We’ve been working with construction buyers and suppliers for 20 years – we work closely with our partners and have a deep understanding of buyers’ needs. At Constructionline, we pride ourselves on opening up opportunities for members to access a wide range of procurement contracts and projects – and for buyers to access a validated pool of high-quality suppliers.

Compliance is at the heart of what we do. Whether it’s getting to grips with new standards and requirements or updating our systems to enable buyers to search on a wider range of criteria, our longstanding experts keep ahead of changing regulation – and so does our platform.


Not only do we work to enhanced PAS 91 criteria, we can also validate suppliers as ‘Deemed to satisfy’ for SSIP via our health and safety specialists at Acclaim. In using the Constructionline platform, buyers can expect to simplify and speed up their search, validation and purchasing decision processes considerably, improving resource and cost efficiency.
