The Society in Jan 2014 counted over 200 A-boards within the city centre. In the right circumstances a few A-Boards can have a positive benefit in attracting custom to smaller and often independent shops. But 200+ is too many!
However, their use is deprecated by the Chichester District Council – see their guidance on ‘Shop Front and Advertisement Design’ here. Alternative business signage to A-Boards is being developed by the Chichester Business Improvement District (BID)
