This comes from an article on coffee shops, attitudes to tax avoidance, and the commercial impact of the decision making companies and consumers face on this issue in the FT today:

[S]ome people prefer to patronise businesses with simple structures. The Fair Tax Mark – a Kitemark for “responsible” taxpayers based on questions about transparency and tax havens, was introduced to help companies set themselves apart.

A similar message can be sent out by individual business owners using the “Fair Tax Pledge”, a free, self-certified declaration of opposition to tax avoidance that was launched last Friday.

Richard Murphy, a tax campaigner who designed the pledge thinks it may appeal to proprietors of small coffee shops. He accepts it would not “make or break” a business but insists companies can benefit from the public's hostility to tax avoidance.

Others seem to agree with me:

AMT says its attitude is guided by its “ethical compass”. But Alistair McCallum-Toppin, managing director, imagines that the stance also brings “a bit of extra custom”. In his view, “today's hard-working, taxpaying customer is not supportive of [tax avoidance] and frankly, they'll go elsewhere.”

If you're in business and want to sign up to the Fair Tax Mark or Fair Tax Pledge please give them a look.

And yes, I am a director, but right now am unpaid and the companies are not for profit so I can't benefit in other ways either.
