Direct Answer
Java Developer salaries range from £28,000 to £780–£1,120/day. Java with Spring Boot 3 + Java 21 (virtual threads — Project Loom, replacing reactive programming for many high-concurrency use cases) commands premium. Java with FCA-regulated financial systems (payments engines, trade finance, core banking — complex Java enterprise) commands significant premium. Java with AWS (Spring Boot deployed to ECS Fargate via AWS CDK — not traditional Java application servers) commands growing premium. Java with Kotlin (Kotlin is JVM-compatible — senior Java engineers transitioning to Kotlin for Spring Boot projects) commands premium.
Market Outlook
Java Developers write enterprise applications using the Java Virtual Machine (JVM). Java remains one of the UK's most in-demand languages in 2026 — particularly in banking, insurance, and large enterprise software. The Spring Boot ecosystem (Spring MVC, Spring Security, Spring Data JPA) is the UK Java standard for new projects.
