Auto-enrolment requires UK employers to enrol workers aged 22+ earning above £10,000/year into a workplace pension
Minimum total contribution is 8%: 5% from you (gross of tax relief), 3% from your employer
Opting out forfeits the employer match - effectively giving up free money equal to 3-10% of salary depending on the scheme
Above the auto-enrolment minimum, many employers offer matched contributions up to 5% or more - always max the match
