Strategic Industrial Locations (SILs) are London’s main reservoirs of industrial and related capacity. There are two types of SILs: Preferred Industrial Locations (PIL) and Industrial Business Parks (IBP). Development proposals within or adjacent to SILs should not compromise the integrity or effectiveness of these locations in accommodating industrial type activities. The GIS files show the indicative boundaries, please contact the relevant London Borough to confirm accuracy. NOTE: The boundaries are based on Ordnance Survey mapping and the data is published under Ordnance Survey's 'presumption to publish'.Contains OS data © Crown copyright and database rights 2019.
