What is slamming?

man looking at billSlamming is an extreme form of mis-selling when your telephone/broadband services are switched - or attempted to be switched - without your knowledge and/or consent.

Often, the first you may know about it is when you receive a bill from a new company out of the blue.

Slamming is unacceptable and Ofcom has introduced tough rules to clamp down on this problem.

Telecoms firms found breaching our rules can face fines of up to 10 per cent of their turnover.

What to do if you’re being ‘slammed’

  • Contact your current provider and get them to cancel the unwanted move.
  • If the service has already transferred, ask your original provider to transfer you back to them.
  • If you’re aware of the ‘new’ company involved and want to take the matter further, you should follow their official complaints procedure and make a complaint to Ofcom.
