Constructionline registration, particularly achieving Gold or Platinum membership, can appear complex and demanding. At EmmersonWills, we specialise in simplifying the entire process, making construction sector access straightforward for businesses of all sizes.
What is Constructionline?
Constructionline is the UK’s largest register of pre-qualified contractors, consultants, and suppliers for the construction industry. With over 45,000 registered suppliers accessible to more than 10,000 buyers (including central government departments, local authorities, and major contractors), Constructionline has become essential for businesses seeking construction sector opportunities.
The platform manages the prequalification process on behalf of buyers, validating members against standardised criteria including the Common Assessment Standard (which replaced PAS 91). Once registered and verified, suppliers avoid repetitive prequalification for each tender, saving significant time and administrative costs whilst demonstrating credibility to potential clients.
Constructionline membership provides a single route to market across public and private sector construction projects, making supplier details immediately available to procurement professionals seeking qualified contractors for their projects.
Why Does Your Business Need Constructionline?
Many public and private sector buyers require Constructionline registration before considering suppliers for tender opportunities. Without registration, businesses may be excluded from contracts regardless of their capabilities or track record.
The construction procurement process traditionally involved completing separate, lengthy prequalification questionnaires for each contract opportunity. Constructionline eliminates this repetition by providing verified, searchable supplier profiles that buyers can access when sourcing contractors. This significantly reduces the administrative burden of tendering whilst improving visibility to potential clients.
Major tier 1 contractors and public sector organisations use Constructionline as their primary supplier selection platform. Registration demonstrates that your business has undergone independent verification of key compliance areas including health and safety, financial standing, environmental management, quality systems, and professional capability.
The platform also provides access to Marketplace, which publishes tender opportunities and project leads, helping businesses identify and pursue relevant contracts proactively rather than relying solely on existing client relationships.
Constructionline Membership Levels
Constructionline offers different membership tiers designed to meet varying business needs and buyer requirements:
Associate Membership
Free entry-level access providing basic data storage and platform familiarisation. Associate members can store prequalification responses and register for Dynamic Purchasing Systems (DPS). This tier acts as "try before you buy" for businesses exploring the platform.
Bronze Membership
Entry-level verified membership covering basic compliance requirements including fundamental health and safety and financial checks. Bronze suits smaller contractors working on less complex projects.
Silver Membership
Intermediate verification requiring more detailed assessment of operational systems and processes. Silver membership meets Safety Schemes in Procurement (SSIP) core criteria.
Gold Membership
The most popular tier, meeting the Common Assessment Standard (CAS), the construction industry's preferred prequalification standard. Gold demonstrates compliance with enhanced requirements including environmental management, quality management, equality and diversity, and Building Information Modelling (BIM) capability. Many major contractors now require Gold membership as a minimum for consideration.
Platinum Membership
The highest tier, incorporating on-site audit verification alongside the desktop assessment included in Gold. Platinum suits larger contractors or those pursuing high-value, complex projects requiring comprehensive supply chain assurance including physical site inspection.
All verified memberships (Bronze through Platinum) include SSIP accreditation from Once For All Health & Safety as standard.
Understanding the Common Assessment Standard
The Common Assessment Standard (CAS) replaced PAS 91 following its withdrawal by the British Standards Institution in 2023. Developed by Build UK with industry experts, CAS has become the construction industry’s gold standard for prequalification, comprising a standardised set of questions covering health and safety, environmental management, quality management, equality and diversity, BIM, corporate social responsibility, and Building Safety Act compliance.
CAS enables businesses to complete one comprehensive assessment annually that qualifies them for a wide range of contracts. There is a data sharing agreement between the three recognised CAS assessment bodies (CHAS, Achilles, and Constructionline), meaning companies assessed by any recognised body can demonstrate compliance across all platforms.
Constructionline Gold members automatically meet the desktop CAS requirements, whilst Platinum members satisfy the on-site audit standard. Major UK principal contractors now request or require suppliers to meet CAS requirements, making Gold membership increasingly essential for accessing significant contract opportunities.
The assessment process is thorough but predictable. With proper preparation and support, what initially appears demanding becomes manageable, allowing businesses to demonstrate genuine capability without navigating unnecessary complexity.

Constructionline Frequently Asked Questions
What is the Common Assessment Standard?
The Common Assessment Standard (CAS) is the construction industry’s preferred prequalification standard, replacing PAS 91 in 2023. Developed by Build UK with industry experts, CAS comprises standardised questions covering health and safety, environmental management, quality management, equality and diversity, BIM, corporate social responsibility, and Building Safety Act compliance. Constructionline Gold membership meets the desktop CAS requirements.
How much does Constructionline membership cost?
