Just to note that the exemptions on this are quite easy to get. Right now, you only have to spend £3500. If it costs more than that to get to the required EPC rating, you can get an exemption. There is also the "seven year payback test", which is as it sounds. What this means is yes, this may drive your landlord to install LED bulbs and thermostatic radiator valves, and maybe some double glazed windows, but it's not going to trigger a mass drive towards modern insulation and solar panels. Personally I think we should just force landlords to bear the cost of heating to 18c.
