Loft boarding cost
Whether you’re looking at loft boarding prices to make your attic a usable space, or you’re looking to add value to your property, this loft boarding cost guide will help you budget for your project.

What are loft boards?
Loft boards can be added to an attic to create more floor space and provide an extra barrier to stop heat from escaping.
Loft boards are fitted by laying and securing them to the existing boards on the attic joists. To maximise heat retention, you can also add loft insulation. However, if the boards touch the insulation, they lose their effectiveness, so they need to be fitted high enough.
We recommend hiring a professional for the best results.

Standard loft boarding involves simply laying chipboard flooring directly on top of the existing ceiling joists, assuming they are adequate to take the additional load. You can expect to pay £70 per m² on average for this form of loft boarding.
A more sophisticated raised system raises the boarding above the ceiling joists. This is the ideal solution to allow air circulation beneath the boards, reducing the risk of condensation and damp. On average, you'll pay £1,050 for a 15m² loft space, with the price rising as the m² rises.
