Java Development in the UK

For most business-to-business services supplied from outside the UK, the reverse charge applies: you account for the VAT in your own return rather than paying it to us, and it is typically neutral if you are fully recoverable. Our invoices state the position clearly so your accountant is not guessing. If your situation is unusual, for example partial exemption, we would rather your accountant confirms the treatment before we invoice than after.

We build to it rather than claiming a certificate. In practice that means data minimisation designed in rather than bolted on, a documented lawful basis for each processing activity, retention periods that actually delete, subject access and erasure handled as features rather than manual database work, and hosting in a region you approve. Where we process personal data on your behalf we sign a processor agreement setting out exactly that.

Yes, and it is scoped from the start because retrofitting accessibility is considerably more expensive than building it in. We work to WCAG 2.2 AA, test with a screen reader rather than relying on an automated scan, and produce the accessibility statement the regulations require. Automated tools catch perhaps a third of real issues, which is why the manual pass is not optional.

We are happy to contract under English law with the courts of England and Wales, and most UK clients prefer that. IR35 does not apply to us: it governs individuals working through an intermediary, and you are engaging a company for a defined deliverable rather than a person for their time. Your accountant will want to see that the contract reflects that, and ours does.

We are straight about this: Java is a service line we take on, not the stack most of our shipped work runs on. Since 2021 we have delivered 70+ projects in total, with the bulk in Node.js, TypeScript, and PHP rather than Java. What we bring to a Java build is senior engineering discipline that transfers directly, REST API design, testing, CI, and the PostgreSQL and AWS work we do every week, plus a promise not to bill you for learning basics on the job. If your project needs deep JVM specialists we are not, we will tell you.

Spring Boot for the application, Spring MVC for REST, Spring Data JPA with Hibernate over PostgreSQL, and Spring Security with JWT or OAuth2 for auth. We build with Maven or Gradle, test with JUnit 5, Mockito, and Testcontainers, document APIs with OpenAPI, and deploy Docker containers to AWS with CI running on every push. We target current LTS Java, 17 or 21, and can work in older versions when an existing codebase requires it.

It depends on your situation, and we will give you an honest read rather than push the one you searched for. Java is the stronger pick when you already run on the JVM, are in an enterprise setting that standardizes on it, or are building a large, long-lived backend that many engineers will share. Node.js with TypeScript, which is where our deepest experience sits, usually gets a smaller product or MVP live faster and cheaper. Tell us the project and we will tell you which one we would actually choose.

Yes. That is most of the Java work we are asked for: Spring Boot REST APIs, documented with OpenAPI and secured properly, integrated with payment gateways, ERP or CRM systems, message queues like Kafka and RabbitMQ, and third-party REST or SOAP endpoints. We build in the retries, timeouts, and error handling that integrations need to survive real traffic, not just the happy path in a demo.

Yes, carefully. We migrate ageing Java EE, Struts, or old-Spring monoliths onto current Spring Boot and a supported LTS Java, one tested slice at a time, so the running system stays up while it moves. Before we pile features onto an inherited codebase we are honest about its state: if it needs a test harness or a cleanup pass first, we will say so rather than build new code on a shaky base.
