BoJo going on about a risk matrix being introduced for buildings sub 18m. the devil will be in the detail but I suspect this will release most flats from the mess while condemning some others. Fingers crossed, as you say.
What baffles me so far is the lack of knowledge on this subject. I only really know of the detail due to what you've written here. However my sister is in the process of looking at properties (including flats) and shes since mentioned this to a number of estate agents who are completely unaware.
It shouldn't have to be this way but it appears to be the only way to get these things resolved. Fingers crossed.
