We are a UK-based, independent laboratory, recognised by ASTA for low voltage and high voltage testing and assessed against the requirements of IEC 17025. We have three in-house ASTA observers and offer full certification to cover all areas of design to be verified by test according to IEC 61439, making us the laboratory of choice for customers wanting to access global markets through certification of their products.



kA Testing Facility is part of the Encompass Group, established in 1956. The laboratory was originally set up to provide temperature testing services as an add on to our products, but soon grew to become the only ASTA accredited low and medium voltage laboratory in the UK.


Every member of our team is an expert in their field. Our two ASTA observers are responsible for the proper conduct of tests made under the aegis of ASTA and for the accuracy of the recorded test results and their presentation, so you can rest assured you’re in expert hands.


At kA Testing Facility, we believe that all customers, employees and suppliers should be respected. We are also proud to help our customers to innovate, and are pleased that they continue to place trust in us and challenge us so that we can continue to improve.
