We are proud to have achieved Gold Membership status with Constructionline. We are confident that we are now in the best situation to navigate the supply chain process in an efficient and reliable way for all of our partnerships.

What are the benefits it can offer you?

With verified membership, we pre-qualify for clients and contracts across the UK, which saves valuable time and money.

Constructionline Gold is so popular because it illustrates to buyers that we have been subjected to increased scrutiny around governance and risk management.

We go above and beyond PAS 91 requirements

A standardised pre-qualification questionnaire developed by the British Standards Institute, PAS 91 is a common minimum requirement for construction procurement. But, with a Gold membership, we go above and beyond PAS 91.

With enhanced validation checks including environmental management, quality management, equal opportunities and diversity, Modern Slavery Act adherence, and anti-bribery and anti-corruption policies, these extra verifications help make sure we really stand out to public and private sector buyers.

We meet the Common Assessment Standard

Developed in partnership with Build UK, the Common Assessment Standard goes one step further than PAS 91. A standardised set of questions crafted from existing systems, such as PAS 91, as well as input from clients, suppliers and trade associations, the Common Assessment Standard helps us save time and money during the pre-qualification process.

Covering areas such as environmental management, Building Information Modelling (BIM), and corporate and social responsibility, the Common Assessment Standard lets buyers know with confidence that we can satisfy all their requirements.

We pre-qualify for some of the UK’s biggest buyers

Gold membership has become the industry standard. Adopted by some of the largest buyers in the UK, brands such as VINCI, the Wates Group, BAM Construction, Kier and Balfour Beatty demand that suppliers meet this membership level.

In fact, for searches that select a specific membership level, over 81% included Gold in the search criteria. This is 64% more than those that selected Silver.

We have gained SSIP accreditation

Constructionline Gold also includes Acclaim’s SSIP accreditation. An umbrella body for assessment schemes, SSIP plays an important role in reducing duplication and cost across the supply chain.

Instead of having to hold multiple health and safety schemes, SSIP provides a single platform for managing compliance and health and safety information, cutting what we would normally spend on a range of different health and safety schemes, by as much as 40%!
