The other change I think is quite likely is the removal of the
exception from smoke control areas for wood-burning stoves in
places like London, possibly as soon as October. That will mean
no more buring of wood in them, and will be retrospective. This
is easily enacted just by reducing or emptying the list of stove
models which are exempt from smokeless fuel regs and doesn't need
any legislative changes.

Changes to building regulations do not usually affect existing
installations. Why do think this one will, and for that matter what is
your source for this information?
