What you should know
What Affects the Cost to Build an App in the UK?
Every project is unique. Here are the key factors that determine your final development cost.
App type and platform
iOS, Android, or cross-platform (Flutter/React Native) apps each have different cost profiles. A cross-platform app typically costs 30–40% less than building native iOS and Android separately.
Features and complexity
A simple MVP with 3–5 screens costs far less than a full-featured marketplace or fintech platform. Every feature adds development time.
Design requirements
Custom UI/UX design adds to the budget but significantly improves user retention. Basic apps use templates; complex products need bespoke design.
Team location
UK-based agencies typically charge £80–£150/hr. Offshore teams with UK timezone alignment (like Tecaudex) deliver the same quality at significantly lower rates.
Ongoing maintenance
Factor in 15–20% of your build cost annually for updates, hosting, and bug fixes.
