it does look better having an address on website and things but another widy mate of mine did this and he got taxi's and pizza's sent to his house all the time form bitter window cleaners.Only old folk seem not to like phoning mobile numbers so should not be a real issue in today’s world but for me I prefer to have both.
However don't know about you lads but I've defo seen an increase in travellers going around with sign written vans ripping ppl off so maybe ppl's perceptions on just displaying mobile numbers is changing. No address on websites, flyers etc may also ring alarm bells for some so if you run a legitimate cleaning business then your address should be on all promotional media, paperwork and website too in my book.
