Welcome to our Declaration of Performance (DoP) document portal for Laidlaw products. If you require a DoP for a manufacturer’s branded product – please refer to the manufacturer’s website. You can filter either by product category (e.g. hinges, door closers) or search by the product code (SKU) or by the DoP reference number. You can read or download the PDF for reference. If you have any problems, please call our technical helpline on 01902 600400.
