Why are total and effective costs shown?

We show the provider’s advertised monthly price alongside any stated upfront cost and the contract total, so it is easier to compare the terms.

Does DealPriceCheck cover the whole UK market?

No. We compare selected providers and do not claim whole-of-market coverage.
