The firm behind the work
Arallium is a specialist user-centred design consultancy for Caribbean public sector digital transformation. We work directly with governments and ministries, and embed as specialist UCD partners within larger consultancy and delivery teams — Big 4, systems integrators, and digital agencies working across the region.
Our work spans eight public sector domains: Education, Digital Identity & Civil Registration, Healthcare, Taxation, Social Protection, Customs & Trade, Climate Resilience Services, and Immigration & Border Services. All delivered to GDS standards. All grounded in user research with the people who actually use these services.
We are proud to be an Anglo-CARICOM business. Our Caribbean heritage is a genuine differentiator — we understand the policy context, the institutional landscape, and the citizen realities of government across the region in a way that few consultancies can claim.
Proven delivery across UK government
Our experience is grounded in direct delivery on large-scale UK government digital programmes — applying GDS standards across education and tax administration. The same rigour, brought to Caribbean public services.
Department for Education — £25m school digital infrastructure programme Current · Feb 2026
Leading interaction design on the DfE's £25m capital grant scheme upgrading network infrastructure across 4,000+ eligible schools in England. Full GDS agile lifecycle — Discovery service blueprints, ecosystem maps, stakeholder analysis. GOV.UK Design System and WCAG 2.1 AA applied throughout. Delivered a working Power Pages portal prototype with complete user journeys, task flows, and screen flows, handed to development ready for build.
This is precisely the scale and complexity of digital programme that Caribbean ministries of education are now commissioning — backed by IDB and World Bank investment. Arallium brings that delivery experience directly to the region.
HMRC — Digital Application Support Services Nov 2024 – Feb 2026
Interaction design across 87 live HMRC services — a mix of legacy and GDS-built — covering PAYE, Corporation Tax, VAT, Stamp Duty, Self Assessment, and multiple other tax disciplines. Full user journey prototypes designed and coded in HTML and CSS. In-depth user research conducted across multiple prototype iterations.
This depth of direct experience — how HMRC designs, tests, and operates taxpayer-facing digital services — is the foundation of Arallium's taxation sector specialism and informs our approach to every Caribbean revenue authority engagement.
HMRC — Enabling Multiple Agents Jul – Oct 2024
Designed and delivered a fully functional dashboard for secondary agents submitting clients' Self Assessment returns. Full GDS Discovery → Alpha → Beta → Live lifecycle. Prototype coded in HTML and CSS and tested with users across multiple iterations.
Accenture Song, Motorola, Vanquis Bank & major technology clients 2019 – 2024
Creative direction and senior UX leadership across Google, Lenovo, Cisco, Sage, Canon, Toshiba, and Orange — managing research, design, prototyping, and testing across large-scale digital platforms. Senior UX squad leadership at Vanquis Bank across credit, savings, vehicle finance, and loans journeys. UX design for Motorola's Ava Aware Cloud, managing over 1,000 workflows and 10,000 screens within a complex machine learning environment.
Eight domains. One standard.
Every sector Arallium works in is where Caribbean governments are actively investing in digital transformation — and every engagement is delivered to the same GDS standard we apply across UK government.
Education
School admissions, examination platforms, teacher and student-facing services, and ministry digital transformation. Grounded in direct delivery on the DfE's £25m school digital infrastructure programme across 4,000+ schools. IDB and World Bank are jointly investing $512m in Caribbean education digital transformation.
Digital Identity & Civil Registration
The foundation every other digital service depends on. Active World Bank programmes in Dominica, SVG, and Jamaica — digital ID, civil registry, and vital statistics modernisation. Our GDS experience in identity-adjacent services positions us directly for this work.
Healthcare
Patient-facing services, health information systems, electronic patient records, and clinician tools — designed with the rigour life-sensitive services demand. IDB-backed Pan-American Highway for Digital Health is creating a common regional ecosystem.
Taxation
18 months of direct HMRC delivery across 87 live tax services — PAYE, Corporation Tax, VAT, Self Assessment, Stamp Duty — applied to Caribbean revenue authority digital transformation. A depth of tax digital experience that no other Caribbean UCD consultancy holds.
Social Protection
Benefits, conditional cash transfers, and welfare services are among the highest-stakes citizen-facing journeys in the Caribbean — and among the least user-centred. World Bank adaptive social protection programmes are creating direct demand for this expertise.
Customs & Trade
IDB-funded customs modernisation is active across CARICOM. Trader-facing portals, single window systems, and customs authority internal tools — each requiring the same GDS-standard service design we bring to every engagement.
Climate Resilience Services
A Caribbean-specific imperative. Hurricane Melissa caused damage equivalent to 41% of Jamaica's 2024 GDP. IDB's Ready and Resilient Americas programme (2025–2030) is creating demand for citizen-facing digital disaster services — early warning interfaces, relief applications, emergency registration — that almost no consultancy is yet designed to serve.
Immigration & Border Services
CBI programmes under ECCIRA regulatory reform, CARICOM free movement, e-passport rollouts, and border agency digitalisation — high-stakes, complex, multi-party journeys in urgent need of user-centred design.
The GDS process, applied to the Caribbean
The same process we apply on UK government contracts — adapted to the institutional context, citizen realities, and connectivity constraints of Caribbean public services.
Discovery
Service blueprints, ecosystem maps, stakeholder analysis, and contextual research with the people who use and operate the service. We surface what a service is actually like before a single screen is designed.
Design
GOV.UK Design System components adapted for Caribbean contexts. Prototypes coded in HTML and CSS using the GOV.UK Prototype Kit — tested with real users before any build commitment is made.
Delivery
Embedded alongside developers and policy leads. WCAG 2.1 AA accessibility compliance assured. Complete user journeys, task flows, and screen flows handed over to development with full documentation.
The limits of in-house user-centred design
Many governments now invest in building UCD capability in-house. This is welcome — but in practice, in-house teams frequently lack the cross-sector pattern recognition, methodological depth, and peer challenge that sustained quality requires. Budget pressures mean this capability is often the first to be cut before it properly embeds.
Arallium's role is to complement and strengthen in-house teams — bringing cross-sector GDS expertise and Caribbean contextual knowledge that accelerates capability transfer and reduces delivery risk. We leave organisations with more capacity than we found them with.

Government ministry, consultancy seeking a specialist UCD sub-partner, or development finance organisation — we welcome the conversation.
