National Highway Sector Scheme Overview

National Highway Sector Schemes (NHSS) are bespoke integrated quality management systems for organisations working on the National Highways strategic road network, which accounts for approximately 4% of all roads in England. Local Authorities are responsible for the remaining 96% and will often adopt these management schemes.

NHSS use the current ISO 9001 as the basic standard, as well as providing specific requirements and interpretation for individual industries.

There are currently more than 20 NHSS schemes. They cover activities ranging from fencing, landscaping and vehicle safety restraints to road surfacing and marking, and traffic management.

The aim of the scheme is to ensure all work is carried out to the highest standards of professionalism, using a properly trained and registered workforce. They also place a strong emphasis on health and safety.

How to get certified under one or more NHSSs
Before you can be certified and registered under the NHSS, you must be assessed by a certification body accredited by UKAS for the relevant NHSS.

If you already have ISO 9001 certification from either an accredited UKAS certification body or from a recognised national accreditation body accredited certification body, it’s possible to include NHSS certification as an extension to this. See the guide on quality management standards.

Steps to certification
Your first step should be to download the SSDs for each scheme you wish to be registered for. These are available from the Schedule of Suppliers website.

Next, contact a relevant NHSS-accredited certification body to arrange a preliminary audit check, followed by an assessment visit.

The auditors used by certification bodies should have technical knowledge and experience of working in your sector(s).

The audit/assessment will typically consist of:

making sure that your quality manual conforms to ISO 9001 and the relevant sector scheme(s)
confirming the scope of certification, i.e., checking that registration to the NHSS is relevant to the work you plan to do
identifying any actual or potential areas of non-compliance, and developing an action plan to remedy these
What is covered in the assessment can vary depending on the scheme you’re seeking certification for, and the certification body, but normally involves:

carrying out sample audits of your processes and activities
documenting how your systems for quality management comply with the requirements set out in the SSDs and ISO 9001
reporting on any areas of non-compliance, or where there is the potential for non-compliance
Audits are not limited to assessing your processes. Within the NHSSs, there is a strong emphasis on the competency of your personnel, and your organisation’s ability to deliver positive outcomes.

If the assessment reveals any major areas of non-compliance, you’ll need to take action to correct this. The certification body will need to verify the action you’ve taken before it will issue certification against the NHSS.

What happens after you’ve achieved NHSS certification
If you pass the assessment, you’ll be formally notified by the certification body and should receive a certificate, although this varies from body to body. Some will provide individual certificates for each sector scheme, while others may issue certificates that include details of NHSS assessments among other capabilities you may have been assessed on. The scope of your NHSS certificate will be agreed between you and the certification body but will align with the scopes included in Appendix K of the SSD.

Follow-up audits
The certification body will conduct surveillance visits at regular intervals – usually once every 12 months – to make sure that your systems continue to meet the standards needed for certification. You’ll also need to pass a re-certification audit every three years.

Development of new NHSSs
Where a need arises, new NHSSs can be created. This can come from a variety of sources, such as legislation, a change in standards, or client and/or industry requirements.

When such a proposal arises, the proposed NHSS is discussed by the NHSS Liaison Committee, who discuss the commercial and practical viability of the proposed new scheme. If deemed viable, a Technical Advisory Committee for the scheme is formed.

Construction-related competency cards
You must ensure that each of your employees working on projects covered by an NHSS has an appropriately detailed skills card. This provides evidence that the person has all the required skills and training they need for the types of work they carry out on site. The cards should include the CSCS logo or mark (as appropriate) to be valid as meeting the requirements of the Construction Leadership Council.

Additional requirements may be required by the main contractor, for example, supervisor qualifications or the Highways Passport.

The Highways Passport will indicate that you’ve passed the highways common induction test and may also act as a permit to work on the national strategic road network. It may also record the qualifications you hold; however, it’s not recognised as a substitute for a CSCS card.

See the relevant Sector Scheme Documents and the guide on skills card and registration requirements.

They’re developed and maintained by the technical advisory committee for each scheme. Committees are made up of representatives from across the sector, including but not limited to:

contractors
suppliers
client bodies
trade associations
training organisations
certification bodies
The documents describe the committee’s interpretation of the ISO 9001 framework as it applies to a sector including specific requirements for that industry sector. They define minimum standards and requirements for:

workmanship, services, products and testing
training and competency requirements for operatives and supervisors and site management
qualifications for auditors used by certification bodies
specific elements of environmental and other management systems

Benefits Of Certification

NHSS registration is mandatory for all National Highways contract work specified in accordance with the SHW.

There are several advantages for being registered to NHSS if your organisation has previously worked with us, or you plan to tender for future work:

A competitive edge – If you’re already NHSS registered when tendering for work, you may have an advantage over competitors who aren’t
Enhanced business credentials – through independent verification of your processes against recognised quality standards
A better understanding of risk, and how to manage it – The NHSS assessment process can help you pinpoint areas of risk in your operations
New opportunities – If you currently work only on non-national road networks, NHSS registration clears the way toward you taking on contracts for the national strategic road network
Greater visibility to contracting bodies – Once NHSS certified, you’ll be automatically registered on the UKAS Certcheck database by your UKAS-accredited certification body. You may be required to provide information to the certification body to enable it to register your organisation correctly.
Access to expertise and support – Some trade associations will only accept new members who are NHSS-registered

Who Needs To Be Certified?

If your organisation supplies services (including the supply of products but excluding the manufacture of products subject to legal conformity assessment requirements) to National Highways under the Specification for Highways Works (SHW), you must be certified for all the relevant schemes for the work you’re contracted to undertake.

Where the SHW forms part of the contract documentation, an organisation carrying out works covered by a NHSS shall be registered to that NHSS unless stated otherwise in the contract.

You don’t have to be registered to an NHSS where works are subcontracted. Any subcontractor used shall be registered to the relevant NHSS(s). The SHW does not empower an NHSS-certified contractor to provide an umbrella for a non-NHSS registered supplier to carry out all or part of the work.

An NHSS will be relevant to your organisation if it includes any of the following:

Main contractors and contractors who work on the motorway or trunk road network
Main contractors or contractors who work on or beside roads, including those involved in landscaping work
Manufacturers, installers and repairers of products covered by a scheme
Highway designers and consultants

What Happens After You Have Achieved Certification?

If you pass the assessment, you’ll be formally notified by the certification body and should receive a certificate, although this varies from body to body. Some will provide individual certificates for each sector scheme, while others may issue certificates that include details of NHSS assessments among other capabilities you may have been assessed on. The scope of your NHSS certificate will be agreed between you and the certification body but will align with the scopes included in Appendix K of the SSD.

The certification body will conduct surveillance visits at regular intervals – usually once every 12 months – to make sure that your systems continue to meet the standards needed for certification. You’ll also need to pass a re-certification audit every three years.
