Coco,
Apologises. When I said check the screws I meant at the termination block between the old wire and the new hood wire. This was in case the wires inside the termination black were not properly connecting to metal (all it needs is one wire ):
Hey, yes I checked as I’ve had this problem before. The screws were all sitting firmly on the copper wire end and I made sure to tug gently to see that they didn’t fall out
NO! You need a multimeter to check the white cable on blue and brown wires. Supposed to be 230 volts AC although 240 and higher is more common. (mine was 258VAC last I checked). Test using the block you connected up to the extractor as it's safer for you.
If you can not test for yourself, you need to get someone in to test for you. It does not need to be an electrician, just someone with a meter and a clue how to use it !!
Coco,
Sorry to say that I think I have reached my ability to advise from a distance as all my following suggestions need a suitable CAT III multimeter and experience handling one around live cables.
I feel it is time for an electrician or someone with more experiance to determine the source of that cable and why no longer live.

The white supply cable coming out the wall has several indentations/ damage to the outer sheath ,as though it has been bent sharply and clamped. Maybe one of the inner conductors is broken.
Do you have a fuse board or a consumer unit with circuit breakers ?
What exactly did you do to isolate the extractor originally ,before removing it ?
When mounting the new extractor ,did you have to drill into the wall ?
Are any other sockets or appliances not working ?
So I decided to leave off tampering with wires as it just seemed too fiddly (and dangerous). I drilled a hole in the unit instead to pass the power cord through. I reattached the plug i’d initially cut off and also extended the length of the cable so it would reach the nearest socket. Problem solved!
Thank you all so much for your help and sound advice throughout this ordeal. I’ve definitely learned a few new things along the way
