the main driver of the bing search is the keywords meta tag. on your contact page, the keywords meta tag does not contain the key word contact:
<meta name="keywords" content="Removal Companies in Bexleyheath, Bexlyheath Kent, ASP Removals, ASP, Removals in Kent, Removals and storage, A.S.P, Furniture removals, Kent removals, Storage, Removal company, House removals" />
it looks like you have the same content for the keywords meta tag on all of your pages, each page should have unique keywords that pertain to that specific page in your site.
