Rules & regulations
- This is structural work: engineer's calculations and building regulations approval are mandatory
- Shared chimneys on party walls need Party Wall Act agreement with the neighbour
- Leaving the upper stack unsupported is the classic cowboy shortcut, building control will check
Snap tips
- The engineer's design is a few hundred pounds; a dropped stack is a rebuilt house
- If the neighbour shares the stack, talk to them before the surveyor letters do
