Constructionline Explained: What Bronze, Silver and Gold Actually Check for Subcontractors

If a main contractor has emailed you asking for "Constructionline Gold before we set foot on site", you want Constructionline explained in one sitting — not a brochure. The short version: Constructionline is a pre-qualification platform (part of Once For All) where you answer a question set once, their team verifies your evidence, and buyers see your status. The tiers — Associate, Bronze, Silver, Gold, Platinum — are not quality grades of the same check. They are different question sets, and the jump that actually matters to a small firm is Silver to Gold.

TL;DR

Constructionline has five levels: Associate (free data storage, no verification), then four verified paid tiers — Bronze, Silver, Gold and Platinum. Bronze verifies identity, financials, insurance, health and safety and at least one work category; Silver adds corporate and professional standing; Gold adds environmental, quality, equal opportunities, modern slavery, anti-bribery and Building Safety Act questions, and is the level that delivers the Common Assessment Standard. SSIP is bundled across all paid tiers via Once For All Health & Safety — and per the Constructionline Bronze membership guide you need a valid SSIP certificate to achieve Bronze at all, so the old "Bronze isn't SSIP" line is out of date. Price is set by your turnover band and whether you already hold an SSIP, not by a flat published fee. Pick the tier the contractor who asked actually specifies: paying for Gold when Bronze was requested buys you a bigger annual paperwork job, not more work.

What is Constructionline, and who actually asks for it?

Constructionline is a pre-qualification and supplier-compliance platform used by UK main contractors and public buyers to check a subcontractor's identity, finances, insurance and health and safety before they let you tender. You complete the question set in their portal, upload evidence, their verification team checks it, and your verified status becomes visible to buyers searching for your trade and region. According to the Constructionline Bronze membership guide, an assessment submission can take up to 10 working days to be reviewed.

The people who ask for it are usually naming a specific tier, and that is the single most useful fact in this whole article. Constructionline publishes buyer pages stating the level each contractor requires — some specify Bronze as a minimum, plenty of tier 1 contractors specify Gold. You are not choosing a tier in the abstract; you are matching a requirement someone has already written down.

What do Bronze, Silver and Gold actually verify?

Each Constructionline tier builds on the one below it, and each adds a block of evidence you then have to keep current every year. Bronze covers identity (including full accounts, not the filleted version filed at Companies House), insurances, health and safety, and at least one verified work category. Constructionline's own Silver page describes Silver as everything in Bronze plus verification for corporate and professional standing and health and safety. The Gold and Platinum supplier guide states that Gold is "specifically tailored to meet Common Assessment Standard requirements" and assesses environmental management, quality management, equal opportunities, Modern Slavery Act adherence and anti-bribery and corruption, with SSIP assessed as well.

Is Constructionline Bronze SSIP-approved?

Yes — and more than that, you cannot get Bronze without SSIP. The Constructionline Bronze membership guide states plainly that to achieve Constructionline Bronze you must have a valid SSIP certificate, and that you can apply for SSIP from Once For All Health and Safety at no additional cost. Constructionline's membership pages confirm SSIP is now included across Bronze, Silver, Gold and Platinum, and that if you already hold an SSIP elsewhere you show it through Deemed to Satisfy.

This matters because a lot of older advice online — and a fair few forum posts — still says Bronze "isn't an SSIP". That was true of an earlier structure and is not how the tiers work now. If you already hold CHAS, SMAS Worksafe or Acclaim, you can present that certificate rather than being assessed twice; if you don't, the bundled Once For All assessment is the SSIP. Either way you end up holding a dated SSIP certificate with its own expiry, which is exactly the thing that catches people out. Our guide to what SSIP mutual recognition does not cover sets out the limits of Deem to Satisfy in detail.

Where is the real jump in paperwork between the tiers?

The step from Silver to Gold is where a one-van or twelve-van firm feels the difference, and it is a policy-writing job rather than a safety job. Gold is the level that asks for environmental, quality, equal opportunities, anti-bribery and modern slavery material, plus the Building Safety Act questions. Constructionline's older Gold checklist guidance has required things like a quality policy signed and dated by a director within the last 12 months and an anti-bribery policy signed within the last three years — the sort of technicality that fails a submission even when the underlying practice is sound.

There is one genuine easement worth knowing. The Constructionline Bronze guide sets out exemptions for micro-companies meeting any two of: no more than 10 employees, turnover no more than £1 million, or a balance sheet total no more than £500,000. Build UK likewise states that for companies meeting the micro-business criteria, the Common Assessment Standard's assessment standards are applied in a proportionate way. If you are a six-man firm, you are not being assessed as if you were Kier — but you do have to tell the portal you're a micro-company in the first place.

What does Constructionline cost for a subcontractor?

