Related questions

How is the monthly figure worked out?

Each plan's advertised price and the rises its provider publishes for later in the contract are averaged over the contract's months. An introductory price for the first months only is shown beside the plan and is not counted.

Can I get these where I live?

Which providers reach an address depends on the postcode, and a row says so where its provider's page limits the price to a place. The postcode check on the main UK page shows which plans can apply where you live; the provider's own checker has the final word.
