Rating (Empty Properties) Bill

I apologise to my hon. Friend for my absence at the beginning of his speech, and commend him on the authoritative way in which he is presenting a Bill that I hope and believe Members on both sides of the House will approve. However, concern has been expressed to me about property regeneration schemes, many of which are only just commercially viable or will not be so for some years. It has been suggested that the change in the system may well affect their viability. Has the Minister considered that, and is it a concern that has been expressed to him?
