"Voluntary benefits" is the name given to a collection of benefits that employees choose to opt-in for and pay for personally, although as with flex plans, many employers make use of salary sacrifice schemes where the employee reduces their salary in exchange for the employer paying for the perk. These tend to include benefits such as the government-backed (and therefore tax-efficient) cycle to work, pension contributions and childcare vouchers and also specially arranged discounts on retail and leisure vouchers, gym membership and discounts at local shops and restaurants (providers include Xexec). These can be run in-house or arranged by an external employee benefits consultant.
