Nuisance phone calls 'offer home improvements'
Nuisance phone calls are increasingly related to offers of home improvement work, although PPI remains the most common subject, the regulator has said.24 May 2014
The proportion of unsolicited calls that are about payment protection insurance dropped from 22% last year to 13% in 2014, Ofcom found.
But the proportion of calls about loft insulation and solar panels rose.
The regulator added that some nuisance callers were hiding their identity by using "number spoofing".
This tactic means that the number which displays on the recipient's phone is either a false number, or uses the number - without consent - of a legitimate business.
