Timber battens have replaced concrete roof tiles as the hardest-to-obtain construction product, although the overall picture for products and materials is more positive than it has been in recent months.

Overall construction product supply has improved slightly but certain items including bricks and blocks, cement, concrete roof tiles, timber battens, chipboard, steel lintels, and PVC products remain in short supply.

Three out of four contractors are experiencing problems with the supply of materials and products.
