.NET Developers 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.

Senior .NET developer and agency rates in India run roughly £6.3to £31per hour depending on seniority and scope. A dedicated senior engineer on a monthly retainer is usually in the £540 to £1,300 per month range, and scoped projects are quoted as one flat INR figure with GST included, so there are no hourly surprises. International clients are quoted the equivalent in USD, GBP, CAD, or AED. Rates far below this for genuinely senior C# work usually mean juniors or change-request fees added later.

We will be straight about it. Our shipped public work is strongest in Next.js, React, Node, Laravel, and Flutter, and .NET is a newer service line for us rather than a ten-year specialty. Our senior engineers are fluent in C# and ASP.NET Core, and the skills that decide backend quality (API design, data modelling, testing, and CI) carry over directly. Because it is a newer line for us, we are happy to start with a small paid trial sprint so you can judge the code before committing to anything larger.

Modern .NET on the current LTS, .NET 10, with .NET 8 fully supported for teams that need it. ASP.NET Core for APIs and MVC, minimal APIs where they fit, EF Core or Dapper for data access, and Blazor when the UI belongs in .NET. We deploy to Azure App Service, Functions, or Linux containers through GitHub Actions or Azure DevOps. We do not start new projects on .NET Framework or WebForms, though we are glad to migrate you off them.

Yes, and migrations off legacy systems are a genuine strength that transfers cleanly from our other stacks. We favour a strangler-fig approach: stand up modern .NET alongside the old app, move functionality across in slices behind a routing layer, and keep the business running the whole time rather than attempting a risky big-bang rewrite. We start with a short audit of the codebase, data layer, and dependencies, then hand you a phased plan with the risky parts sequenced first.

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