Stud partition walls are a relatively easy project, but that doesn’t mean they should be taken lightly. As with any build, certain standards must be met.
Whether you want to create a timber or steel stud partition wall, we’ve pulled together some of the key regulations you need to consider when planning your project.
Do Stud Walls Need Building Regulations Approval?
Generally, you do not need building regulations approval to construct a non-load-bearing stud partition wall. If you are creating a wall that will support the building, you’ll likely need approval.
Some listed buildings require building regulations approval for any work internally or externally, so you may require approval here. There are also other instances when a stud wall might need approval, such as:
- If it forms part of an extension.
- If it changes the purpose of the building, such as turning a home into a business.
For general home improvements, approval is not required for a stud wall. However, some minimum standards must be met whenever building a stud wall, which we go through below.
Stud Wall Thickness Regulations UK
UK regulations allow for wiggle room when it comes to thickness so that stud walls can be suited to any space. However, there are minimum standards to ensure walls have enough strength.
The most common thicknesses for the timbers in a timber-frame partition wall are:
- 100mm x 50mm
- 75mm x 50mm
- Custom thicknesses can also be considered. If building a metal stud wall, you may be able to create a thinner wall.
Remember to consider the thickness of your plasterboard when working out a total thickness for your wall. Also, consider the need for certain insulations and soundproofing before making your wall too thin - we cover these further below.
Stud Wall Spacing Regulations UK
Stud spacing regulations are tied to the thickness of your plasterboard.
NHBC (2011) state that stud wall spacing should be:
- not more than 450mm spacing for 9.5mm boards
- not more than 600mm spacing for 10mm to 20mm boards
Do Stud Walls Have 400 or 600 Centres?
The spacing between studs in a stud wall depends on various factors, such as the building codes and standards, the load-bearing capacity of the wall, the size and spacing of the framing members, and the type of materials used.
In some regions, the standard spacing between studs in residential construction is 16 inches or 400 millimetres on centre, which is often called "400 centres." In other regions, the spacing may be 24 inches or 600 millimetres on centre, referred to as "600 centres."
Therefore, whether a stud wall has 400 or 600 centres depends on the specific building code and construction standards in the area where the wall is being built.
Do Stud Walls Have 400 or 600 Centres in the UK?
In the UK, the spacing between studs in a stud wall is typically 400 millimetres on centre, which is referred to as "400 centres." This spacing is in line with the building regulations and standards in the UK, which specify the minimum spacing requirements for timber studs in walls.
However, it's worth noting that the spacing may vary depending on the specific construction project, as the requirements may differ based on the load-bearing capacity and the types of materials used in the wall construction. It's always best to consult with a professional builder or structural engineer for specific information on stud wall spacing for a particular project.
Stud Wall Fire Regulations UK
One of the most important things to consider whenever building a new wall is fire regulations. Various rules concern the slowing and stopping of fire, depending on your wall’s location in the property.
The main things to consider, particularly if creating a new room, include:
- Fire detection.
- Isolating a fire inside a room.
- A means of escape in an emergency (such as a window).
Planning Portal provides more in-depth information on the subject, which we would urge you to consider.
Due to these regulations, many stud walls will be fitted with relevant fire protection, either in specialist plasterboard or insulation.
Other Stud Wall Building Regulations
You will need to consider a few other standards for your stud wall, depending on its location and purpose.
Sound Insulation
There are minimum requirements for sound insulation if your stud wall is separating a bedroom or bathroom. The best way to provide acoustic protection is often through either specialist plasterboard or insulation.
Ventilation
If you are building a new room, you should ensure that it is adequately ventilated. Bathrooms or kitchens may require mechanical ventilation.
Structural Support
Non-load bearing walls may still need to provide some support if they’re located in key areas of the building, such as parallel to floor joists.
As always, if you’re unsure about the required regulations for your job, speak to the architect or structural engineer running the project as they should be able to advise.
