If you're a founder trying to work out your budget before speaking to developers, here's the short answer: building an MVP in the UK typically costs between £15,000 and £80,000, depending on complexity, platform, and who builds it. Some products can be validated for under £10,000. Others genuinely need £100,000 before they're investable.
The wide range isn't vague — it reflects real differences in scope, team setup, and product type. This guide breaks it down clearly so you can make an informed decision before committing a penny.
Key Takeaways
- Most UK MVPs cost between £15,000 and £80,000 to build
- Simple web app MVPs can be scoped from £10,000 to £25,000
- Mobile app MVPs typically start from £25,000
- SaaS and marketplace MVPs usually range from £30,000 to £80,000+
- Freelancers are cheaper upfront but carry more risk; agencies cost more but offer structure
- Timeline is typically 8 to 20 weeks depending on scope
- The biggest cost driver is feature scope, not technology choice
- Cutting scope is always cheaper than cutting quality
What Is an MVP, Actually?
An MVP — minimum viable product — is the smallest version of your product that lets you test your core assumption with real users. It's not a rough prototype. It's not a demo. It's a functional product that does one thing well enough for someone to pay for or seriously engage with.
The confusion around MVP costs often starts here. Founders sometimes scope an MVP that's actually a full product. Others build something so stripped back it can't be tested meaningfully. Getting this balance right has a direct impact on cost.
MVP vs Prototype
A prototype is usually a visual mockup or clickable demo — built to communicate an idea, not to function. Development cost is minimal, often £2,000 to £8,000 for a solid UI/UX design and prototype.
An MVP is engineered. It has real logic, real data, real user flows. That's where the cost sits.
What Affects MVP Development Cost?
Before quoting a number, any decent agency or developer will want to understand your product properly. These are the main variables that move the price.
Feature Scope
This is the biggest cost driver, by far. Every feature you add requires design time, development time, testing time, and integration work. A login system, payment processing, a dashboard, notifications, an admin panel — these all add up quickly.
Most founders scope too broadly on the first pass. A good development partner will challenge your feature list and help you identify what's genuinely required to test your hypothesis versus what can come later.
Platform Choice
Building for web only is cheaper than building for web and mobile. A web app MVP is typically the most cost-effective starting point. A native mobile app (iOS and Android) roughly doubles the build cost compared to a responsive web app.
If your core users are mobile-first and the product genuinely requires native device features, mobile is justified. If not, start with web.
Design Requirements
An MVP doesn't need to be beautiful, but it does need to be usable. Poor UX kills conversion, even at the MVP stage. Most MVP budgets should include at least 2 to 4 weeks of proper UI/UX design work. Skipping this usually costs more in the long run when assumptions get rebuilt.
Integrations
Payment gateways, CRM systems, third-party APIs, email providers, mapping services, video calls — every integration adds complexity and time. Even simple ones like Stripe require careful implementation to handle edge cases correctly.
Team Setup
Whether you use a UK agency, an offshore development team, or freelancers significantly changes cost and risk profile. More on this below.
MVP Cost by Product Type
| Product Type | Estimated Cost | Typical Timeline |
|---|---|---|
| Simple web app MVP | £10,000 – £25,000 | 6 – 10 weeks |
| SaaS MVP (web-based) | £25,000 – £60,000 | 10 – 16 weeks |
| Mobile app MVP (iOS or Android) | £25,000 – £55,000 | 10 – 18 weeks |
| Mobile app MVP (iOS + Android) | £40,000 – £80,000 | 14 – 22 weeks |
| Marketplace MVP | £35,000 – £80,000 | 12 – 20 weeks |
| Ecommerce MVP | £15,000 – £40,000 | 8 – 14 weeks |
| Healthtech / regulated MVP | £50,000 – £150,000+ | 16 – 30 weeks |
These ranges assume a UK-based or near-shore team. Offshore development can reduce costs by 40 to 60%, but introduces its own tradeoffs around communication, quality control, and timelines.
Freelancer vs Agency for MVP Development
This is one of the most common questions founders ask, and the honest answer is: it depends on your risk tolerance and how much hands-on involvement you can provide.
| Freelancer | MVP Development Agency | |
|---|---|---|
| Typical day rate | £300 – £600/day | £500 – £900/day (blended) |
| Project management | You manage it | Included |
| Design included | Rarely | Usually |
| Continuity | Risk of drop-off | Team continuity |
| Best for | Simple builds, tight budgets | Complex products, speed to market |
| Risk level | Higher | Lower |
| Accountability | Individual | Company-level |
Freelancers work well if you're technical enough to manage the project, have a very simple scope, or are working with someone you've already vetted. For most non-technical founders building their first product, an MVP development agency provides more structure, accountability, and a cleaner path to a working product.
The cost difference is real, but so is the difference in risk.
Hidden Costs Founders Often Overlook
The quoted build cost is rarely the total cost. Here's what typically gets missed:
Infrastructure and hosting. Cloud hosting on AWS, GCP, or similar starts cheap but scales with usage. Budget at least £100 to £500 per month for a live MVP.
