The rate of contributions paid by employees who are members of the Local Government Pension Scheme is prescribed in Regulation 3 of the Local Government Pension Scheme (Benefits, Membership and Contributions) Regulations 2007 (SI 2007 No 1166, as amended).
The rate of contribution paid by employers who participate in the Scheme is determined at each triennial valuation, the last being in March 2007. Details of contribution levels for each individual employer are not held centrally but a summary of recent triennial valuation exercises undertaken by the Society of County Treasurers can be found at:

Individual Scheme administering authorities can provide details of contribution levels.
