The ICO has announced changes in the annual data protection fee, payable by controllers of personal data (some non-profits can claim an exemption but many choose to register and pay anyway).
The increase is 30% but for smaller organisations that is only an increase from £60 to £78 per year.
You can find out more, and the increase for your size of charity, by visiting https://ico.org.uk/for-organisations/data-protection-fee/changes-to-the-data-protection-fee/.
