You can refer friends and neighbours to join PMP via https://pickmypostcode.com/referrals/ where you'll find your unique referral code.
Copy and paste this into a text, email, on social media, via any form of communication that works for you, and then when people click on this link and register an account it'll be automatically clocked as a referral.
You will receive an additional 1p per day bonus for every day that those people check the site up to 20p per person.
You will however lose any referral bonus accrued if any of those people delete their account. You can earn a maximum of £200 through referrals. (1000 users).
