United Kingdom
Bespoke web applications for UK businesses in London, Manchester and Birmingham — GDPR-compliant architecture, Open Banking, HMRC MTD and Companies House integration built in from day one.
Definition
Web application development for UK businesses means building bespoke interactive software — B2B SaaS platforms, client portals, marketplace apps and internal tools — built to UK GDPR compliance, ICO standards and UK data residency requirements, not adapted from a US-first template or no-code tool.
For UK companies this means web applications that store data on AWS eu-west-2 (London) for GDPR compliance, integrate natively with Companies House, HMRC Making Tax Digital and Open Banking APIs, support UK payment gateways (Stripe UK, GoCardless) and are pen-tested against OWASP Top 10 — requirements that website builders and no-code platforms cannot satisfy.
Website builders and no-code tools hit their ceiling long before the requirements of a growing UK business.
Webflow, Bubble and WordPress cannot handle complex UK business logic — multi-role workflows, real-time data, and custom approval chains require a properly engineered web application
US-hosted no-code platforms create ICO compliance risk — UK GDPR requires documented data residency and transfer impact assessments that generic SaaS platforms do not provide
HMRC Making Tax Digital, Open Banking and Companies House API integration are not supported by website builders — they require a custom-built application with proper API architecture
Performance: website builder platforms share infrastructure and cannot guarantee the Core Web Vitals scores your UK SEO ranking depends on — or the uptime your customers expect
What We Build
Built to UK compliance standards from the ground up — GDPR, ICO, MTD, Open Banking and PCI-DSS.
Multi-tenant UK SaaS platforms with role-based access, subscription billing, Companies House API integration and GDPR-compliant data architecture — built to acquire customers and retain them through product depth.
Branded self-service portals for UK businesses — real-time access to jobs, invoices, reports and support. GDPR-compliant audit trails and ICO-ready data management included as standard.
Full marketplace web applications for the UK market — buyer/seller matching, Open Banking payments, FCA-aware transaction flows, PCI-DSS compliant checkout and vendor onboarding.
Custom UK back-office web applications replacing spreadsheets — workflow automation, approval chains, HMRC Making Tax Digital (MTD) integration, Xero/Sage/QuickBooks connectivity and audit trails.
Installable, offline-capable web apps that work on any UK device — push notifications, background sync and app-like UX at web distribution speed, without Apple/Google app store submission or fees.
Systematic rebuild of legacy UK web applications — PHP, jQuery and monolithic codebases onto modern Next.js, TypeScript and AWS cloud-native architecture with zero data loss and phased migration.

Our Process
We map your UK business processes, user journeys and compliance requirements — GDPR, ICO, Making Tax Digital or sector-specific regulation — before a line of code is written.
We define technical architecture, data models and UX. UK data residency (AWS eu-west-2 London), GDPR controls, Open Banking and HMRC MTD integrations are designed in at this stage.
Two-week sprints with working software at every cycle. No big-bang releases, no dark periods between milestones. Your UK team is included in every sprint review.
We handle deployment on UK-region infrastructure, monitoring and ongoing iteration. 90 days of post-launch support is included in every UK engagement as standard.

Web application development for UK businesses means building bespoke interactive software that runs in the browser — B2B SaaS platforms, client portals, marketplace apps and internal tools — built to UK GDPR compliance, ICO standards and UK data residency requirements. Cyberbeak builds custom web applications using Next.js, React and TypeScript, not website builder templates.
A focused web application with core features typically costs £25,000–£65,000 over 8–14 weeks. More complex enterprise platforms with multiple integrations, user roles and compliance requirements typically cost £70,000–£200,000 over 16–32 weeks. Cyberbeak provides fixed-scope, fixed-price proposals after a paid discovery sprint.
A focused MVP web application can be delivered in 8–14 weeks. Full enterprise web platforms typically take 16–32 weeks. We deliver working software in two-week sprint cycles — so UK clients see real progress every fortnight, not just at a big launch.
Yes. Cyberbeak builds web applications with UK GDPR compliance designed in from the architecture stage — consent management, data subject request workflows, privacy-by-design data models, AWS eu-west-2 (London) for UK data residency and ICO notification procedures.

Cyberbeak integrates UK web applications with Companies House API, HMRC Making Tax Digital (MTD), Open Banking (FCA-regulated), Xero, Sage, QuickBooks UK, Stripe UK, GoCardless, Twilio, Salesforce and other UK enterprise systems. We build native integrations, not brittle middleware connectors.
Yes. Cyberbeak builds PWAs that install on a user's device, run offline with service workers, and deliver push notifications — without app store submission fees or Apple/Google approval cycles. PWAs are ideal for UK businesses that need app-like UX at web distribution speed and cost.
