Aim of this survey

The Occupational Pension Schemes Survey (OPSS) collects information from pension schemes about scheme membership, benefits and contributions and includes sections on very small schemes (schemes with 2 to 11 members) and those that are winding up. The OPSS covers both private and public sector occupational pension schemes registered in the UK. Results from the OPSS provide a detailed view of the nature of occupational pension provision in the UK. This includes membership of schemes, the nature of the benefits provided and contributions paid.

The results are used by government departments (for example, the Department for Work and Pensions, HM Revenue and Customs), regulatory bodies (for example, The Pensions Regulator, the Financial Services Authority), trade unions, trade associations and industry bodies (for example, the Association of British Insurers, the National Association of Pension Funds), charities, research institutes (for example, the Institute of Fiscal Studies) and others such as the National Employment Savings Trust Corporation.

Survey information

Selection criteria: The Pension Scheme Register, maintained by The Pensions Regulator, is used as the sampling frame. The frame covers all occupational pension schemes in the UK with two or more members.

Population: approximately 45,000 occupational pension schemes

Sample: approximately 1,600 schemes – 1,400 private, 200 public

Frequency: annual

Despatch date: between 5 and 7 September

Return-by date: between 4 and 6 October

Despatch and return-by dates are a guide. They are subject to change due to national holidays and weekends.

Why you have received this survey

You have been selected as an occupational pension scheme with two or more members.

Selection for this survey is determined by a stratified sample, taken from the Pension Scheme Register, with scheme membership and sector (public or private) used as stratification variables. Scheme membership refers to total membership – that is, active members, pensioner members and those with deferred entitlements.

Pension schemes with more than 5,000 members are always included in the sample and stratified sampling is used for schemes with fewer than 5,000 members.

The OPSS is conducted under the provisions of the Statistics of Trade Act 1947. Once selected, your business is legally obliged to comply. You cannot appeal your selection.
