Flutter & React Native Apps in the UK

For most business-to-business services supplied from outside the UK, the reverse charge applies: you account for the VAT in your own return rather than paying it to us, and it is typically neutral if you are fully recoverable. Our invoices state the position clearly so your accountant is not guessing. If your situation is unusual, for example partial exemption, we would rather your accountant confirms the treatment before we invoice than after.

We build to it rather than claiming a certificate. In practice that means data minimisation designed in rather than bolted on, a documented lawful basis for each processing activity, retention periods that actually delete, subject access and erasure handled as features rather than manual database work, and hosting in a region you approve. Where we process personal data on your behalf we sign a processor agreement setting out exactly that.

Yes, and it is scoped from the start because retrofitting accessibility is considerably more expensive than building it in. We work to WCAG 2.2 AA, test with a screen reader rather than relying on an automated scan, and produce the accessibility statement the regulations require. Automated tools catch perhaps a third of real issues, which is why the manual pass is not optional.

We are happy to contract under English law with the courts of England and Wales, and most UK clients prefer that. IR35 does not apply to us: it governs individuals working through an intermediary, and you are engaging a company for a defined deliverable rather than a person for their time. Your accountant will want to see that the contract reflects that, and ours does.

MVP apps (5-10 screens, basic features): £710-£1,300. Production apps (25-50 screens, real-time, payments): £1,300-£3,600. Enterprise / multi-module apps: £3,600+. Final cost depends on screen count, native module needs, and whether the backend is already built or needs to be built alongside.

Flutter wins for: visual polish, 60fps animations, identical iOS/Android look, teams comfortable with Dart. React Native wins for: faster ramp-up if your team knows React, code sharing with a web app, larger npm ecosystem. We use both, pick based on team and design needs, not framework hype.

MVP apps: 8-12 weeks. Production apps with backend: 12-20 weeks. Enterprise apps: 20-40 weeks. Add 2-3 weeks for App Store and Play Store review on top of dev time. We work in 2-week sprints with TestFlight / Internal Testing builds every Monday.

Yes. App Store submission is included in every project, App Store Connect setup, screenshots in all required device sizes, privacy policy, content rating, and the review submission. We handle App Store reviewer questions and resubmissions if anything is rejected. Play Store is straightforward and similar.

Yes. Mobile apps need ongoing care, iOS and Android version updates each year, framework upgrades, dependency security patches, store policy changes. Our retainers run £180-£890/month depending on app complexity and feature roadmap. Most clients stay on retainer for 2+ years.