Third-party services. Email providers, analytics tools, error tracking, payment processing fees — these add up. Stripe charges 1.4% + 20p per transaction on European cards.
Post-launch fixes. No MVP launches perfectly. Bug fixes, performance issues, and UX tweaks after go-live are inevitable. Build a contingency of 15 to 20% into your budget.
App store fees. If you're launching a mobile app, Apple charges £99 per year for the App Store developer programme. Google charges a one-time £20 fee.
Ongoing maintenance. Security patches, dependency updates, and platform changes need attention every few months. This typically costs £500 to £2,000 per month depending on complexity.
Legal and compliance. GDPR compliance, privacy policies, terms of service, and cookie consent aren't optional. Factor in at least £500 to £2,000 for proper legal documentation.
How Long Does It Take to Build an MVP?
Most MVPs take between 8 and 20 weeks from kick-off to launch. The timeline depends on:
- How clear and stable the scope is at the start
- How quickly the client provides feedback and approvals
- Whether design is done in parallel or sequentially
- The size and experience of the team
Beware of timelines under 6 weeks unless the scope is very narrow. Compressed timelines usually mean cutting corners on testing, security, or UX — which tends to create expensive problems post-launch.
What Features Should an MVP Include?
This is where most founders need the most honest guidance. A well-scoped MVP should include:
- Core user journey only. The one flow that delivers your core value proposition. Nothing else.
- Authentication. User sign-up, login, and basic account management.
- The primary feature. Whatever makes your product worth testing.
- Basic admin capability. Enough for you to manage users and data without direct database access.
- Error handling and basic security. Not optional, even at MVP stage.
Everything else — notifications, referral systems, social sharing, advanced analytics, multiple user roles, complex dashboards — is post-MVP unless it's genuinely core to the testable hypothesis.
How to Reduce Development Costs
There are smart ways to reduce cost without compromising the validity of what you're testing.
Narrow the scope aggressively. Be ruthless about what goes in V1. Every feature you defer saves real money.
Use proven third-party tools. Don't build custom auth, payment processing, or email delivery from scratch. Tools like Auth0, Stripe, and SendGrid exist for a reason.
Start with web only. Unless your product fundamentally requires native mobile, a responsive web app is significantly cheaper and faster to build.
Invest in design upfront. A clear, detailed design before development starts reduces back-and-forth and scope creep significantly. It's cheaper to change a design file than to rebuild a feature.
Choose the right stack. A good web development team will choose a stack appropriate to your product, not the most technically impressive one.
Validate assumptions before building. Interviews, landing pages, and paper prototypes can answer big questions for very little money. The best way to reduce MVP cost is to validate your riskiest assumption before writing a line of code.
Do You Actually Need an MVP?
Not always. It's worth asking whether a properly designed landing page with a waitlist or a lightweight prototype test could answer your core question more cheaply. For some businesses, a concierge MVP — where you deliver the service manually before automating it — is smarter than building software at all.
If you've already validated demand and you need working software to acquire your first customers or raise pre-seed funding, then yes — build the MVP. If you're still testing whether the problem is real, spend less first.
Frequently Asked Questions
How much should a startup spend on an MVP?
Most early-stage startups spend between £15,000 and £60,000 on an MVP. How much you should spend depends on your runway, your funding situation, and how much validation you've already done. Don't build more than you need to test your core hypothesis.
Can you build a Minimum Viable Product for under £10,000?
Yes, but only for very simple products — typically a landing page with basic functionality, a lightweight web tool, or a product with a very narrow single feature. For anything more complex, sub-£10,000 budgets usually result in something that isn't fit for real user testing.
Is it cheaper to build an MVP offshore?
Offshore development (Eastern Europe, India, South-East Asia) can reduce costs by 40 to 60%. The tradeoff is communication overhead, time zone friction, and variable quality. For a first-time founder without technical experience, managing an offshore team is genuinely difficult. Near-shore teams in Poland, Romania, or Portugal offer a middle ground.
How do I know if an agency is quoting fairly?
Get at least three quotes. Ask each agency to walk you through their assumptions and what's included. A fair quote will break down design, development, project management, and testing separately. Be cautious of very low quotes that bundle everything together without explanation.
What's the difference between an MVP and a prototype?
A prototype is a visual mockup or interactive demo used to test a concept. It isn't functional software. An MVP is working software that real users can actually use. Prototypes cost far less but can't replace the learning you get from a real product in people's hands.
How long does development typically take?
Most MVPs take 8 to 20 weeks. A simple web app with a clear scope can be built in 6 to 10 weeks. A complex SaaS platform or marketplace will typically take 14 to 22 weeks. Rushed timelines are usually false economy.
Final Thoughts
Understanding how much it costs to build an MVP isn't just about finding the cheapest quote. It's about understanding what you're actually building, why you're building it, and how to get the most useful signal from your investment.
The founders who get the most out of their MVP budgets are the ones who scope ruthlessly, choose partners carefully, and treat the MVP as a learning tool rather than a finished product. A £30,000 MVP that teaches you something real is worth far more than a £60,000 MVP that confirms what you already assumed.
