FAQ
Common questions
What's the absolute cheapest UK broadband deal?+
As of May 2026, the cheapest fixed-line broadband deals start around £19/mo for slower copper-based packages. Full-fibre starts around £24-£25/mo for the cheapest 100 Mbps tier on Be Fibre or similar altnets.
Is the cheapest broadband always the best value?+
No — beware bait headline rates that bump after 12 months and £40-£100 setup fees. Always check total contract cost, not just the headline monthly. Our broadband comparison page sorts by total cost, not just monthly rate.
