Hi,

Quick question.

Is it possible that a GCH installation installed by a non Corgi
engineer can be inspected, certified and given the neccessary
paperwork by a Corgi engineer at a later date.

Many thanks in advance.

Yes, only on commissioning. If the person who fitted the system was
"competent" and did not receive any payment, he need not be CORGI, fitting
for himself or anyone else.
