Purchase projects are subject to an improvement on emissions of 25% over the 2006 regulations.
Rental projects with an intended period of use of over 2 years need to comply with the regulations applicable at the date of their manufacture and will need bespoke L2A calculations.
This also applies to second hand sale. Rental projects under 2 years will be issued with a generic certificate supplied by the MPBA (Modular and Portable Building Association). Projects for construction sites remain exempt.
