SBD member company Siddall & Hilton, a UK manufacturer specialising in high-performance steel wire fencing systems, shares insight into an important development affecting perimeter security standards. With extensive experience supplying fencing solutions for critical infrastructure and high-security environments, the company works closely with specifiers and security professionals to ensure systems meet recognised testing and certification requirements.

In this blog, Siddall & Hilton highlight the implications of the National Protective Security Authority (NPSA) withdrawing testing against the Manual Forced Entry Standard (MFES). They explain what the change means for specifiers, manufacturers and installers, and why the industry is now relying on LPS 1175 as the active benchmark for assessing forced-entry resistance in security fencing.
