Is planning permission needed when laying concrete?

Whether you need planning permission to lay a concrete floor depends on several factors, including the scope and location of your project. Generally, for internal concrete floors within an existing structure, planning permission is not usually required. This includes renovations or upgrades to your home’s interior where you’re replacing or installing a new concrete floor, as it falls under permitted development rights.

However, if you are laying a concrete floor as part of an extension or a new build, you will typically need planning permission. This is because any significant changes to the structure or footprint of your property usually require approval from your local planning authority. The need for planning permission ensures that the proposed construction meets local building codes and zoning regulations, maintaining the safety and aesthetic harmony of the community.

For external concrete floors, such as driveways, patios, or any other hardstanding areas, planning permission might be necessary if the project covers a substantial area or impacts the drainage system. For example, if your concrete floor exceeds the allowed size or alters the natural drainage, you will need to consult with the planning authority. Moreover, properties in conservation areas or listed buildings might have stricter regulations, necessitating permission even for minor changes

Other building regulations for concrete flooring to be aware of

  • Structural integrity
    The concrete floor must be designed to support the intended loads. This includes both live loads (people, furniture) and dead loads (the weight of the concrete itself). Ensuring structural integrity may require consultation with a structural engineer.
  • Thermal insulation
    Adequate insulation must be installed to meet energy efficiency standards. This helps reduce heat loss and improve the thermal performance of the building. The type and thickness of insulation material must comply with local building codes.
  • Damp proofing
    A damp proof membrane (DPM) must be installed to prevent moisture from rising through the concrete floor. This is crucial to prevent damp problems that can lead to mold and structural damage.
  • Ventilation
    Proper ventilation is necessary to prevent moisture buildup and ensure good air quality, especially in spaces like basements. Ventilation requirements will vary based on the specific application and local regulations.
  • Expansion joints
    Expansion joints may be required to allow for thermal expansion and contraction of the concrete, preventing cracks and structural damage.

Impact on drainage

Laying concrete can significantly impact the drainage of the area, as it creates an impermeable surface that prevents water from naturally soaking into the ground. This alteration in the natural water flow can lead to waterlogging or flooding, especially in heavy rain conditions. As a result, managing water runoff is needed to prevent these issues and protect both the new concrete surface and the surrounding areas from potential water damage.

When a project involves significant impermeable surfaces, planning permission might be required to ensure proper drainage solutions are in place. Local authorities often mandate the inclusion of detailed drainage plans in the planning application. These plans should demonstrate how surface water will be effectively managed to avoid adverse effects on the property and adjacent land.

Sustainable Drainage Systems (SuDS) are increasingly being required by local authorities as part of these drainage plans. SuDS are designed to manage surface water in a more sustainable manner, mimicking natural processes to reduce runoff volumes and rates.

Neighbouring properties consideration

When laying a new concrete floor you'll have to evaluate how the changes might impact the privacy, light, or view of adjacent properties. Any modifications that alter the existing conditions can lead to disputes or objections from neighbours, potentially delaying or complicating the project.

Privacy is a major concern, particularly in residential areas where the proximity of homes means that changes can easily affect neighbors. For instance, if the new concrete floor involves raising the ground level, it could lead to overlooking issues, reducing the privacy of adjacent properties.

Similarly, the new concrete floor's effect on light is an important factor. If the project involves constructing additional structures or features that cast shadows on neighboring properties, it can reduce the amount of natural light they receive. This is especially pertinent for projects that include retaining walls, elevated platforms, or extensions. Local planning authorities typically consider the "right to light" in their assessments.

The view from neighboring properties can also be impacted by your concrete flooring project. While there is generally no legal right to a view, significant alterations that obstruct previously open views can lead to objections.
