What does the Act say about objecting?
The grounds that don’t require consent — protecting the data subject’s interest, public duty, and legitimate interests — are counterweighted by section 11(3): a data subject may object “at any time... on reasonable grounds relating to his, her or its particular situation, unless legislation provides for such processing”, and may object at any time, without reasons, to direct marketing by means other than unsolicited electronic communications (s 11(3)(b)) — electronic marketing has its own regime under section 69. The consequence of a valid objection:
“the responsible party may no longer process the personal information.”
The 2025 Regulations: objection channels
The amended Regulations (in force 17 April 2025) modernised the mechanics. Objections must be possible free of charge through accessible channels:
“by hand, fax, post, email, SMS, or WhatsApp and or in any manner expedient to a data subject”
A telephonic objection must be electronically recorded. The practical upshot: you cannot funnel objections through a single posted form any more — your channels must meet data subjects where they are, and your staff need to recognise an objection when it arrives by WhatsApp. The full set of 2025 changes is consolidated on the 2025 amendments page.
Handling an objection in practice
Treat every objection in four steps. Log it — date, channel, scope; record telephonic objections electronically. Classify it — marketing objection (always honoured, no reasons needed) or section 11(3)(a) objection (assess reasonableness against the person’s particular situation). Act on it — stop the affected processing unless legislation requires it or the objection is not reasonable; for marketing, suppress rather than delete, so the person stays suppressed. Confirm it — tell the person what you did. Marketers must additionally keep a database of objectors and leave them alone — the Regulator’s Guidance Note requires it, and ignoring opt-outs is exactly what earned FT Rams Consulting the first direct-marketing fine (see the enforcement tracker).
