I'm not aware of any corporation tax relief for donations to CICs. Have a look at social investment tax relief, although this is only available to individuals and not companies.
thanks for your quick reply after reading both your articles and doing my own research its talking about lending money or buying shares more than products or services. from what I have interpreted corporate companies will still get social investment tax relief and it will be at 30%
My understanding of SITR is that it's only for individuals (income tax and capital gains tax) and not available to companies.
The benefits for donating to a CIC are widespread, though, even if not directly financial. You could sort out a sponsorship arrangement with a commercial company so they get good publicity for donating to your CIC.
