Your estimate
This is an estimate only. Check your contract summary and provider notification. Legacy inflation figures: CPI 3.0% (12 months to January 2026, ONS); RPI 3.8% (12 months to January 2026, ONS). Source: ONS Consumer price inflation, UK: January 2026. No data leaves your browser.
How this calculator works
We detect your track from your contract start date. Deals from 17 January 2025 use the fixed pounds-and-pence rise for your provider. Older deals use CPI + provider margin (BT/Plusnet 6.9%, TalkTalk 6.7% for April 2026) or RPI (Virgin Media 3.8%) using the January 2026 ONS prints. We then estimate total cost over your remaining contract months including the rise.
