And then also we're going to go on to cover about the things that we need and things, good practice throughout the build process to get, one, a pass, but two, if your EPC rating is a... important things that you need to consider and again like all the things we generally talk about here at stroma being involved early is the is the best option and then sticking to the design when you when you design something had it assessed and then don't change your mind Yeah,

it should be noted that with the introduction of new building regulations, it's harder to get particularly EPC ratings because the costs of energy per kilowatt have gone up.

So before, previous regulations were in 2013, so costs were from 2012 levels.

So you're assessing a building in 2021, you're working on 2012 figures in terms of cost or how much it will cost to operate the dwelling.

So with the new regulations, the same specification, your EPC rating would significantly drop because the cost of energy has gone up.

But ironically, some of the costings have went down.

So for LPG, the same specification would go, you'll get a better EPC rating, but your emissions will go up.

Yes.
