If you realy want to spend some money for paperwork then you could either
ask the vendor to provide building regulations indemnity insurance (this
is cheap since it is to all intents and purposes impossible to claim on),
or you could apply to have the windows regularirsed by bulding control
(for which they will charge a fee).


Does Buildings Regulations Indemity insurance, cover the entire property
against BR enforcement or just one issue? I.e if the vendor is required to
takeout a policy for a conservatory, would this also cover then issue of the
windows? - does the premium change?
