Approved Contractor List

The approved contractor list is the standing register of who may be engaged at all: each contractor, their risk tier, the categories they hold approval for, when that approval expires, and whether insurance and clearances are live. Its recurring failure is being read as more than that. It is the only contractor document that reaches the gatehouse, so it answers a question it was never built to answer: may these people start this job now.

The gatehouse before a pass, procurement before an order

The short version

  • The list is a control at two moments only: security issuing a pass and procurement raising an order. Security Checks This List and Procurement Checks This List decide whether you have a control or an artefact.
  • A register decays by being left alone. Expired Approvals Still Listed and Insurance Lapsed are not data-entry errors, they are the resting state of any list nobody sweeps, which is what Last Reviewed and Next Review Due exist to force.
  • Contractors Used Without Approval is the only number here that measures the list's authority rather than its content. A zero is almost always an uncounted zero, because the bypass happens at four in the morning and is signed in as a visitor.
  • Work Categories Approved is procurement language. Mechanical or refrigeration describes what a firm sells, not what it may do in your plant room, and a free-text restrictions field is not readable as a permission. Scope belongs in its own record.
  • The row should be derived from the approval, insurance and clearance records, not retyped from them. Approved Until and Insurance Current are already facts elsewhere, and a stored copy of a fact will disagree with its source inside a quarter.
  • One list for the group, not one per site. A contractor suspended at one plant and still approved at the next is the standard failure, and it is a data-model problem rather than a discipline problem.

What this is

What is an approved contractor list?

What is an approved contractor list?

It is the register of contractors who have been through approval and may currently be engaged, with the tier, categories, approval reference and expiry that make each row checkable. It is master data rather than an event record: built once, amended whenever an approval changes, reviewed on a stated cycle. Its value is in being the single place two people look before anyone starts.

How is the list different from the vendor register?

The Vendor and Contractor Register holds everyone the business buys from, including firms that will never set foot on site. The approved list is the subset holding a live approval to work here, with the expiry and assurance state attached. The register is a commercial record and the list is a safety control, which is why the list carries the Approval ID and the register does not.

What does being on the approved list actually permit?

Engagement, and nothing more. A row says this company has been assessed, is insured, holds current clearances and may be given work in these broad categories. What they may do, where and under what supervision belongs in the Contractor Scope Record; authorisation for a job on a shift belongs in the access authorisation and the permit. Read as a permission, the list overstates itself in the direction that hurts.

Scope

When is an approved contractor list required?

This is master data. It answers a single question, whether a contractor may be engaged, and every neighbouring record answers a different one. Collapsing them into the list is tempting because the list is what people actually open, and it is how a register becomes a licence.

Use this template when

  • A contractor programme is being set up and one authoritative answer is needed to who may be engaged
  • Security or reception needs a single check before issuing a contractor pass
  • Procurement needs a check before raising an order or a call-off against a term arrangement
  • A periodic review of approvals, insurance and clearances is due and the exceptions need counting
  • A group needs one register across sites, so an approval or suspension at one site is visible at the others

Do not use it for

  • Approving the contractor in the first place, which is the Contractor Approval Record (CON-004) resting on prequalification, statistics, insurance and references
  • Recording what a contractor may and may not do, which is the Contractor Scope Record (CON-034); the categories column here is a filter, not a permission
  • Removing or stopping a contractor after a failure, which is the Contractor Suspension Record (CON-035); the list carries the consequence, not the decision
  • Judging how a contractor performed, which is the Contractor Performance Scorecard (CON-014) and Contractor Final Evaluation (CON-032); the list holds the last rating, never the argument behind it
  • Holding every supplier the business buys from, which is the Vendor and Contractor Register (FDN-005); this list is the subset cleared to work on site

Compliance mapping

Which ISO 45001 cl.8.1.4 requirements does this satisfy?

Standards ask for the control rather than the artefact: procurement of services governed by defined criteria, external providers selected and monitored against those criteria, and the resulting information identified, reviewed and available where it is used. A maintained approved list is the ordinary way all three are evidenced at once.

