When you have seen a few 747's descend to their MDA over central London because they have been told "cleared ILS approach" you very soon learn to use the phase "when established localiser descend on ILS". Keep your licence safe.
I wonder, why UK can't just publish approach charts with corrected, higher FAP altitudes (not colliding with neighbour procedures). ATCO is still allowed to vector a/c below these altitudes (see MRVA) if needed.
