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 & local planning policy. Find out if there are valid objection grounds & view their impact ranking of high, medium or low. If there are no valid grounds, we’ll advise you not to continue, and you won’t pay a penny.
-
3. GENERATE OBJECTION LETTER & TOOLKIT
Generate your complete planning 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 Objector?
-
Purpose-Built for Planning
Objector is built specifically for the UK planning system — unlike generic AI. Three AI models, trained on planning policy, analyse your application against national and local policy, helping you find valid grounds that generic AI can miss.
-
Specialist Planning Analysis
Planning consultants can cost thousands. Objector gives you specialist planning analysis in minutes. In a test against real planning officer reports, Objector identified 95% of key planning issues, compared with 61% for ChatGPT.
-
Fast & Affordable
You often have just 21 days to object. Objector helps you find the strongest grounds quickly, without the cost of a planning consultant. Check your grounds for free, then pay 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 in plain English, so you know what you’re arguing and why.
-
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...”
— Hannah George, Co-Founder, Objector
Object to Outline Planning or Full Planning Applications
Object to an Outline Planning Application in England
Facing a large-scale development? This is your first & often strongest chance to stop it before it starts.
Outline applications decide whether a development can go ahead in principle — before most details are fixed. Identify what can be challenged early, and submit clear, policy-focused objections that carry real weight with planning officers & make your community’s voice impossible to ignore.
Object to a Full Planning Application in the UK
Something not stacking up with a detailed plan? Challenge the details before they damage your home or community.
From a neighbour’s unsuitable extension to an unseemly change-of-use, challenge unfair or inappropriate proposals before it’s too late. Identify valid material objection grounds, and generate a policy-centred objection letter & toolkit, in minutes. Make your voice heard - in the language planning officers speak.
