Mobile App Development Cost in UK

The mobile app development industry in London, UK, is growing rapidly. Many businesses are establishing their digital presence on the internet to reach a wider audience and face numerous challenges in the process. However, developing a mobile app is not an easy task and requires strategic planning and a development process. In this guide, we will discover the factors affecting the mobile app development cost in the UK in 2025. 

Market Statistics of Mobile App Development in UK

According to a report by Statista, the market cap of app development in the UK was $18.08 billion in 2024, and with a CAGR of 9.17%, it is expected to reach $30.40 billion in 2029. 

Types of Mobile Apps and Their Development Cost

[1] Native Apps

Native apps are one of the most widely used types of mobile applications. Native apps are designed and developed for a single platform only such as Android or iOS. Since these apps are made individually for a platform, they can easily utilize the hardware resources and provide maximum efficiency on the platform. The cost of developing native apps ranges between £7,748 to over £85,228 ($10,000 to over $110,000) per platform. Integrating advanced features such as AI and ML will increase the overall costs. 

[2] Web Apps

As the name suggests, web applications are websites that are highly responsive and optimized for mobile usage. Web apps can be accessed by a web browser and do not require any kind of download or installation. Businesses that do not require native apps or have budget constraints can opt for web applications. The cost of web apps ranges between £3,874 and £19,370 ($5,000 to $25,000).

[3] Cross-Platform Apps

Cross-platform apps are getting increasingly popular due to their single codebase for multiple platforms. Cross-platform apps are developed using a single codebase for multiple platforms, such as Android, iOS, and Web. These features reduce the overall costs of developing an application for individual platforms. React, ionic, and Flutter are among the popular frameworks for developing cross-platform apps. The development costs lie between £11,622 to £38,740 ($15,000 to $50,000).

[4] Progressive Web Apps

Progressive Web Apps, or PWAs, are apps that run on a web browser but work like a native mobile app. One of the best features of PWAs is that they can work offline due to service workers and often by utilizing the cache memory of the device. This type of app is ideal for businesses that have a limited budget and want to increase their mobile web presence. The cost of PWA development is between £7,748 to £23,244 ($10,000 to $30,000).

[5] Gaming Apps

Gaming apps are the most popular form of entertainment, besides video streaming and OTT apps. Gaming apps are made in 2D and 3D and require animations, 2D/3D modeling, sound designing, etc. The games can be either single-player or multiplayer, or both. The cost of gaming apps is very subjective and starts from £38,740 ($50,000) for a simple 2D game to over £309,921 ($400,000) for a high-end game. 

Factors Affecting Mobile App Development Cost in UK

[1] App Complexity and Features

App complexity is determined by the number of features it has. The more complex the app and the more features it has, the more it costs to develop in the UK. A simple and basic app with features like user authentication, a simple interface, and minimal functionality generally costs less than apps with advanced features such as payment gateway integration, etc. 

[2] Platform Choice

There are several platforms, such as Android and iOS, and it is necessary to determine the platform that you want your app to be on. Developing an app for an individual platform would cost much but would provide a better user experience and functionalities. Opting for a cross-platform development would cost less due to a single codebase being used to develop the same app for multiple platforms, but it might face compatibility issues. 

[3] UI/UX Design

UI/UX is something that defines the app and makes it unique and famous among users. An intuitive, fast, responsive, and beautiful user interface that requires custom animations and designs requires a significant amount of investment, which increases the overall costs. 

[4] Location and Expertise of the Development Team

The location of the development team also matters in determining the mobile app development cost in UK. If the team is in North America or Europe, it would charge more as compared to the team in Asia or Australia. The development charges are also determined by the expertise of the team. Experienced developers would generally charge more. 

[5] Integration with Third-Party Services

Third-party integrations, such as APIs of payment gateways and social media platforms, increase the overall features and functionalities of the mobile app, but they require additional licensing and subscription fees, hence increasing the development costs. 

[6] Maintenance and Updates

Every app requires regular maintenance to ensure it works fine without any bugs and errors for a long time. The app would require updates for new features and functionalities to keep up with the latest market trends. Maintenance and regular updates increase the overall development costs but are necessary. 

[7] Security Features

Protecting the user data and overall app is of the highest priority. Features such ass end-to-end encryption, advanced security measures, regulations such as GDPR, etc add up to the costs. 

[8] Marketing and Launch Costs

Deploying and launching the app after development does not end of the line. Extensive marketing campaigns and advertisements on social media and search engines are launched to promote the app to reach a wider audience.
