Step change innovations are rare in most industries, but the construction products industry has undoubtedly made its contribution over the years. Examples include the introduction of float glass, the development of non-asbestos-based fibres and the development of plastics for hot water systems. However, far more frequently, we progress in an evolutionary way, building on previous innovations to develop products or processes with a wider application, a better performance or easier installation.

In Kate Barker's recent review of housing supply, she said: "Innovation and skills are important factors in determining the industry's ability to increase housing supply. The impact of increasing land supply on output will be severely limited if innovation is low, or there is a shortage of skilled labour." She did, however, recognise the problems inherent in the use of new products and called on the industry to develop a strategy to "address barriers to modern methods of construction".

Product and process innovation can make a significant contribution to addressing the skills shortage facing the industry. However, too many products are still purchased on the basis of lowest initial cost. Such procurement practice acts as a disincentive to manufacturers to innovate in a way that provides greater efficiencies in the construction process.

The culture in the industry must change if it is to take full advantage of the innovative capabilities of manufacturers and suppliers
