Nuisance calls

Ofcom’s regular research into nuisance calls measures the frequency of nuisance calls UK consumers receive on their home landline phone. We gather ‘real time’ data about these types of calls including date, time and duration of any nuisance calls, and a full description of the experience i.e. the company/person calling, what the call was about, and whether the caller’s telephone number was identifiable.

Ofcom monitors consumer experience of nuisance calls via its Consumer Complaints omnibus study. A nationally representative sample of UK landline users are asked about their personal experience of nuisance calls on their home landline phone ‘in the last four weeks’. Fieldwork is carried out bi-monthly to allow Ofcom to monitor any seasonal changes.
