Cutting 300mm hole in lath and plaster ceiling?

[john999uk]

I have to fit a condensation control fan (PIV) into the hall ceiling. The hole needs to be about 300mm and the ceiling is lath and plaster!

Any tips for cutting the ceiling without damaging the surrounding lath and plaster?
Cheers

All done . The multitool was great. Actually once I started it was easy as the ceiling had been overboarded so the laths and their plaster were all contained. So no need to worry.
Cheers for all the advice it was very helpful.

Lots of DIY at moment, had to sort out very bad condensation at bungalow, hence this thread.
Hope you are keeping well. Are you still working or finally taking it easy and relaxing?
