GPDR/ICO registration. Do I need to register? (Their site is inconsistent.)

Question

https://ico.org.uk/for-organisations/guide-to-data-protection/guide-to-the-general-data-protection-regulation-gdpr/data-protection-fee/exemptions/ lists exemptions as:

Staff administration

Advertising, marketing and public relations

Accounts and records

Not -for -profit purposes

Personal, family or household affairs

Maintaining a public register

Judicial functions

Processing personal information without an automated system such as a computer. Since 1 April 2019, members of the House of Lords, elected representatives and prospective representatives are also exempt.

but https://ico.org.uk/for-organisations/data-protection-fee/self-assessment/y/N/Y/Yes/Yes lists the exemptions as only:

Judicial functions;

elected representative functions

personal, family or household affairs not connected to commercial or professional activities (including CCTV to monitor your domestic property, even if you are capturing images outside the boundaries of your property); or

to maintain a public register (ie you are required by law to make the information publicly available).

This feels like the ICO are deliberately overreaching in order to increase the number of £40/year fees.

Are they overreaching and how can I find out?

(Note: I'm happy to pay the £40/year fee if I'm legally obliged to. On principle, I don't want to pay if I am being misled by their website's self-assessment guide.)

Answer 1

Both of the pages linked in the question are from the ICO.

The other exemptions listed on the first page linked but not on the second, seem to be handled on other pages of the self-assessment tool. I have not tried to verify that every exemption listed on the fist page is properly handled, but that seems to be the case.

Which exemption do you think is included in the list on the fist page, but is not covered on the self-assessment tool?
