How It Works
-

1. UPLOAD PLANNING DOCUMENTS
Find these on your local council’s planning portal by entering the planning application number, & upload all relevant documents from the applicant to Objector.
-

2. CHECK OBJECTION GROUNDS FOR FREE
Objector analyses the application against national (NPPF 26) & local planning policy. Find out if there are valid objection grounds & their impact ranking. If there are no valid grounds, we’ll advise you not to continue, and you’ll pay nothing.
-

3. GENERATE OBJECTION LETTER & TOOLKIT | £75
Generate your complete planning objection toolkit, including an objection letter, lobbying letter/video, & planning committee speech - all with planning policy references.
“Objector has been a very useful tool for our community. We used the platform to identify our ‘high impact’ concerns, & now feel empowered to challenge these issues.”
— The Moylgrove Community, Pembrokeshire
Why Choose Objector?
-
Purpose-Built for Planning
Objector is built specifically for the planning system — unlike generic AI. Three AI models, trained on planning policy, analyse your application against national and local policy, helping you find valid objection grounds that generic AI can miss or misinterpret.
-
Updated with the New NPPF (Aug 26)
In August 2026, the government rewrote the National Planning Policy Framework (NPPF). It’s even more complex and difficult to navigate than before. Objector has been updated with the latest planning laws, ensuring your planning objection includes the most current policy references.
-
Fast & Affordable
You often have just 21 days to object, and planning consultants cost £2,000+. Objector helps you find the strongest material grounds quickly and affordably. Check your grounds for free, then pay to unlock your objection toolkit only if you decide to proceed.
-
Policy-Backed Objections
Every identified objection is linked to the relevant planning policy, so you can see why it matters. Our AI Planning Policy Advisor can also explain complex planning policies and codes in plain English, so you know what you’re arguing and why your objections count.
-
Finds What Matters
Not every issue will influence a planning decision. Objector identifies and ranks the issues most likely to matter, helping you focus your objection on the strongest, most relevant planning grounds — rather than filling your letter with weak or irrelevant points.
-
The Result
A clear, evidence-based objection built around planning policy — not emotion or generic AI-generated arguments. Objector gives you the analysis, references and tools you need to make a stronger, more focused case that councils have to listen to.
“You can use generic AI to write your objection letter, but it's a bit like asking Dr Google for a diagnosis - you'll get an answer, but it probably won't be the right one...especially with the new NPPF now in play.”
— Hannah George, Co-Founder, Objector
