The Subterranean Development Bill was originally an amendment to the Localism Bill sponsored by Lord Selsdon and drafted by members of the Pyramus & Thisbe Club.
The driving force behind the bill appears to be resident associations in affluent areas of London such as Belgravia and Highgate where many members of the House of Lords have properties.

The Private Member’s Bill was introduced by Lord Selsdon, read a first time in the House of Lords on 8th December 2011. At the bill’s second reading on 10th February 2012 Lady Hanham, the minister, indicated that it was unlikely that the Government would support new primary legislation and that the measures within the bill should be dealt with by providing Local Authorities with extra clout to enforce existing regulations:
“I hope I have made it clear that further legislative measures are unnecessary. However, we must find a way to ensure that all the issues that have been raised in the Bill are taken into account, to see where legislation may need to be updated.”
The next step will be to identify those regulations and I understand further meetings between members of the advisory committee and Government officials are continuing.
