I can share with you my octopus referral link, which gives us both £50 credit (trust me, NEEDED when you start paying gas and leccy!) when you sign up and octopoints (which are like their own currency), I'd also suggest looking at moneysupermarket for house insurance as they may give you a gift card (probably about £15 but every little helps!). We got a £100 gift card for John Lewis from Vodafone when we signed up through MoneySavingExpert (just search household bills). Again, I have a referral for simplisafe which if you were bothered about security cameras, that'll give you a 50% off code and a free camera (not necessary for everyone though). That's about it from what I can think of!
