The Scottish building regulations are due to be updated from Section 6 2010 to 2015 in October 2015. Until that date, SBEM version 4.1.e should be used for Scottish Section 6 EPC and Compliance calculations - i.e. these calculations should be carried out in Hevacomp v25 (with the final update, 29).
Please see further details from BRE here:
Hevacomp v26 will be updated to include the new Scottish regulations as the 2015 (SBEM 5.2f) changes come into effect in October. Should you wish to run any demonstrative, evaluation or test calculations under the new regulations at this point, then you will need to use iSBEM_5.2.f, which is available for download here.
Further information about the Hevacomp v25 / v26 switchover can be found here.
