About Us

The Radio and Television Investigation Service helps viewers and listeners investigate and, where possible, resolve interference problems affecting their television and radio reception. Although provided by the BBC, the service covers interference to reception of all UK broadcasters. 

The service combines the following elements:

  • A general diagnostic analysis of your installation
  • Specific questions relating to the symptoms you are experiencing 
  • Advice on the potential source of the problem 
  • Guidance on how you may be able to resolve the issue. On occasions this could include an on-site investigation by Ofcom.*

We cannot guarantee a resolution to your problem but will assist as much as possible, and can advise on a range of options you may wish to consider to find the most appropriate solution.

Our Limits

There are limits to the kind of assistance that can be offered. Ofcom will not accept a referral from RTIS or undertake an investigation where:

  • interference only affects equipment using indoor aerials – both radio and television
  • interference only affects LW/MW (AM) services
  • interference only affects non-broadcast services (e.g. alarms, portable telephones, WiFi systems, Amateur Radio users)
  • interference only affects non-domestic Radio and Television services, e.g. Shortwave radio services
  • the householder has failed to provide sufficient information in response to specific questions.
