What to plan for when building an app in South East England

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
• Public sector bodies must meet the accessibility regulations (WCAG-based), and the Equality Act 2010 applies to everyone
• Enterprise buyers require integration with existing platforms, single sign-on and security questionnaires
• Financial services clients fall under FCA rules
