Warrington is a sub-ICB location. Choose “Sub-ICB locations” to find it. The main series uses NHS England’s current-footprint data, with historical figures mapped by the publisher.
Quarterly history, side by side
All 37 published quarters are included. Historical figures are mapped to the current geographical footprint by NHS England. They can differ from the original quarterly workbooks.

A “small count” label means fewer than 100 completed assessments. This is a project caution marker, not an NHS threshold. Small counts can produce large percentage changes.
Understanding and updating the figures
What is being measured?
Standard CHC assessments recorded as eligible ÷ completed Standard CHC assessments × 100. Counts come from the official combined time-series CSV: fields “AssdEligibleStd” and “AssmtsComplStd”, checked against the publisher’s metadata. The equivalent original workbook columns are Z and T in “1.3 In Quarter”. Percentages are calculated from the counts and rounded to one decimal place. A zero denominator is shown as unavailable.
The England figure is the published national total, not an average of area percentages. It includes the areas selected for comparison. Differences are percentage points, calculated before rounding.
What can affect comparisons?
Case mix, referral and assessment practices, documentation, data quality and organisational boundaries may affect results. No adjustment for these factors has been made. These are assessment counts, not a cohort tracking unique people, and are not the proportion of all people needing care who receive funding.
The combined source maps all quarters to 36 ICBs and 106 sub-ICB locations. NHS England uses apportionment based on registered GP populations when boundaries change. These mapped historical figures are not necessarily the exact counts originally reported by the present-day organisation. Original quarterly workbooks are retained in the source catalogue below. The earlier prototype used the original structures; this release consistently uses the mapped series.
The COVID-19 period affected CHC assessment arrangements. Interpret results during 2020/21 in that context; a recorded zero is not a substitute for missing data, and a zero denominator produces no percentage.
How will updates work?
This is a versioned release; it does not fetch live data when you open the page. A scheduled release check looks for new quarters and revisions. Publication follows validation: retain the combined CSV, metadata and original aggregate workbooks; check reporting periods, definitions and mapping; and reconcile non-overlapping ICB and sub-ICB totals separately to England. Updates require a checked release, so a new NHS publication will not appear here immediately.
Review local spot checks and boundary changes before publication. Record the source filename, SHA-256 checksum, release date and corrections. Keep previous versions. Never silently combine the aggregate collection with the replacement All Age Continuing Care Data Set (AACCDS).
NHS England announces retirement of the aggregate collection after Q4 2026/27 and a parallel AACCDS publication with known completeness and quality issues during transition. Reassess comparability before switching sources.

NHS England: CHC and FNC quarterly data and transition notices ↗
Version 1.1, 15 October 2026: expanded to all 37 quarters in the official combined file, April–June 2017 to April–June 2026. Retained all 37 original quarterly workbooks plus the combined CSV, national time-series workbook and metadata (40 files). Version 1.0 used three snapshots on the original geography. Three continuing organisation codes in each earlier snapshot have changed mapped counts; 13 former codes are absent from the current series. These are geographical-series differences, not evidence of incorrect original reporting. Historical figures remain subject to NHS revisions.
