NASC Launches TG20:21

September 15, 2021

NASC has launched the much-anticipated update to TG20:13 – the renowned scaffolding compliance software and guidance package. 

The new version – TG20:21 – replaces the 2013 version that was originally launched in March 2014, and all three elements of the package are now available online, as part of a subscription via the NASC’s.ePortal 

Existing TG20 users are able to take advantage of a period of free use, by using their TG20:13 serial number. The period of free use is a forerunner for the formal withdrawal of the 2013 version, currently proposed to be later this year, and in that regard, existing TG20 users are free to continue to use the 2013 version, for the short-term at least.


Dennis Brathwaite, NASC’s Technical Advisor, said: “Existing scaffolds constructed in compliance with TG20:13 and associated compliance sheets remain acceptable and do not require modification.

TG20:13 compliance sheets are still valid and may continue to be used for the next few months. It is anticipated that TG20:13 will be formally withdrawn, in favour of fully adopting TG20:21 in the Autumn.”

NASC has not clarified whether ongoing works should be reassessed for TG20:21 compliance, but We believe that TG20:21 compliance sheets will only be required for new work, after TG20:13 has been formally withdrawn, and therefore, existing TG20:13 compliance sheets will remain valid for the immediate future, as they will still offer a means of compliance with BS EN 12811. Any immediate requirement to adopt TG20:21 will likely be a customer specification, as opposed to one that has a basis in statutory compliance.