What it does not cover

  • Contractor Approval Record (CON-004), which holds the decision and the evidence behind a row; the list carries the Approval ID because it points at that record rather than replacing it.
  • Contractor Scope Record (CON-034), which states approved categories, areas, high-risk activities and exclusions; a category column and a restrictions field cannot carry a permission.
  • Insurance Certificate Record (CON-020) and Insurance Expiry Review (CON-023), which hold the certificates, limits and endorsements; Insurance Current is a flag, and a flag is not cover.
  • Workers Compensation Clearance (CON-021), the clearance letter the jurisdiction issued, with its reference and date; Clearance Current summarises it and cannot be produced in its place.
  • Site Access Authorization (CON-013) and the permit to work, which authorise these people, this task, this shift; a live row is a precondition for both, never an authorisation.

Global

Approved Contractor List requirements by country

Nowhere is a document called an approved contractor list mandatory. What several regimes do make mandatory is that you evaluated a contractor before engaging them and can show it, which in practice means a register or a very good memory.

United States

OSH Act 5(a)(1); 29 CFR 1910.119(h)(2); Multi-Employer Citation Policy CPL 02-00-124

Host employers must obtain and evaluate contract employer safety performance before engagement on covered processes, and controlling employers are cited for hazards they could have prevented.

On a site with an ammonia or other covered process, engaging a contractor with no prior evaluation is a citable gap in itself, whether or not anything went wrong.

United Kingdom

CDM 2015 reg.8; MHSWR 1999 reg.11; HSWA 1974 s.3

Appointments are limited to those with the skills, knowledge, experience and organisational capability for the work, and employers sharing a workplace must co-operate.

The appointment duty is scoped to the work, so a register holding tier and expiry but nothing about capability for particular work meets only half of reg.8.

European Union

Framework Directive 89/391/EEC art.6(4); Directive 2014/24/EU arts.57 and 58

Employers must co-operate where undertakings share a workplace, and public bodies apply documented selection criteria and may exclude for deficient prior performance.

Member states differ on retention and format rather than on the duty, and on publicly funded sites the register is what makes a selection reviewable.

Canada

Provincial OHS statutes with prime contractor regimes; the due diligence standard

Owners, constructors and employers each carry duties, and due diligence is judged on what was known before the engagement and what was done.

A dated register with the evidence one step behind each row is the standard due diligence artefact, and its gaps read as knowledge the employer avoided.

Australia

Model WHS Act s.19 and s.46

A PCBU owes duties to workers whose activities it influences or directs, and duty holders must consult, co-operate and co-ordinate.

Engaging a contractor is an exercise of influence, so the register is how a PCBU shows it engaged on a basis rather than on familiarity.

International

ISO 45001 cl.8.1.4 with ISO 9001 cl.8.4.1 and BRCGS Issue 9 cl.3.5.3

Procurement of services governed by criteria, external providers monitored and re-evaluated, and an up-to-date list of approved service providers maintained.

Food and quality auditors ask for the list first and then for the evidence behind one row, so the register is the entry point into the whole programme.

How to complete it

How to complete an approved contractor list, step by step

This list is easy to build and hard to keep true, and nothing in the form tells you when it has stopped being true. Four judgements decide whether it will be trusted at a gatehouse.

Derive the rows, do not retype them

Approval ID, Approved Until, Insurance Current, Clearance Current, Last Scorecard Rating and the audit dates already exist in the approval, insurance, clearance, scorecard and audit records. Every one stored as a second copy here will diverge from its source, usually within a quarter and always without warning. Link them where the platform allows; where a manual copy is unavoidable, the review interval is doing the work of the link and must be short enough to catch a lapse before the gate does.

Fix the per-row status values before anyone reads it at a gate

The Status field inside the repeating Contractors section ships with the generic record workflow values, which describe the progress of a form rather than the standing of a contractor. A gatehouse needs a different vocabulary: active, conditional, suspended, expired, removed. List health also counts Suspended Contractors while nothing on the row can express suspension. Reconfigure that option set first, because a row reading In progress or Closed will be read at speed and read wrongly.

