Share Incentive Plan (SIP)

SIP is a great way for you to invest with National Grid for your future and gain from the success you help create.


You control how much you invest each month. This can be between £10 and £150 (or up to 10% of your gross monthly salary, whichever is lower). This amount will be deducted prior to income tax and National Insurance contributions (NICs).

How does the SIP work?
