How much does mobile app development cost in London?

Mobile app development in London starts at GBP 1,500, and the final cost depends on scope. Fintech apps sit considerably higher because SCA, Open Banking consent handling and security review are substantial work. We price three ways: fixed cost once scope is agreed, hourly from GBP 15 for standard work, or a dedicated developer from GBP 2,000 per month with a discount on longer retainers. The quote is your total unless the scope changes.

Can you build Open Banking apps?

Yes. The engineering reality of Open Banking is consent management rather than the API calls themselves — handling 90-day reauthorisation, revocation and partial consent cleanly. That is where most implementations get thin, so we scope it explicitly.

Do your apps meet accessibility requirements?

We build to WCAG 2.2 AA and test against it. If you are selling into public sector or large enterprise, accessibility is usually contractual, and discovering a failure during procurement is the worst possible time. Building to standard from the start costs a fraction of retrofitting.

How long does it take to build a mobile app in London?

8-14 weeks from kickoff to store submission for most projects. Regulated fintech apps run longer, mainly because security review and compliance sign-off sit on the critical path rather than because the build itself is slower.

London, United Kingdom

Building mobile apps for London businesses

A large share of London app work touches financial services, and that changes the engineering brief. Strong Customer Authentication under PSD2 dictates how your login and payment confirmation flows can be designed. Open Banking integration means working with consent lifecycles and 90-day reauthorisation rather than a simple API key. These are not features you add in a later sprint; they shape the app's core flows.

Accessibility is the other London-specific pressure. Public sector contracts and increasingly large enterprise procurement carry WCAG requirements, and apps that fail an accessibility audit get rejected at exactly the point they were meant to go live. Building to standard costs comparatively little; retrofitting screen reader support and focus management into a shipped app is expensive and often means redesign.

We treat both as scope from the first sprint.

From: GBP 1,500

Timeline: 8-14 weeks

Platforms: iOS, Android, cross-platform

Accessibility: WCAG 2.2 AA

Compliance: UK GDPR, PSD2 SCA

How pricing works

Mobile App Development from £1,500

That is a genuine starting point, not a headline figure — the final cost depends on scope. Whichever model suits you, we agree it in writing before any work begins.

Fixed cost

Quoted on scope

per project

Agree the scope, get a fixed total. It does not move unless the scope does.

Hourly

From £15

per hour

For change requests, ad-hoc work, or when the scope is still forming. Specialist skills are quoted separately.

Dedicated developer

From £2,000

per month

A developer working only on your product. No recruitment, no notice period, and longer retainers are discounted.

A fixed price needs a defined scope, so we scope first and quote second. If you are not sure what you need yet, hourly or a dedicated developer is usually the better starting point.

Built for London

What building for the London market actually involves

The requirements below are specific to this market. They are the things that get discovered late and expensively when a project is scoped against a generic template.

Open Banking integration

Account information and payment initiation flows built around consent lifecycles, including the reauthorisation and revocation paths that get skipped in demos and matter in production.

Strong Customer Authentication

PSD2-compliant authentication and payment confirmation, with biometric flows designed to satisfy SCA rather than sit alongside it.

Accessibility to WCAG 2.2 AA

Screen reader support, focus order, contrast and touch target sizing built in and tested — because failing an accessibility audit at launch is the expensive way to discover this.

UK GDPR data handling

Explicit decisions on data residency, retention and consent, implemented in the app and backend rather than described in a policy document.
