Unlock deeper insight into the UK equity market with our daily short-selling data solutions. We provide full dashboards and API access to the dataset as disclosed by the Financial Conduct Authority's (FCA) Aggregate Net Short Positions (ANSP) framework, enabling you to closely monitor aggregate short positioning across all UK-listed reportable shares. Whether you are an institutional investor, quant fund, risk manager, or research team, our data gives you the transparency you need to understand how short interest evolves across the entire UK market.
Each working day from 12:00, the FCA publishes the current ANSP report for every company on the Reportable Shares List (RSL). We deliver this through our dashboatds and API:
- Aggregate Net Short Position as a Percentage of Issued Share Capital
- Latest Position Date (the date of the most recent individual notification contributing to the aggregate)
- Report Date (the date the FCA published the ANSP)

Our system ingests, normalizes, and quality-checks these values every day as they are published by the FCA, ensuring reliability and consistency across the entire dataset.
Clients can access the data via our dashboards and/or API, that delivers data in CSV, XML, and JSON file formats. This dataset is part of our broader suite of short-selling intelligence, including EU short disclosure feeds, Saudi Exchange aggregate short positions data, Australian (ASIC) short positions data, Sweden aggregate short positions data, Denmark aggregate short positions data, activist short selling data and analytics, and our retail investors popularity and sentiment datasets.
As a specialized data and analytics company, we help professional investors transform raw regulatory disclosures into actionable insights. If you're looking to incorporate UK short-selling activity into your models, dashboards, or risk engines, we offer the suitable solution.

The new UK Short Selling Regime (SSR 2025) — and what changed
From 13 July 2026, the UK operates under the Short Selling Regulations 2025 (SSR 2025), which replaced the previous regime inherited from EU law. This is a significant structural change that affects what is publicly disclosed and how. Understanding the differences is essential for anyone using short-selling data on UK equities.
| Feature | Previous regime (pre-13 July 2026) | New regime — SSR 2025 (from 13 July 2026) |
|---|---|---|
| Public disclosure threshold | Individual positions at or above 0.5% were publicly disclosed with the position holder's name. | Individual positions are no longer publicly named. Only the aggregate net short position per company is published — anonymised. |
| Notification threshold | Positions at or above 0.2% had to be notified to the FCA (privately); positions at or above 0.5% were also publicly disclosed. | Positions at or above 0.2% must be notified to the FCA. All notified positions feed into the published ANSP — but no individual names are made public. |
| What is publicly available | Named individual disclosures (≥0.5%). | The aggregate only (≥0.2%). Individual position holders are anonymised. Historical named disclosures under the previous regime remain archived. |
| Reportable shares | Based on the previous EU/UK framework. | Determined by the FCA's Reportable Shares List (RSL), updated periodically. All notifications must reference the RSL from day one of the new regime. |
| Publication timing | T+1 basis. | T+2 basis — individual positions from 2 working days earlier, reported to the FCA the day after the position was held. |
What this means for data users: Under the new regime, the ANSP is the only FCA public window into short positioning on UK equities. The named individual disclosure feed that existed under the previous regime — where funds above 0.5% were publicly identified — no longer applies under SSR 2025. Our API captures the ANSP as published daily by the FCA, making it the definitive source for monitoring aggregate short interest across UK-listed reportable shares going forward.
Historical named individual disclosures submitted under the previous regime remain available in the FCA's archive. For our historical named UK short position data covering the period up to 13 July 2026, see our separate UK Named Short Positions dataset.
Why the ANSP measure matters
The Aggregate Net Short Position published by the FCA shows the combined short interest across all notified positions in a given company:
| Measure | What it tells you |
|---|---|
| Aggregate % of issued share capital | The total short interest in the company as a percentage of its issued share capital, aggregated across all position holders who have notified the FCA at or above the 0.2% threshold. Individual positions are anonymised — only the sum is public. |
| latest_position_date | The date of the most recent individual notification that contributed to the published aggregate. Tracking this field tells you whether the aggregate has been updated by new activity or is carrying forward older positions. |
| date (report date) | The date the FCA published this ANSP. The dataset is published on a T+2 basis — positions from 2 working days earlier feed into the published figure on this date. |
Aggregate Net Short Position as a Percentage of Issued Share Capital (%)
This shows the total net short interest in a company across all notified positions, expressed as a percentage of its issued share capital, as published in the FCA's daily ANSP report.
Formula (conceptually):
Sum of all notified Net Short Positions (≥ 0.2%) / Issued Share Capital × 100%
Interpretation:
- A higher percentage means a greater aggregate short interest in the company across all notified position holders.
- Only positions at or above the 0.2% notification threshold are included. Sub-threshold positions are not reported to the FCA and therefore cannot appear in the ANSP — this is a structural feature of the regulatory framework.
- Because individual positions are anonymised under SSR 2025, the ANSP is the sole public indicator of short interest in UK reportable shares. Unlike the previous regime where named positions above 0.5% gave visibility into specific funds, the new aggregate-only structure means total short interest is visible but position-level attribution is not.
- The FCA may in exceptional circumstances delay or adjust inclusion of notifications while verifying accuracy. The ANSP always uses the most recent notification for each position holder where no update has been submitted on that day.
