Create assessment from EPC data? #409

Closed cagabi closed 5 years ago

cagabi commented 5 years ago

Could we offer MHEP assessments avoiding the site visit by using EPC data? I'd like to look into how to build an assessment from an EPC

ghost commented 5 years ago

Don’t even go there. EPC data is usually badly wrong!

Is that because EPC assessments are normally very old or because the procedure itself?

All of the above - plus people are paid £30/time to do them, so we shouldn’t expect the data to be accurate in the first place.

I would use them for stock level analysis - with caveats - not for individual houses when suggesting improvements.

Ok, fair points. I close this issue now

No worries. And sorry if a bit harsh - Helen and I have just spent too much of our lives already wrangling with bad EPC data.

There is a role for something like this though I think - doing a rough assessment without a visit.

It’s what the geovation tool is about - and we should probably look at that again sometime. (I trust OS maps and the person living in the house a lot more than I trust EPCs).
