Hi, If I use the availability checker and just enter my postcode and house number (but don't log on to my account) and I already have BT broadband will it just show me updgrades or will it tell me I already have their broadband?
If you are not logged into your account the website will not know you are a customer. Will just show what is available at your address.
using post code in availability checker gives least reliable results - address is better and phone number is even better
the checker will show what is available to you even if you have BT broadband https://www.broadbandchecker.btwholesale.com/#/ADSL