Count the breaches, not the compliances

Expired Approvals Still Listed, Insurance Lapsed and Contractors Used Without Approval are the three numbers worth anything here, and all three read zero on any list nobody has reconciled. Take the gate log and the purchase order extract for the period and match them against the rows; that reconciliation is the exercise, and its numbers are the only honest measure of the register's authority.

Give the emergency route a definition rather than a prohibition

There will be a burst main at three in the morning and somebody will ring a firm they trust. The form asks whether an emergency engagement process is defined because the alternative to defining one is not compliance, it is an unrecorded engagement signed in as a visitor. Name the checks that fit in ten minutes, insurance evidence, a short induction, escorted access, a named authoriser, and a retrospective approval deadline, and publish that route beside the list.

What auditors find

Most common approved contractor list findings

Findings here come from comparing the list with something else: the gate log, the purchase ledger, the certificate file, or the same list at the site next door. Read on its own, an approved list almost always looks well kept.

FindingClauseWhat fixes it
Contractor on site and working with no row on the list; the order was raised against a familiar name.ISO 45001 cl.8.1.4.2Make the list check a condition of raising the order, and reconcile gate sign-ins monthly.
Rows whose Approved Until date has passed still presented as approved.ISO 9001 cl.8.4.1Expire the row on the date and require a renewal record to restore it, rather than a manual edit.
Insurance Current shows Yes while the certificate held on file expired months earlier.ISO 45001 cl.8.1.4.1Drive the flag from the certificate record's expiry; never let it be set by hand on the list.
Security issues contractor passes from reception's own spreadsheet rather than from this list.BRCGS Issue 9 cl.4.2Retire the local copy and make this register the only source for issuing a pass.
Contractor suspended at one site remains approved on another site's list within the same group.ISO 45001 cl.7.4Hold one group register with a site column, so a single decision changes every site's answer.
Work Categories Approved recorded with no scope record behind the row, so categories read as permissions.ISO 45001 cl.8.1.4.2Hold a scope record per contractor per site and surface it wherever the row appears.
Last Reviewed more than a year old, with Next Review Due already in the past.ISO 45001 cl.7.5.2Set the interval by the shortest expiry tracked, and raise the review as a task, not a date.
Contractors Used Without Approval recorded as zero with no reconciliation carried out.ISO 9001 cl.8.4.1Evidence the gate log and purchase order comparison before that field can be answered.
Action Required set to Yes with no CAPA reference, no priority and no owner.ISO 45001 cl.10.2Raise the corrective action first and enter its reference; a flagged exception with no owner is a closed one.
List held as a spreadsheet on one buyer's drive, unavailable to the gatehouse out of hours.ISO 45001 cl.7.5.3Publish it where the check happens; availability at the gate is part of the control.

Case in point

Case in point: the register that was immaculate and the drain that was not

A three-site ready-meals group kept a genuinely good approved contractor list. Reviewed quarterly by a buyer who cared, expiries current, insurance and clearance flags accurate, two signatures on every revision. At four on a Sunday morning a wash-down bay drain backed up and the shift manager rang a local drainage firm he had used at a previous employer. They arrived within the hour, were signed in at the gate under visitors because there was no row to check them against, jetted the drain, wrote nothing down, and left before the day shift.

Six weeks later a customer audit asked a question nobody had asked before: match the contractor sign-ins in the gate log to the approved list. Eleven engagements in twelve months had no matching row, four of them in open product areas. One was a refrigeration engineer who had attended a chiller alarm and worked alone in a chill store overnight. None appeared in Contractors Used Without Approval, recorded as zero at each quarterly review, honestly, because nobody had ever compared the two lists.

