1. Terms of reference of the Inflation Tetrapartite Group


The Inflation Tetrapartite Group will discuss inflation statistics produced or managed by Office for National Statistics (ONS), including consumer price statistics, producer price statistics, services producer price statistics, trade price statistics and housing price statistics.


The group provides a forum for discussing how well ONS’s range of price inflation statistics is meeting user needs, for sharing progress on current developments and for identifying areas for future development.

When required, the group will consider routine, operational requirements (such as annual basket reviews and VAT changes) that require advice in a timely manner to ensure that the quality of price statistics is maintained.


The Inflation Tetrapartite Group is not a decision-making body.

Proposals for change regarding the coverage or methodology underpinning consumer price inflation statistics are referred to the Advisory Panel on Consumer Prices (APCP) Stakeholder or APCP Technical, which are responsible for providing independent advice to the National Statistician on consumer price statistics.


The Inflation Tetrapartite Group comprises officials from the Bank of England, HM Treasury, the Office for Budget Responsibility and the Office for National Statistics (ONS).

The Head of ONS’s Prices Division will act as the chair.

Membership of the group is set out in Annex A, which will be updated as necessary.

Meetings schedule

The Inflation Tetrapartite Group will normally meet quarterly.
