You are including two jquery versions in your theme:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.js" type="text/javascript">
and
<script src="http://ukconservatoryblinds.com/wp-includes/js/jquery/jquery.js?ver=1.6.1" type="text/javascript">
While first one seems to be added in the theme and second one is added by the vSlider. Please see the below example to include jquery into your WordPress theme "The Right Way".
Add the below function in functions.php to avoid such conflicts and do not explicitly include jquery in your theme.
<?php
function my_scripts_method() {
wp_deregister_script( 'jquery' );
wp_register_script( 'jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js');
wp_enqueue_script( 'jquery' );
}
add_action('wp_enqueue_scripts', 'my_scripts_method');
?>
