But can you still get house insurance ?

What's the figure (worryingly large) for the estimated percentage of
gas installations that are non-compliant? AFAIR, the figure for
installations that are 30+ years old (and that's a lot of
installations in older houses) is the majority of them, mostly for
inadequate ventilation.

The problems with gas aren't just bad new installations, the old ones
are a risk too - especially if new work for draughtproofing etc.
reduces what little ventilation there was to begin with.
