How Much Does It Cost to Build an App in the UK?

"How much does an app cost?" is the most common question we're asked — and the honest answer is that it depends entirely on what the app needs to do. This guide explains the factors that drive the price so you can budget with confidence.

What drives the cost of an app

The biggest cost driver is scope: the number of features, how much custom logic sits behind them, and how many systems the app has to talk to. Other factors include:

• Whether you need a backend, admin dashboard and APIs as well as the app
• Design complexity and the level of polish required
• Integrations — payments, messaging, third-party or clinical systems
• Security and compliance requirements (these matter a lot in regulated sectors)
• Ongoing support, hosting and iteration after launch

Typical price ranges

As a rough guide, a focused MVP — a first version that proves the core idea — usually takes 6–10 weeks to build. A larger platform spanning a mobile app, backend and admin dashboard typically runs 3–6 months. Cost scales with that timeline and the size of the team involved. We give every client a tailored quote after a short discovery conversation rather than a one-size-fits-all number.

Fixed price vs time & materials

For well-defined projects we can work to a fixed price. For products that will evolve as you learn from users, a sprint-based approach is often better value — you stay in control of the budget and can re-prioritise as you go.

How to keep costs sensible

Start with a tightly scoped MVP, build cross-platform with Flutter so you're not paying for two separate codebases, and plan the backend properly up front so you're not rebuilding it later. Cutting corners on security or architecture nearly always costs more in the long run.