Constructionline does not publish one flat fee. The sign-up flow asks for your turnover band and whether you currently hold a valid SSIP, and prices the membership from there — so two firms on the same tier pay different amounts. That is why any single figure you read on a third-party site should be treated as indicative. We keep the current bands and what they include in our Constructionline cost breakdown for subcontractors.

Two mechanics are worth knowing before you pick:

1. 1
   Upgrading mid-term is credited. The Bronze membership guide says you can upgrade to Gold at any time from 'Manage Account', with the remaining balance of your previous membership discounted onto the new one. Starting at Bronze is not money burned if a buyer later demands Gold.
2. 2
   The bundled SSIP is the saving. Constructionline markets the included Once For All Health & Safety SSIP as removing the need to pay for a separate health and safety assessment. If you already pay for CHAS or SMAS purely to satisfy SSIP, run the numbers on both before renewing either.

A worked example: asked for Bronze by one contractor, Gold by another

Say a 12-engineer electrical and mechanical firm, turnover around £900,000, holds SMAS Worksafe for SSIP. A facilities client specifies Constructionline Bronze as a minimum. A regional main contractor specifies Gold with the Common Assessment Standard. Buying Bronze satisfies one and not the other; buying Gold satisfies both, because Gold sits above Bronze in the same question set and, per Build UK, delivers CAS desktop certification at the same time.

The honest trade-off is not the fee difference — it's that Gold adds a quality policy, an environmental policy, equal opportunities, anti-bribery, modern slavery and Building Safety Act answers to the list of things you must keep signed, dated and current every single year, forever. If only the facilities client is real work today and the main contractor is a maybe, Bronze now plus a credited upgrade when the job firms up is the cheaper route through the gate. If both are real, go Gold once. For the tier-by-tier decision in more depth, see our Bronze vs Silver vs Gold comparison, and if Gold is where you're heading, the Gold requirements and evidence list.

How does Constructionline renewal actually work?

This is the part nobody warns you about, and it is where most of the pain lives. Constructionline does not give you one tidy annual renewal date. The Bronze membership guide explains that once requirements are verified they carry individual expiry dates — where a requirement contains a licence, it expires with that licence; where it doesn't, it expires a year from the date of verification. An email reminder is sent and the item appears in 'Action Required' 30 days before expiry.

Do the arithmetic a 5am kitchen-table administrator has to do. You get 30 days' notice. An assessment submission can take up to 10 working days to review — call it two weeks. Rejections for the usual technicalities (wrong company name on a certificate, a policy not signed by a director within the last 12 months) send you round again. So a 30-day warning is realistically a fortnight of slack, per requirement, on staggered dates, while your insurance certificate and SSIP certificate run on their own separate clocks. Our guide to tracking accreditation renewal deadlines covers the wider pattern, and the scheme comparison hub puts Constructionline alongside CHAS, SafeContractor and SMAS.

Frequently Asked Questions

Is Constructionline an SSIP scheme in its own right?

Constructionline memberships include an SSIP from Once For All Health & Safety, and Constructionline's membership pages state SSIP is included across Bronze, Silver, Gold and Platinum. If you already hold an SSIP certificate from another scheme, you present it through Deemed to Satisfy rather than being assessed twice.

Do I need Constructionline Gold to get the Common Assessment Standard?

For the desktop level, yes — Build UK's Recognised Assessment Body list names Constructionline Gold as the desktop route and Constructionline Platinum as the site-based route. Bronze and Silver do not deliver the Common Assessment Standard. Other Recognised Assessment Bodies, including Veriforce CHAS and SMAS Worksafe, offer their own routes.

Is Constructionline Associate membership worth having?

Associate is free and lets you store pre-qualification responses and register for Dynamic Purchasing Systems, but it is not a verified membership. If a main contractor has asked for "verified" status or named a tier, Associate will not satisfy them.

How long does Constructionline verification take?

Constructionline's Bronze membership guide states it can take up to 10 working days for a submission assessment to be completed. That is per submission, so a rejection on one requirement can add another cycle — start well before any tender deadline.

Can I upgrade from Bronze to Gold part-way through the year?

Yes. The Bronze membership guide says you can upgrade to Gold at any time via 'Manage Account', with the remaining balance of your existing membership discounted onto the new one. You then have to complete the additional Gold question set and have it verified.

Before your next Constructionline expiry email lands

The awkward truth in this guide is that Constructionline doesn't hand you one renewal date — it hands you a set of requirements with individual expiry dates, 30 days' notice each, and up to 10 working days of assessment queue inside that window, while the same insurance certificate and SSIP certificate also have to be current for whatever other scheme a contractor asks about. TradeComply tracks every accreditation you hold with reminders at 60, 30 and 7 days by email and calendar, and keeps your insurance, RAMS and training records uploaded once and reused for every scheme that asks, with share links so a main contractor gets current certificates without an email chain. Everything above stands whether or not you ever sign up — the tier you need is still the one the contractor named, and Bronze with a credited upgrade is still the cheaper route if Gold is only a maybe.
