Already Chartered?

CGeol Logo       CSci logo

The award of Chartered Geologist or Chartered Scientist acknowledges that you have reached an important professional milestone. Chartered status is a symbol of technical competence and signifies a public commitment to professional standards.

As a Chartered Geologist or Chartered Scientist you can:

  • use the post-nominal letters CGeol or CSci;
  • use the CGeol or CSci logo in your e-signature - CGeol ink-stamps can also be ordered; and
  • be listed in the online register of Chartered Fellows.

In order to retain your status as a Chartered Geologist or Chartered Scientist you must:

  • remain a paid-up Fellow of the Geological Society;
  • abide by the Society's Code of Conduct; and
  • continue to maintain your CPD records – each year, you will be asked to affirm this action and a percentage of Chartered Fellows will have their personal development record audited.

Please keep the Society updated with changes to your contact details as we may be obliged to withdraw your Chartered status if we are unable to contact you, e.g. to notify of outstanding subscription fees.
