Java Developers in the UK

We are an Indian engineering team working with businesses in the UK. Written scope before any code, and a fixed quote in GBP.

Working hours

Our day runs 09:00 to 18:00 India time, which is 03:30 to 12:30 in the UK, or 04:30 to 13:30 while you are on summer time, so most of your morning overlaps with ours.

Quoted in GBP

Quotes exclude the 20% VAT in the UK, shown separately on the invoice.

Data protection

Work for this market is scoped against the UK GDPR and the Data Protection Act 2018, agreed before development starts rather than retrofitted afterwards.

Written scope

Every engagement starts with a written scope and a fixed GBP quote within 24 hours, so the price is set before work begins.

About Java Developers

Hire senior engineers for Java and Spring Boot backends: REST and gRPC APIs, microservices, batch jobs, and integrations with the systems you already run. You work directly with the developers on flat quotes, with a written scope, automated tests, and CI on every build. Choose one dedicated developer or a small product team, on a monthly rolling contract with no lock-in.

What the engagement includes

  • Senior engineers only. You work directly with the person writing the code, never an account-manager layer or an offshore handoff.
  • The backend fundamentals transfer directly: REST and gRPC API design, relational and NoSQL data modeling on PostgreSQL, MySQL, and MongoDB, Redis caching, and AWS deployment are the same disciplines whether the runtime is the JVM or Node.
  • A written scope before any code is written, so both sides agree on what done means and what it costs.
  • Automated tests (JUnit, Testcontainers, integration tests) and CI on every build, not tests bolted on at the end to tick a box.
  • You own the GitHub repo, the cloud account, and the CI pipeline from day one, so there is a clean handover or exit whenever you want it.
  • Flat INR quotes with GST for Indian clients, and USD, CAD, GBP, or AED via Wise for overseas teams. W-8BEN and LUT on file, 24-hour response.

How we work with UK clients

UK engagements tend to start with procurement questions rather than technical ones. Who holds the data, which law governs the contract, whether you can produce a record of processing if the ICO asks. We answer those in the proposal instead of leaving them to a legal review three weeks in, because that review is where UK projects usually stall.

Invoicing is the other thing worth settling early. We are outside the UK, so services we supply generally fall under the reverse charge and your finance team accounts for the VAT rather than paying it to us. Our invoices say so explicitly. We quote in pounds, the figure does not move with the exchange rate mid-project, and payment by bank transfer avoids the card fees that make a five-figure invoice unnecessarily expensive.

Questions UK clients ask

How does VAT work if you are based in India?

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.

Are you compliant with UK GDPR and the Data Protection Act 2018?

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.

We are a public sector body. Can you meet the accessibility regulations?

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.

Which law governs the contract, and what about IR35?

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.

Java Developers: common questions

How much does it cost to hire a Java developer in India in 2026?

Senior Java developer and agency rates in India typically run about 700 to 4,500 rupees per hour depending on seniority and system complexity. We quote flat INR with GST for project work and a fixed monthly rate for a dedicated developer, so there are no hourly surprises. Overseas clients are billed the equivalent in USD, CAD, GBP, or AED through Wise. Rates well below market for genuinely senior Spring Boot work usually signal juniors or hidden change-request fees.

Do you actually have Java experience, or is this a new service line?

We will be straight with you. Our highest-volume production work is in Node.js, Laravel, React, and Flutter, and Java is a service line we take on deliberately rather than a decade-long specialty. What we bring is senior backend engineering: API design, data modeling on PostgreSQL and MongoDB, Redis, AWS, testing, and CI, which are the disciplines that decide whether any backend holds up. If a project needs deep, specialized Java internals we are not the right team for, we will say so on the first call rather than after you have paid.

Should I hire a dedicated Java developer or a fixed-price project?

Pick a dedicated developer when the roadmap is still moving and you want to direct the work sprint by sprint. It is a monthly rolling contract you can stop with notice. Pick fixed-price when the scope is clear and you want a known number against a known date. Many clients start with a small fixed-price build to test how we work, then move to a dedicated developer or retainer once they trust the output.

Which Java and Spring versions do you build on?

New work goes on a current LTS Java (17 or 21) and the latest stable Spring Boot 3.x, with Maven or Gradle, and we containerize with Docker. For an existing system we meet the version you are on first, then propose an upgrade path if you are stuck on an end-of-life release like Java 8 or Spring Boot 2.x, phased so nothing breaks in one big jump.

Can you take over or modernize an existing Java codebase?

Yes, and it is a common request for a new team. We start with a short audit: a dependency and security review, a look at the build, the tests, and the data layer, and a written list of what is fragile and what to fix first. From there you can hand us the whole system or just the priority work. Because we deploy from your own repo and cloud account, nothing gets locked to us.
