Each row preserves its published reading. The sample grew from 217 homes in August to 781 in September, so changes can reflect both market conditions and the different properties observed.

Data coverage

From the UK corpus to one Bristol reading

The index is a narrow, reproducible cut from a much larger research warehouse. Corpus scale is disclosed separately from the local sample so large row counts cannot be mistaken for Bristol supply.

Profiles geocoded

119,707 profiles with usable coordinates

Warehouse coverage spans 4 June to 15 August 2026. Profile counts describe the UK discovery corpus, not active supply in this market; every published index applies its own geography, freshness, duplicate and minimum-sample rules. Supporting cuts use the 1 September observation window; earlier monthly headlines remain unchanged in the series.

Methodology and publication notes

Upgraded Intelligence records date by date availability and pricing for active short let listings. The index takes the latest valid observation for each listing and calculates the unavailable share from the observation date through day 30 inclusive, a 31-date window.

  1. Fixed geography

    The same ten-kilometre radius around central Bristol is used for every release.

  2. Comparable calculation

    Each property contributes its most recent valid availability observation; duplicate and stale records are removed before aggregation.

  3. Availability boundary

    Unavailable nights may be booked, owner blocked or otherwise restricted. They are not confirmed occupancy.

  4. Price publication gate

    Unavailable percentages cover the whole tracked market. A nightly rate is published only when the separate professional price sample is broad enough to support it.

  5. Minimum sample threshold

    Dates with too few valid properties are excluded rather than estimated, protecting the integrity of the published average.
