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?
1.

You control how much you want to invest each month. This can be between £10 and £150 each month.
2.

Deductions will then be taken from your gross pay as soon as they can be applied to your payroll.
3.

Each month Equiniti will use your contribution to buy National Grid shares free of any dealing charges.
4.

You will need to leave your Partnership shares in the SIP for five years to keep the full income tax and NIC savings.
