CPI meaning

What does CPI mean?
In legal practice, CPI is the inflation benchmark most often used to index contractual sums (for example, rents, service charges, price‑adjustment clauses, maintenance, and periodic payments) and to inform damages calculations. It tracks average changes in the prices of a representative basket of consumer goods and services. CPI is not a term of art but a statistical series. In the UK it is compiled and published monthly by the Office for National Statistics (ONS); in Ireland it is published by the Central Statistics Office (CSO). Various statutes use CPI (or related indices) to uprate sums, but in private instruments it is a descriptive expression and should be tied to the precise series intended. Key drafting points: - Specify the jurisdiction and publisher (e.g., UK CPI (All Items) by ONS, or Irish CPI (All Items) by CSO). - State the measurement method (index-to-index or 12‑month percentage change), timing, rounding, and any caps/floors. - Include a rebasing/changes clause and a fallback if the index is altered or discontinued. Distinguish CPI from RPI (a legacy UK measure) and from UK CPIH (which includes owner‑occupiers’ housing costs). Usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland.

Statutory minimum increases and revaluation for occupational pensions: LPI caps, CPI/RPI changes, pre-1997 indexation and money purchase exceptions

Statutory minimum increase rates The summary below sets out the current statutory minimum uplift that occupational pension schemes must apply each year to each tranche of pension. Period of pensionable service to which the pension relates (or, for money purchase benefits, the period in which contributions were paid): Before 6 April 1997 — no statutory minimum increase. However, to refund surplus assets to a sponsoring employer under the Social Security Pensions Act 1975, s 58A, it was necessary (until 5 April 2006) to revalue all pensions in payment (excluding GMPs and money purchase benefits) annually in line with RPI, capped at 5%. Despite the absence of a statutory minimum, most defined benefit schemes provide some pre-1997 indexation under scheme rules or as a discretionary benefit. As at March 2023, research indicates that only 17% of members of private sector defined benefit schemes receive no pre-1997 indexation on benefits. There have been calls on the government to legislate to mandate inflation-linked increases to pensions...

Transparency International 2023 CPI: Global anti-corruption stagnates; UK score declines; US FEPA criminalises demand-side bribery; regional rankings highlight Nordic leadership and conflict-affected states’ struggles

Transparency International's 2023 Corruption Perceptions Index Transparency International’s 2023 Corruption Perceptions Index largely echoes previous instalments from the Berlin-based anti-corruption organisation, once more concluding that the majority of the world’s jurisdictions are stuck in a corruption-fighting rut and not moving forward at the pace hoped for. Gary Kalman, executive director of Transparency International US, told Law360 the results highlight the need to keep pressing these issues, as progress remains below expectations. The study assesses perceived domestic corruption in 180 countries and sets each on a 100-point scale, where higher marks indicate lower levels of corruption. Scores draw on datasets from 13 institutions, among them the World Bank and the World Economic Forum. The index captures a range of abuses, including bribery, political corruption, diversion of public funds, effective criminal prosecution of corrupt officials, and legal protections for whistleblowers. Denmark led this year with 90 points, retaining its title as the world’s least corrupt country for the sixth consecutive year. Nordic nations again clustered near the top, alongside Singapore, New...

England and Wales: Family Court fees rise 10% from 1 May 2024 under SI 2024/476; exemptions widened; divorce fee unchanged

What is the background to the increases? In the government’s response to its consultation on ‘Implementing increases to selected court and tribunal fees’, it stated it had decided to proceed with a 10% fee rise, in line with the CPI, covering 172 of the 202 fees it initially proposed. This approach keeps the uplift aligned with CPI inflation. The divorce application fee will stay the same, and 29 other fees will likewise not change while further analysis is undertaken. The government has also pledged to refresh fees on a two‑year cycle to account for variations in costs and CPI. The next scheduled review is planned for 2025–2026. Which court fees are increasing? The family proceedings fees that will increase are set out in full in Schedule 5 to the Court and Tribunal Fees (Miscellaneous Amendments) Order 2024, SI 2024/476 (SI 2024/476). By way of example, among others, the items listed below show the amount payable from 1 May 2024, with the current fee shown in brackets for...

Private sector occupational pensions: indexation and revaluation from RPI to CPI—statutory framework, scheme rule interaction, key case law, PPF/FAS impacts, and forthcoming alignment of RPI with CPIH

FORTHCOMING DEVELOPMENT : Section 10 of the Finance Act 2022 is set to lift the normal minimum pension age (NMPA) from age 55 to age 57, with effect from 6 April 2028, while members of the firefighters, police and armed forces public service pension schemes are excluded from the change. The Act further provides that members of registered pension schemes may draw benefits before 57 where, on or before 4 November 2021, they already held an ‘unqualified right’ to access benefits, or were already in the midst of a substantive transfer to a scheme that, on or before 4 November 2021, conferred an unqualified right to a protected pension age of under 57. To rely upon this protection in 2028, the scheme’s rules must, as at 11 February 2021, have expressly contained an unqualified right to take entitlement to scheme benefits before reaching age 57. For additional guidance, see Practice Note: Increasing the normal minimum pension age (NMPA) to 57—pensions impact...

Police Pension Scheme 2015 (England and Wales): statutory framework, funding and cost cap reforms, governance, eligibility, contributions, CARE design, benefits (retirement, ill‑health, death), transfers, appeals, and McCloud transitional remedy

FORTHCOMING CHANGE: The Home Office consulted on bringing the Police Pension Scheme 2015 revaluation date into line with the tax year—from 1 April to 6 April—to avoid CPI misalignment that can otherwise inflate annual allowance charges. Mirroring practice in other public sector schemes, the proposal seeks to improve fairness whilst leaving overall benefits unchanged. The consultation closed on 16 March 2026, with a response anticipated around June 2026. For more information, see LNB News 20/01/2026 39. Statutory framework There are currently three pension schemes in operation in England and Wales providing benefits for members of a police force. The three schemes are: the Police Pension Scheme 1987 (PPS 1987), which closed to new members from 6 April 2006 and to future accrual from 1 April 2022 the Police Pension Scheme 2006 (PPS 2006, or NPPS (the New Police Pension Scheme)), which also closed to future accrual with effect from 1 April 2022 the Police Pension Scheme 2015 (PPS 2015), which came into...
