A Simple Five-Step Approach to Managing Contractors

Managing contractors well means following a clear, repeatable process: plan the job properly, choose the right contractor, manage them on site, check in regularly and review the finished work. Good contractor management protects your organisation, keeps everyone on site safe and gets the best results from the external help you bring in.

Involving contractors in work projects can be a tall order, especially when they are being introduced into a core team. Seamless contractor management helps your organisation maintain its efficiency and effectiveness, even when additional external help is needed. Organisations need robust pre-planning processes, effective communication, regular check-ins and a final review of the completed work to manage contractors effectively.

Key points:

• contractor management is a fire-step process: plan, choose, onboard, monitor and review
• employers keep legal responsibility for contractor safety even after work is handed over
• construction projects with more than one contractor need an appointed principal contractor under CDM 2015
• contractor management software can support the process, but it does not replace it; and
• formal training, such as the IIRSM Approved Managing Contractors course, builds confidence in applying all five steps.

The easiest way to deliver on this is to follow a simple five-step process and to educate yourself with formal training such as the IIRSM Approved Managing Contractors course.

What Is Contractor Management?

Contractor management is the process an organisation uses to plan, select, monitor and review the work of anyone it engages who is not a direct employee. It covers everything from the first conversation about a job through to signing off the finished work, and at its core it is a form of risk management: identifying what could go wrong and putting sensible controls in place before it does.

A good contractor management process brings together several strands: risk assessment, contractor selection, on-site supervision, ongoing monitoring and a final review. Larger organisations, or those working across multiple sites, often formalise this into a documented contractor management system, sometimes supported by contractor management software, so that the same standards are applied consistently to every contractor and every job.

Under health and safety law, a contractor is simply anyone asked to carry out work who is not an employee. This can range from a single self-employed tradesperson to a large specialist firm with its own workforce, so the contractor management process needs to be proportionate to the scale and risk of the job.

The Benefits of Good Contractor Management

Effective contractor management reduces the risk of accidents, delays and disputes. When contractors understand what is expected of them, sites run more smoothly, and work is less likely to be repeated or corrected later.

Good contractor management also protects an organisation's reputation. Incidents involving contractors can affect employees, other contractors, visiting customers and the wider public, and a poorly managed contractor can undo years of safety culture in a single afternoon. Getting the process right supports:

• fewer accidents and near misses on site
• work completed on time and to the agreed standard
• stronger, more reliable long-term supplier relationships; and
• clear evidence of compliance if an incident is ever investigated.

Common Challenges in Contractor Management

Even organisations with good intentions run into recurring challenges in contractor management. The most common include inconsistent onboarding between sites, out-of-date compliance documents such as insurance certificates or risk assessment and method statements (RAMS), unclear lines of supervision when several contractors work on the same site and a lack of follow-up once the job is finished.

Most of these challenges come down to the same root cause: treating contractor management as a one-off task rather than an ongoing process. The five-step approach below is designed to close those gaps.

Legal Duties When Managing Contractors

Employers have a legal duty to manage the risks that come with using contractors, in the same way they must manage risks to their own employees. The Health and Safety Executive (HSE) sets out that anyone using contractors should identify the job and its hazards, select a suitably competent contractor, assess the risks involved, provide relevant health and safety information, cooperate and communicate with the contractor throughout and manage and supervise the work.

These duties do not disappear once a contractor arrives on site. Employers remain responsible for making sure the agreed health and safety procedures and safety compliance arrangements are actually followed, not just written down, and for communicating health and safety requirements clearly before work begins. Where contractors bring in their own staff or subcontractors, it is worth clarifying in the contracts who holds responsibility for each part of the job, and reviewing those contracts if the scope of work changes.

Principal Contractor Duties Under CDM 2015

Construction work carries its own legal framework. Where a project involves construction, the Construction (Design and Management) Regulations 2015 (CDM 2015) apply, and any project with more than one contractor requires a principal contractor to be appointed.

The principal contractor's duty is to plan, manage, monitor and coordinate the whole construction phase. In practice, this means preparing a written construction phase plan before work begins, checking that everyone appointed has the skills and experience to work safely, giving all workers a site-specific induction and keeping welfare facilities and site security in place throughout. The principal contractor also liaises with the principal designer to make sure information relevant to future work is captured in the health and safety file, a record that is handed to the client at the end of the project for use by anyone carrying out maintenance, repairs or further construction later on.

Five Steps to Managing Contractors Effectively

The health and safety process does not start when the contractor first arrives on site. It includes preparation beforehand and ongoing review throughout, built around five steps: plan, choose, onboard, monitor and review.

Step One: Plan Accordingly

Define the job

Ensure you are clear about all aspects of the work you would like the contractor to be involved in. Cover all aspects of the planning and completion processes, and put this in writing so there is a shared reference point if questions come up later.

Identify and control risks

Bringing in a contractor is a significant change in variables. As is always the case when changes happen in a workplace, it is essential to conduct a fresh risk assessment to identify hazards and implement control measures. This is also the point to gather the compliance documents you will need before work starts, such as method statements, insurance certificates and any permits.

Specify conditions for work

Setting expectations in your initial discussions with contractors is a pivotal step in the process. Run them through health and safety arrangements, emergency procedures, permit systems and organisational policies. Put the agreed terms into a formal contract, and ensure the contractor confirms their understanding and agreement to work within these parameters.

Step Two: Choose a Contractor

Contractor selection should weigh up several factors, including:

• availability
• cost
• technical competence; and
• reliability.

