Is this using live data?

Yes, where available. The tool calls internal API routes for postcode geography, Ofcom speed benchmarks, provider complaints, technology coverage, and FTTP take-up. If a source is unavailable, the result clearly marks it.

What is real and what is estimated?

Inputs are always your own values. Source badges in the result show whether each dataset was real, estimated, or unavailable for that run.

What is the future readiness card?

It is a catalog-style derived metric that combines FTTP take-up, technology coverage, and local speed context to show whether the area looks ready for stronger fibre adoption.

Why can an alternative still be estimated?

Exact live deal terms for every plan are not always available in one feed, so provider market profiles are used to estimate speed and bill differences.

Should I switch immediately if savings are high?

Use this as a shortlist tool, then confirm contract length, setup fees, and exit charges before making the final switch.

Quick Tips

Jump-start your understanding with these essential tips

The annual savings card is based on your entered bill. If the bill is outdated, the savings estimate will be misleading.

Enter the speed your household actually needs. This prevents overpaying for plans that are faster than your day-to-day use.

Each run shows which parts are real API data and which parts are estimated. Prefer decisions where more sources are marked real.

Step-by-Step Guide

Follow these steps to get the most from this tool

The tool validates your postcode and uses it to load local or regional broadband context. Then it combines that with your current provider, monthly bill, and required speed.

💡 Pro Tips:

•Use the exact provider name in your current contract.
•If your speed target is uncertain, run one low and one high scenario.

The reliability score is split into four parts: uptime and complaints, speed consistency, connection stability, and fault resolution. You can also review Ofcom technology coverage and a future readiness card built from FTTP take-up, local coverage, and speed context.

💡 Pro Tips:

•If complaint data is unavailable, treat ranking differences as lower confidence.
•If multiple alternatives are close, compare contract terms before deciding.

Use the alternatives table to identify likely better plans. After that, confirm current pricing, setup fees, contract length, and exit costs on the provider website.

💡 Pro Tips:

•Export JSON or CSV to keep a decision record.
•Re-run when your provider raises prices.

Advanced Topics

Deep dives for advanced users

When two providers are within a few points, cost and contract terms usually matter more than tiny score differences. Treat the score as decision support, not a guarantee.
