Pressleys was awarded Retailer of the Year at the Johnston Press South Business Awards 2013 on Friday night.
The awards, which were held Grand Hotel in Brighton and hosted by TV personality Fred Dinenage, recognise local business talent in the Sussex and Hampshire area.
Pressleys managing director Jonathan Pressley said: "The staff are delighted to have the recognition as in recent times they have had to dig deep whilst the business has grown rapidly.
"We received a special mention for our courage to increase our offering in Chichester with the opening of another two shops, whilst also helping to lift Worthing town centre and community."
Pressleys has stores in Chichester and Worthing.
