What is Constructionline? Membership tiers, cost and how it differs from CHAS

Constructionline is a UK supplier prequalification service used by construction buyers and contractors. A supplier creates a profile, selects a membership level and submits evidence for the checks included at that level. Buyers can use the resulting profile when deciding which suppliers to consider for work. Constructionline also offers a marketplace for opportunities. Its current subcontractor membership page sets out the options.

If a tender says “Constructionline Gold required”, the question is more specific than “Do you have a health and safety certificate?” Gold includes a broader set of supplier checks and alignment with the Common Assessment Standard. If the tender asks only for an SSIP health and safety assessment, the buyer may accept a current certificate from another SSIP member scheme. The wording of the actual tender determines what you need to show. Do not pay for a membership solely because another contractor in your trade has one.

This guide explains the current tiers, what affects cost, how Constructionline relates to CHAS, and what to check before applying. It deals with supplier prequalification rather than guaranteeing approval for any particular project.

What does Constructionline assess?

Constructionline gathers information that buyers may ask for before putting a supplier on a tender list. The scope depends on membership level. Its tier comparison lists areas such as identity, finances, insurance, professional standing, health and safety, work categories and other organisational information. Gold is shown as meeting the Common Assessment Standard, while Platinum adds a premises audit.

That is different from checking whether a particular team can carry out a particular job safely. A verified company profile is useful procurement evidence. The buyer still needs to assess the actual work, people, competence, site conditions and arrangements. SSIP's supplier guidance likewise describes its health and safety assessment as a prequalification step, with project-specific checks still needed.

Before applying, ask the buyer exactly what they mean by “Constructionline approved”. They may require a named tier, a current SSIP status, a particular trade category, a verified profile, or evidence against a framework's own questions. Those are different requirements. A company can spend money on the wrong level if it treats them as the same thing.

Constructionline tiers at a glance

The current supplier membership options show an Associate entry route alongside Bronze, Silver, Gold and Platinum. Tier features can change, so use the provider's live comparison before buying.

The current offer differs from older articles that describe Bronze as merely a basic listing or say that SSIP begins only at Gold. Constructionline presently lists its renamed Once For All Health & Safety SSIP component in Bronze, Silver, Gold and Platinum. Its separate rebrand notice explains that the former Acclaim SSIP name changed. Check the exact inclusions and your existing SSIP status when obtaining a quote.

Bronze or Silver?

Bronze may be enough where the buyer's requirement is a verified supplier profile and the listed insurance and SSIP information. Silver adds a wider professional-standing layer. The decision should come from the tender documents, the buyer's supplier portal or a direct answer from the procurement team. A broader tier is not automatically the better purchase for a small subcontractor whose clients do not request it.

When is Gold relevant?

Constructionline states that Gold meets the Common Assessment Standard. CAS is an industry prequalification framework rather than a statement that every job, operative and method is approved. Gold can be relevant when a buyer or framework explicitly asks for it. If your buyer uses CAS but accepts another recognised assessment provider, confirm the permitted evidence before assuming Constructionline is the only route.

What does Platinum add?

Constructionline's current plan describes Platinum as Gold plus a one-day premises audit. That is a material difference from a desktop-only choice. Ask whether the buyer actually requires site-based assessment and what locations, business activities and audit scope are relevant. The published plan does not by itself tell you that every project needs Platinum.

How much does Constructionline cost?

There is no reliable single price for every supplier. The provider's current membership price selector asks for a turnover band and whether the supplier already holds valid SSIP certification before showing plan prices. It also says displayed prices exclude VAT. Your chosen tier and circumstances affect the quote.

For an accurate budget, obtain the provider's live quote for your actual turnover band and SSIP status. Then check:

1. Which membership level the buyer requires. 2. Whether the quote includes the relevant SSIP assessment or recognition of your existing certificate. 3. Any joining, upgrade, renewal or additional-service charges shown in the terms. 4. Whether the quote is before or after VAT. 5. What happens if you need another work category or change the legal entity on the profile.

Do not rely on a fixed fee copied from a comparison article. Tier structure, package contents and pricing can change. A published “from” price may also reflect a different turnover band or a supplier that already has SSIP. The cost question is answered by a current like-for-like quote, not a guess.

