Conversion
GasSim 2.5 was launched in 2012.
The Environment Agency now expects gas risk assessments to be completed using GasSim 2.5
You are free to continue to use GasSim 2 under the terms of the GasSim 2 Licensing Agreement beyond the date of withdrawal of help desk support, although we recommend that all GasSim 2 users convert to GasSim 2.5 (at no cost).
