It also includes requirements for the assessment and treatment of information security risks tailored to the needs of the Organisation. The requirements set out in ISO/IEC 27001:2013 are generic and are intended to be applicable to all Organisations, regardless of type, size or nature.	SHOULD	A valid ISO 27001:2013 Certificate is required from a UKAS accredited and registered certification Organisation.
ES5.0	ISO 9001 - Quality management systems	ISO 9001:2015	ISO 9001:2015 specifies requirements for a quality management system when an Organisation: a) needs to demonstrate its ability to consistently provide products and services that meet customer and applicable statutory and regulatory requirements, and b) aims to enhance customer satisfaction through the effective application of the system, including processes for improvement of the system and the assurance of conformity to customer and applicable statutory and regulatory requirements.

ES7.0	ISO 14001 Environmental management systems	ISO 14001:2015	ISO 14001:2015 specifies the requirements for an environmental management system that an Organisation can use to enhance its environmental performance. ISO 14001:2015 is intended for use by an Organisation seeking to manage its environmental responsibilities in a systematic manner that contributes to the environmental pillar of sustainability. ISO 14001:2015 helps an Organisation achieve the intended outcomes of its environmental management system, which provide value for the environment, the Organisation itself and interested parties. Consistent with the Organisation 's environmental policy, the intended outcomes of an environmental management system include: · enhancement of environmental performance; · fulfilment of compliance obligations; · achievement of environmental objectives. ISO 14001:2015 is applicable to any Organisation , regardless of size, type and nature, and applies to the environmental aspects of its activities, products and services that the Organisation determines it can either control or influence considering a life cycle perspective. ISO 14001:2015 does not state specific environmental performance criteria. ISO 14001:2015 can be used in whole or in part to systematically improve environmental management. Claims of conformity to ISO 14001:2015, however, are not acceptable unless all its requirements are incorporated into an Organisation 's environmental management system and fulfilled without exclusion.

Specification for installation, operation and maintenance	BS 6701:2010	If you work in the telecommunications industry, and are responsible for installing, operating or the administration and maintenance of copper or optical fibre cabling or equipment, then this newly-revised standard will be of interest. Conformance to specific aspects of BS 6701 is a requirement of the Wiring Regulations (BS 7671) and is applicable in virtually all premises. In addition, it addresses cabling external to buildings and should be followed by anyone installing cabling. Correctly specified and installed cable management systems ensure that telecommunication cabling performs at its best – so it is important that cable management be considered from the start of a project. In addition to specifying the requirements beyond the scope of the BS EN 50174 series of standards for telecommunications cabling, BS 6701 provides requirements for installing telecommunications equipment. The application of BS 6701 will ensure that equipment is properly set up, which means the customer will be reassured their risk-managed cabling installations work to optimum performance, thus assuring more profitable business practice. As one of the few national standards that are directly linked to the EN 50174 series, BS 6701 could also be used in other countries. It supports all cabling media.	SHOULD	A valid ISO 27001:2013 Certificate is required from a UKAS accredited and registered certification organisation.
ES10.0	EU Code of Conduct	EUCoC	This Code of Conduct has been created in response to the increasing energy consumption in data centres and the need to reduce the related environmental, economic and energy supply security impacts. The aim is to inform and stimulate data centre operators and owners to reduce energy consumption in a cost-effective manner without hampering the mission critical function of data centres. The Code of Conduct aims to achieve this by improving understanding of energy demand within the data centre, raising awareness, and recommending energy efficient best practices and targets. TBD: May be put on the roadmap.	SHOULD	Provide formal confirmation of compliance to requirement
ES11.0	General Data Protection Regulation Data Protection Act 2018	GDPR / DPA 2018	The Guide to the GDPR explains the provisions of the GDPR to help Organisations comply with its requirements. It is for those who have day-to-day responsibility for data protection. The GDPR forms part of the data protection regime in the UK, together with the new Data Protection Act 2018 (DPA 2018). The main provisions of this apply, like the GDPR, from 25 May 2018.	MUST	Provide formal confirmation of compliance to requirement
ES13.0	BS EN 50600-2-1:2014. Building construction (Minimum availability class 3)	BS EN 50600-2-1:2014	The unrestricted access to internet-based information demanded by the information society has led to an exponential growth of both internet traffic and the volume of stored/retrieved data. Data centres are housing and supporting the information technology and network telecommunications equipment for data processing, data storage and data transport. They are required both by network operators (delivering those services to customer premises) and by enterprises within those customer premises. Data centres need to provide modular, scalable and flexible facilities and infrastructures to easily accommodate the rapidly changing requirements of the market. In addition, energy consumption of data centres has become critical both from an environmental point of view (reduction of carbon footprint) and with respect to economical considerations (cost of energy) for the data centre operator. The implementation of data centres varies in terms of: a) purpose (enterprise, Colocation, co-hosting or network operator facilities); b) security level; c) physical size; d) accommodation (mobile, temporary and permanent constructions). The needs of data centres also vary in terms of availability of service, the provision of security and the objectives for energy efficiency. These needs and objectives influence the design of data centres in terms of building construction, power distribution, environmental control and physical security. Effective management and operational information is required to monitor achievement of the defined needs and objectives. This series of European Standards specifies requirements and recommendations to support the various parties involved in the design, planning, procurement, integration, installation, operation and maintenance of facilities and infrastructures within data centres. These parties include: 1) Owners, facility managers, ICT managers, project managers, main contractors; 2) Consultants, architects, building designers and builders, system and installation designers; 3) Suppliers of equipment; 4) Installers, maintainers.	SHOULD	Formal accreditation against BS EN 50600 will not be available until mid 2019 therefore Suppliers MUST be able to provide evidence to demonstrate alignment with the scope and aims of BS EN 50600. Note: Formal accreditation (when available) will become a mandatory requirement as detailed in the standards road map
