Yorkshire Building Society

Yorkshire Building Society (YBS) is a UK mutual building society founded in 1864 and headquartered in Bradford, West Yorkshire. As a member-owned mutual rather than a shareholder-owned bank, it is owned by and run for the benefit of its savers and borrowers, with more than three million customers and around £66 billion in assets across the YBS Group, which trades under the Yorkshire Building Society, Chelsea Building Society (CBS), Norwich & Peterborough and Accord Mortgages brands. YBS is authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and the PRA as an FCA-authorised ASPSP. Although it is not one of the CMA9 banks mandated to build Open Banking, YBS is a voluntary participant in the UK Open Banking / PSD2 ecosystem and operates a public developer portal at developers.ybs.co.uk that documents its OBIE Read/Write API family - Account Information (AIS), Payment Initiation (PIS), Confirmation of Funds (CBPII), Event Subscriptions, Dynamic Client Registration, and token issuance - conformant to the Open Banking Implementation Entity (OBIE) Read/Write Data API Standard v3.1.2. Access to the production and sandbox surfaces (ob-ybs.api.ybs.co.uk / ob-che.api.ybs.co.uk and the matching sandbox hosts) is secured with FAPI-grade OAuth2/OIDC, PSD2 strong customer authentication, mutual-TLS transport authentication and PS256-signed JWTs, and is available to FCA-authorised third-party providers holding eIDAS/OBIE certificates.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/yorkshire-building-society: open an issue to ask a question, or submit a pull request to add artifacts.
