  • How are price rises calculated?

    Some providers set annual price rises to cover predicted changes in service costs. This is usually linked to inflation, but from January 2025 they have to tell you the exact amount upfront.

    In our breakdown, we've assumed your first bill will be next month, and your billing date falls after the date any price rises come into place.
