Will BT’s blacklist stop nuisance calls before your phone rings?

Phones hanging

In the latest win for our Calling Time on Nuisance Calls campaign, BT is launching a free service to block nuisance calls before they even get to you.

BT’s new nuisance call blocking service is set to launch later this year, and follows similar commitments previously announced by TalkTalk.

BT blocks nuisance calls

The phone provider says it will harness ‘huge computer power’ to analyse and monitor calls to its 10 million customers, with any rogue numbers (generally those that make a huge volume of calls) being added to a ‘blacklist’. Incoming calls coming from these numbers will then be diverted to a junk voice box.

This blacklist will also be expanded if lots of BT’s customers identify unwanted numbers they want to divert.

BT estimates that this will block up to 25 million unwanted calls each and every week.

You’ll also be able to divert unwanted calls to your own personal ‘blacklist’, adding individual unwanted numbers and nominating whole categories of calls you want to avoid, such as international calls or withheld numbers. BT will then prevent these types of calls from reaching your home.

More action against nuisance calls

This is a big step in the right direction for millions of BT customers, but it’s not the end of nuisance calls.


Our campaign, which now has more than 300,000 supporters, has prompted lots of action from the Government, regulators and now technology companies, but there’s still more to do. We need to see more action taken by the industry and the Government to reduce the anxiety caused by unsolicited calls.

Are you happy to see BT bringing in a way to block nuisance calls even before the phone rings? Do you want other companies to follow suit?

Updated 17 January 2017: BT launches call blocking service

BT has launched its new ‘Call Protect’ service, which aims to block up to 30 million nuisance calls a week.

If you’re a BT customer you’ll be able to opt into the service for free. The service will divert nuisance calls before they even reach your home, unlike the call blocking devices you can buy separately.

Vickie Sheriff, our Director of Campaigns and Communications, said:

‘We have long campaigned for tougher action to tackle this problem and it’s encouraging to see new technology being rolled out as part of the solution.

‘Now it needs to deliver results for the millions of people harassed every day by nuisance calls, and we expect other companies to follow suit with their own solutions.’

If you’re with BT, would you opt in to its new nuisance call blocking service? Do you, like 100% of 3,800 voters, want other telecoms providers to follow suit?
