A Certificate of Currency is necessary but not sufficient. It tells you a policy existed on the day it was issued. It does not tell you whether the aggregate has eroded, whether a warranty has been breached, whether the indemnity in your sub-contract is enforceable, or whether the named-insureds line carries the principal contractor through. The Sub-Contractor Insurance Verification Pack 2026 is a 4,250-word, broker-written reference for principal contractors, project managers and QSs. It includes a one-page reusable verification checklist and is reviewed by Matt Bartlett, Director.

Chapter 1 sets out why verification matters — the indemnification cascade from employer to main contractor to sub-contractor to sub-sub, the JCT and NEC pass-down mechanisms, and the LADs and insurance interplay that turns a sub-contractor’s default into the main contractor’s loss. Chapter 2 covers the six lines of cover to verify per sub-contractor: Public Liability adequate to contract limit (£10m typical for civils, £5m for finishing trades), Employers’ Liability above the statutory £5m floor, Contract Works with named-insureds and joint-names confirmed, Professional Indemnity for design-and-build sub-contractors with limit basis and retroactive date checked, tools and plant own-damage, motor for plant on the public road, and products liability for installed items. The chapter walks through the difference between the certificate of currency (necessary but not sufficient) and the policy schedule (the substantive document).
Chapter 3 unpacks the indemnity clauses that must be in place — hold-harmless, waiver of subrogation, primary and non-contributing PL, indemnity-to-principals — and the case-law anchor on indemnity scope, including the Canada Steamship line and Anglo-American Construction v Crowley. The chapter also covers Hawley v Luminar on the control test for vicarious liability, which matters for both door staff (the original context) and labour-only construction operatives.
Chapter 4 covers the Work at Height Regulations 2005 duty hierarchy and the LOLER and PUWER interplay for MEWPs, IPAF and PASMA card verification, scaffold contractor certification under NASC TG20:21 and SG4:22 with CISRS cards, and the CSCS Smart Check tool with the 2024-25 tightening of construction skills certification. Chapter 5 compares CHAS, SafeContractor, Constructionline and Achilles UVDB on what they pre-qualify and what they do not. Chapter 6 covers false self-employment under IR35, the Construction Industry Scheme gross/net implications, Modern Slavery Act 2015 section 54 obligations, and the labour-only versus bona-fide distinction at HSE and EL underwriting level.
Chapter 7 closes with the verification checklist — a one-page reusable template covering insurance verification, indemnity and contract, skills and compliance, tax and labour, and re-verification. The pack runs to 4,250 words across 14-16 pages.
Sub-contractor verification is one of the least-formalised disciplines in UK construction. We work with main contractors whose pre-qualification onboarding process is documented, schemed and audited — and whose project-level verification of insurance at the point of engagement is, in practice, a folder of certificates somebody emails over and somebody else saves to SharePoint. The folder is current. The cover is not interrogated. The indemnity clause is whatever the standard sub-contract pulled from the document store. The schedule is rarely read.
This is the gap the pack is built to close. The verification checklist in Chapter 7 is a one-page reusable template designed to be used at the point of engagement and re-applied at policy renewal. It is not an audit framework — it is operational documentation that sits inside the project file and is available to the principal contractor’s insurer at claim or at renewal.
The pack also draws on a deeper point of insurance practice that is often misunderstood: contractor-protective clauses do not, on their own, transfer risk. They allocate risk to insurance — and the allocation only works if the underlying insurance responds. Verification is the discipline that confirms the underlying insurance is in the place the contract assumes it to be.
Can I use the checklist commercially in our supply chain process? Yes. The checklist in Chapter 7 is published as a template for principal contractors to adapt to their own engagement processes. Attribution to Apex is appreciated but not required for internal operational use.
Does the pack address public sector and PFI engagement? The substantive verification framework applies across public and private engagement. PFI, public sector and institutional-funded projects often require additional indemnity-to-principals provision and named-insureds entries — flagged in Chapter 3 — but the core checklist remains applicable.
Is the pack suitable for use by sub-contractors themselves? Yes — from the other side. A sub-contractor reading the pack will see what a competent principal contractor is checking, which is useful for preparing the cover, the certificate, the schedule and the indemnity-clause response.
How often should verification be re-run? Annually at policy renewal as a minimum. For long-running engagements, also at the point of any policy mid-term amendment, change of insurer, or change of indemnity arrangements. The checklist includes a re-verification section.
Does the pack cover the new CSCS framework after the 2024 changes? Yes — Chapter 4 covers the phasing out of Industry Accreditation cards and the requirement for recognised qualifications behind every CSCS card, with the CSCS Smart Check tool as the standard verification mechanism.
The pack is aimed at principal contractors, project managers and QSs in main contractor organisations. It is less directly useful for sub-contractor businesses preparing their own cover (though it provides a useful map of what a competent principal contractor will check), domestic builders engaging individual tradespeople where the verification regime is necessarily lighter, and public-sector procurement teams operating under PAS 91 or equivalent pre-qualification frameworks where the substantive verification is at framework level rather than project level. For these audiences, the pack is a useful reference but may not be the primary working document.
You will receive the pack by email immediately, as a PDF, with the one-page verification checklist as a separately downloadable single-page template.
