GMB British Gas - Updating your Details

GMB, the union for British Gas, are currently undertaking a ballot as your employer are seeking to change your terms and conditions, by looking to dismiss and re-engage you on inferior terms.

In order that we can ensure that you receive the correct information as quickly and efficiently as possible, we are asking all our members in Southern Region to confirm your details — personal details, employment details and, most importantly, how we are allowed to contact you.

We store all your information securely on our membership system, but we need to make sure this is correct.  You can read more about how we look after your data at

If you have any questions regarding any of this, talk to your local representative in the first instance, or call your Branch Secretary.  If you are not sure who this is, you can call GMB Southern Regional Office on 020 8397 8881 to find out.
