Email supposedly from Ofgem

I have just received as email, supposedly from Ofgem. The text goes as follows:

Dear M0nica
Starting today the Government has announced an energy bill rebate scheme

This includes:
A £200 discount on their energy bill this Autumn for domestic electricity customers.

A £500 non-repayable Council Tax Rebate payment for all households that are liable for Council Tax.

How do I apply for energy bill rebate?

You can get your rebate via Ofgem portal by clicking the button below:

Claim your rebate now

Setup a direct debit: If you have already received your £500 rebate, you are not required to complete this form.

You have to apply for energy bill rebate before September 2020

It has the Ofgem logo, and looks quite genuine, but, any emails to or from Ofgem always end @ofgem.gov.uk. and this does not.

So forewarned is forearmed. If you receive this email delete it and do not respond.
