Welcome to the Supplier Ethics Requirements page. At National Grid, Doing the Right Thing is one of our core principles under our Framework for Responsible Business.

All suppliers are subject to the Supplier Code of Conduct.

Ethics requirements and informational documents

National Grid expects all of its suppliers to comply with its Global Anti-Fraud and Bribery policy.

National Grid expects all of its suppliers to execute a Supplier Ethics Certification Statement. Through this certification statement, you are confirming that you have read and understand the Global Supplier Code of Conduct and that you will communicate same to all of your employees and any subcontractors that you retain on behalf of National Grid. This certification statement needs to be signed prior to performing any work for National Grid.

New York Direct Payment Permits

National Grid USA Service Company and all other subsidiaries as listed below operating in the State of New York have authorization to pay sales and use tax directly to the State of New York for purchases of taxable goods and services.

If you are a construction contractor performing a capital improvement, please be aware that the Direct Payment Permit does not exempt your company from paying sales tax on materials you purchase for a National Grid project.  In all jurisdictions in which we operate (except New Hampshire) the construction contractor is deemed to be the end user on all materials, equipment and tools and must pay the sales tax accordingly. Construction Contractors who are making permanent capital improvements to National Grid facilities or infrastructure may complete the New York ST-124 Certificate of Capital Improvement form and have it signed by an authorized National Grid representative to provide evidence there is no requirement to collect Sales and Use Tax from National Grid. Contractors performing repair and maintenance work (i.e., work that does not qualify as “capital improvement”) can rely on the Direct Pay Permit to provide evidence of no requirement to collect Sales and Use Tax from National Grid.  Also, for all Projects in the State of New York, please consult your tax advisor to identify any exemption opportunities for your scope of work/scope of supply under the New York Form ST-120 Exempt Use Certificate.
