How will at800 let me know if my Freeview may be affected?
We identify homes potentially at risk of experiencing interference with their Freeview service and write to them before a nearby 4G at 800 MHz mast is activated.
Where and when 4G at 800 MHz is activated depends on the rollout plans of the mobile operators and we are unable to share these specific details.
Please be aware that the majority of viewers who receive a postcard from us will not experience any TV interference caused by 4G at 800 MHz – we expect fewer than 1% of households to experience TV interference.
To find out where we have mailed postcards, please enter your postcode into our postcode look up. If we haven’t mailed postcards to your area, then any interference to Freeview is unlikely to currently be due to 4G at 800 MHz. Please try our online diagnostic tool or visit our page on other possible causes of interference. Or call us on 0808 13 13 800 – calls from UK landlines and mobiles are free. Alternatively, you can email us.
For advice about your Freeview service, including retuning – call the Freeview Advice Line on 03456 505050. See website for opening times and call charges.
