Welcome to the Q&A Forum

Hi AJ. I was able to verify your site is indexed in google.co.uk. I disabled the flash on my browser and can see your html code appearing normally. It looks like you have a WP site with both Yoast and the All in One SEO plugins. There are some conflicts you should resolve. Currently your page has two meta descriptions and three canonical tags. These extra tags are not the root cause of your current issue, but they should be cleaned up. With your site indexed and your home page not showing up in SERPs for even targeted phrases this leads me to consider that your site may be under a penalty. I wish I could look at your site further but an issue just came up and I need to leave my office.
