Loft Boarding: Where can I board? Is my loft safe?

Your loft, often neglected and overlooked, holds the untapped potential to become a valuable and versatile space in your home. But how do you use it?  Whether you’re converting your loft, looking to increase storage room, or even building your own home from scratch, knowing how to board your loft properly and safely is key. Here we’ll cover everything you need to know including   

Step 1: Assess the Loft 

  1. Check the Joist Strength: Ensure the loft joists are sturdy and at least 100mm in height. If they are not, you may need to reinforce or replace them. 
  2. Evaluate Insulation: Determine the type and depth of insulation in your loft. Ensure it complies with building regulations, and plan to lay chipboard flooring above it without compressing it.

Step 2: Gather Materials and Tools 


  • Flooring-grade chipboard sheets (18mm thickness is recommended) 
  • Loft legs or support brackets 
  • Screws 
  • Tape measure 
  • Saw 
  • Screwdriver or drill 
  • Safety equipment (gloves, goggles, mask)

Step 3: Plan the Layout 

  1. Measure and Mark – Measure the dimensions of your loft and mark the areas you want to board. Consider leaving access areas for maintenance, like over the loft hatch.
  2. Position Loft Legs: If using loft legs, position them evenly across the loft to create a raised platform. This helps maintain insulation effectiveness. 

Step 4: Cut and Install 

  1. Cut Legs to Size: If using loft legs, cut them to the desired height using a saw. 
  2. Install Legs: Attach the loft legs to the joists, ensuring they are evenly spaced and level. This creates a stable base for the chipboard flooring. 

Step 5: Install the Chipboard Flooring 

  1. Cut Chipboard Sheets: Measure and cut the chipboard sheets to fit the marked areas using a saw. 
  2. Lay the First Sheet: Start from one corner and lay the first sheet, ensuring it fits snugly against the walls or loft sides. 
  3. Secure with Screws: Secure the chipboard to the joists using screws. Place screws at regular intervals, ensuring they are driven flush with the surface to avoid tripping hazards. 
  4. Repeat the Process: Continue laying and securing chipboard sheets until the entire boarded area is covered.

Step 6: Finish and Secure 

  1. Fill Gaps: Fill any gaps between the chipboard sheets using the appropriate filler material.
  2. Secure Edges: Secure the edges of the chipboard sheets to prevent movement. You can use additional screws or adhesive. 

Step 7: Safety Checks

  1. Check Stability: Walk across the entire boarded area to ensure stability and identify any squeaks or movement. 
  2. Inspect for Fire Safety: If fire safety is a concern, consider using fire-resistant materials or treatments. 

Step 8: Optional Finishing 

  1. Touches Paint or Seal: Optionally, paint or seal the chipboard to protect it and improve aesthetics. 
  2. Install Lighting: Consider installing lighting fixtures to illuminate the space if needed.
