I appreciate the importance of this issue, and the awful consequences which the use of asbestos has had for thousands of families over many years. Use of any asbestos in new buildings was prohibited in Great Britain by 1999 following earlier national prohibitions of the highest risk types. 
In respect of legacy asbestos present in older buildings, the materials need to be dealt with in the safest possible way with a clear plan in place for managing them including, where necessary, whether they need to be removed altogether. I understand that this is currently regulated by the Control of Asbestos Regulations 2012 (CAR).
CAR Regulation 4 requires those in control of non-domestic buildings to record the location and condition of any asbestos-containing materials and to put into place a plan to manage the risk they present. This of course includes Government and local authority buildings. The record of the location and condition of any asbestos, and management plan, must be available for as long as asbestos-containing materials are present in the building. 
I can assure you that the Government and the Health and Safety Executive take the management of asbestos very seriously, and will do everything necessary to minimise the risk to public health from asbestos exposure.
