You will need to pay for any amendments after renewal separately by card. These amendments will be saved in MyGSL and will be incorporated into your Direct Debit payment for next year's renewal.

General enquiries
Membership renewal invitations are sent two months prior to your membership expiry date, with details of existing subscriptions and membership option (e.g. Chartership) and how to pay.
When this period ends, we offer a generous 'grace period', during which members can still renew their membership and regain access to their membership benefits.
The grace period for renewing membership will end six months after the expiry date. This final deadline is set in accordance with the Society's Regulations.
If your membership expired less than 12 months ago, please contact our membership team to discuss your options by emailing membership@geolsoc.org.uk or calling +44 (0)207 434 9944 (Mon–Fri 9.30am-5pm).
If your membership expired over 12 months ago, you will need to re-apply using our online form and be re-elected.

The Geological Society's owned and co-owned journals moved to electronic-only publication from January 2021. This means that the Journal of the Geological Society, Quarterly Journal of Engineering Geology and Hydrogeology, Petroleum Geoscience, Geochemistry: Exploration, Environment, Analysis and Geo-Energy are now only available online.
The removal of print will be accompanied by a move to a continuous publication model that will allow the authoritative version of articles to be published more quickly. Alongside modernisation of the Society's publications and improvements to author service, there are compelling environmental reasons to cease printing journals and so help to reduce the Society's carbon footprint.
Print copies will continue to be produced for other journal titles and books, including Geological Society of London Special Publications.
Information on how to access your chosen online journal(s) can be found on our Fellows' access page.
Email the Society at renewals@geolsoc.org.uk. If your payment method is Direct Debit, you should do this immediately so we can stop your instalment(s) from being collected.

Contact Membership TeamWe are working towards aligning your first Direct Debit renewal payment to the start of your membership, which needs to be done in two stages. Last year, we moved the first collection from 10 November to 5 December. This year, we are moving to 1 January, which will align to the start of your membership.
