What Do I Not Need Planning Permission For?

Planning permissions can often be a confusing maze for homeowners looking to improve their properties. However, not every project requires you to apply for planning permission. Some works fall under what’s called “permitted development.” So, what do you not need planning permission for? Let’s break it down.

Understanding Permitted Development Rights

Permitted development rights allow you to carry out certain alterations without having to go through the hassle of a formal planning application. These rights apply mostly to smaller projects, particularly those that don’t have a major impact on the look or function of your property. The idea is to give homeowners the freedom to make their home more suitable to their needs without waiting for council approval. But what types of work are covered?

Common Projects That Don’t Need Planning Permission

1. Small Extensions and Conservatories

If your extension falls within specific size limits, you may be covered under permitted development rights. Single-storey rear extensions, for example, can extend up to 3 metres for an attached house or 4 metres for a detached house. Conservatories also often fall within these limits, meaning you won’t need planning permission, though it’s always wise to double-check the rules that apply in your area.

2. Loft Conversions

Loft conversions are an excellent way to increase living space without extending the footprint of your home. As long as you stay within specific volume limits (40 cubic metres for terraced houses, 50 cubic metres for detached or semi-detached homes), and you don’t exceed the current roof height, your loft conversion will generally not need planning permission.

3. Internal Alterations

Planning permission is usually not needed for internal changes, such as knocking down non-load-bearing walls, adding a new kitchen or bathroom, or converting a bedroom. These changes do not impact the external appearance of your property and, therefore, do not typically need council approval.

4. Sheds, Outbuildings, and Garden Rooms

Building a shed or an outbuilding in your garden generally doesn’t require planning permission, provided the structure meets certain criteria: it must be a single storey, take up no more than half the garden, and not exceed a height of 2.5 metres for a structure within 2 metres of a boundary.

5. Solar Panels

Eco-friendly additions, like solar panels, can often be installed without the need for planning permission. However, the installation should not protrude more than 200mm from the wall or roof slope, and there might be some restrictions if you live in a conservation area.

Limitations of Permitted Development

While the above projects generally don’t need planning permission, it’s important to note there are some exceptions. For instance, if you live in a conservation area, national park, or an Area of Outstanding Natural Beauty (AONB), your permitted development rights might be more restricted. Flats and maisonettes also have different rules, so it’s essential to check the specific regulations that apply to your property type.

Always Double-Check Before You Build

It’s always advisable to check with your local planning authority if you’re unsure whether your project needs permission. Regulations can vary, and the last thing you want is to be told to undo work you’ve already done. When in doubt, consult an expert—getting it right the first time can save a lot of stress and expense down the road.

Why Might Planning Permission Be Refused?

Even if you do apply, it’s possible that planning permission might be refused. Reasons include:

Impact on Neighbours: The proposed work may negatively impact neighbours through loss of light, overshadowing, or blocking views.
Aesthetics: If the planned changes are out of character for the local area, the council may deny permission. For instance, building a modern, glass extension in an area with traditional, brick-clad homes could be a reason for refusal.
Environmental Concerns: In some cases, planning permission may be denied due to environmental impacts, such as harm to nearby wildlife or natural habitats.
