Hi could someone advise whether there is an issue with the files when running PartL for SBEM. The exact same model run for English and Scottish Regs appear to be the wrong way around as the the Scottish Section 6 Regs require a larger carbon reduction compared to the English part L2 regs. However, the TER for England is significantly smaller compared to the TER for Scotland.
There are no issues that I am aware of. As you say, I would expect results for each of the regulations to be different, however as we have no part in the calculation method after the Hevacomp PartL input file gets processed by SBEM it is difficult for us to comment on such results. I would suggest that your accreditation scheme provider and/or BRE may be better placed in this regard.
However I can take a look at your project and compare the two input files to see if there are any differences, to rule out any Hevacomp issue - please zip the project folder and upload to this link.

Thank you Shane i've sent you over the file for you to have a look at. Do you happen to have contact details for BRE?
I have just downloaded the files and will be in touch. The best way would be to use the Feedback section on the NCM website:
I've been inspecting each project and can see no issues here - the PartL input files for both are practically identical, except for references to the differing regulation types.
From then on it is up to SBEM as to the results, so as mentioned BRE or your accreditation scheme provider are the people to consult on this.