Take reasonable steps to determine the contractor's degree of competence so that a lack of knowledge does not increase the risks involved in the work. Look for demonstrations of competence, such as success on a similar job in the past. Other things to look at include:

• qualifications
• health and safety training, for example IOSH Managing Safely or NEBOSH General Certificate, which can also be completed in anticipation of the work at hand; and
• memberships of relevant trade or professional bodies.

Establish whether subcontracting is acceptable for this work, and consider how that will affect health and safety and overall contractor management.

Step Three: Onboarding Contractors on Site

Good onboarding sets the tone for the whole job. Arrange for visitor sign-in controls and, where necessary, permits-to-work. Before work begins, confirm:

• the number of people involved and the details of their supervisor
• correct work equipment and personal protective equipment (PPE) have been provided and used
• access to the location is addressed and agreed; and
• any necessary communications and monitoring are in place, such as regular meetings or briefings.

As a courtesy, existing staff should be involved and informed of the contractor's role from the start. Where several contractors' workers are on site at once, it is worth naming a single point of contact to keep communication and safety management consistent.

Step Four: Monitor and Check In

Check in regularly with the contractor to ensure communication channels stay open. Assess the degree of contact needed beforehand, depending on the scale and risk of the work; higher-risk jobs need more frequent inspections and closer monitoring. In these check-ins, be sure to ask:

• Is the job going as planned?
• Is the contractor working safely and in line with agreed safety compliance? It is also worth checking with other employees.
• Have there been any incidents?
• Have there been any changes in personnel?

Step Five: Review, Audit and Document the Work

Review the job on completion, along with the contractor's performance. How effective was your planning process? Did the contractor perform as expected? Note any difficulties and make necessary changes for next time.

Keeping documentation from this stage, such as sign-off records, incident reports and any updates needed for the health and safety file, gives you a paper trail to draw on for future jobs. Organisations that manage a lot of contractor work often build periodic audits into this final step, checking a sample of past jobs against agreed safe work systems and practices to catch problems before they become patterns.

Using Contractor Management Software and Systems

As the volume of contractor work grows, tracking everything on spreadsheets and email becomes hard to sustain. This is where contractor management software comes in. Rather than replacing the five steps above, good software supports them by centralising the information each step depends on.

An effective contractor management system typically includes features such as:

• a central record of compliance documents, including insurance certificates, qualifications and RAMS, with automatic reminders before they expire
• online induction and onboarding for contractors before they arrive on site
• sign-in and permit-to-work tracking for workers on site
• a record of inspections, audits and any incidents involving contractors; and
• reporting that shows contractor performance over time.

Some organisations use a dedicated contractor management platform, while others rely on a contractor management module built into a wider health and safety management or facilities management system. Either approach can improve both efficiency and compliance, provided the underlying process, not just the software, is sound.

Social Value in Contractor Selection

Increasingly, organisations weigh up social value alongside cost and technical competence when choosing a contractor, particularly in construction and public sector work. Under the Public Services (Social Value) Act 2012, public bodies must consider how procurement can bring wider economic, social and environmental benefits, such as local employment, apprenticeships or community investment. Many private sector organisations now apply similar criteria when reviewing contractor selection as part of their own sustainability commitments.

Training Courses for Managing Contractors in the Workplace

For those who are responsible for contractor work or health and safety in the workplace, formal training in this subject is strongly recommended. Courses such as the IIRSM Approved Managing Contractors course provide methods of assessing, selecting, planning, monitoring and reviewing competent contractors, and cover the legal duties set out above, including CDM 2015. This guide, combined with formal training, leaves learners well placed to manage contractor workflows confidently and ensure organisations move with maximum efficiency.

Frequently Asked Questions About Managing Contractors

What is the difference between contractor management and facilities management?

Contractor management is the process of planning, selecting, monitoring and reviewing contractors who carry out work on your behalf. Facilities management is broader: it covers the day-to-day running of a building or site, of which managing contractors, such as cleaning, maintenance or security providers, is usually one part.

Who has a duty to manage contractor health and safety? 

The organisation hiring the contractor generally retains the duty to manage risks arising from that work, alongside the contractor's own responsibility for its workers. On construction projects with more than one contractor, this duty sits specifically with the appointed principal contractor.

What compliance documents should I collect before a contractor starts work? 

At a minimum, collect evidence of relevant qualifications, health and safety training, public liability and any other required insurance, plus a risk assessment and method statement for the specific job. Keep copies on file as part of your contractor management documentation, and check expiry dates before renewing the contract.

Do small jobs need the same contractor management process as large ones? 

The five steps still apply, but the amount of documentation and monitoring should be proportionate to the risk. A short, low-risk job might need a brief written scope and a single check-in, while higher-risk or longer projects justify a fuller contractor management system, more frequent inspections and formal audits.

Is contractor management software worth it for a small organisation? 

It depends on the volume and risk of the contractor work involved. Organisations that manage only occasional, low-risk contractors can often run an effective contractor management process with well-organised documentation. Once the number of contractors, sites or compliance documents grows, dedicated software or a contractor management module tends to pay for itself in time saved and risks caught early.

What should happen if a contractor is not working safely?

Stop the work if there is an immediate risk, then address the issue directly with the contractor's supervisor. Record what happened, agree on corrective action and follow up at the next check-in to confirm safety compliance has genuinely improved, rather than assuming a verbal agreement has fixed the problem.
