Constructionline Explained: Bronze, Silver, Gold and What Subcontractors Actually Need

If a main contractor or a council has told you to "get on Constructionline", you've probably already found the sign-up page, picked a turnover band, and been shown four coloured badges with no plain-English explanation of which one gets you through the gate. This guide is Constructionline explained from the subcontractor's side of the table: what it is, what each level actually verifies, what it costs, and the one decision that genuinely matters.

TL;DR

Constructionline is a supplier pre-qualification database, not a health and safety scheme — buyers search it to shortlist contractors, and your membership level tells them how much of your paperwork has been checked. There are four paid, verified levels (Bronze, Silver, Gold, Platinum) plus a free, unverified Associate account, and according to Constructionline's own supplier FAQs, annual membership starts from £399 a year plus a one-off joining fee, both scaled to your turnover band. SSIP certification through Once For All Health & Safety is now included across Bronze, Silver, Gold and Platinum, so the old "which tier gets me SSIP" question is dead. The only decision that really matters is whether your client needs you to meet the Common Assessment Standard — that's Gold (desktop) or Platinum (site audit), and nothing below it. Everything else is noise.

What is Constructionline and who actually uses it?

Constructionline is a UK construction and FM supplier pre-qualification platform, now part of the Once For All group. Subcontractors pay an annual membership to have their company data collected, verified and stored in one place; buyers — main contractors, councils, housing associations, FM providers — search that database to build shortlists and to satisfy themselves that a supplier has been checked before an enquiry goes out.

The scale matters when you're deciding whether it's worth the money. Constructionline's supplier FAQs state that approximately 70,000 suppliers have registered and around 10,000 buyers from 3,800 organisations have access to the database, with over 93% of verified suppliers renewing each year. The same page notes that 20% of its contractor members have a turnover under £250,000 — so it is not a big-firms-only club.

What are the Constructionline membership levels?

There are five levels in total: one free and unverified, four paid and verified. Each paid level is cumulative — Silver contains Bronze, Gold contains Silver, Platinum contains Gold.

Does Constructionline include SSIP?

Yes — and this is the single most out-of-date thing on the internet about Constructionline. Constructionline states that SSIP is now included across Bronze, Silver, Gold and Platinum memberships, delivered by its in-house SSIP member scheme, Once For All Health & Safety (the scheme formerly branded Acclaim). If you already hold an SSIP certificate from another member scheme — CHAS, SMAS, SafeContractor and so on — you can show it through the Deem to Satisfy route instead of being reassessed. (Constructionline SSIP page)

Practically, that kills two bits of received wisdom. First, you no longer buy a higher tier just to pick up an SSIP badge. Second, if a main contractor asks for "Constructionline and SSIP", one paid membership can cover both — but only if you actually complete the health and safety assessment or push your existing certificate through Deem to Satisfy. It does not happen automatically because you paid.

If you're new to how the mutual recognition side works, start with SSIP mutual recognition explained, then read what SSIP mutual recognition does not cover — because the Constructionline Gold tier is squarely in that second category.

Do I actually need Constructionline Gold?

This is the only real fork in the road, and it has nothing to do with how big or professional you look. Constructionline confirms that the Common Assessment Standard desktop certification corresponds to Gold, and the site-based audit version to Platinum. Silver members answer some CAS questions so that upgrading later is smoother, but Silver does not certify you to the standard.

Why that matters: the Common Assessment Standard is the industry-agreed PQQ question set developed by Build UK, and it replaced PAS 91 after BSI withdrew that standard. Constructionline's own CAS page states that Procurement Policy Note 03/24 made the Common Assessment Standard the preferred pre-qualification approach for public sector construction procurement above £5.337 million. Plenty of main contractors have since adopted it as their supply-chain minimum regardless of project value. (Constructionline: Common Assessment Standard)

So the test is not "am I a Gold sort of firm". The test is: has the client asked for the Common Assessment Standard, or named Gold specifically? If yes, Bronze and Silver are wasted money. If no — if they just want to see you on the database with valid insurances and an SSIP — Bronze or Silver does the job.

How much does Constructionline cost?

Constructionline prices by turnover band, and the sign-up page asks for your band before it shows a figure — which is why you won't find a clean public price table anywhere. What the supplier FAQs do state plainly: annual membership starts from as little as £399 a year, there is a one-off joining fee for new members based on your turnover band, and from year two onwards you pay the annual fee only. Prices exclude VAT.

