BT Stop Callers

BT has a range of services to help you block unwanted callers.

Apart from annoying friends and relatives, most of these calls may be from cold callers i.e. marketing and sales calls from companies you have never dealt with.

There are also the scam callers pretending to be from an organisation you may deal with e.g. claiming to be from BT checking on your line and asking you to confirm your details first.

There are malicious callers and there are time wasters.

Telephone Preference Service

First, you should also ask the company to stop calling you and remove you from their calling list.

If that doesn’t work then register with the Telephone Preference Service. Once registered then you should only receive Marketing calls from companies you have agreed can contact you.

Of course, criminals don’t obey these rules.

You can register with the Telephone Preference Service by signing up for BT Privacy at Home at We also offer Caller Display which allows you to see the number of the person who’s calling. BT Privacy at Home and Caller Display are both free. You can sign up to them at

Scam calls

These are commonly made by scammers pretending to be from BT.

They may ask you for personal information or want access to your computer. Don’t be fooled, this is fraud.
