MVP Development Costs in the UK (2025)

The cost of MVP development varies depending on the complexity of the project. For entry or lightweight MVPs, the typical cost ranges from £15,000 to £30,000. These MVPs usually feature basic functionalities, are built for a single platform (web or mobile), and have limited integrations.

For standard MVPs, costs generally fall between £30,000 and £70,000. These MVPs tend to have more complex features, support multiple platforms, and integrate third-party services, offering a more robust solution for testing product-market fit.

When it comes to complex or enterprise-level MVPs, costs can range from £70,000 to £200,000+. These MVPs typically include advanced features such as real-time data processing, machine learning, support for multiple platforms, and high security, making them ideal for regulated industries like finance or healthcare.

What Drives MVP Costs?

Several factors influence the cost of MVP development:

• Scope/Feature Count: More features like user authentication, payment systems, and data storage increase costs.
• Platforms: Developing for multiple platforms (iOS, Android, web) adds complexity and cost.
• Integrations: APIs, third-party services, and data integrations raise the price.
• Data/AI: Projects involving advanced data processing or machine learning require additional expertise and resources.
• Compliance & Security: For industries with strict regulations, such as healthcare or finance, additional security measures and certifications are necessary.
• Design Depth: Custom UI/UX design adds to costs compared to pre-built templates.
• Seniority Mix: Senior developers or specialists (like data engineers or AI experts) typically come at a higher price.

Pricing Models

• Fixed-Scope Discovery → Fixed/Target-Cost Build: This is a common approach where the MVP’s features are defined during the discovery phase and built within a set budget.
• Sprint-Based (Agile): Ideal for projects that need flexibility and ongoing iterations.
• Hybrid: A combination of fixed-scope discovery with agile sprints for future feature development.

How to Control Your Budget

You can control your MVP budget by focusing on ruthless scoping, prioritizing must-have features, and launching on a single platform first before expanding to others. Reusing design systems, using no-code or low-code solutions for simpler MVPs, and focusing on analytics before "nice-to-haves" can also help keep costs down.

Timelines & Delivery Patterns

The typical timeline for developing an MVP ranges from 4 to 12 weeks, depending on the complexity and features. Timelines can be shortened or extended depending on factors such as team size, feature complexity, platform support, and integration depth.

The milestones generally include:

• Discovery (1-2 weeks): Defining the MVP scope and features.
• Prototype (2-3 weeks): Creating a clickable prototype to validate concepts.
• MVP Build (4-6 weeks): Developing the first usable version of the MVP.
• Beta (2-4 weeks): Releasing to a select group of users for feedback.
• Iterate & Refine (ongoing after launch): Enhancing the product based on user feedback.

According to Adriana Gruschow, building an MVP is not about speed alone; it’s about structured experimentation. While typical timelines range from 4–12 weeks to the first usable release, allowing time for early testing and iteration ensures the MVP truly meets market needs.

How to Choose the Right UK MVP Partner (Checklist)

When choosing an MVP development partner in the UK, consider the following:

• UK presence/time-zone fit: Ensure the partner’s location aligns with your team’s working hours.
• Sector experience & case studies: Look for partners with relevant industry experience.
• Architecture & code quality standards: Make sure they follow best practices for scalable and maintainable code.
• Security/compliance: Ensure they meet your security and compliance requirements.
• Analytics/experiment setup: Make sure they can implement tracking and testing for future iterations.
• Handover/scale plan: Ensure there is a clear plan for handover and scaling the MVP post-launch.
• Support SLAs: Ensure they offer adequate support and maintenance post-launch.

Red Flags to Watch Out For

• Vague scope with no clear definition of features.
• Lack of a release plan or commitment to post-launch iterations.
• No commitment to QA automation or proper testing.
• No guarantee of post-launch iteration or support.
