A Co-op member, or happy to join: Your Co-op Broadband & Mobile. Membership is free, the first month costs nothing and a £20 welcome reward follows. The 24-month contract carries no in-contract price rises.

How to choose a broadband deal: six checks
1) Your postcode. Every deal here depends on coverage at your address, so run the checker first.
2) The price after the offer. Look at the monthly cost once any introductory price ends, and whether it can rise during the contract.
3) Contract length. 30 days gives freedom, 12 to 24 months gives lower prices; Grain's 18 months comes with a fixed price.
4) Speed you will use. Full fibre from 250Mbps to 2.5Gbps suits streaming, working from home and big households.
5) Installation and the router. Look for free installation and a free router.
6) The reward and how it is paid. Vouchers and reward cards are claimed from the provider after installation, so read how and when.
Bundling a mobile plan
Your Co-op Broadband & Mobile also sells SIM-only plans on 30-day rolling terms, with a first month free and a £5 to £25 welcome reward depending on the plan. See our best SIM-only deals guide to compare it with the networks.
