Where to insert the referral link?

Hi I just sign up with Bulb but I could not find where to insert the referral link that I have to get the £50 discount?
Any idea how to fix it?

Hi @Salvo the referral scheme is a website link that takes you to a sign-up page. As long as you sign up through this page that referral will be applied automatically on your switch.

If you intended to use a referral but forgot to use it drop us an email at help@bulb.co.uk explaining, with the intended referral, and we’ll see what we can do.

Ok thanks.
I’ll email explaining.
