Whilst mobile networks are being improved in Loughton, the works could cause interference to TV received through an arial such as Freeview, BT, TalkTalk and YouView.

Residents are likely to be affected if they live in an area with weak digital television reception, have a TV signal booster and whose TV aerial is close to a mobile mast.

Symptoms could include intermittent sound, blocky images (pixelation) or loss of TV signal.

Retore TV is offering free support to ensure people can continue to enjoy their TV.

The programme offers additional support for people who are 75 years of age or older, are registered blind or partially sighted or receive any of the following benefits: personal independence payments (PIPs); attendance allowance; constant attendance allowance or War Pensioner’s Mobility Support.

Ben Roome, CEO of Restore TV, said: “If you see new TV interference, we’re on hand to help you resolve the issue.

“We can send a Restore TV filter, free of charge, for you to fit between your aerial lead and TV or set-top box to remove mobile signals and allow you to watch free to view TV as normal.

“Full instructions are included, and we can provide further advice online and by phone if needed.

Cable and satellite TV, such as Sky or Virgin, are not affected.

Any viewers who experience new interference to free to view TV should contact Restore TV on: 0808 13 13 800 or visit their website.
