Neighbour's Kitchen Extractor Pumping Into This Flat

[rideforever]

Hello
The neighbours downstairs (Victorian conversion 2 flats) have a kitchen extractor going into a pipe in their ceiling that has no known outlet port and when they use it for cooking, it fills this flat (upstairs) with the cooking smells.
I suggested to him that he should fit a new pipe to take the exhaust outside.
He suggested I rip up my kitchen floor.
Could somebody advise me ?
Cheers

lift your floor and block the pipe.

Lift your floor and fit a fan going the other way into the pipe, from the sewer

It was more a question of which building regs apply ?

You don't need a building reg to tell you it's wrong, thatcommon sense!'s just

Neighbour is obviously not feeling cooperative, do you own the place or rent? If renting, get onto the landlord. If you own it, get on to Environmental Health at your local council.
