I would agree with Normans points. Knowledge and experience is key. I go to houses in what could probably be classed as very casually dressed and it’s never done me any harm. Having the ability to get the customer to trust you is more important than how shiny your shoes are. In the past ive ruined two very expensive suits climbing into lofts!!!!
Although not too long ago I went to see a potential customer and before I even had the chance to send a quote he phoned to say he had placed his order with another company because and I quote ” the sales rep looked more professional in his suit” I couldn’t help but laugh. I then asked him 4 questions- what panel are you getting, what mounting system are you getting, what inverter are you getting and lastly what are you paying for it.
Answers were – not sure, not sure, not sure and £8995.
I then asked him is paying £3k more than you need to more important what clothes I wear. By the end of the conversation he had confirmed he will cancel and we got the job in the end and he was delighted because knowledge took over.
