How To Cut a Hole For Extractor Fan

[Skavenger]

I am replacing a kitchen and with it fitting a new cooker and hood, the old cooker was a 4 ring gas with a non functional hood but the new one is a ceramic all electric induction with hood. What is the best method of cutting a hole for the extractor unit? It is an outside wall to another property and will come out behind or just above a shed.
There will also be another extractor above the window / sink on an adjacent wall.

Some would hire a 100mm core bit and drill it out in one go.

We stitch drill a series of holes drawn around a piece of 110mm drain pipe, then remove the weakened masonry. It helps to drill a hole straight through the wall (both leaves) right in the centre of the intended vent, first.

You will need their permission to expel it onto their land if it is not within your boundary. Get it in writing - signed and dated.
