App Development Cost in the UK in 2026: Prices, Rates and Agency Minimums

Building an app with a UK agency in 2026 usually costs $20,000 to $78,000 (about £15,000 to £60,000) for a simple app or MVP, and $65,000 to $195,000 (£50,000 to £150,000) for a mid-size app. London agencies sit at the top of those ranges. Complex apps run from $130,000 (£100,000) to well past $650,000 (£500,000).

Those are the headline numbers, and on their own they won't help you much. You need to know why two UK quotes for the same app can be £40,000 apart. We'll walk through where the numbers come from and how to get a solid first version without a London-agency budget.

We quote in US dollars so prices are easy to compare across markets. Pound figures are converted at about 1.30 dollars to the pound and rounded.

App development cost in the UK by app size

Regulated builds cost more again. A lot more. Fintech and health apps in the UK often start around $325,000 (£250,000) once compliance, security reviews and audit trails are in scope.

UK app developer rates: London vs the rest of the UK

Most of the gap between two quotes comes from the day rate behind them. It's the first thing we'd ask about.

An agency quote also covers project management, design and testing. A freelancer's rate usually doesn't. So compare like with like before you compare prices.

The agency minimum problem

Many established UK agencies won't start a project below a minimum budget. On Clutch, well-known UK studios list minimums from about $39,000 (£30,000) up to $65,000 (£50,000) or more.

That's fair for a funded scale-up. If you're building a first app or an MVP, though, it rules out a lot of the agencies with the strongest portfolios. You're left with three real options: a freelancer, a smaller regional studio, or an international team that works to UK standards at a lower rate.

What drives the price of a UK app build

• Scope. Every feature adds design, build and testing time. A clear feature list is the best predictor of cost.
• Platforms. One app for iOS and Android built with Flutter typically costs 25 to 45 percent less than two separate native apps.
• Backend. User accounts, data storage, admin tools and integrations with your CRM or accounting software.
• Design. Custom animation and illustration cost far more than a clean design built on standard components.
• Compliance. UK GDPR applies to any app that handles personal data. Health and finance apps carry extra rules on top.

Costs after launch

Launch isn't the end of the spend. Plan for maintenance at 15 to 20 percent of the build cost each year, because iOS and Android change every year and the libraries an app relies on keep moving underneath it. Add Apple's $99 yearly developer fee, Google Play's one-off $25 fee, and hosting that grows with your users. Keep some budget back for version two. Real users always change the plan, and that's a good thing.

How to brief an agency and get comparable quotes

1. Write a one-page scope: who the app is for, the screens, and the features that matter most.
2. Mark which features are must-haves for launch and which can wait.
3. Ask every agency what the quote includes: design, testing, App Store submission, and support after launch.
4. Ask who will actually build it, and where they're based.

A short, clear brief gets you quotes you can actually compare. In our experience it brings the numbers down, too.
