You need to ask the pension provider for an opt out form so you can opt out of auto enrolment.
Your employer must give you the contact details for the pension provider if you ask for them.
You need to complete and sign the pension scheme opt out form, and return it to your employer (or the address given on the form).
The pension provider might allow you to opt out online.
If you opt out of the scheme within one month of being automatically enrolled, you’ll be treated as if you had never joined the scheme. Any money that you’ve paid in will be refunded in full.
You’ll only get back the contributions you’ve made. You won’t get the contributions your employer might have made, or any tax relief.
If you decide to opt out more than one month after you’ve been set up in your employer's workplace pension, any contributions you’ve made will usually be held in the scheme. This will be until you can begin taking the money out of your pension pot when you retire.
This is unless the pension scheme’s rules allow your own contributions to be refunded.
You can’t usually start taking money from your pension pot until you’re aged 55 or over. This rises to age 57 in 2028.
