About Us
About Duo Test Limited
Duo Test is an independent PAT testing and emergency light testing company based in East London, providing certified, reliable and affordable services across Essex, Kent and surrounding areas. We help landlords, schools, offices and industrial sites stay compliant with UK safety regulations through fast, professional testing and same-day digital certificates.
With over 5+ years of industry experience and more than 1 million individual tests completed, I built my expertise while working with one of the UK’s leading compliance providers. During this time, I was involved in large-scale projects for blue-chip companies, universities, hospitals and retail chains — learning how to deliver quality under strict deadlines and complex requirements.
In 2025, I founded Duo Test to bring that same professional standard to a smaller, independent business — one where I can focus on:
• Affordable PAT testing costs with clear, transparent pricing
• Attention to detail in every test, whether small appliances or industrial equipment
• Fast turnaround with same-day PDF reports and digital PAT testing certificates
• Personal service where clients speak directly with an experienced engineer, not a call centre
My mission is simple: to provide reliable, affordable and hassle-free PAT & emergency light testing services across London, Essex and Kent — with the professionalism of a large company, but the care and flexibility of a small one.
