Councils need to know representations come from real, identifiable people — partly to weigh local impact, partly to prevent campaigns of fabricated objections. That's why comment forms ask for name and address, and why unattributed letters tend to go nowhere.
Can I object to planning permission anonymously?
Anonymity and confidentiality are different requests. You usually can't be anonymous, but you can often limit what's published: many councils redact addresses and signatures by default, and most will consider a request to withhold further details if you have a genuine reason, such as safety concerns.
If your worry is a neighbour's reaction, remember that the substance matters more than the author. A calm, factual objection about daylight or overlooking reads the same whoever signed it — and material points must be addressed regardless of any friction between households.
Community routes offer practical cover too: objections raised through a residents' association, a parish council, or your ward councillor carry a collective name rather than only yours.
Whatever route you take, stick to material considerations. An identified objection about a real planning harm achieves more than an anonymous one about anything — because the anonymous one may never be counted at all.
