These barriers are installed for the safety of the occupants and are designed to withstand horizontal loading as prescribed in British Standard (BS) 6399: Part 1 - Loading for buildings.
You are strictly not allowed to remove these barriers unless they are found to be damaged or not in good conditions. If there is a need to replace them, you shall engage a Qualified Person
