published on UK Free TV

There are several different types of interference that cause problems. This page deals with the situation where:



There are two main causes of this type of intermittent interference:

Induction interference

Induction interference is caused by mains-powered household devices that contain a large motor, such as:
  • Washing machine;
  • Tumble dryer;
  • Central heating pump or combination boiler;
  • Fridge;
  • Freezer;
  • Power tools (drills, jigsaws etc)
  • Vacuum cleaners;
  • Water pumps;
  • Automatic doors


You can identify if one or more of these devices is causing the Freeview reception problem by powering off the devices.

If one of these devices is causing the problem, then the reception problem can usually be solved by using a mains filter device and use it on the Freeview boxes mains connection.



Such as device is this: <img src="data:image/png;base64,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" class="xico" style="vertical-align:text-bottom" alt="www.maplin.co.uk link icon"> link iconMaplin: 6-Way Flat Screen and HDTV Surge Protector and Mains Filter.

Mobile phone interference

If you keep a mobile phone by your Freeview box or digital television, keep it further away!

This also applies to other transmitters such as baby monitors, video senders, walkie talkies, and portable phones.

Hi Michael,
i have been having intermittent reception problems on all bbc channels for some time. i have complained to the bbc and low and behold the problem was fixed; for a while. now it is as bad and getting worse. i have tried to complain again but cannot find the same complaints site. all i can find is options that ask which programme and what day and time. i know the bbc don't like being complained to from the condescending email i received from them. i might be 70 years old and not technically minded but won't be thought of as an idiot! can you please help me to find the appropriate complaint site? thank you Michael.

shirley cooper: This is, as you say, a reception issue and as such the BBC is not responsible for your own system (aerial, TV, cable etc).

The most common reason for poor reception, and indeed the first thing to check is that you are tuned to the correct transmitter -- the one to which the aerial faces.
