On 5 September 2012 Harlequins announced that they had begun a programme of significant investment in upgrading Twickenham Stoop Stadium. All four of the stands have been deep cleaned, this has included the installation of anti-roosting netting that features an unobtrusive fine mesh, secured high in the stands that will prevent damage to the seats and decking caused by the local pigeon population. Replacement of the broken or sun-bleached seating has also commenced and eventually all seating will be replaced block by block in a rolling programme over the coming seasons. The public areas of the stands, including the toilets, are also in the process of being decorated and upgraded. Four new turnstiles have been constructed at Gate 3 by the corner of the South and Etihad Stand to improve access and a new PA system to improve sound quality throughout the stadium. The hospitality facilities in the Etihad and LV= Stands have also undergone renovations and redecorations. Among the major improvements about to begin is the resurfacing of the North car park.
