BSI Kitemark

BSI Kitemark: Cable Testing Verification

We were the first company globally to achieve the BSI Cable Testing Verification Kitemark, and we remain proud to be able to test our cables under this important accreditation from the British Standards Institution (BSI). It's a rigorous testing programme that gives cables a valuable third-party approval demonstrating quality and compliance.

The value of the Kitemark

Globally recognised, the BSI Kitemark is a symbol that commands respect. Over 82% of UK adults recognise both the Kitemark and understand what it stands for:

Safety: 93% believe a Kitemark product is safer
Quality: 91% say the Kitemark gives the reassurance of quality
Trust: 88% have more trust in Kitemark products
Reputation: 88% believe a Kitemark product comes from a reputable company

BSI Kitemark approved cables

Linked to the testing capabilities of The Cable Lab, under the BSI Cable Testing Verification Kitemark programme we can test a wide range of cables against the relevant British and European standards. As standard, we test and Kitemark specific cables that are in frequent use but are not covered by other assessment bodies. This includes our entire range of Medium Voltage cables, as well as the H07ZZ-F and N2XH Enhanced. These, and others included under the Kitemark, hold no other third-party approval and yet are frequently used in installations where quality and compliance is paramount.

As with all third-party marks, we recognise the value the Kitemark holds in domestic and certain international markets, and by testing under this intensive programme we can support our customers with the quality and compliance assurances they seek. 

Large Scale Projects - Kitemarking all cables

Having the assurance that all the cables used on a project are Kitemarked with this third-party mark of quality, compliance and performance can be invaluable on high-profile, critical, and quality-conscious installations. The uniformity of assessment emphasises the due diligence in specification and selection.

The extensive remit of our Kitemark accreditation means we can do just that: provide cables direct from our stockholding, all tested and confirmed as meeting the same exacting and rigorous standards, across the breadth of a project's requirements. It demonstrates a clear and dedicated commitment to cable compliance and excellence.

The Kitemark testing programme

For a particular cable to hold Kitemark approval it requires The Cable Lab® to test the individual components of every batch of cables made available for sale. That means every size and every core configuration within a cable range are tested prior to being released to our customers. 

The British and European standards for the cable as a whole as well as for each component layer, from the conductor resistance to the outer sheathing tensile and elongation measurements, are determined and measured. The methodology for testing is determined and controlled by our ISO/IEC 17025 accreditation. Testing criteria obviously depends on the individual cable construction but the in-depth analysis means our experts can verify and confirm the performance and safety criteria required of the product. It is only once this is completed can a cable be marked as holding the BSI Cable Testing Verification Kitemark.
