Figured out a quick fix and it seems to work.

in /skin/common_files/modules/One_Page_Checkout

modify

opc_profile.tpl

above the line that reads;

{include file='modules/One_Page_Checkout/profile/address_info.tpl' type='B' hide_header=true first=true}

add the line;

{include file='modules/One_Page_Checkout/profile/personal_info.tpl' first=true}

a few lines down rem out the same line;

{* {include file='modules/One_Page_Checkout/profile/personal_info.tpl' first=true}
*}

Then in 'User Profiles' ensure that you have got 'Company checked as active in the column 'Customer at Checkout'.

might need tidying but hey ho - I'm not a programmer.
