After you choose the property, the checker shows an Ofcom predicted speed band. The words on that result have a specific meaning, and a limit.
The three labels
Basic is the band used where full fibre is not the predicted product. Superfast is the band for the shared product up to 80 Mbps. Ultrafast is the band for full fibre, including symmetrical full fibre.
The checker can also name a network that might deliver that speed, such as Openreach or CityFibre. That sentence is a possibility. It is not an order.
What it is not
The prediction does not confirm that the product is available, and it does not reserve an install date. Broadbent Network still confirms the network before install.
If there is no prediction, the postcode can still be taken forward. The full fibre, Superfast, Standard, and leased line pages are the places to choose a product while that confirmation is made.
