    Methodology & coverage notes (96 active published awards)
    Coverage: 96 active published awards; 33 bid reports (which may be per lot); 0 valued awards. Supplier values exclude multi-supplier awards, frameworks and DPS, and use GBP only. They are published award values, not payments. Published-to-award variance compares single-lot, single-award, single-supplier GBP procedures with explicitly non-framework/non-DPS status; increases remain in the average. 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 Unpublished data stays unknown.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.
