Actually, might as well flounce.
It's odd how quickly it's changed. All through the nineties, they were compulsory. I worked with an old university friend for a while - just the two of us, in a serviced office cubbyhole - and we both wore ties.
Now, the etiquette is quite complex. You wear them if interviewing for a full time job, but not for contract or consultancy gigs. You wear them if you're presenting on behalf of your employer to a largeish audience or to new customers, but it would be rude to wear a tie when meeting an existing customer or contact: it would look as if you had some sort of agenda and weren't there to collaborate.
