Mobile App Developers in Greater London

App development across Greater London

the UK's largest economy and financial centre. We help Greater London companies turn ideas into iOS, Android and cross-platform apps, from first-time founders to established teams replacing ageing software. Every project comes with a fixed-scope quote, senior engineers and real support after launch.

The Greater London economy and where apps fit

Greater London is the UK's largest economy and a global financial centre, with banking, insurance and asset management in the City and Canary Wharf, one of Europe's largest fintech communities, media and creative industries, professional services, life sciences, universities and the headquarters of many public bodies.

Dominant sectors

• Banking, insurance and asset management
• Fintech and payments
• Media, advertising and creative industries
• Professional services and law
• Life sciences and health
• Public bodies and universities

Universities and technology community

Imperial College, UCL, King's College and the London School of Economics feed a technology community that grew up around Shoreditch and now spans the capital, and London remains the UK's main centre for venture-backed startups.

What to plan for when building an app in Greater London

These are the region-specific points we raise in discovery. They are practical notes, not legal advice; your counsel confirms what applies to you.

• UK GDPR and the Data Protection Act 2018 govern personal data, with PECR covering marketing messages and cookies. The Data (Use and Access) Act 2025 amends these rules in stages between 2025 and 2026, so confirm current requirements with your adviser
• Financial apps fall under FCA rules including the Consumer Duty, so disclosures, journeys and complaints handling must be designed in
• Services likely to be used by children must follow the ICO Age Appropriate Design Code, and user-to-user features bring Online Safety Act duties
• Multilingual audiences and high design expectations from global brands