The register was not the problem and improving it would have changed nothing. What the site lacked was a defined route for the four in the morning problem, and a gatehouse category that could not be used to route around the list. The corrective actions were narrow: an emergency engagement route with four checks and a seventy-two hour retrospective approval deadline, removal of the visitor category for anyone arriving to work, and a monthly gate-log reconciliation that produced the honest number instead of the comfortable one.

Run it with agents

From a document you fill in to a programme that runs itself

The register is rarely wrong on the day it is reviewed. What fails is everything around it: the certificate that expired between reviews, the order raised without a check, the gate category that lets work in as a visit, and the site next door that never heard about the suspension.

KnowContractor

Holds the list as a view over the approval, insurance, clearance, scorecard and scope records, so a row cannot read approved once the evidence behind it has lapsed.

KnowSafe

Puts the check where the decision happens, at the gate and the permit desk, so no pass or permit is issued to a contractor without a live row and a scope behind it.

KnowComply

Keeps the register and its review history in the form a customer or certification auditor asks for, with the evidence behind any row one step away.

Ella
Ella

Watches approaching expiries, lapsed insurance and gate sign-ins with no matching row, raising the exception in the week it happens rather than at the next audit.

Glossary

Approved Contractor List definitions and key terms

Approved contractor list
The standing register of contractors who may currently be engaged, with tier, categories, approval reference and expiry, checked before a pass or an order.
Vendor and contractor register
The wider commercial record of everyone the business buys from, of which the approved list is the subset cleared for site work.
Approval expiry
The date an approval lapses, after which the row is not a stale entry but a positive statement that engagement is no longer permitted.
Risk tier
The classification that sets how much assurance a contractor needs, driven by the work they do rather than the size of the firm, and which sets review frequency.
Work category
The broad trade grouping a contractor is approved within, describing what they sell; a filter for engagement rather than permission to perform any particular task.
Workers compensation clearance
The jurisdiction's confirmation that a contractor's cover and contributions are current, which lapses on its own timetable, independently of approval.
Emergency engagement
A defined fast route with a reduced but explicit set of checks and a retrospective approval deadline, so urgent work does not bypass the register.
Unapproved engagement
Work carried out by a contractor with no live row on the register, normally found by reconciling gate logs or purchase orders, not by anyone reporting it.

FAQ

Frequently asked questions about approved contractor list

Is the approved contractor list the same as the vendor register?+

No, and merging them is a common and costly simplification. The vendor register is commercial and includes suppliers who will never attend site; the approved list is a safety control over a smaller population, with expiries, tiers and assurance flags. Keep the list as a view over the register, linked by Vendor ID.

How often should the list be reviewed?+

Quarterly if the rows are typed, continuously if they are derived. The right interval is set by the shortest thing the list tracks, usually an insurance certificate or a clearance letter, and an annual review of a register holding twelve-month insurance dates guarantees a window in which the list is confidently wrong.

Can a contractor stay on the list with no current work?+

Yes, and pruning them is a mistake sites regret. Approval and engagement are different states, and the dormant approved contractor is the alternative supplier you need on the day the incumbent is suspended. Keep them, keep their assurance current, and let the risk tier decide how much a dormant row is worth.

What do we do about genuine emergencies?+

Build the route rather than the prohibition. Define the checks that fit in ten minutes, insist on escorted access and a named authoriser, and set a retrospective approval deadline. A policy saying all contractors must be pre-approved, offering no alternative, produces unrecorded engagements, the outcome it was written to prevent.

Should the list say what each contractor may do?+

It should show it and not hold it. The permission belongs in the Contractor Scope Record, with the areas, high-risk activities and exclusions; the list carries a short scope summary and a link, so whoever reads the row at the gate sees the boundary rather than inferring one from a category. A list with no scope on it is read as a licence, and that is how work starts outside the approval.

One list for the group or one per site?+

One for the group, with a site column and site-specific conditions on the row. Per-site lists fail the same way every time: a contractor is suspended at one plant on Friday and works at the next on Monday, because the decision changed a spreadsheet rather than a register. Where sites differ, the difference belongs in the row's conditions, not in a separate list.
