United Kingdom Product & Engineering Division

Custom Web app development UK Web App Design
Company for the
United Kingdom.

Software built for the UK market carries obligations most templates ignore: lawful data handling under UK GDPR, accessibility that stands up to scrutiny, and often a requirement to keep data in UK or EU regions. We design and engineer web applications on React and Next.js with those constraints treated as architecture decisions rather than a compliance review at the end.

How We Work Here

What UK Web App Projects Actually Need

UK GDPR designed into the data model

Lawful basis, retention periods, subject access and deletion handled in the schema and the admin tooling, so a data request is a feature rather than a scramble.

Accessibility to WCAG 2.2 AA

Keyboard navigation, focus order, contrast and screen-reader semantics built into the component library — which matters commercially as soon as you sell to the public sector or a large enterprise.

UK or EU data residency

Hosting in London or EU regions with documented sub-processors, decided before the architecture is fixed rather than renegotiated during procurement.

Procurement-ready documentation

Security questionnaires, data flow diagrams and sub-processor lists prepared as part of delivery, because UK enterprise and public-sector buyers will ask for all three.

Open Banking and UK payment rails

Stripe, GoCardless, Direct Debit and Open Banking integrations where the product calls for them, including the mandate and reconciliation flows around them.

Source code and infrastructure you own

Repositories, cloud accounts and deployment pipelines in your company's name, handed over in full at the end of the engagement.

UK web app questions

Questions we get asked

Something not covered here? Ask us directly — we would rather answer it before you commit than after.

How do you handle UK GDPR in the build?

Lawful basis, retention periods, subject access and deletion are handled in the data model and the admin tooling, so a data subject request is a feature of the product rather than a scramble.

Do you build to accessibility standards?

Yes — WCAG 2.2 AA, with keyboard navigation, focus order, contrast and screen-reader semantics built into the component library. It matters commercially as soon as you sell to the public sector or a large enterprise.

Can data be hosted in the UK?

Yes — London or EU regions with documented sub-processors, decided before the architecture is fixed rather than renegotiated during procurement.

Can you help with security questionnaires?

Security questionnaires, data flow diagrams and sub-processor lists are prepared as part of delivery, because UK enterprise and public-sector buyers ask for all three.

Which UK payment rails can you integrate?

Stripe, GoCardless, Direct Debit and Open Banking where the product calls for them, including the mandate and reconciliation flows around them.
