Mobile App Development Costs in the UK at a Glance

The cost to build a mobile app depends on what it needs to do and how it will be delivered. A simple app with a few screens is very different from a marketplace, delivery platform, booking system or app connected to an existing business database.

Simple App or MVP

£5,000–£15,000

A focused first version with essential screens, basic user flows and core functionality.

Business App

£15,000–£30,000

Suitable for apps with user accounts, dashboards, notifications and connected data.

Advanced App

£30,000–£50,000+

For multiple user roles, payments, complex workflows and third-party integrations.

Complex Platform

£50,000+

For larger marketplaces, on-demand platforms or apps with extensive backend requirements.

How Much Does Each Type of Mobile App Cost?

1. Minimum viable product (MVP)

An MVP focuses on the smallest useful set of features needed to test an idea with real users. It may include onboarding, a small number of screens, a simple database and basic analytics. Starting with an MVP can help you validate demand before investing in a larger product.

2. Small business app

A business app might let customers book appointments, view services, submit requests or receive updates. The budget depends on whether it needs login, a content management dashboard, push notifications, payments or connections to other business tools.

3. E-commerce or ordering app

Shopping and ordering apps often need product catalogues, search, basket and checkout flows, payment processing, order history, delivery updates and an admin interface. Inventory, delivery rules and payment integrations can add development and testing work.

4. Booking or service marketplace app

Booking and marketplace products may support customers, service providers and administrators. Features can include availability, scheduling, profiles, messaging, payments, reviews and dispute handling. Multiple user roles and complex workflows increase the scope.

5. Internal business or workforce app

Internal apps can support staff scheduling, attendance, task management, reporting or field operations. Costs depend on permissions, offline access, reporting, integrations and whether the app must connect securely to existing company systems.

What Affects Mobile App Development Cost?

Before estimating a project, identify the features and technical requirements that will shape the work.

  • Features and workflows: Every additional screen, user role and business rule needs design, development and testing.
  • iOS and Android: Building for both platforms affects scope. Cross-platform technology may help share code, but platform-specific work can still be required.
  • UI and UX design: Research, wireframes, prototypes, accessibility and custom interfaces influence the design effort.
  • Backend and database: Authentication, APIs, data modelling, file storage and admin dashboards add backend work.
  • Integrations: Payment gateways, maps, booking systems, analytics, CRM tools and external APIs need implementation and testing.
  • Security and privacy: Data access controls, secure authentication, backups and appropriate handling of personal information are important considerations.
  • Testing and release: Device testing, bug fixing, store listing assets and app review preparation should be included in the plan.
  • Ongoing support: OS updates, dependency updates, monitoring, bug fixes and new features can create recurring costs.

Should You Build for iOS, Android or Both?

Your audience and product requirements should guide the platform decision. A native app is developed specifically for a platform, while cross-platform frameworks can support iOS and Android from a shared codebase. The best approach depends on required device capabilities, performance, integrations, budget and future maintenance.

Android onlyProducts focused on Android users or a specific marketOne platform to prioritise initially
Cross-platformProducts targeting both iOS and AndroidShared code may reduce duplicated work, depending on the app
Native iOS and AndroidApps requiring platform-specific capabilities or optimisationMay require more separate development effort

Ongoing Costs After Your App Launches

The initial development budget is only one part of the total cost of owning an app. Depending on your architecture and service providers, you may also need to budget for:

  • Cloud hosting and backend services: Costs can grow with active users, data storage and traffic.
  • Third-party APIs: Maps, messaging, email, AI features and other services may have usage-based fees.
  • Maintenance: Bug fixes, operating system compatibility, security updates and dependency upgrades.
  • App store accounts: Apple and Google developer account requirements and fees may apply and can change.
  • Ongoing improvements: New features, analytics, UX improvements and support for business changes.

Ask your developer which recurring services are included, which are billed separately and who owns each account. The answer can make a meaningful difference to your long-term budget.

How to Reduce the Cost of Building an App

  • Define the core problem: Be clear about the user need the app should solve.
  • Prioritise essential features: Keep the first release focused and move non-essential ideas to a later phase.
  • Validate before building: Use sketches or a clickable prototype to test the flow early.
  • Choose technology carefully: Match the stack to your requirements, team and maintenance plan.
  • Prepare project materials: Clear user flows, content, brand assets and acceptance criteria reduce uncertainty.
  • Plan a phased roadmap: Launch a practical first version, learn from usage and invest in improvements based on evidence.
Useful tip: Ask for a quote that separates discovery, design, app development, backend, testing, release and maintenance. This makes the scope easier to compare and helps identify what can be delivered within your budget.

How to Choose a Mobile App Development Company

Look beyond the headline price. A reliable development partner should explain the proposed scope, technical approach, milestones and responsibilities in plain language.

  • Review relevant apps or portfolio examples.
  • Ask which platforms and devices are included in the quote.
  • Confirm ownership of the source code, app store accounts and project assets.
  • Check what testing, documentation and handover are included.
  • Clarify post-launch support, maintenance and third-party costs.
  • Agree milestones, payment terms and a process for scope changes.

Final Thoughts

The cost to build a mobile app in the UK depends on the features, platforms, integrations, design and support required. A focused MVP can help you validate an idea, while a more complex product needs a larger budget and a carefully planned delivery process.

Before choosing a developer, compare the scope, ownership terms, delivery milestones and ongoing costs, not just the initial quote. A clear plan gives you a better foundation for launching and improving your app over time.

Frequently Asked Questions

How much does it cost to build a mobile app in the UK?

As a broad planning estimate, a simple MVP may cost £5,000–£15,000, a mid-complexity app £15,000–£50,000, and a complex platform £50,000 or more. The actual quote depends on scope and requirements.

Is it cheaper to build an app for iOS and Android together?

A cross-platform approach can share some code between iOS and Android and may reduce duplicated work. The savings depend on the app's features, integrations and platform-specific requirements.

How long does mobile app development take?

Timelines vary with complexity, feedback, integrations and testing. A focused MVP generally takes less time than a multi-role platform. Ask for a milestone-based timeline after the requirements are defined.

What costs should I expect after launch?

Potential ongoing costs include hosting, third-party services, maintenance, security updates, developer account fees and future improvements. Ask which costs are included in the proposal.

Can I start with a smaller app and add features later?

Yes. A phased approach can help you launch the essential features first, collect user feedback and prioritise later improvements. The initial architecture should still allow for realistic future growth.

What should I provide to get an app development quote?

Share the app's purpose, target users, required platforms, essential features, any integrations, an approximate budget and your preferred launch timing. You do not need a complete technical specification to start a discussion.
