Our story
Founded in 2016 to be a Quality Intelligence Partner — not just a bug-finding service.
TestDel has a proven track record of delivering large-scale software testing programmes globally. From day one our commitment has been to technical excellence — delivering projects on time, to the highest quality standards, with transparent reporting your stakeholders can rely on.
We are a specialist QA firm with enterprise credentials across financial services, public sector, aviation, energy, and technology. Our global delivery model combines UK-based engagement management with highly experienced testing teams across five locations — giving clients senior expertise with blended rates that compete against in-house costs.
We work across the full testing spectrum: manual and exploratory QA, test automation (Playwright, Cypress, Selenium), performance testing (k6, JMeter), security testing (OWASP), and accessibility (WCAG 2.2). Whatever your quality challenge, our 73 specialists have delivered it.

Who we work with
The right QA partner for three distinct buying situations
Independent QA evidence for compliance deadlines
Financial services, NHS suppliers, energy companies, and other regulated businesses need documented, independent test evidence. FCA, PCI-DSS, GDPR, DORA, DSPT — our consultants know the frameworks and deliver sign-off-ready evidence packs.
Automation frameworks that let engineers focus on product
Growing software teams burning engineering time on manual regressions, or facing enterprise procurement requiring a credible QA process. We build Playwright, Cypress, and Selenium automation that runs in your CI/CD pipeline from day one.
Senior UK-based specialists on flexible terms
System integrators and large enterprises running multi-workstream programmes with QA gaps. Our UK oversight and India delivery model gives programme teams senior, domain-experienced testers with competitive blended rates — no long-term commitment.
What makes us different
Senior-only delivery
Experienced testers with domain knowledge — from FTSE 100 banking to NHS digital to aviation. No junior-for-senior swap-outs once a project is signed.
Full-spectrum testing
QA, automation (Playwright, Cypress, Selenium), performance (k6, JMeter), security (OWASP), accessibility (WCAG 2.2) — one partner for every quality need.
UK oversight + global delivery
UK-based engagement management combined with experienced teams across 5 global locations. Senior quality with blended rates that compete with in-house costs.
Embedded, not siloed
Our consultants join your standups, your Slack, your sprint ceremonies. Testing that reflects real-world usage — not black-box validation from a distance.
