On the Default Sort the listings are ranked by a combination of homecare.co.uk Review Score and homecare.co.uk subscription level. The paid Platinum, Premium and Enhanced listings are listed above the non-paid Basic listings. The Platinum listings receive a Ranking Boost over the Premium and Enhanced listings, and the Platinum listings also have a more prominent styling applied to them.
You can also sort by 'Highest Review Score' (listings with Highest Review Score are shown first) and 'A-Z' (listings shown in alphabetical order). The 'Highest Review Score' and 'A-Z' sorts ignore subscription level.
