I have mixed emotions on this. On the one hand, I feel sorry for the hundreds of LLs who actually believed this was going to be enforced (I never did) and sold their rentals.
On the other hand, I know from bitter personal experience that the EPC system is deeply flawed and not fit for purpose.
I'm glad I'm in a warm home this winter. My former LL was exceptionally wealthy (I'm not even talking 'just' a few million) and most of his homes just reached the legal E within 1 or 2 points with single glazing, faulty heating systems, no insulation, ancient boilers, vast voids under the floors, and so on. The energy we used in that house because of the deeply flawed EPC calcs was three times what the EPC said it should be.
They don't actually test anything, you see. And it's one size fits all no matter the location, which is absurd given the weather extremes from one end of the country to another.
It was costing us £650 a month when we left (our electricity was £200 a month on top of it). When the cost of oil spiked in March 22, we knew it would have been almost double that during the cold winter months.
Let me tell you - that £650 a month was barely enough to keep me warm enough to be able to even cook dinner. That house didn't hold heat for longer than 30 minutes, so even spending more and blasting the heating high was a fruitless endeavour.
So, I'm really quite sad that slumlords won't be held to account.
But, frankly, even if it had become law, it never would have been enforced, just like everything else in this country. It's nothing but lip service, ever. Enforcement of landlords with EPCs has to be applied for locally, and, if you're lucky, your local government might fund 1.5 people for 1 year to crack down on specific landlords illegally renting F+ homes, or those who haven't bothered with ratings.
That even that doesn't deal with the fact that what you see on a property rated E (and probably some Ds) is in no way based on the reality of the amount of energy that home actually uses.
I am glad the good, conscientious landlords will not have to sell up, but it still leaves a massive gap for those who just DGOS to take advantage and put people in balls off cold homes that are barely possible to heat because a piece of paper with a bunch of standard calculations says it is possible.
