Benefits of Accreditation

Confidence in the market place and in our public services is essential. Trust is placed in the products and services on offer often without a second thought by the customer, such are the regulations and standards against which products are manufactured and services provided.

The benefits of accreditation are many. Accreditation can help:

  • Improve your product’s or system’s quality and safetyt
  • Demonstrate your market accountability
  • Bring you global recognition
  • Reduce costs and increase efficiency
  • Reduce your risk
  • Offer you a competitive advantage

For Government

Accreditation is increasingly being recognised as a valuable tool across a wide range of Government policy areas including better regulation, good governance, fair markets and public confidence. It is already being used by Government as an effective market-led tool for delivering policy more efficiently and to help deliver on its obligations in areas as diverse as healthcare, food production, energy supply, climate change and personal safety.UAS has well-established, transparent and repeatable assessment procedures applicable to all forms of conformity assessment, and so the benefits of collaborating can:

  • Accreditation provides the assurance for Government to rely on commercial providers of evaluation and inspection services.
  • Build business and public trust
  • Provide an alternative to Regulation whilst ensuring the reliability of activities that have the potential to impact on public confidence, health and safety or the environment.
  • Enable innovation in the private and public sectors
  • Reduce your risk
  • Offer you a competitive advantage

There are many duties placed on government departments, local authorities and other agencies to ensure that trust is maintained. Whether it be health, water quality, food, consumer goods or transport safety, for example, the public sector provides the framework for the assurance that goods and services are safe and the environment we live in is clean and secure. UAS is already in collaboration with a range of government departments that are now developing schemes to either raise standards or implement new ones as a means of increasing public confidence.

For Business

Companies buy independent evaluations either through choice (to reduce the risk of product failure for example) or as a consequence of legal requirements (such as health and safety regulations). Most commonly these evaluations are calibration of equipment, product testing, inspection of equipment and certification of management systems.

  • Selecting an accredited organisation is an essential tool for decision-making and risk management.
  • Organisations can save time and money by selecting an accredited and therefore competent supplier.
  • Reliable measurements, tests and inspections are carried out in compliance with best practices to limit product failure and reduce down time and control manufacturing costs.
  • Accreditation to internationally-recognised standards can provide a competitive advantage and facilitate access to export markets.

For Accredited Organisations

In some sectors, accreditation is a requirement to obtain accreditation before offering certain services; in others it is a de facto ‘licence’ to trade in that key purchasers expect it. It provides the following benefits:

  • Competitive advantage: accreditation provides independent assurance that your staff is competent. It can sets you apart from the competition, and enable you to compete with larger organisations.
  • Market access: accreditation is specified by an increasing number of public and private sector organisations.
  • Accreditation can highlight gaps in capability, thereby providing the opportunity for improved organisational efficiency and outputs
  • There are a number of insurance brokers and underwriters that recognise accreditation as an important factor in assessing risk, and can therefore offer lower premiums.

A symbol of assurance

Third-party accreditation, the type that UAS provides is recognised around the world as the highest and most credible type a certification or inspection body can obtain.With such accreditation you automatically send a signal to your clients that they can be confident in what you do. This is increasingly important in a market that is growing quickly in size and complexity a market that includes many bodies operating without any such credentials.

UAS accreditation gives you the ability to:

  • Highlight your competence
  • Demonstrate your independence
  • Increase likelihood of smooth access to overseas markets (through our formal arrangements with international accreditation organisations)
  • Build confidence in your ability through benchmarking performance against other accredited bodies.
