How would my business qualify for the TaxTicked logo?
Your business would qualify if your effective rate of tax paid (not declared) is at least 85% of the headline rate of UK corporation tax. You will also need to make a declaration that your company (and directors): 
1)    do not use tax havens for the purpose of avoiding UK taxation
2)    do not use declarable tax avoidance arrangements, and
3)    are not considered high-risk by the U.K.'s HM Revenue and Customs.

My business sells services, not products. Would I still be able to use the Tax Tick?
Yes, by displaying it on your promotional literature, website, etc.

My company operates legitimately in the Channel Islands as well as on the mainland. Would it still be eligible for a Tax Tick?
Yes, as long as your offshore activities do not result in your company avoiding UK corporate tax.

What if my company is a multinational / is not headquartered in the UK?
It could qualify as long as your company is paying the tax expected of it on its UK earnings and does not use tax havens for the purpose of avoiding UK taxation.

What would it cost to get Tax Ticked?
First you would pay for an audit to establish your eligibility – the cost of which would depend on the complexity of your accounts. If you qualified, you could then license the Tax Tick for unlimited use for the next twelve months. It is envisaged that licensing fees would be between 1% and 2% of declared profits. This would pay for the scheme to be administered by a non-profit company and to publicise the Tax Tick among consumers.
