How much does an app cost in the UK in 2026?

The honest answer is "anywhere from £499 to £500,000". The interesting answer is why the gap is so wide and how to land at the right end of it.

The market

London agency

£40k–£250k

Same Kotlin or Swift you would get anywhere, with a Soho lease baked in.

Offshore body shop

£8k–£25k

Cheaper, but timezone friction and patchy quality control.

Where we sit: a £499 PWA Android starter offer (Play Store listing add-on £100), and a fixed quote inside 24 hours for everything bigger. £0 upfront until you approve the result.

Why the gap is so big

An app build is mostly time. Around 30% of that time used to go on plumbing: setting up auth, wiring up the database, repetitive UI screens, integrating Stripe, writing tests. Modern AI coding tools (Claude, Cursor, Copilot) compress that 30% into a fraction. The remaining 70%, the bit that needs human judgement, still takes the same time. The total comes down by 60 to 80%.

Agencies have not passed those savings on. They still bill at 2018 rates because the market lets them. We pass them on.

The build is one cost. After launch you also need:

An MVP that used to cost £30k can now ship for £3k. The trick is finding a builder who is using modern tools and not pretending they are not.
