Frequently Asked Questions

Next.js is almost always the better choice for UK business applications that need google.co.uk SEO, performance, or server-side data access. Plain React renders entirely in the browser — Next.js static and server components deliver faster TTFB, better Core Web Vitals, and stronger google.co.uk rankings. Only use plain React for fully authenticated dashboards where SEO is irrelevant.
Yes for UK government procurement and regulated sectors (banking, insurance, NHS-adjacent). WCAG 2.1 AA requires keyboard navigation for all interactive elements, ARIA labels on all controls, sufficient colour contrast (4.5:1 minimum), and visible focus indicators. All UK React builds from ARS Developer meet WCAG 2.1 AA by default.
A Next.js marketing site with headless CMS costs £5,000–£15,000. A React dashboard with Laravel API backend costs £12,000–£35,000. A headless Shopify Next.js storefront costs £15,000–£40,000. All pricing in GBP with milestone contracts.
Yes. TypeScript strict mode is mandatory on all UK React projects from ARS Developer. It prevents runtime type errors at compile time, enables better IDE tooling for larger teams, and provides the type safety that UK financial services and government clients require.

How We Work With UK Businesses

1 Book a Free Consultation

Tell us what the React front end has to do. We work with businesses across the UK, reply within one business day in UK hours, and will say up front if this is not the right approach.

2 Receive a Scoped Proposal

A written proposal covering component structure, state handling and API contracts, milestones and GBP pricing. Scope is fixed before work starts — no open-ended retainer.

3 Milestone-Based Delivery

The React front end arrives in reviewable stages. You approve each milestone before the next begins, so there is no large unreviewed handover at the end.

4 Launch and Post-Launch Support

We run the launch, monitor it afterwards, and hand over documentation another developer could pick up. Monthly maintenance is available, not compulsory.
