App Development Cost UK: What You’ll Really Pay to Build an App

If you’re researching app development cost UK figures, you’ll find quotes ranging from a few thousand pounds to six figures. That isn’t agencies being vague; it reflects how differently apps can be built. As a rough guide, a simple app costs £10,000 to £30,000, a mid-range app £30,000 to £80,000, and a complex platform £80,000 to £150,000 or more.

We’ve designed and built apps since 2021, including the AFC Telford United app that won the Innovation Award at the Football Business Awards, and our own StandBased club app platform. Here’s what really shapes app development cost UK quotes, so you can budget with confidence.

Typical app development cost UK price ranges

• Simple app (£10,000–£30,000): a handful of screens, basic content, a contact or booking form, and a light back end.
• Mid-range app (£30,000–£80,000): user accounts, payments, push notifications, integrations with your existing systems and an admin panel.
• Complex app (£80,000–£150,000+): real-time features, marketplaces, custom dashboards, multiple user types and heavy integration work.

These ranges are typical of the market rather than fixed prices. Every app development cost UK estimate should be based on a written scope, so you know exactly what’s included.

What drives the cost of an app?

Features and complexity

Every feature needs design, development and testing. Logins, payments, live data and chat add up quickly. The fastest way to control app development cost UK budgets is to launch with the features that matter most, then add more later.

iOS, Android or both

Building natively for each platform costs more than using a cross-platform framework such as Flutter or React Native, which lets one codebase run on iPhone and Android. For most businesses, cross-platform is the sensible choice. Flutter, which we use for many of our apps, also makes future updates quicker, because each change only needs making once.

Design

A bespoke, branded interface costs more than a template, but it’s what makes people keep your app on their home screen. Expect design to account for roughly 10–20% of the total budget, covering wireframes, visual design, an interactive prototype and accessibility checks, so the app works for everyone, including people who use larger text or screen readers.

Back end and integrations

Apps usually talk to a server, a database and other systems such as ticketing, stock or payment providers. Integrations are often the hidden part of app development cost UK quotes, so ask about them early.

Ongoing costs after launch

Building the app is only the start. Budget for:

• Hosting and services: typically £50–£500 a month (£600–£6,000 a year), depending on users and data.
• Maintenance and updates: a common rule of thumb is 15–20% of the build cost each year. For a £40,000 app, that’s roughly £500–£670 a month (£6,000–£8,000 a year).
• Store fees: Apple’s developer programme costs £79 a year, and Google Play charges a one-off US$25 registration fee.

Including these figures gives you a true picture of the app development cost UK businesses face over the app’s lifetime, not just on launch day.

How to reduce app development cost UK budgets without cutting corners

• Start with a minimum viable product (MVP) and grow from real user feedback.
• Use cross-platform development to share one codebase.
• Reuse proven components rather than reinventing logins or payments.
• Write a clear brief, because changing direction mid-build is expensive.
• Consider an existing platform. Football clubs on StandBased get a professional app for a monthly fee instead of a one-off build.

Is building an app worth it?

Before you think about app development cost UK figures, ask whether customers will return often enough to justify an app: ordering, booking, collecting loyalty points or following live updates. The AFC Telford United app, for example, has passed 3,000 downloads and generated income the club needed after the pandemic. If your customers only visit once a year, a fast mobile website might serve you better.

Frequently asked questions

What is the average app development cost UK companies pay?

Most small and medium-sized businesses spend between £20,000 and £80,000 on their first app, depending on features and integrations.

How long does it take to build an app?

A simple app can take 8–12 weeks. Mid-range and complex apps usually take four to nine months from discovery to launch.

Is it cheaper to hire a freelancer than an agency?

A freelancer can cost less upfront, but an agency brings design, development, testing and ongoing support under one roof, which reduces risk if something goes wrong after launch.
