Data Coverage & Methodology

Primary portal for all above-threshold UK procurement. Covers Northern Ireland above-threshold contracts. Scottish above-threshold contracts also appear here.

English portal for below-threshold contracts not appearing on Find a Tender. Includes NHS, councils, arm's-length bodies and central government departments.

All Scottish public sector including Scottish Government, NHS Scotland, all 32 councils, universities, and other Scottish bodies.

All Welsh public sector including Welsh Government, NHS Wales, all 22 Welsh councils, and other Welsh public bodies.

Northern Ireland public sector portal covering NI departments, councils, health trusts and other public bodies. PSIP collects recently published notices from the portal’s public notice feed; the portal’s full historic search is access-restricted, so older or below-feed notices may not always appear. NI above-threshold contracts also appear on Find a Tender.

Official government sources

PSIP connects directly to the official government APIs for Find a Tender, Contracts Finder and Public Contracts Scotland, and collects Sell2Wales and eTendersNI notices directly from their official public procurement portals. Every source is a first-party UK government publisher — never a third-party reseller or aggregator.

Daily refresh

Our pipeline runs daily, pulling all new and updated notices from each source. Tender status changes (active → closed → awarded) are updated as they appear in the source data.

Deduplication

Contracts that appear on multiple portals (e.g. a Scottish contract appearing on both Find a Tender and PCS Scotland) are deduplicated by source reference ID to avoid double-counting.

Spending data ingestion

Supplier-payment transparency files (central-government £25k releases and council payments-to-suppliers publications) are collected on each body’s publication cycle, parsed through a single validating pipeline, and linked to Companies House where a registered company can be identified. Where a publisher blocks automated collection, files are retrieved manually and loaded through the same validated pipeline.

Data enrichment

Where available, we enrich tender records with Companies House supplier data, NHS ODS buyer data, and GIAS education establishment data to improve buyer intelligence accuracy.

AI scoring

AI relevance scoring uses Anthropic Claude to evaluate each tender against your specific business profile. Scores are calculated at search time — not cached — so they always reflect your current profile.
