Federated Data Platform (FDP)

The NHS-scale data-integration platform run by Palantir under a £1.1bn / 7-year contract awarded in 2023 — "enough to run the NHS in England for two days." The vault's cleanest first look at a nation-scale federated-health-data-substrate for AI agents.

What it actually does

Two layers:

Back-office functions — trusts use the FDP for scheduling + records management + workflow (e.g., flagging when a patient is behind on cancer-treatment steps; letting staff schedule appointments; updating records).
Cross-trust federation — links different NHS data systems + structures so trusts can share innovations. Tom Bartlett (led the NHS team that developed the FDP) is "most excited" about this layer — cites watching a nurse and paramedic at a hackathon build a prototype tool in two days.

Bartlett's third framing (the load-bearing one for the vault): the FDP is what makes the NHS AI-ready — "the software provides a structured layer for ai agents or applications to run on."

Why this is a concept, not just an entity

The FDP is one specific contract, but the pattern — a federated-data substrate that AI agents can run on top of — is a generalisable pattern that the vault expects to recur across health systems (public + private), governments (defence, tax, welfare), and large enterprises. This is the substrate layer whose absence is what the vault's Agentic Flooding concept diagnoses as broken; the FDP is a positive-sum named counterpart.

The load-bearing controversies

The 110,000-operations figure was oversold

Palantir cited "110,000 additional operations in the 40-odd trusts using the software for in-patient scheduling" from the NHS's own dashboard.
But the figure did not disaggregate the software's effect — it included pandemic-backlog catch-up since 2020.
Britain's statistics watchdog reprimanded the NHS in July 2026 for using the figure without a caveat.
Louis Mosley (Palantir UK): "You can't say that the 110,000 operations only happened because of Palantir… directionally, it's very, very clear."

Health Foundation rebuttal

Report found that trusts using Palantir's discharge tool cut delays no faster than trusts that did not.

The uptake vs impact paradox

Mosley calls the low-utilisation situation a "volunteer army, not a conscript army" — most acute trusts have signed up but do not use it.
But Chelsea and Westminster trust (best FDP user for reducing waiting lists) still saw its waiting lists rise faster than almost any other's. So the software-usage → outcome link is weaker than either side claims.

The break-clause decision

February 2027 — an MP select committee has recommended Andy Burnham exercise the break clause.
Tom Bartlett: if Britain exercises the break, "it will be nigh-on impossible to find a consortium to replace Palantir before next February."

Why this page exists

The FDP is:

The vault's fullest first look at a nation-scale AI-agent substrate. Bartlett's "structured layer for ai agents" framing is what makes this substrate distinctive from ordinary enterprise-data-integration — the ontological work is what turns disparate NHS data into something agents can act on.
A test case for the tech-sovereignty vs vendor-competence tradeoff. The February 2027 break-clause decision is the live UK case study. If Burnham exercises it, the vault should watch for what replaces it (or what breaks). If not, the vault should watch for how the "privacy shield" framing evolves.
A pattern that will recur. The FDP is one contract; the pattern of federated-data-substrate + agent-layer will recur across governments and enterprises. Concept-page-worthy for that reason alone.
