How to Read a Broadband Fact Sheet
Decoding the small print: Minimum terms, CPI, and upload speeds.
The Transparency Rules
Thanks to Ofcom regulations, broadband providers can no longer hide the important details in page 50 of a PDF. They must present you with a “Contract Summary” or “Fact Sheet” before you sign up. But it can still look like gobbledygook. Here is how to decode it to make sure you aren’t getting ripped off.
1. “Average” vs “Minimum” Speed
You will see a headline speed, e.g., “900Mbps Average Download Speed.”
The Average: This is the speed that at least 50% of customers receive during peak hours (8pm-10pm). It’s a good guide, but not a promise.
The Minimum Guaranteed Speed: This is the crucial number. It is usually lower (e.g., 450Mbps). If your speed drops below this number and the ISP cannot fix it within 30 days, you have the legal right to exit the contract penalty-free. Make a note of this number!
2. The Price Rise Clause (CPI/RPI)
Look for a section called “Price” or “Your Monthly Bill.” Scan for the words “CPI” (Consumer Prices Index) or “RPI” (Retail Prices Index).
Bad: “Prices may increase by CPI + 3.9% in March/April.” This means your bill WILL go up, potentially by a lot, every year.
Good: “Fixed Price” or “No mid-contract price rises.” This means the price is locked.
3. Upload Speed
This is often hidden away. On a 100Mbps package, the upload might only be 20Mbps. If you work from home or game, check this figure. On CityFibre, you are looking for “Symmetrical” speeds where this number matches the download speed.
4. The “Post-Contract” Price
Often, the price you see is a “Special Offer” for the first 18 or 24 months. The Fact Sheet must state what the price reverts to afterwards. It might jump from £30 to £55. While you can usually switch or re-contract when the time comes, it’s good to know the default “out of contract” price so you don’t get a shock bill in two years.
