How to Board a Loft : Panels, Boards & Flooring

How to Board a Loft : Panels, Boards & Flooring

Nancy Elansary |

If you're looking to maximise your home's storage space or prepare your loft for a new boiler installation, boarding your loft is a smart and practical solution. In this guide, we’ll walk you through everything you need to know about how to board a loft, including choosing the right loft panels, installing loft boards, and understanding why loft flooring is essential- especially when fitting a boiler in the loft.

Why Board Your Loft?

Boarding your loft transforms an otherwise unused space into a functional storage area. But beyond storage, there are several key reasons to install loft flooring:

  • Safety: Prevents accidents by providing a stable walking surface.
  • Insulation Protection: Keeps insulation intact and effective.
  • Boiler Access: If you're installing a boiler in the loft, boarding is essential for safe and easy access for maintenance and servicing.

How to Board a Loft: Step-by-Step

1. Plan Your Layout

Before you start, measure your loft space and plan where you’ll place your loft panels. Consider access points, lighting, and any obstructions like water tanks or wiring.

2. Choose the Right Loft Boards

Opt for tongue-and-groove loft boards for a secure fit. Standard sizes are typically 18mm thick and come in 1.2m x 0.32m panels. These are ideal for creating a strong and stable loft flooring base.

Looking for high-quality loft panels and accessories?
At The Underfloor Heating Store, we offer a range of durable and easy-to-install loft boards, loft legs, and insulation-friendly solutions—perfect for any DIY loft boarding project.

3. Prepare the Loft

Clear out any debris and ensure your insulation is properly installed. If your insulation is thicker than the joists, consider using loft legs to raise the boards above the insulation level.

4. Install Loft Panels

Here’s how to fit loft panels:

  • Start at the loft hatch and work your way out.
  • Lay the first board across the joists and screw it down securely.
  • Continue placing boards, ensuring each one is tightly joined to the next.
  • Use a jigsaw to cut boards to fit around obstacles.

5. Finishing Touches

Once all loft boards are installed, check for any loose edges and secure them. You can also add a loft ladder and lighting to make the space more accessible and user-friendly.

Installing a Boiler in the Loft? Here’s Why You Must Board It

When fitting a boiler in the loft, boarding is not just a convenience—it’s a requirement. Here’s why:

  • Safe Access: Engineers need a stable surface to work on.
  • Regulatory Compliance: Building regulations often require safe access routes and working platforms for loft-installed boilers.
  • Maintenance: Regular servicing is easier and safer with proper loft flooring in place.

Whether you're creating extra storage or preparing for a boiler installation, knowing how to board a loft is a valuable skill. With the right loft panels, secure loft boards, and a solid loft flooring plan, you can transform your attic into a safe, accessible, and functional space.
