Almost always, yes. Most lofts can be boarded, although the installation is not always simple. There are restrictions and regulations around what you can and cannot do in your loft.

Can you lay loft boards directly onto your joists?

No. Putting boards directly onto your joists will squash your insulation and restrict airflow in your loft. Not only is this against building regulations, but it can also cause damp and mould to form from restricting the airflow.

Can you board over loft insulation?

Yes, as long as the boarding is raised above your insulation level and has a small gap to allow airflow. Not raising the boarding can cause dampness and mould to form from restricting the airflow.

Do I need permission to board my loft?

You can board out your loft without building consent, but it can only be used for storage or a non-living space, such as a hobby room.

Can I board my loft and use it as a bedroom?

If you're converting your loft into an extra bedroom or a room considered a living space, the work must meet the government's building regulations. The room must be accessible via a permanent staircase and comply with the correct fire regulations. This requires a full loft conversion, which is not a service we offer.

How long does it take to board a loft?

Depending on the size of the area and the ease of access, most loft boarding jobs take between one and two days to install.

Can I board my new build loft?

Absolutely. UK Loft Boarding specialises in boarding out new and old loft spaces. All our work is carried out in accordance with building regulations and does not affect your NHBC new build warranty.

Does boarding your loft void/invalidate NHBC?

No, it will not affect your warranty as long as it is installed correctly. There are several reasons your builder may say otherwise, such as concerns about squashing insulation, roof truss strength, or potential dampness. However, correctly fitting loft boards using one of our raised floor systems will not affect your warranty.

How Much Heat is Lost Through Your Roof?

Up to 25% of a home's heat can be lost through an uninsulated roof. Heat naturally flows from warmer to cooler areas, so if your loft isn't properly insulated, energy escapes quickly—costing you money and comfort.

Proper insulation prevents this loss, improves energy efficiency, and helps your home meet modern standards.
