I've been doing this for a while. If you sign up for a new 'card' (it's all virtual QR cards now) you get 200 'free' points after you buy your first sandwich which are doubled, 200 points for using promo code X-5ZNF1MI, and hooray you have over 500 points for a free sandwich. Then do it with a new card next time.

Hi! This is a special offer from Community Fibre. The referral reward is usually £50 but there is a special offer going now and we will both receive £100 each instead.

You and I will both receive a £100 Amazon voucher if you sign up for Community Fibre Broadband using this link: https://www.communityfibre.co.uk/friends?referral=0GjBLf5h6T

This Company does next-day set up for London post codes, and have never been more happy as have had to wait weeks for previous wifi companies to set up my account. Have communicated with them via email and the replies are within the hour (so far, to my personal experience). Thank you!

There is no way of tracking referrals, but so far I have had a few successful referrals, which I only knew about a month after they signed up via an email with an amazon voucher code.

Use this link for a £50 reward that will be added to your account 30 days after switching:

I have recently switched to igloo energy, who I found to be the cheapest in my area. Customer service has been excellent so far, and prices are a cut below my previous (big 4) provider. Use the link above to sign up and we will both receive a £50 reward credit into our accounts, 30 days after the switch. Cheers!
