The sites theme seems to be related to health and safety training. Im assuming by improvement you mean from an seo perspective, so firstly do some keyword research based around your products and services. Modify the meta-tags (title and description) to reflect the chosen keywords, they currently relate to the company name and very generic terms which will not help. The meta-tags should be unique for each page and relate specifically to the page content. Based on the keyword selection; improve or enhance the homepage by including some of the keywords written within the natural page content. Work on acquiring some anchor text back links preferable from thematically related sites or directories. Insure that you request you chosen keywords to be utilised within the back link text. (don't buy links though) Just a few small pointers Good Luck
