We do not have designated car parking spaces for visiting members of the public or non-pass holders, because of security concerns and pressure on space on the estate. The Serjeant at Arms Office is sometimes able to make special arrangements for parking by disabled visitors, if the limited number of slots provided for Members and staff with mobility problems are not all in use (for example on non-sitting days or during parliamentary recess). In such cases, special arrangements for security search are made. If parking on the estate cannot be provided, disabled parking spaces are available in the nearby NCP car park at Abingdon road (opposite the Black Rod Garden entrance to the estate).
