Showing HTML Code for Excerpts

I know that in general, html is stripped out of Excerpts. Is there anyway, I can get it back in?
The current website shows the Services to have no bullet points (3rd Section)

My Web Designer wants to have it showing the bullet points

I've tried the code here

But it seems to have no effect. Any advice?
