1) Be sure to include “About” and “Contact” pages.
2) Left-justify your text, rather than centering it. Centered text can be difficult to read. Additionally, it looks unprofessional.
3) The text on your “Terms and Conditions” page is a single paragraph. That should be broken up into multiple paragraphs and H2 headings for the section titles (“Free Home Visit & Professional Advice”, “Same/Next Day Service”, etc.) This will improve both the readability and your SEO.
