Top 5 Mistakes to Avoid in Your Planning Objection Letter


When it comes to objecting to planning permission, the devil is often in the details. A well-crafted objection letter can be a powerful tool in influencing the decision of your Local Planning Authority (LPA). However, mistakes in your letter can weaken your case and potentially lead to the approval of a planning application you strongly oppose. This blog post aims to guide you through the top 5 mistakes to avoid when you object to a planning application, with a focus on planning permission objections from neighbours and examples of objections to planning applications.

Mistake 1: Failing to Understand the Planning Process

Why It’s a Mistake

Understanding the planning process is crucial when you’re objecting to planning permission. Failing to grasp the timeline, key players, and decision-making criteria can result in missed opportunities to voice your concerns effectively.

How to Avoid It

Educate yourself on the planning permission process. Know the deadlines for submitting objections and the criteria that LPAs consider when reviewing applications. This will enable you to submit a timely and relevant objection.

Mistake 2: Using Emotional Language

Why It’s a Mistake

While it’s natural to feel passionate about changes in your community, emotional language can undermine the credibility of your objection. LPAs are looking for factual, reasoned arguments against a planning application.

How to Avoid It

Stick to the facts and use evidence to support your claims. For example, if you’re concerned about increased traffic, cite studies or data that demonstrate the potential impact. This approach is far more compelling than simply stating that the development will “ruin the neighbourhood.”

Mistake 3: Ignoring the Power of Collective Action

Why It’s a Mistake

Individual objections can be impactful, but there’s strength in numbers. Ignoring the power of collective action can result in a weaker overall objection to the planning application.

How to Avoid It

Engage with your neighbours and community members who share your concerns. Collective planning permission objections from neighbours can carry even more weight in the decision-maki

ng process. Coordinate your efforts to submit a joint objection or multiple individual objections that highlight shared concerns.


Mistake 4: Failing to Provide Examples

Why It’s a Mistake

General statements like “this will be bad for the community” are less impactful than specific examples. Without concrete examples of objections to planning applications, your letter may lack the persuasive power needed to influence the LPA.

How to Avoid It

Provide specific examples that illustrate your points. If

possible, refer to similar cases where an objection led to the rejection of a planning application. This not only strengthens your argument but also shows that you’ve done your homework.

Mistake 5: Overlooking Formal Requirements

Why It’s a Mistake

Ignoring formal requirements such as deadlines, formatting, and submission guidelines can result in your objection being dismissed outright.

How to Avoid It

Pay close attention to the LPA’s guidelines for submitting objections. Make sure your letter includes all the required information, such as your name, address, and the planning application reference number. Submit your objection before the deadline to ensure it’s considered in the decision-making process.


Objecting to planning permission is a nuanced process that requires careful attention to detail. By avoiding these common mistakes, you can craft a compelling and effective objection letter that stands a better chance of influencing your Local Planning Authority’s decision. Remember, the key to a successful objection lies not just in the number of voices raised, but in the quality and validity of the arguments presented. Whether you’re objecting individually or as part of a group, make sure to leverage the power of factual, well-reasoned arguments to make your voice heard.
