I see new EPC standards are coming in 2025 so that a property has to be a C to be rented out, right now it is an E. All for net zero, of course. Estimates for the average of the 1.5million rented properties are that an additional cost of £4,000 will be needed to get from E to C, but for many the cost will be much higher, e.g. draughty old houses.
My understanding is that its only a proposal at the moment. Not definite. However, there are already many threads on this and other forums about it if you need more advice.
Even if the proposal isn’t adopted, it can easily be done by the back door, changing for criteria for the gradings. I just got E for a property that’s had new windows fitted, which got a C about 4 years ago when it had the old ones, which were in very poor condition.
I can only wish they reconsider. I wonder what will happen to the Victorian houses or those that have had loft conversion. Not exactly sure what more could be done to bring the epc to a “C”.