Constructionline membership fees are based on company annual turnover and vary by membership tier. Associate membership is free. Bronze, Silver, Gold, and Platinum tiers have annual subscription fees ranging from a few hundred pounds for smaller businesses to several thousand for larger organisations. Exact pricing is available on the Constructionline website based on your specific turnover band.
Which Constructionline membership level do I need?
The appropriate level depends on buyer requirements and the types of contracts you pursue. Bronze suits basic compliance needs. Silver meets SSIP requirements. Gold is the most popular tier, meeting Common Assessment Standard requirements that many major contractors now require or prefer. Platinum includes on-site audit for high-value or complex projects. We help businesses determine the most appropriate level for their circumstances.
How long does Constructionline registration take?
Timeline varies by membership tier and your starting position. Associate and Bronze registration can be completed relatively quickly. Silver typically takes 2-4 weeks. Gold and Platinum require more comprehensive information and verification, typically taking 4-8 weeks depending on your readiness. Organisations developing management systems from scratch require additional time for system development before registration.
Do I need ISO certification for Constructionline Gold?
Constructionline Gold requires evidence of management systems meeting ISO 45001, ISO 14001, and ISO 9001 requirements. You don’t need formal ISO certification, but you must have documented systems that satisfy these standards. Many businesses achieve Constructionline Gold without separate ISO certification by developing appropriate systems specifically for Common Assessment Standard compliance.
What documentation does Constructionline require?
Required documentation varies by membership tier. Higher tiers (Gold and Platinum) require policies, procedures, risk assessments, training records, insurance certificates, financial information, health and safety documentation, environmental management records, quality procedures, and evidence of legal compliance. We help organisations gather and present required documentation efficiently.
How long is Constructionline membership valid?
Constructionline membership operates on annual subscription basis. Members must renew annually and keep information current throughout the membership period. Annual renewal involves updating company information, confirming continued compliance, and paying the subscription fee. Verification for higher tiers may be refreshed during renewal.
Can small businesses benefit from Constructionline?
Yes, Constructionline is valuable for businesses of all sizes. The platform enables buyers to search by company size, ensuring small local contractors remain visible to buyers seeking community investment and local supply chains. Bronze and Silver tiers provide accessible entry points for smaller businesses, with options to upgrade as the business grows.
What happens if we fail Constructionline verification?
Constructionline verification identifies gaps or issues in submitted information. Minor issues can typically be addressed by providing additional evidence or clarification. Significant gaps may require system development or documentation improvement before re-submission. With proper preparation, most organisations achieve successful verification first time. Our systematic preparation approach minimises risk of verification failure.
Will Constructionline guarantee us construction contracts?
Constructionline membership provides essential market access and visibility but doesn’t guarantee contract awards. Buyers select suppliers based on capability, capacity, pricing, and suitability for specific requirements. However, without Constructionline registration, many opportunities are completely inaccessible, making membership a prerequisite for competing rather than a guarantee of success.
How does Constructionline relate to other prequalification schemes?
Constructionline is the largest construction sector prequalification platform in the UK. Other schemes exist for specific sectors (UVDB for utilities, sector-specific databases). The Common Assessment Standard has data sharing between three recognised bodies (CHAS, Achilles, Constructionline), meaning CAS accreditation through any provider is recognised across all three platforms.
What is SSIP and how does it relate to Constructionline?
Safety Schemes in Procurement (SSIP) provides health and safety prequalification. All verified Constructionline memberships (Bronze through Platinum) include SSIP accreditation from Once For All Health & Safety as standard. This integrated approach eliminates the need for separate SSIP applications, saving time and costs.
Can we upgrade our Constructionline membership?
Yes, members can upgrade at any time through their account management portal. Upgrading involves completing additional verification requirements for the higher tier and paying the price difference. Many businesses start at lower tiers and upgrade as their business grows or buyer requirements change. We provide guidance on optimal upgrade timing and preparation.
What is Marketplace and how does it help win work?
Marketplace is Constructionline’s tender opportunity platform, publishing over £100 billion of projects annually. It provides access to publicly advertised contracts and unique opportunities from Constructionline buyers. Premium Leads delivers targeted opportunities matching your capabilities and location directly to you, helping identify relevant contracts proactively.
How does Building Safety Act compliance fit into Constructionline?
The Building Safety Act introduced new requirements for construction projects. Common Assessment Standard (achieved through Gold and Platinum membership) includes Building Safety Act compliance assessment. This demonstrates your understanding and capability to meet the Act’s requirements, which is increasingly important for buyers selecting suppliers for relevant projects.
What are the most common Constructionline verification issues?
Common issues include incomplete documentation, insufficient evidence of management systems, gaps in policy coverage, inadequate training records, missing insurance documents, and inconsistencies between questionnaire responses and supporting evidence. Proper preparation addressing these areas significantly increases first-time verification success. Our systematic approach ensures comprehensive readiness.
