How Much Does Mobile App Development Cost? (United Kingdom)

UK SMEs often expect a written statement of work and fixed-fee phases rather than open-ended retainers. Duyuz EUR floors (web from €590, SEO Growth €399/mo) map cleanly to that habit when scope is locked first. Duyuz mobile app work is discovery-led. Many MVPs land in a ballpark from about €8,000 depending on platforms, features and integrations — with written scope after we know the job-to-be-done. Native store apps, complex backends or realtime features cost more than a focused PWA.

Direct answer

What should you budget?

Treat ~€8,000 as a published starting conversation for scoped MVP work — not a blind fixed bid. Platform choice (PWA vs store apps), features and APIs determine the real number.

Ranges

Basic, intermediate and advanced scopes

Basic / PWA-first

Often below full native MVP

When mobile web or PWA meets the need — scoped after discovery.

Intermediate MVP

From ~€8,000

Core flows, one primary platform path, essential integrations.

Advanced product

Custom

Multi-platform native, complex backend, realtime, offline sync, or heavy compliance.

Typical project scope

Discovery, UX for core flows, build on an agreed stack, analytics events, and launch readiness (store consulting when applicable).

How quotes work

Describe users, must-have flows and deadline. We spike risky integrations early and quote a bounded MVP — not an infinite v1.

Service businesses lean hard on Trustpilot / Google reviews before booking discovery calls✓
London agency day-rates set a high mental anchor — published EUR floors feel transparent by contrast✓

FAQ

How much does it cost to build an app in 2026?

It varies widely. Duyuz uses discovery to bound MVP cost; many focused MVPs start in conversation around €8,000+, while complex products are custom.

Do I need a native app?

Not always. We recommend native when store distribution or device capabilities truly matter.

How long is an MVP?

Often roughly 8–16+ weeks after discovery, written in the proposal.

Fixed price or time and materials?

We prefer fixed scope for MVP boundaries; open-ended product discovery is quoted differently.

Can UK companies pay in GBP?

Quotes are framed from published EUR floors. We can show indicative GBP and confirm payment currency in writing before work starts.

Do you understand UK VAT?

Tax treatment is stated on the quote. Cross-border VAT depends on your entity — We work remotely with businesses across Europe, the UK and the US.