The useful comparison is cost against a real opportunity. If a named buyer requires Gold for a framework you can credibly bid for, the membership may be commercially necessary. If none of your customers asks for Constructionline, another prequalification route may fit better. A membership alone does not win a contract.

Constructionline vs CHAS: what is the difference?

Constructionline is a broader supplier prequalification and marketplace service with multiple membership tiers. CHAS is a supplier assessment scheme whose health and safety offer sits within the SSIP system. A buyer's request for a specific Constructionline tier can involve corporate, insurance, financial and Common Assessment Standard information beyond the SSIP health and safety core. A valid CHAS certificate does not automatically create a Constructionline Gold profile.

Conversely, a buyer asking only for an SSIP health and safety assessment may not need you to buy both. SSIP's Deem to Satisfy guidance explains how a current assessment from one member scheme can be recognised by another. The route may still involve checks on scope, scheme category and additional information. It does not substitute for any wider buyer requirements.

That gives you a simple decision order:

1. Read the buyer's exact wording and identify whether it asks for SSIP, Constructionline, a CAS assessment, or several different things. 2. Check what you already hold, including the scope and expiry of any SSIP certificate. 3. Ask the buyer whether an existing member-scheme approval and Deem to Satisfy route are accepted for the health and safety element. 4. Obtain a Constructionline quote only for the tier that fits the remaining requirement. 5. Keep the underlying evidence ready for project-specific checks even after a prequalification assessment is complete.

For the wider framework behind those schemes, see SSIP's explanation of mutual recognition. This page explains Constructionline itself.

Is Constructionline legally required?

Constructionline membership is generally a buyer or tender condition, not a universal licence that every UK contractor must buy. A particular buyer can set a supplier-prequalification requirement for a particular procurement. The practical question is whether the buyer will accept your evidence, not whether the scheme name appears in general health and safety law.

Do not confuse a procurement badge with your underlying duties. Contractors and clients still need suitable arrangements for the work, including relevant competence and risk controls. A buyer should not treat a certificate as proof that a named operative can perform a high-risk task on tomorrow's site. A contractor should not represent membership as a guarantee that its methods comply with every legal requirement.

What should you prepare before applying?

Start with the current tier checklist from Constructionline and your buyer's own questions. Gather evidence in the legal entity name that will tender. Check that work categories accurately describe what the business does and that insurance covers the activities and limits requested. If you already hold an SSIP certificate, confirm its status and scope before selecting the price option.

Review documents that tend to become stale: insurance schedules, policies, training and competence records, licences where applicable, and contact details. Make sure the person responsible for the profile can answer assessor questions and update expired information. For Gold or Platinum, follow the provider's current CAS and audit instructions rather than an old application checklist found in search.

A useful internal file has four parts: the buyer requirement, the evidence submitted, the outcome or outstanding assessor query, and the renewal or recheck date. Keep the source document as well as a note saying “approved”. That makes it easier to answer a later procurement question without assuming the badge covers a new scope of work.

How should a buyer use a Constructionline profile?

The membership is an input to supplier selection. A buyer can check that the company profile matches the contractor being appointed, the membership is current, the work categories are relevant and the required tier is verified. Then it should examine the work-specific evidence it needs. The SSIP supplier guidance is clear that prequalification does not finish project-specific assessment.

For example, a scaffolding appointment may call for evidence about the people, design, inspection arrangements and site-specific method. A Constructionline certificate does not answer those questions merely because it is current. Similarly, insurance needs to fit the proposed activity and contract, not simply appear in a supplier profile.

If you are building a repeatable supplier process, ask any software vendor to demonstrate its current evidence collection, review and renewal workflow against a real contractor. This guide does not claim that Complys awards Constructionline status, validates an SSIP certificate or guarantees procurement acceptance.

The decision in one minute

Ask the buyer for the exact tier and evidence required. If the requirement is only an SSIP assessment, check whether your existing member-scheme approval can be recognised. If the buyer requests Constructionline Gold or Platinum, examine the broader CAS and audit requirements rather than assuming a CHAS certificate is enough. Use Constructionline's current tier comparison and price selector for the purchase decision. Then keep the supplier evidence and the project-specific checks current.

The fastest way to waste money is to buy several overlapping badges without checking your buyer's actual requirement. The fastest way to create false assurance is to treat any badge as a substitute for checking the work itself.
