What does it cost to build an app in the UK?
The cost of building an app in the UK typically ranges from £30,000 to £250,000+, depending on complexity, features, integrations and the team involved.
Building a mobile or web app in the UK can be a significant investment. Understanding the app development cost UK is essential whether you’re launching a new startup, expanding your business digitally, or creating a complex enterprise solution. In this blog, we’ll break down typical price ranges, key factors that influence cost and practical strategies to keep your project on budget.
App cost breakdown by complexity
| App type | Typical cost | Timeline |
|---|---|---|
| Simple (MVP) | £30,000 – £60,000 | 2 to 4 months |
| Medium complexity | £60,000 – £120,000 | 4 to 8 months |
| Complex / enterprise | £120,000 – £250,000+ | 6 to 12+ months |
Simple App (MVP)
Simple apps focus on core functionality with minimal features. These apps are ideal for testing an idea and getting user feedback. Expect development to take 2–4 months with costs between £30,000 and £60,000.
Medium Complexity App
These apps include multiple features, integrations, and custom design elements. Development usually takes 4–8 months and costs range from £60,000 to £120,000.
Complex / Enterprise App
Enterprise-grade apps include advanced functionality like AI, real-time data, and complex integrations. Development can exceed 12 months and cost £120,000 to £250,000+.

What affects the cost most?
1. Features and functionality
More features means more design, development and testing. Examples:
- User accounts
- Payments
- Real-time data
- AI functionality
2. Platform choice
- Native iOS and Android increases cost
- Cross-platform can reduce initial spend
3. Design complexity
Custom UX and behavioural design increase value but require more time.
4. Integrations
Connecting to third-party systems such as NHS APIs, CRMs or payment providers adds complexity.
5. Team structure
Costs vary depending on whether you work with:
- Freelancers
- Offshore teams
- UK-based product teams
Before committing your budget to a development partner, make sure you’ve asked the right questions — see our guide on the 10 Questions to Ask a Development Agency Before You Hire Them to assess fit and expertise. This ensures that your chosen team is aligned with both your budget and project goals.
How to reduce app development costs
You can manage your app development cost UK by following these strategies:
- Start with an MVP: Focus on the minimum viable product to validate your idea before building a full-featured app.
- Prioritize core user journeys: Avoid overbuilding features early in development.
- Validate ideas before scaling: Conduct market research and prototype testing to prevent wasted investment.
- Avoid unnecessary complexity: Stick to essential integrations and functionalities first.
This approach reduces upfront costs, speeds up development, and provides measurable insights for future improvements.
What is included in the cost?
A realistic budget should account for all phases of app development:
- Discovery & Strategy: Market research, project planning, and defining features
- UX/UI Design: Wireframes, prototypes, and visual design
- Development: Front-end and back-end coding, database setup
- Testing & QA: Functional, performance, and security testing
- Deployment: App store submission and release management
- Ongoing Support: Maintenance, updates, and bug fixes
