Applications & Permission

At SCL Design, we offer a variety of planning application services to meet your unique project needs. Each type of application serves a different purpose and requires specific expertise.

Certificate of Lawfulness
A Certificate of Lawfulness is required when you want to confirm that an existing or proposed development is lawful and does not require planning permission. This application is often used to verify that small extensions, loft conversions, or certain uses of land comply with current regulations. SCL Design helps you gather the necessary documentation to prove that your project meets legal standards, ensuring peace of mind for future developments.
Prior Approval
Prior approval is necessary for certain types of permitted development, such as larger rear extensions, certain change of use applications, and agricultural developments. This type of application allows local authorities to assess specific aspects of the project, such as its impact on neighbouring properties or local infrastructure, without the need for a full planning application. Our team at SCL Design ensures that all necessary documentation is submitted, helping to expedite the approval process.
Full Planning Application
A full planning application is required for larger or more complex projects that don't fall under permitted development rights, such as significant extensions or new builds. This process involves submitting detailed architectural plans and reports to the local authority, who will assess the proposal’s impact on the area. SCL Design’s experienced planners and architects guide you through the process, ensuring your application stands the best chance of approval.
Householder Planning Application
A householder planning application is typically required for smaller domestic projects, such as extensions, loft conversions, or alterations to your home. If your project exceeds the limits of permitted development rights, this application is necessary. At SCL Design, we help you prepare a thorough submission, including drawings and documentation, to make sure your project complies with all planning rules.
Thames Water Build Over Agreement
If you plan to build over or near a public sewer or water main, you will need a Build Over Agreement from Thames Water. This ensures that your development does not interfere with access to essential water services. SCL Design assists with the application and liaises with Thames Water to ensure your project meets all necessary requirements while avoiding delays.
How it works

Our Process

At SCL Design, we follow a streamlined, four-step process to ensure your project is managed effectively and efficiently.

Enquire

The first step is to contact us with details about your project. Whether it’s a house extension, a change of use, or a new build, we’ll gather initial information to understand your vision and requirements. This helps us determine the most suitable type of application for your needs.
approx. 2 hours

Research

Our team will then conduct a thorough research phase, lasting around two hours. We’ll review local planning policies, restrictions, and any relevant regulations that apply to your project. This step ensures that we have a solid understanding of the feasibility and potential hurdles your project might face.
approx. ½ hour

Phone Consultation

After our research, we schedule a 30-minute phone consultation to discuss our findings with you. During this conversation, we’ll review your project goals, advise on the most appropriate planning strategy, and answer any questions you may have about the process.

Appraisal Report

Finally, we’ll prepare an in-depth appraisal report that outlines the feasibility of your project, planning risks, and the steps needed to secure approval. This report provides a clear roadmap for your project, ensuring transparency and setting realistic expectations.
