What SAIL Databank does

SAIL (Secure Anonymised Information Linkage) Databank is a Trusted Research Environment operated by Swansea University's Population Data Science department, founded as a pilot in 2007 following the launch of the Health Informatics Research Unit in 2006. It provides approved researchers, NHS organisations, and government agencies with secure remote access to anonymised, person-level health and administrative data spanning more than 25 years. SAIL curates data from over 500 organisations and maintains population-wide linkages across health, education, housing, justice, census, HMRC, social care, and environmental domains, holding billions of person-based records, with coverage having evolved from a Wales-wide resource into UK-wide infrastructure.

The platform is built on the Secure eResearch Platform (SeRP) and accessed via the SAIL Gateway, a VPN-authenticated remote desktop environment pre-loaded with R, Stata, Python, SAS, SPSS, and MS Office, plus SQL query tools. It uses a privacy-by-design split-file architecture in which Digital Health and Care Wales anonymises demographic identifiers before probabilistic record linkage, and applies sophisticated probabilistic matching methods at population scale. All data access proposals are reviewed by an independent Information Governance Review Panel (IGRP). The environment holds ISO 27001 certification, UK Statistics Authority accreditation as a trusted processor, Digital Economy Act 2017 accreditation, and Cyber Essentials certification, and was awarded the Queen's Anniversary Prize in 2023.

SAIL operates on a not-for-profit, cost-recovery basis. Core infrastructure is funded by the Welsh Government through Health and Care Research Wales and by the Economic and Social Research Council (ESRC), with estate costs channelled via Swansea University. Project-specific support services are charged under three pricing tiers (Standard Rate, Public Sector Rate, and Full Economic Cost for academic collaborations) on multi-year contracts, with no charge levied on projects that do not receive IGRP approval. Primary customer segments are academic researchers, NHS Wales health boards and trusts, and UK government and public-sector bodies; international academic users access the platform through approved collaborations.

Core offering

SAIL Databank is a Trusted Research Environment (TRE) operated by Swansea University that provides approved researchers with secure remote access to anonymised, linkable population-scale health and social care data spanning 25+ years. The platform supports probabilistic data linkage across NHS and non-NHS sources and enables population health research within an ISO 27001 certified and UK Statistics Authority accredited environment. It is funded primarily by the Welsh Government and operates on a not-for-profit, cost-recovery basis.

Product overview

SAIL Databank is a single, unified Trusted Research Environment (TRE) platform built on the Secure eResearch Platform (SeRP). The core offering is the SAIL Databank itself—a secure environment for accessing, linking, and analyzing anonymised population-scale health and administrative data. Researchers access the platform via the SAIL Gateway (remote desktop), with analytical tools (SQL, R, SPSS, STATA, Python) pre-installed. Supporting services include SAIL Teams analytical support, User Training, Packages (pricing tiers), and Public Insight (public involvement panel). The platform is ISO 27001 certified and UK Statistics Authority accredited.

Direct peers

• UK Biobank: Large-scale biomedical database and research resource holding health data from half a million UK participants. UK Biobank is comparable as a national-scale, accredited health data infrastructure serving academic researchers via secure remote access — though it focuses on consented cohort participants rather than whole-population linkage.
• Genomics England: UK government-established organisation operating a secure genomics research environment linked to the NHS. Genomics England runs a TRE-style platform for approved researchers, with comparable accreditations, secure researcher access models, and linkage of clinical and research data at population scale.
• ONS Secure Research Service: Office for National Statistics' Trusted Research Environment providing approved researchers with secure access to de-identified survey, census, and administrative data. Highly comparable in operating model, accreditation regime (DEA 2017), and TRE-based delivery for public-good research.
• Clinical Practice Research Datalink (CPRD): UK government-linked health data research service providing anonymised primary care records for observational research. CPRD is the closest direct analogue to SAIL in the UK, offering a similar TRE-style environment for population-scale health studies funded by the NHS and the Medicines and Healthcare products Regulatory Agency.

Emerging players

• NHS England Secure Data Environment: NHS England is rolling out a network of Secure Data Environments for NHS-held health and care data. Directly comparable as a federally-coordinated TRE model for NHS data, but at an earlier stage of maturity; a major potential competitor for grant funding and researcher mindshare.
• DATA-CAN: HDR UK health data research hub focused on cancer data. Comparable as a federated UK health data hub operating under similar governance standards; partnership-level peer via SAIL's involvement with multiple HDR UK research centres.
• PIONEER Health Data Hub: HDR UK-funded health data research hub focused on acute care and urgent care data in the West Midlands. Comparable as a TRE for population-scale NHS data but narrower in dataset scope and region; an emerging direct competitor in the same UK research ecosystem.

Broad incumbents

• Health Data Research UK (HDR UK): UK-wide institute coordinating the health data research ecosystem, including the Innovation Gateway that features SAIL. Comparable as the broader umbrella for UK health data infrastructure; HDR UK influences funding and standards but is not itself a TRE operator in the same way as SAIL.
• Administrative Data Research UK (ADR UK): ESRC-funded partnership that includes ADR Wales (SAIL's sister programme). Comparable as a UK-wide research infrastructure for linked administrative data, sharing the same funding lineage and overlapping user base of academic and government researchers.

Others

• Secure eResearch Platform (SeRP): Technology partner providing the underlying secure infrastructure that powers SAIL Gateway. SeRP is an enabler/technology supplier rather than a competitor, but is comparable as a UK TRE technology provider now extending to other datasets and institutions.
