Supplier application

Application is the first phase of the qualification process. This section will guide you in gathering all the information necessary to fill in the application questionnaire so you can proceed with registration on the IT4Buy suppliers portal.

The first step to becoming a supplier: gather the information to apply


Collect the preliminary information which will allow you to register on the platform.

Who is involved

All new suppliers. The categories involved are set out below:

  • Individual suppliers.
  • Freelance professionals, start-ups and innovative SMEs.
  • Permanent Groupings of Companies (e.g. Stable Consortia, Consortia between Production and Labour Cooperatives, Consortia between Craft Enterprises). Qualification as a Permanent Grouping of Companies requires the positive assessment of the individual suppliers associated and compliance with the provisions of Legislative Decree 50/2016. The permanent grouping must therefore submit its request for qualification together with its own documents as well as those of the individual suppliers associated in reference to the GOODS/WORKS/SERVICES within its remit. There is no qualification process for Temporary Groupings of Companies given their specific duration, which is temporary and occasional.
  • Commercial Operators (Distributors/Wholesalers/Stockists). The qualification of Commercial Operators of goods (including System Integrators) is combined with that of suppliers who produce the goods in question. The Operator must therefore submit its request for qualification together with the documents relating to its company and those of the producer of the goods in question. For qualification as a Commercial Operator of goods produced by companies that are already qualified the request need not be accompanied by annexes relating to the producer of the goods, but the latter must submit a statement accepting it will be excluded from the list of Italgas suppliers if the outcome of the Operator qualification process is positive.

Sustainability Score


Increasing attention to sustainability issues and the need to measure, manage and mitigate the ESG – Environmental, Social and Governance – risks drive us more and more to promote and encourage a type of responsible business. 

For these reasons, in line with the company’s objectives, the Procurement Department is setting up an Assessment process for ESG matters with a view to carrying out a series of ESG audits, for the purpose of the growth and accountability of the Supplier Base. 

A first step towards the responsible improvement of the supply chain is filling in the Sustainability Questionnaire during the application phase. The purpose of the questionnaire is to determine the general and specific level of business sustainability, and to offer a summary overview of the certifications in the various ISO Management Systems. The supplier receives a rating based on the score obtained (“Sustainability Index”). If the rating is lower than the set threshold, the supplier will not be admitted to the subsequent phases of the qualification process. Average-low ratings will be subject to an ESG audit to identify the areas of improvement and monitor them through targeted plans of action in the short and long term. 

The sustainability index is one of the parameters included in the Supplier Rating. The aim is to tighten up the supplier management process so that together we can build an increasingly widespread Culture of Sustainability along the entire value chain.

EU Qualification Systems

The most important activities that are considered as being above threshold pursuant to Italian Legislative Decree 50/2016 (Contracts Code) are managed through the publication of “Qualification Systems” by the European Community, stating the minimum HSEQ, economic-financial and technical-organizational requirements needed by suppliers in order to be entered on the Italgas Vendor List.   

The Qualification Systems are published in the Official Journal. Click here to consult the list.

For other activities considered important in terms of turnover and technological complexity, Italgas has identified specific qualification requirements linked to the distinct characteristics of the Goods Category.

Italgas Vendor List Regulations

The purpose of the Italgas Vendor List Regulations is to indicate the rules and principles by which the Italgas Group Supplier Register is established and managed, and which all our suppliers must observe.

Consult the application manual

Italgas reserves the right to check the supplier’s economic and financial stability on an ongoing basis using an external provider on an online platform, which can be accessed by specialized Italgas analysts who check the economic prerequisites and conduct timely in-depth analyses reported in the context of the Reputational Check. 

Therefore, the supplier will be required to proactively update the documentation and any changes to the corporate structure, any additional certifications obtained and any situations with an impact on its reputation. 

Sustainability requirements

We ask our suppliers to meet important sustainability requirements in order to comply with the Group’s goals and ambitions.
