The Process The Process

Getting certified couldn’t be simpler. Following these four steps and quickly find yourself on the path to accreditation.


Your dedicated Assessor will be in touch to set the scene and get you thinking about how best to communicate and involve others so you can achieve certification in record time.


There’s no pressure for the first ‘Stage 1 Assessment’; you’ll be surprised what you already have in place prior to our visit.

Whilst we do not provide consultancy – so that we maintain impartiality – the unique template toolkit we have developed makes certification achievable with no previous experience.


When you’re ready, your Assessor will visit again for your ‘Stage 2 Assessment’ where you’ll be told the result on the day.

Once our compliance team have reviewed the report, we’ll confirm your certification. You’ll then be sent your certificate, alongside those important logos. Our marketing team is also on hand to help you spread the news about your achievement.


OHSAS 18001 is so revered because of its requirement for continuous improvement, which involves a commitment to being assessed every 12 months.

We’ll contact you to arrange a quotation in plenty of time for you to make a decision. For those with existing certification, we are pleased to offer our Transfer switching service.

Cost Cost

OHSAS 18001 has emerged as the preferred standard and according to Cork University's study, less than half the cost of rival schemes.


The cost of certification is ultimately determined by factors such as the organisation’s total size, the sector it’s in, and the number of locations they operate from. Regardless of your size, we always provide a fixed fee with no hidden costs to worry about. To make budgeting your ISO requirements a little easier, we offer a monthly payment plan as standard to all registered companies, charities and organisations*. If this option is taken an initial payment of only 20% is required with the balance payable over 10 monthly direct debit payments. Alternatively, if you wish to pay the full fee up front a 10% discount will be applied.

*Credit check is not required subject to confirmation of company registration, minimum 6 months trading history and self-certification of solvency. This option is not available to sole traders due to consumer regulations.


So you can take immediate advantage, we provide a Letter of Commitment once you begin the process. You’ll be introduced to your Assessor who is with you throughout the process, together with your Account Manager. With our free template toolkits and online training, this approach has allowed thousands to achieve hassle-free certification in just a few months.

What is OHSAS 18001? What is OHSAS 18001?

OHSAS 18001 is a globally recognised occupational health and safety standard. Sharing much in common with ISO standards, it sets out requirements to create management system in order to control health and safety threats, as well meet legal requirements. The system sets out the basic requirements for occupational health and safety management, as well as the best practice. Ultimately, it aims to ensure all employees are kept safe from harm throughout the course of their working day.

How long does certification take? How long does certification take?

There’s no black and white answer for this question. The amount you’ll end up spending will depend heavily on a number of factors which are specific to your organisations. The three key areas to consider are:

  • Your core business service – Naturally, the length of time to implement a scheme which champions the concept of health and safety in the workplace will vary dependent on what it is your company actually does. If you work in a single-room office, where the bulk of tasks are done sitting behind a desk, it’s going to be a relatively “simple” process. If you work in an industry like construction, things are going to be very different. The risk are more prevalent.
  • How big your company is – If you’re a workforce still in single digits, it’ll be quicker to assess what precautions or risks need to be taken into account. By the same virtue, larger organisations will take longer to assess.
  • Resources you have available – Does your company have the resources available to effectively manage an OHSAS 18001 project from start to finish? The more expertise and knowledge the person at the helm of the operation has, the quicker it’s likely to get completed.

OHSAS 18001 History OHSAS 18001 History

The OHSAS 18001 standard was developed to bridge the gap where no international standard existed for occupational health and safety. Development involved input from a number of leading bodies, including certifiers, trade bodies and expert consultancies.


The first version of the standard appeared in 1999 and was based on a number of existing standards (including BS8800:1996) that had been developed by the leading national certification bodies.


The current version of the standard is OHSAS 18001:2007. This supersedes OHSAS 18001:1999, which was phased out in July 2009.

Despite not currently being an ISO standard, OHSAS 18001 has been designed to be compatible with the ISO 9001 (Quality) and ISO 14001 (Environmental) standards, thus helping organisations to achieve an integrated management strategy.


In 2016, a new Health and Safety Management System standard called ISO 45001 is expected to be published – this will then supersede OHSAS 18001.

The OHSAS 18001 standard specifies a number of key criteria for an organisation to demonstrate and includes:

  • Planning for hazard identification, risk assessment and risk control
  • Structure and responsibility
  • Training, awareness and competence
  • Consultation and communication
  • Operational control
  • Emergency preparedness and response
  • Performance measuring, monitoring and improvement
