How much does an MVP cost in the UK?

The short answer

There's no single price for an MVP, because an MVP is defined by the question it answers, not by a list of features. What we can tell you is what drives the number. At Vebryx, a Validation MVP starts from under £6,000 at a fixed price and takes 2–4 weeks. A fuller custom platform usually takes around eight weeks and is quoted on its scope. For a figure for your own idea, our MVP cost calculator gives an instant estimate in pounds.

The rest of this guide explains where the money goes, which choices move the price most, and the costs founders tend to forget.

What an MVP budget actually pays for

An MVP isn't just code. A good one pays for the work that stops you building the wrong thing:

• Validation: research and tests with real people, such as interviews, a landing page or a waitlist, to check the problem is worth solving.
• Scope and roadmap: cutting the idea down to the smallest version that proves your riskiest assumption, with a clear plan and price.
• Design and prototype: clickable screens you can put in front of users before development starts.
• Build: front end, back end and integrations, delivered in short sprints you can see.
• Testing and launch: quality checks across devices, then a release to your first users.
• Measurement: analytics set up from day one, so what happens next is based on evidence rather than opinion.

If a quote only covers the build, ask who does the rest. Skipping validation is the most expensive saving you can make, because it's how founders end up paying for features nobody uses.

The four choices that move the price most

Our calculator uses the same pricing model we use when we scope projects. Four choices do most of the work.

1. Platform

A web app is the cheapest place to start: it runs in any browser and there's no app store review. In our model, the same features built as a mobile app for iOS and Android cost about 2.4 times the web version, and web plus mobile together about 3.4 times. Cross-platform frameworks such as React Native and Flutter keep mobile costs down by sharing one codebase across both stores. Our page on web and mobile app development explains the trade-offs.

2. Features

Every feature adds design, build and testing time, but not equally. Features that involve real-time data, third-party services or a lot of screens cost the most. In our pricing, the heaviest are:

• AI features: model integration, prompt design, testing against real examples and cost monitoring.
• Real-time chat: messages that sync instantly between users, with notifications and moderation.
• Dashboards and reports: data pulled together, calculated and shown clearly.
• Admin panel: the tools your team needs to run the product behind the scenes.
• Booking and scheduling: availability, time zones, reminders and cancellations.

Lighter features include onboarding, notifications and reviews. The fastest way to reduce cost is to ask of every feature: would a first user miss it if it wasn't there?

3. Pace

Speed costs money, because it means more people working in parallel. In our model, a fast-track build costs about 1.5 times the same scope on a relaxed timeline. If you have a hard deadline, such as an investor meeting or a launch event, it can be worth it. If you don't, a steadier pace buys the same product for less.

4. MVP or full product

A full product with the same features costs about 1.5 times an MVP in our model, because it needs edge cases handled, more polish, deeper testing and foundations for scale. Extending a product you already have usually costs less than starting fresh.

Costs founders forget

The build is the biggest cost, but not the only one. Budget for:

• Hosting and services: servers, databases, email sending, maps and file storage. Small at first, growing with your users.
• App store accounts: if you're publishing a mobile app, Apple charges an annual developer membership and Google Play a one-off registration fee.
• Usage-based AI costs: most AI providers charge per use, so costs grow as the product succeeds. Estimate them during the prototype.
• Maintenance: security updates, operating system changes and bug fixes after launch.
• The next iteration: an MVP is the start of learning, not the end. Keep budget back for what users tell you.
• Your first users: a product nobody hears about teaches you nothing. Plan for launch marketing, even if it's small.

How to spend less without cutting corners

• Validate before you build: a waitlist or landing page test costs a fraction of a build. Our free idea stress test helps you find your weakest assumption first.
• Test one assumption at a time: build the smallest thing that proves or disproves it, then decide what comes next.
• Start on the web: unless your idea depends on the phone, such as the camera, location or notifications on the go, a web app gets you to real users faster.
• Consider no-code for validation: platforms like Bubble and Webflow can get a working product live in days. Our guide to no-code vs custom code covers when that's the right call.
• Agree a fixed scope: a fixed price for a fixed scope keeps both sides focused on what matters.

Fixed price or time and materials?

With time and materials, you pay for the hours worked. It's flexible, but the final cost is only known at the end. With a fixed price, the scope and cost are agreed up front, and changes are discussed and priced before they're made.

For an MVP we recommend a fixed price. The scope is small and deliberately limited, so it can be defined clearly, and a fixed budget stops the project drifting into a full product before you've learned anything. Our Validation MVPs are fixed scope and fixed price.

Why prices vary so much between UK agencies

Two agencies can quote very different prices for what sounds like the same MVP. The usual reasons are location and team model, with London day rates typically higher than elsewhere; how much validation and design is included; and whether the quote covers testing, launch and support or only the build.

Vebryx is headquartered in Glasgow, with a production studio in Pakistan. That lets us keep prices below many London agencies while following the same process: weekly demos, clear milestones and a product whose code, designs and accounts you own.

Questions to ask before you sign

• What exactly is in scope, and what isn't?
• Is validation or user testing included, or only the build?
• Who owns the code, designs and accounts at the end?
• How are changes priced if we learn something mid-project?
• Who tests the product, and on which devices?
• What happens after launch, and what does support cost?
• Can I see a product you've built for a similar problem? Ours are in our case studies.
