The tool directs consumers to the relevant regulator’s complaint form in seconds in a bid to make it easier to register their frustration with nuisance calls and texts.

This will then give regulators the information they need to take enforcement action against companies found breaking the rules.

A report by the consumer rights campaigners found that less than a fifth of Brits officially make a complaint.

This is despite the fact that within one month 85% of people received a nuisance call on their landline.

Around four in ten people complain about nuisance calls and texts to family and friends.

Of those who do officially complain, eight in 10 said it’s important to go on the record so authorities can do more about these calls.

The research revealed that of those who haven’t officially complained, the main reasons are they often don’t know who to complain to (31%), they say complaining won’t do any good (40%), or they don’t think the calls will reduce even if they do complain (43%).

Six in 10 people said they would be more likely to complain officially if there was an easy way to report calls as soon as they received them.

Richard Lloyd, Which? executive director, said: “Consumers are completely fed up with nuisance calls but often don’t know who to complain to, or they think nothing will happen if they do. Our new complaints tool will take the confusion and hassle away and helps people register their frustration with unwanted calls.

“If more consumers complain it will send a clear message that more needs to be done to stop unwanted calls and texts. We urgently need to see a new approach, new laws and new technology to tackle the menace of nuisance calls and texts.”

Last month Which? called on the Government to step in to strengthen the law on consent and the use of personal data, and to give regulators more powers to enforce the law.

Consumers who want to use the tool can do so here.
