United Kingdom & Ireland covers 366 providers publishing 1,349 APIs. The description on the region page calls out a strong concentration in open banking, fintech, and RegTech, driven in part by the FCA’s open-banking mandate.
The leaderboard says something more interesting than that.
Who leads
| Provider | APIs | Composite | Band |
|---|---|---|---|
| Ordnance Survey | 12 | 67.2 | exemplar |
| Super Payments | 8 | 62.0 | strong |
| Xoserve | 4 | 60.6 | strong |
| Wordnik | 5 | 60.3 | strong |
| GSMA | 18 | 60.2 | strong |
| Moneyhub | 2 | 60.1 | strong |
| Reapit | 7 | 59.9 | strong |
| Goodlord | 3 | 58.9 | strong |
| Street.co.uk | 3 | 58.5 | strong |
| HMRC UK Tax Authority | 8 | 58.2 | strong |
| Electricity North West | 2 | 58.0 | strong |
| Fixflo | 1 | 58.0 | strong |
| EDF Energy | 3 | 57.1 | strong |
| UK Power Networks | 2 | 56.7 | strong |
One exemplar. Everything else is strong, in a tight band between 56.7 and 62.0.
Regulated utilities are the region’s signature
Look at what is actually in that table. Xoserve runs the central data service for Britain’s gas market. Electricity North West and UK Power Networks are regional electricity distributors. EDF Energy is a generator and supplier. HMRC is the tax authority. Ordnance Survey is the national mapping agency and the region’s only exemplar.
Six of the fourteen highest-scoring providers in the UK and Ireland are regulated infrastructure or government.
That is not a pattern seen in DACH, India, or the US cohorts, and it has a specific cause. Britain has spent fifteen years mandating data access as a regulatory instrument — Open Banking, Making Tax Digital, energy market data, open geospatial. When a regulator requires an organisation to publish machine-readable data on a schedule, the organisation ships an API whether or not it has a commercial reason to.
The result is a region where a distribution network operator with 2 APIs scores 58.0, and does so because someone made it.
The open banking cohort is quieter than expected
Given the region’s reputation, the fintech presence here is modest: Super Payments (62.0), Moneyhub (60.1). Both strong, neither exemplar, both with fewer than ten APIs.
Open Banking’s UK implementation is a standard rather than a product, which means the described surface tends to live with the standards body and the individual bank rather than with a headline platform. The mandate produced enormous integration activity and comparatively few high-scoring provider entries — the value accrued to the specification, not to a vendor.
PropTech is a genuine cluster
Reapit (59.9), Goodlord (58.9), Street.co.uk (58.5), and Fixflo (58.0) are four estate-agency and lettings platforms in the top fourteen. That is a real, unusually API-literate British software cluster serving a domestic market — and it is more visible here than in any other region profiled.
Takeaway
366 providers, 1,349 APIs, one exemplar, and six of the top fourteen are regulated infrastructure or government. The UK and Ireland’s described API surface is the product of regulatory mandate more than commercial pressure — which is why a gas-market data service and a national mapping agency outrank the fintechs the region is famous for.
