Electricity company - automatic backlinks from tables embedded on third party websites

[McTaggart]

Hi guys, I'm working for an electricity company and they want businesses to embed "live energy saving tables" where they choose to, on their website - each table links back to the electricity company.

Now I'm only comfortable with editorially given links these days, rather than "you choose to embed this table and it will link back to us - that's the arrangement" set ups - even when they're not using anchor text.

What are your thoughts?

Thanks, Luke

I would make the links no follow. I think you could find yourself at risk for a penalty if you do not, it really just depends on how widely it is spread. But I would include the links, because they would generally be deemed helpful Especially for someone wanting a table of their site. But I would make them nofollowed links as well just to protect yourself.

My thought make all links NoFollow or using this meta tag :

Place between and  page you put links. For example : yoursite.com/tables.html
