With the first, the Council checks that the windows meet the
requirements, for a fee, and issues you with a certificate if all is
OK.

Can the certificate be granted *after* the windows have been fitted?

I'm tempted to fit my own but I don't want to pay an extra seventy
quid. Would rather risk it and get the cert if I get caught out.

Failing that, is there a date stamped on the windows anywhere?
