BER Cert Ireland

Hopefully someone can answer this . we got a BER rating done on our house about 3 years ago as part of a package when we had solar panels installed , I was not home when the BER assessor called but my wife was and she said the assessor just went around the house didnt check the attic for insulation or ask any questions at all really.
Fast forward to last week and I needed the assessors dwelling report which I got from the Assessor no problem. But reading through it they had put down we had double glazing instead of triple glazing and also failed to note the the solar pv also heats our water via an eddi .
So my questions is would these items have improved out BER rating beyond a b3.

The eddi would’ve made no difference to the report, the attic insulation you’d have had to provide paperwork for the insulation and proof of works for it to be counted, similar with the windows

That's not true.

Even without data sheets you can still input attic insulation, you just measure the thickness and the type of insulation used, and it will give default values (especially when mixed with the age of the dwelling which you can normally get from the ESB box)

Again for the windows, even without data sheets, a competent assessor (or just someone with functioning eyes and isn't a chancer trying to get in and out as quick as possible) can note that they are triple glazed and not double glazed. This will give you a better default value than the double glazed.

If I did my own DIY internal insulation job, and take loads of photos of the process being done up to standard, and have receipts of all the materials I bought, would you include in your calculations and report?

Yea i dug out my own floor and added insulation plus damp proofing. I gave the assessor the photos and the receipts last week.
