We are buying a house with a garage extension but apparently no
building regulations consent for the extension.
Any advice will be appreciated.

This crops up fairly regularly on uk.legal and I think the usual answer
is that after its been up 4 (?) years they can`t force you to knock it

Yes - after 4 yrs it's untouchable. No guarantee it's been built properly,
of course.
