• I have worked abroad using my BGAS/CSWIP approval for the past five years and I am unlikely to work in the UK in the short term. Do I need to re-sit my examination or can I receive automatic renewal if I send an authenticated CV from my employer?
• I hold a valid BGAS/CSWIP Senior Pipeline Inspector approval that is due for renewal shortly, can I re-new without the need for re-examination or will I have to re-sit my approval?
• Where can I get copies of National Grid specifications?
