Our EPC when we bought the property was a D 64. With a potential of C 76.
We have since inadvertently taken of the steps and more. What does that do to our score and does it really matter?

Step 1- increased loft insulation to 270mm +

Step 2- floor insulation, none assumed but it turns out we have XPS under our floor slab

Step 3- low energy lighting, LEDs everywhere now

Step 4- solar water heating.

Step 5- solar PV, 2.5kWp, we have 6.7kWp

And now after all that we have replaced the oil central heating with a heat pump and started replacing 20 year old double glazing and frames with triple glazing.
To be eligible for the BUS grant we had to have an updated EPC, which has all gone through but the government website only shows the original.

Should our new score now be higher than the potential?
 
I found out why we didn’t get a new EPC. Our old one was suitable for the BUS. But given we paid for one with the heat pump install, we’re getting a new one. A company is coming out of Friday, I’ll let you know how that goes.

I could have told you that and the information is also out there :p You just need a valid EPC that's no more than 10 years old. Plus they're a huge waste of money and don't stand for anything, you just need a valid one when selling up.

Please don't just throw money at all these "low carbon" fixes willy nilly. Think strongly about real world payback and if you'll be there to see the benefit.

How old is your house? I'd highly recommend a USB-C phone FLIR type camera. You may have cold bridges and drafts in certain areas that can be identified and remedied, making a huge difference compared to the trivial cost. I think mine is a Topdon and was just over £200.

Ah see my understanding was that as we didn't have enough loft insulation as per the old EPC, we'd need to address that, then get the EPC to satisfy the BUS.
 
@Derek W
Appreciate the quality post.
Can an EPC assessor carry out a SAP calc? We had an extension done, with a lot of triple glazing and the building inspector is waiting for the builder to provide SAP calcs. Just thinking outside the box, maybe I can get them done at the same time as an EPC?

Wrt to the floor slab, I have seen the insulation, we have pics of it.
 
EPC is back.
Previous score / potential was 64/76

New one is 72/80

Couple of points I find odd.
1) Air source heat pump is only ‘good’
2) ASHP provides hot water, immersion for legionella cycle. They’ve written ‘HW is via immersion -average’
3) recommended zoned heating control. AFAIK that was an inefficient way to control an ASHP
4) Recommended 2.7kWp solar. We already have 6.7kWp.
5) No acknowledgement of the huge triple glazed panels we now have. Just ‘fully double glazed -good’
6) ‘ Main heating- underfloor, electric - good’. We have 80m^2 of wet UFH downstairs and 2m^2 of electric UFH in the en suite. Not a main heat source.

Whilst I accept it doesn’t really matter, this guy has annoyed me!
Let me know your thoughts as to whether I’m being reasonable or not before I contact them please :)
 
After a little back and forth with the assessor they have amended my report.
Now a B 87 with a B 91 being possible if I were to have zoned heating control for the heat pump and solar diverter for domestic hot.

I still disagree with the zoning, as do Heat Geeks but the EPC guidelines say I should be zoned.

Also, somehow we’re producing 2.1t of CO2.

They still have my domestic hot listed as immersion- off peak. Like I’ve stated several times, it is heated by the heat pump, the immersion is for legionella cycle only.
