Construction

Build a solid foundation for your organisation’s future

Key Statistics

  • Total construction output in the UK is forecast to grow by 3.7% in 2026. Private housing is expected to grow by 7%. Increasingly, these growth areas are tied to compliance with ISO 14001 for environmental management, as regulatory and client expectations rise for sustainable project delivery.
  • The construction industry recorded the highest number of workplace fatalities in the UK in 2024/25, accounting for 35 out of 124 in total. This underscores the importance of robust Health and Safety Management Systems in the sector.
  • The buildings and construction sector is estimated to contribute significantly to global emissions, with estimates of up to 37% of global emissions when including operational and embodied carbon.

Construction is one of the most regulated industries in the UK due to the heightened risk of workplace hazards, as reflected in annual Health and Safety Executive (HSE) statistics on injuries and fatalities. Maintaining a safe working environment may help reduce the likelihood of enforcement action and help sustain positive relationships with clients and buyers.

ISO certification is a valuable consideration for construction businesses, as it can support and strengthen multiple areas of a project – including supply chain management, cost control, project timelines, and workforce safety.

With complex regulations and demanding client expectations, certified management systems provide a structured approach for organisations to support process efficiency and keep track of compliance activities. ISO certification could help construction businesses stand out to prospective clients and may strengthen their position when tendering for new contracts by supporting efforts to address industry challenges and demonstrate compliance with relevant standards.

Additionally, SSIP (Safety Schemes in Procurement) certification may also help construction businesses demonstrate their approach to health and safety management and could help reduce duplication in pre-qualification processes.

Key Certifications for the Construction Industry

ISO 14001 (Environmental Management)

Specifies requirements for an Environmental Management System (EMS), supporting the control of waste, use of resources, and environmental impact across construction activities.

ISO 27001 (Information Security)

Defines the requirements for establishing, implementing, and maintaining an Information Security Management System (ISMS), relevant to the handling of digital project data and client information.

ISO 45001 (Health and Safety)

Provides the requirements for Occupational Health and Safety (OH&S) Management, with a focus on identifying, managing, and reducing risks on construction sites.

ISO 9001 (Quality Management)

Sets out the requirements for a Quality Management System (QMS), emphasising consistent processes, documentation, and continual improvement throughout construction projects.

SSIP

The UK umbrella scheme created to standardise and simplify health and safety pre-qualification for contractors and suppliers, allowing mutual recognition across member assessment schemes.

The Benefits of ISO Standards for Construction Companies

ISO 9001

Achieving ISO 9001 certification may help organisations establish consistent quality management processes and demonstrate a commitment to quality to clients and supply chain partners. Implementing ISO 9001 can support efforts to streamline operations, and certification provides independent verification of this conformity.

We know managing quality in the construction industry involves oversight throughout the entire project life cycle, from design and specification to material selection and resource management, customer service, and final handover. Maintaining effective quality management processes can support project delivery, client satisfaction, and reputation in a competitive market.

A Quality Management System (QMS) certified to ISO 9001 provides a recognised set of requirements for controlling quality-related activities across projects. Certification may help clients and stakeholders feel confident in an organisation’s capability and commitment to meeting requirements.

Compliance in construction extends beyond legislation to include industry standards and client requirements, particularly for organisations seeking to tender for contracts.

For example, Building Information Modelling (BIM) is becoming increasingly relevant in construction. The UK Government requires suppliers to meet BIM Level 2 for centrally-procured projects. The adoption of BIM introduces new challenges for document control and quality management due to the volume and complexity of digital information.

Having an established quality management system may help organisations adapt to these changes and align processes with BIM requirements.

ISO 45001

Safety is a significant concern in the construction industry. ISO 45001 may help organisations demonstrate the importance of health and safety management to stakeholders, clients, and the public. Certification may also support efforts to meet requirements when tendering for contracts and demonstrate an organisation’s commitment to effective health and safety management.

The Health and Safety Executive (HSE) advises that organisations seeking ISO 45001 certification should use a certification body that is accredited by the United Kingdom Accreditation Service (UKAS).

When issued by a UKAS-accredited body, such as British Assessment Bureau, ISO 45001 certification is recognised by SSIP as satisfying the competency requirements of the CDM regulations. This recognition is accepted across all SSIP member schemes.

ISO 14001

ISO 14001 certification may help construction companies demonstrate their approach to minimising environmental impact across projects. Many construction tenders now request evidence of environmental management systems, reflecting the sector’s focus on sustainability and regulatory compliance.

The construction industry is subject to a wide range of environmental regulations, from land impact assessments to waste management. With sustainability increasingly prioritised, clients and buyers are seeking partners who can show responsible environmental practices.

An environmental management system can help support compliance monitoring and continual improvement efforts. Formal certification to ISO 14001 may support tender responses where environmental management credentials are evaluated.

SSIP

SSIP (Safety Schemes in Procurement) certification may help construction businesses demonstrate recognised health and safety management to clients and principal contractors. Mutual recognition between approved schemes could help reduce duplication and save time during pre-qualification.

The Construction (Design and Management) (CDM) Regulations set out key responsibilities for duty holders to ensure safety and risk reduction throughout every stage of a project. Meeting procurement requirements often involves assessment through health and safety schemes, and SSIP can help streamline this process.

This type of certification may be relevant if you operate in roles such as Principal Contractor, Designer, or Consultant.

In many cases, ISO 45001 certification by a UKAS-accredited body is recognised within SSIP schemes, helping reduce duplication.

27001

ISO 27001 certification helps construction companies protect sensitive information from cyber threats and data breaches which is becoming an increasing threat generally. With the increasing digitalisation of construction through Building Information Modelling (BIM) and cloud-based project management systems, robust information security has become important for maintaining client trust and protecting commercially sensitive project data.
