Every employee is given a one-time opt-out window when they’re first enrolled into a workplace pension scheme.
In your case, that window would have started when your employer initially enrolled you into the previous pension scheme. Even though your employer has now switched to Jarvis, that original opt-out window doesn’t reset with the change in provider.
But not to worry, you can ask your employer to stop your contributions.
To do this, you'll need to do the following:
Open the enrolment email you received from Jarvis*
Click on the purple button in the email that says 'Get started with Jarvis' - this will open up the website or the app if you already have it installed.
Click on 'Existing user login'
Click on 'Email Magic Link' and use the email address you received the enrolment email to/the email address your employer has for you
You will be given an option to connect with your employer - connect with your employer.
Once you are connected, tap the menu icon in the top left corner.
Click on 'Workplace Jar'
Click on the name of your employer underneath 'Contributing Employers'
Select 'Request To Leave Scheme'
This will send a notification to your employer who will action this for you.
*You will need to make sure you have connected to your employer to get the option to opt out.
