That's more than a "few cm" and probably clears the lintel?

That depends on how thick the lintel is and how much plaster material there is filling out the header. It could be a 140mm deep fella if there is a roof bearing wall plate above.

Fair comment. I should think a lintel would be a nightmare to core drill? Only way really is to clean the hole and take a pic of the material at the bottom?

Is the bathroom external wall on a gable elevation or is there a soffit overhang? Looks like that would exit into the eaves if the latter....:unsure:
Oh, I don’t think I know what all these words mean but I think the fan exits through the wooden overhang

Material at the bottom and half way up is Concrete, material at the top of the hole is brick

Does sound like a bit of the lintel has been removed if you can see concrete! What is above and how wide is the window?
