Methodology & coverage notes (11 active published awards)
Coverage is authority-wide (all CPV divisions): 11 active published awards; 4 bid reports (which may be per lot); 8 valued awards. Supplier values exclude multi-supplier awards, frameworks and DPS, and use GBP only. They are published award values, not payments. Award vs estimate uses the median of single-lot, single-award, single-supplier GBP procedures with explicitly non-framework/non-DPS status. Every figure carries an evidence level: Robust (5+ observations), Moderate (3–4), Indicative (1–2). Unpublished data stays unknown. Awarded suppliers are winners, not all bidders.
Direct historical sourcing (5 vendors)
Single-supplier GBP awards retained for this authority in the rolling 24-month window (excludes multi-supplier frameworks and DPS call-offs where attribution is unclear).
