Finance Bill

This issue is a long-standing subject of debate. Following what was said by my right hon. Friend the Member for Berwick-upon-Tweed (Sir Alan Beith), may I suggest that it would be helpful to hear from Ministers later whether they have considered revenue-neutral ways of taxing renovation as opposed to new build? Are there not very good environmental reasons, very good energy-saving and green reasons, and very good land use and planning reasons, for continuing to use existing sites rather than building on new greenfield sites?
