Service Overview

When off-the-shelf SaaS subscriptions cannot support your proprietary workflows, forcing your staff to juggle disconnected spreadsheets and manual data entry, a bespoke web application becomes your strongest competitive moat. At 360 Web Coders in Wallington, Surrey, our web app development team architects and engineers secure, browser-based software systems tailored to British enterprises and high-growth SMEs. We build client self-service portals, field-service scheduling systems, underwriting and compliance platforms, supply-chain portals, and real-time analytics dashboards using React, Next.js, Node.js, Laravel, Python, and PostgreSQL. Every web application is engineered with granular Role-Based Access Control (RBAC), SSO and SAML enterprise login, real-time WebSocket updates, offline-capable PWA workers, and full UK GDPR audit logging hosted on UK cloud infrastructure across Britain.

Web App Development FAQs

Clear answers on UK custom web application costs, development timelines, security compliance, and cloud hosting.

Custom web app development in the UK costs between £8,500 and £20,000 for focused internal workflow tools or client portals, £20,000 to £50,000 for multi-role operational platforms with external API integrations, and £50,000 to £120,000+ for large-scale enterprise systems.

A Phase 1 production web app or core operational portal takes 6 to 10 weeks to deliver, while complex enterprise web applications take 12 to 24 weeks. Using agile two-week sprints, we often deploy core modules to your team within the first 6 weeks.

Yes, our data engineers write automated ETL (Extract, Transform, Load) migration scripts to clean, validate, and import historical records from legacy SQL databases, Microsoft Access, CSV spreadsheets, or outdated third-party CRMs with zero data loss.

We engineer every web app in alignment with UK Cyber Essentials Plus, ISO 27001 controls, and OWASP ASVS standards, implementing OAuth2/OIDC authentication, MFA, field-level encryption, strict RBAC, and UK-resident cloud databases.

No. Unlike off-the-shelf SaaS tools that charge per seat every month, you own 100% of the custom web app intellectual property and can add unlimited staff, suppliers, and customers at zero licence cost.
