How Much Does Mobile App Development Cost in the UK?
Mobile app costs in the UK span £3,500 to £30,000+, driven mostly by complexity, not platform. Here’s an honest breakdown of what each tier delivers, what really moves the price, the App Store and running costs to expect, and where Codingclave sits versus UK agencies and offshore shops.
Price Tiers Explained
£3,500 – £8,000
Founders and SMBs validating an idea or launching a focused app.
- iOS + Android (cross-platform)
- Core feature set
- Auth + payments
- Store submission
- Analytics
£8,000 – £15,000
Businesses needing a complete, production-grade app.
- Polished UI/UX
- Push notifications
- Admin dashboard
- Third-party integrations
- Offline support
£15,000 – £25,000
Platforms with real-time features or marketplaces.
- Complex features (maps, chat, live data)
- Multiple user roles
- Scalable backend
- Deeper integrations
- Ongoing maintenance plan
£25,000+
Marketplaces, fleets and multi-sided platforms.
- Multi-app systems (e.g. user + driver + admin)
- High scalability
- Advanced security
- Custom infrastructure
- Full ownership
What Affects the Final Price
Feature complexity
Real-time data, maps, chat, payments and offline support each add engineering time. A simple catalogue app is a fraction of a live-tracking marketplace.
Number of apps & roles
A system with passenger, driver and admin apps is effectively three builds plus a backend, which is why platforms cost more.
Backend & scalability
Apps expecting high traffic need a robust, scalable backend, which adds cost up front but prevents painful rebuilds later.
Design polish
A bespoke, animated UI costs more than a clean standard one, but matters for consumer-facing apps competing on experience.
Costs Most Quotes Don't Mention
DIY vs Freelancer vs Agency
No-code app builders suit the very simplest internal tools but hit ceilings fast and still cost monthly. Freelancers (£2,000–£10,000) can deliver but the risk on a multi-month build is real if they disappear. UK agencies (£20,000–£80,000) bring strong process and accountability at premium prices. We deliver agency-grade apps — cross-platform, properly architected, with maintenance — at offshore-competitive pricing but with the communication and reliability of a local team, thanks to the strong UK–India overlap.
Codingclave vs Local UK Agencies
A standard app a UK agency quotes at £20,000–£35,000 typically lands at £8,000–£15,000 with us, built cross-platform on React Native or Flutter so iOS and Android ship together. You own the source code, get a maintenance option, and review builds throughout on TestFlight and Google Play internal testing. The saving is the delivery model, not the quality — same architecture, same store-ready polish.

Cost Questions
Yes — building one codebase with React Native or Flutter for both iOS and Android typically cuts cost and timeline by around 40% versus two separate native apps, with no meaningful downside for the vast majority of business apps.
Yes. We submit under your developer accounts (Apple £79/year, Google one-off ~£20) and manage the full review — listings, screenshots, privacy declarations and updates.
Budget for backend hosting (£20–£200/month) and ongoing maintenance for OS updates and fixes (£150–£600/month depending on complexity). Apps need upkeep as iOS and Android evolve.
Higher quotes usually reflect agency overheads or genuinely complex, multi-app platforms. For a standard business app, much of a UK agency’s premium is office cost, not engineering — which is exactly the gap we close.
Yes. On completion you own the full source code and store listings, so you’re never locked to us as the app grows.
