How much does it cost to build an MVP in the UK?

From £5,000. That gets you validation and design — the idea tested with real users, core flows de-risked and a build-ready quote — in 2–4 weeks; the full MVP build starts from £15,000. Both are scoped and agreed at a fixed price before we start — the number you sign off is the number you pay.

How long does an MVP take to build?

A prototype takes 2–4 weeks. A full MVP usually fits our typical project shape — around three months from design through development, testing and launch — with a clear timeline agreed upfront.

Will you try to upsell us mid-project?

No. The scope and price are fixed before anything starts, and payment is split into milestones, so you only pay as we deliver. If you want more later, that's a conversation you start — not pressure from us. And if you cancel within the first 21 days, you get your money back in full.

Who owns the MVP once it's built?

You do. Once the work is delivered and paid for, the code and the product are yours — you're not renting them from us or tied to us to keep building.

What should go in the MVP — and what shouldn't?

Less than you think. The version that tests your riskiest assumption with real users wins; everything else waits. We'll push back on features that don't earn their place, because a fatter MVP is slower to learn from and dearer to change.

MVP Development Company UK

Every step, with a team who's done it before

You've heard the horror stories — an MVP that balloons into a year-long build and a bill that never stops climbing. We work the other way: scope the one thing your idea has to prove, fix the price before we start, and cut anything that doesn't earn its place.

Find the risk

We work out the riskiest assumption your idea rests on and the smallest version that tests it with real users. Free, before you commit a penny — and we'll push back on features that don't earn their place.
Scope it

You see the exact feature list, the shape of the build and one fixed price — from £5,000 to validate and design the idea in 2–4 weeks, from £15,000 for the full production build. The number you sign off is the number you pay.
Build it

We design, build, test and launch in short stages, paid by milestone so you only pay as we deliver — a live product in around three months. Cancel in the first 21 days and you get your money back in full.
Grow it

After launch, support runs from £400 a month for fixes and improvements as real users arrive — or you take the code and build on with any team. It's yours on payment either way.

First versions that found users

The point of an MVP is what happens after launch. Becon's safety app passed 1,500 downloads and picked up national press within 3 months; a homeowner–contractor marketplace shipped as a lean bidding MVP; a treasure-hunt platform went live in UK cities from York to Edinburgh.

The tech

The stack we build MVPs on — platforms we've shipped client products with, plus the ones we work with when they fit. No CV padding.

React Native

Bonsai's wealth-planning app ships from one React Native codebase — one build serving iOS and Android is usually the right MVP economics.
Flutter

We work with Flutter where it fits a team or an existing codebase — the cross-platform decision matters more than the framework brand.
Django & Python

Most of our MVP backends are Django, the same stack behind Go Quest's platform — boring, proven and quick to build is exactly what an MVP needs.
Firebase

For lean first versions we've shipped on Firebase — auth, data and hosting handled, so the budget goes on the product instead of plumbing.
AWS & Google Cloud

MVPs launch on the same AWS and Google Cloud infrastructure our production apps run on — nothing to migrate off when it takes off.
Stripe

We've shipped subscription systems on Stripe, so an MVP can take money from day one — revenue is the best validation there is.
OpenAI

AI features in an MVP run on the OpenAI models we've shipped with in client products — scoped to the one capability the idea needs.
And much more

This is what comes up most often, not a limit. Bring us something that isn't on this list and we'll get up to speed on it — working with something new is the job, not an obstacle.

What our clients are saying

Real reviews from clients we have delivered for, on Clutch and elsewhere.

4.9 via Clutch

The enthusiasm, understanding of our mission, and passion from the first few minutes of the call were the deciding factors in choosing CodeLeap. Within 3 months of our app launching, we had over 1,500 downloads, appeared in leading publications from Forbes, The Metro, Marie Claire, Women's Fitness and many more, and started raising further investment.

Charlie CEO, Becon
They are incredibly diligent in the quality of work they produce, and go above and beyond when it comes to solving issues faced within the project, and to ensure we meet strict project deadlines. You never feel like you are one of many clients, and they ensure they are always there to help with any need you have, no matter how big or small.

Amelia Parmiter Marketing Manager, AWS - Marble
CodeLeap made me feel like my options were limitless in terms of what could be achieved, which was critical to me as we were creating something very unique. I'm glad I chose Codeleap over a large corporation as the personable approach resulted in a smooth and pleasant experience.

James CEO, Bearable
Working with CodeLeap was a very good experience from both a professional and personal point of view. These people know what they are doing and are both efficient and clever and made a good partner. I wouldn't hesitate to recommend CodeLeap.

John CEO, Neurometrics-Diab
CodeLeap adds so much value and goes above and beyond what I expected. CodeLeap's team is very flexible with all the different requests we've put in front of them. They've also been great with the whole business side of things, and being able to forecast for this industry is really helpful. Overall, I'm completely satisfied with their work — they've been incredibly helpful.

Johanne CEO, Cherry
Their flexibility and focus on quality were outstanding.

Mike Fenna CTO, Kite Insights
