Duplicate content on the homepage

[lcdesign]

Hello

SEOMOZ Is giving me an error on duplicated content on my site. When viewing the details it is showing the following as duplicated content

domain.co.uk/

domain.co.uk

domain.co.uk/index.html

Obviously these are the same pages. Why is it seeing them as seperate.

Does anyone know how I can resolve this issue?

Many thanks

This is known as  canonical issue. Search engines see these as three different pages.  You can fix this using 301 redirect.
