Certificate of Lawfulness vs. Planning Permission: Unraveling the Architectural Maze

Understanding the Difference

If you’re planning to undertake a building project, you’ll likely have come across terms such as ‘Planning Permission’ and ‘Certificate of Lawfulness’. But what’s the difference between the two?

To put it simply, a Certificate of Lawfulness confirms that the development or use of a building is legal, while Planning Permission is a formal approval from the council for a proposed development. Let’s delve into these concepts further.

What is Planning Permission?

Planning Permission is a green light from your local authority to carry out building work. This is often required for substantial developments such as a new build house, house extensions, renovations, conversions, loft conversions, garage conversions, barn conversions, and even driveways. It’s the first step to amending planning permission, applying for planning permission, and securing planning approval.

If you’re wondering whether you need planning permission, our team of Architectural Designers is here to assist. We can guide you through the gov planning portal, helping you understand if your project falls under full planning permission or permitted development.

Certificate of Lawfulness: What Is It?

A Certificate of Lawfulness (also known as a lawful development certificate) is slightly different. This document verifies that an existing or proposed use of a building, or any building operations, are lawful. This isn’t the same as planning permission, but it’s equally essential.

A Certificate of Lawfulness can confirm that your project doesn’t need planning permission because it falls under permitted development. For instance, some minor home alterations such as extensions without planning permission, permitted development outbuildings, or a permitted development rear extension may not necessarily require planning permission, in some instances.

To help you understand if your project falls under lawful development, contact us to discuss your project.

We also assist you in obtaining a Certificate of Lawfulness for your existing use or proposed development.

The Difference Between Lawful Development Certificate and Planning Permission

While both the Certificate of Lawfulness and Planning Permission are significant in the Architectural world, they serve different purposes. A Certificate of Lawfulness is more about confirming that you’re within your rights to proceed with a project under permitted development rules. In contrast, Planning Permission pertains to the approval of a proposed development by your local council.

Why Get a Certificate of Lawfulness?

A Certificate of Lawfulness can provide peace of mind when undergoing construction or renovation projects. But you may ask, “Why do I need a Certificate of Lawfulness, especially if I already have planning permission or my project falls under permitted development rules?”

Legal Assurance

The primary reason to obtain a Certificate of Lawfulness is to have official confirmation that the use of a building or any development is legal. This certification confirms that your project falls under the permitted development extension and is not subject to enforcement action by the local planning authority. For instance, some small extensions may not require planning permission but getting this certificate can protect you from future objections.

The 4-year and 10-year Rules

A Certificate of Lawfulness can also be granted under the 4-year or 10-year rules. The ‘Certificate of Lawfulness 4-year rule’ applies when building work has been fully completed for at least four years. In contrast, the ‘Certificate of Lawfulness 10-year rule’ refers to a situation where a change of use of a building without planning permission has existed for at least ten years.

If you’re looking for more information on how to navigate these rules, our experienced team can provide comprehensive guidance on the Certificate of Lawful Use 10-year rule and the 4-year rule.

Can Neighbours Object to a Certificate of Lawfulness?

Unlike with planning permission, neighbours cannot formally object to an application for a Certificate of Lawfulness. This makes it a good option for developments likely to face objections during the traditional planning application process. But remember, this doesn’t mean you should disregard your neighbours’ concerns; it’s always good practice to maintain open communication with them about your plans.

Types of Certificate of Lawfulness

There are two main types of Certificate of Lawfulness: ‘Existing’ and ‘Proposed’. An ‘Existing’ certificate is used to confirm that an existing use of land or buildings is lawful.

A ‘Proposed’ certificate, on the other hand, is used to confirm that a proposed use or development is lawful.

Proving a Certificate of Lawfulness and Permitted Development

We’ve tackled the differences between planning permission and a certificate of lawfulness, and why you might need the latter. Now, let’s look at how you can prove a certificate of lawfulness and address the issue of planning permission and permitted development.

Proving a Certificate of Lawfulness

Proving a certificate of lawfulness relies on the evidence provided. You must be able to demonstrate beyond reasonable doubt that your development is lawful. This evidence can come in several forms, such as sworn affidavits, dated photographs, invoices for work done, or utility bills. The more comprehensive your evidence, the better your chance of proving your case.

Our team can guide you through the process of gathering and presenting the evidence needed for your certificate of lawfulness application, whether it’s for an existing use or a proposed development.

Planning Permission and Permitted Development

Many homeowners wonder, “Do I need planning permission if I have permitted development?” It’s an important question. Generally, permitted development rights mean you can undertake certain types of work without needing to apply for planning permission. These works can include minor extensions, loft conversions, and some outbuildings.

However, there are limitations and conditions on what you can and cannot do under permitted development rights. This is where it becomes crucial to secure a lawful development certificate, even when your project falls under permitted development.

Whether you are applying for planning permission, building without planning permission, or looking to secure a certificate of lawfulness, our services encompass all these areas. We can guide you through the planning application portal, or assist you in gaining a permitted development certificate.

We hope you’ve gained a better understanding of the difference between planning permission and a certificate of lawfulness, and the significance of both in the Architectural world.
