UK HSE Standards

ITDA UK were orginally approved in 2005 after an audit from UK-HSE and we rewrote many UK standards in order to gain approval for our Sports Diving and Professional programs... We have maintained our status since with annual updates and compliance with UK HSE Diving regulations... Which also includes EU Directives...

Please NOTE after Brexit things may change with ITDA UK and being a part of ITDA Europe.... Watch this space for updates...  We are looking a forming a corporation in Ireland to meet the new needs... Plus we have introduced a move to make ITDA a membership organisation from Sept. 2021  ITDA Membership System link...