TODO(verify): the exact joining fee and annual fee for each of the fifteen turnover bands. Constructionline publishes these only behind the turnover selector on the sub-contractor memberships page, so run your own band through it rather than trusting a third-party figure — including ours. Our Constructionline cost breakdown covers the methodology and the extras in more detail.

A worked example: an M&E firm asked for Gold

Say you run a 12-engineer electrical and mechanical firm turning over around £850,000, you already hold a valid SSIP certificate from another member scheme, and an FM main contractor has told you their supply chain minimum is Constructionline Gold before they'll issue a £5k-a-year commercial maintenance contract.

1. 1
   Confirm what they actually asked for. "Gold" and "the Common Assessment Standard" mean the same thing here. If the email says CAS, Gold is the level. Get it in writing before you pay.
2. 2
   Price your own band, not a blog's. Put £850,000 into the turnover selector on the Constructionline sub-contractor memberships page. You're paying a joining fee plus the Gold annual fee in year one, then the annual fee only from year two.
3. 3
   Push your existing SSIP through Deem to Satisfy. Rather than sitting a second health and safety assessment, submit your current SSIP certificate to Once For All Health & Safety. That removes the H&S block of the assessment.
4. 4
   Do the non-H&S sections properly. Quality, environmental, equal opportunities and diversity, CSR and the Building Safety Act sections are where Gold applications stall — none of them are covered by your SSIP.
5. 5
   Diarise the renewal the day you're verified. One date, twelve months out, with a reminder six weeks before. This is the bit that costs firms contracts.

The honest arithmetic on that £5k contract: if Gold costs you a four-figure sum in year one and the contract is worth £5,000 a year, it only pays if you keep the client, or if the badge unlocks more than one buyer. Ask the client whether Silver plus your existing SSIP would satisfy them before you commit — some will say yes.

What Constructionline doesn't solve

Being straight about this is more useful than another feature list. Three things stay on your plate.

The renewal treadmill. Constructionline payments are taken annually, and your membership only stays useful while your profile is verified. Expired insurance certificates, out-of-date accounts or a lapsed training record can drop you out of buyer searches without you noticing. If you also hold CHAS or SMAS, you now have two or more anniversary dates running on different clocks — see our guide to accreditation renewal deadlines.

Re-uploading the same evidence. Deem to Satisfy removes the duplicate health and safety assessment, not the duplicate admin. The same employers' liability certificate, the same H&S policy, the same accounts get uploaded to each portal separately, in each portal's format.

The tiers nobody mutually recognises. Constructionline Gold, the Common Assessment Standard and client-specific PQQs sit outside the SSIP mutual recognition arrangement entirely. That's why holding three SSIP-approved schemes still doesn't stop a main contractor sending you a fresh questionnaire.

Frequently Asked Questions

Is Constructionline the same as SSIP?

No. SSIP is an umbrella arrangement for health and safety assessment schemes; Constructionline is a broader pre-qualification database that verifies finances, insurances, standing and more. Constructionline includes SSIP certification through its own member scheme, Once For All Health & Safety, across Bronze, Silver, Gold and Platinum memberships.

Is Constructionline Bronze enough for main contractors?

It depends entirely on the buyer. Bronze verifies identity, financials, insurances and work categories and now carries SSIP, which satisfies plenty of smaller clients. It does not certify you to the Common Assessment Standard, so any contractor mandating CAS will need you at Gold or Platinum.

Do I still need Constructionline if I already have CHAS?

Only if a client asks for it. Your CHAS certificate is SSIP-recognised, so it can be Deemed to Satisfy the health and safety element of Constructionline — but it doesn't put you on the Constructionline database, which is the whole point of membership for buyers who search there.

How much does Constructionline cost for a small subcontractor?

Constructionline's supplier FAQs state that annual membership starts from £399 a year, plus a one-off joining fee for new members, both based on your turnover band and excluding VAT. From year two you pay the annual fee only. Check your own turnover band on the Constructionline sub-contractor memberships page for the current figure.

What's the difference between Constructionline Gold and Platinum?

Gold covers the desktop version of the Common Assessment Standard; Platinum adds a one-day on-site premises audit and covers the site-audit version of the standard. Unless a client has specifically asked for the audited standard, Gold is the usual stopping point for a small subcontractor.
