What is Planning Permission and Why is It Necessary?

Planning permission is a very crucial step taken by a local authority. It ensures that every renovation or construction plan adheres to all the necessary rules. However, it verifies that your plan designs align with building rules, seamlessly fit in with the area’s development rules, and keep safety on top. Thus, it’s a sign that your construction project meets all the guidelines before you start working on it.

Types of Projects That Require Planning Permission

Planning permission is perceived as easy, but it applies to a wide spectrum of renovation and construction, you might imagine. One must know how long does it takes to get a planning permission to build a house and prepare early. Let’s understand some common situations that need approval from your local authority:

  • Building Extensions: If you are planning to add an extra room, garage, or conservatory, you need planning permission. The need for approval is checked by factors such as location, size, and impact on the neighboring property.
  • Loft Conversions: Planning permission is required when you are planning to convert your attic into a living place. For such permission, responsible factors are adherence to fire safety, changes in the roofline, or affecting your neighbor’s privacy.
  • Demolitions: If you are planning to demolish a building, planning permission is required. The factors that work here are the historic building, posing potential safety risks, or being a part of a conservation field.
  • New Builds: Planning permission is always needed when building a new home, bungalow, or any other permanent living space from scratch. This guaranteed compliance with integration, building regulations, and zoning restrictions with the surrounding environment.
  • Changing the Use of a Building: You need planning permission to convert your commercial space into a residence. This guarantees that the new house matches with local development plans and does not affect the surrounding environment.

Tips to Ensure Your Application Is Processed as Quickly as Possible

While submitting a planning application, remember that efficiency is required to avoid any future delays. The following are some tips to make sure your application is processed as quickly as possible:

  • Seek Pre-application Advice: It is recommended to discuss your plans with your local authority before submitting your application to avoid any potential issues and ensure your application is complete.

  • Respond Promptly to Requests: If you have been asked to add extra information by the local authority, respond instantly to prevent delaying the processing of your application.

Avoiding Delays in Your Planning Application

To check whether your planning permission application is processed smoothly, avoiding any potential common delays is crucial. One of the best ways to prevent any delays is to ensure your application is detailed and has all the information and documents. Incomplete applications frequently result in requests for extra information and increase the overall time.

While you have gone through the ways to streamline your planning permission application process, any potential delays or future refusals can still arise. Let’s check how to navigate these issues: 

Understanding the Reasons Behind Delays and Refusals

Any refusal or delay in your planning permission application may arise for several reasons. Knowing these reasons helps in addressing the problems properly. Some common causes are:

  • Incomplete or Inaccurate Application: If there is any error or the information is missing from your application, it might be refused or delayed. So, check properly that your application is complete and correct.
  • Concerns from Stakeholders: There may be objections from neighbors or others, resulting in refusal or delays. Any concerns raised by stakeholders need to be addressed so that a solution comes out of it through compromise or negotiation.
  • Non-compliance with Regulations: If you fail to follow the planning rules or guidelines, your application may get refused or delayed. So, be aware of the relevant rules and ensure you meet all the requirements.

Steps to Take If Your Planning Application Is Not Progressing as Expected

  • Contact Your Case Officer: Don’t hesitate to reach out to your local authority case officer. Tell the officer everything and seek clarification on the issue and the reasons behind the refusal or delay. Openly communicating with the officer assists in knowing what is required to be done to go ahead.
  • Consider Revisions: Don’t get instantly discouraged if your application gets refused. Try revising the application based on the feedback you received and resubmit your application.
  • Appeal the Decision: You have full right to appeal a planning refusal to the Planning Inspectorate, an independent body that reviews every planning decision. All this procedure includes submitting an appeal form and potentially attending a hearing to present your case. So, be careful regarding the potential house renovation cost and further implications of an appeal before proceeding with your application.
