Triennial activities, automatic enrolment and valuation

What is triennial automatic enrolment? 

Automatic enrolment is a government initiative to help more people save for later life through a pension scheme at work. It requires employers to enrol their eligible workers every three years into a pension scheme automatically and to pay towards their pensions. 

For the purpose of automatic enrolment, workers are put into three different categories depending on how much they earn and their age. The categories are:

  •  eligible jobholders
  • non-eligible jobholders
  • entitled workers

Automatic enrolment will mainly affect eligible jobholders.  

As a payroll provider, it is your duty, and the scheme employer’s responsibility, to ensure that all workers are assessed properly and are automatically enrolled into the LGPS where appropriate. The next triennial automatic enrolment is in August 2025. You will be expected to send completed automatic enrolment information to Hampshire Pension Services as part of this process. 

The Employer Team at Hampshire Pension Services will be able to help you make sense of auto-enrolment. Read their auto-enrolment guide and contact them for more information using the employer hub.

What is a triennial actuarial valuation? 

An actuarial valuation is carried out every three years as required by LGPS regulations to assess the ongoing financial position of the LGPS fund and its employers and sets the contribution rates payable for the next three years. 

As a payroll provider, you must ensure that your scheme employer’s annual returns and all contribution submissions are made on time and are accurate because these details are a factor in the triennial evaluation.

Hampshire Pension Services offer Annual Return Workshops each year to all scheme employers and payroll providers to talk through:

  • the requirements
  • the timetable
  • the Annual Return template and processes for query resolution
  • how to calculate some of the information that goes into the spreadsheet
