UK app development pricing by type
MVP / Validation app — £15,000–£35,000
Single platform (iOS or Android), 6–8 core screens, basic auth and payments, Flutter or React Native. Suitable for validating your idea before committing to a full build. Delivery: 8–10 weeks.

What affects the cost?
- Native vs cross-platform: Native iOS + Android costs 40–60% more than Flutter/React Native cross-platform
- Backend complexity: Simple API vs real-time features vs complex business logic
- Integrations: Payment gateways, maps, camera, biometrics each add scope
- Compliance: FCA, PCI-DSS, NHS DSP, ISO 27001 add significant development overhead

London vs rest of UK
London app development typically costs 15–25% more than other UK cities due to higher salaries and office costs. However, London agencies often have deeper expertise in fintech, healthtech, and regulated industries. Meridian prices all app development 40% below the London market average — our MVP tier starts at £9,990.
How to reduce costs without cutting corners
- Start with one platform, not two — validate first, expand later
- Use cross-platform (Flutter or React Native) unless you need deep native features
- Launch with core features only — over-scoping is the #1 cause of budget overruns
- Use a design system from day one — it speeds up both development and future iterations
- Choose a fixed-price engagement over time-and-materials to cap your risk
