The change in the contribution rates will apply starting from the 1st of April 2018.
The new employer contribution rate will be 2% and the employee, 3%. The client will need to inform the employees about this change.
Employees won't be able to opt-out, however if they don't wish to pay contributions they can cease them from their online account or through Nest's 'Automated Telephone service'.
Please note that stopping contribution is different from opting out. Workers can only opt out within one calendar month of their enrolment and receive a refund of their contributions. After that time Nest will continue to invest their savings until they take their money out of NEST.
If the worker wants to restart their contributions they’ll have to be enrolled again.
