If you're planning a construction project, you may have heard the terms Building Regulations and Planning Permission used interchangeably. However, they are two separate processes, each serving a different purpose.
Understanding the difference is important before starting any building work, whether you're planning a home extension, converting an existing property or undertaking a commercial development.
So, what is the difference between Building Regulations and Planning Permission, and when might you need both?
What is Planning Permission?
Planning Permission is concerned with how land and buildings are used and developed. It is managed by the Local Planning Authority (LPA), usually through your local council.
The planning process considers how a proposed development will affect its surroundings and whether it is appropriate for the location.
This can include:
The size, scale and appearance of a proposed development.
The use of land and existing buildings.
The impact on neighbouring properties.
Access, parking and highways.
Landscaping and the surrounding environment.
The impact on conservation areas and listed buildings.
For example, if you're planning a large extension, a new residential development or a change of use to an existing building, you may need to obtain Planning Permission before proceeding.
Some projects may fall under permitted development rights, meaning a formal planning application is not required, provided all relevant conditions and limitations are met.
What are Building Regulations?
Building Regulations set the minimum standards that building work must meet to ensure buildings are safe, healthy, accessible and energy efficient.
Unlike Planning Permission, which considers whether a development is appropriate, Building Regulations focus on how the building work is designed and carried out.
They cover a wide range of technical requirements, including:
Structural safety and stability.
Fire safety.
Resistance to moisture and contaminants.
Ventilation.
Drainage and sanitation.
Energy efficiency and conservation of fuel and power.
Access to and use of buildings.
Protection from falls and other safety risks.
Building Regulations can apply to new buildings, extensions, alterations and changes to existing properties.
Depending on the project and the applicable requirements, you may need to obtain Building Regulations approval before work begins.
What is the difference between the two?
Although both processes relate to construction and building work, they assess different aspects of a project.
Put simply:
Planning Permission considers what you can build and how it affects the surrounding area.
Building Regulations consider how the building work must be designed and constructed to meet the required technical standards.
For example, you might receive Planning Permission for a proposed extension, but this does not automatically mean the design and construction details meet Building Regulations.
Equally, having Building Regulations approval does not mean that Planning Permission has been obtained where it is required.
The two processes are separate, and one does not replace the other.
Do I need both Planning Permission and Building Regulations approval?
In many cases, yes. However, the requirements will depend on the type of work being undertaken.
Here are some examples:
Home extensions - A proposed extension may require Planning Permission, although certain extensions can fall under permitted development rights. Building Regulations will also generally apply to the construction of the extension.
Loft conversions - A loft conversion may not require Planning Permission if it meets the relevant permitted development conditions. However, Building Regulations approval will normally be required to address matters such as structural stability, fire safety, insulation and access.
Internal alterations - Some internal alterations may not require Planning Permission, particularly where they do not materially affect the external appearance of a building or involve a material change of use. However, Building Regulations may still apply, particularly where structural work or other regulated building work is involved.
Commercial developments - Commercial projects can involve both planning and Building Regulations considerations. This may include new developments, refurbishments, changes of use and alterations to existing buildings.
The requirements will depend on the nature and scope of the proposed works.
Who deals with Planning Permission and Building Regulations?
Although the processes are separate, there are different organisations responsible for each.
Planning Permission - Planning applications are dealt with by the relevant Local Planning Authority. This is usually your local council's planning department.
Building Regulations - For work that is not subject to the higher-risk building regime, Building Regulations services can be provided through either Local Authority Building Control or a Registered Building Control Approver, depending on the applicable approval route.
A Registered Building Control Approver works with clients and project teams to assess building work against the relevant Building Regulations requirements.
At Delta Building Control, we provide Building Control services for residential and commercial projects, supporting clients throughout the regulatory process.
Why is it important to consider both early?
Understanding the planning and Building Regulations requirements at an early stage can help you prepare for your project more effectively.
Engaging with the relevant professionals during the design and planning stages can help identify potential issues, establish what information may be required and ensure the appropriate processes are considered before construction begins.
It is also important to remember that other permissions or consents may be needed depending on the project. For example, work to a listed building may require Listed Building Consent in addition to any relevant planning and Building Regulations requirements.
Taking the time to establish what applies to your project can help avoid unnecessary complications later on.
How can Delta Building Control help?
At Delta Building Control, we understand that navigating the Building Regulations process can sometimes feel complicated, particularly when you're managing several aspects of a construction project.
As a Registered Building Control Approver, we provide Building Control services across Yorkshire, supporting residential and commercial projects with plan assessments, site inspections and the assessment of building work against the relevant regulatory requirements.
While Planning Permission is dealt with separately by the Local Planning Authority, our team can support you with the Building Control side of your project.
Whether you're planning an extension, a conversion or a larger commercial development, we're here to help make the Building Control process as clear and straightforward as possible.
