The owner of a building company on Anglesey has blasted TV shows that sell Wales’ coast as the perfect place to retire, without making any mention of their language and culture.

Oswyn Williams of Glyndwr Services said that people from the island had had a “bellyful” of TV shows such as ITV’s Robson Green’s Coastal Lives which was broadcast Tuesday night.

In July the show’s production company, Shiver, sent out a press release looking for “families and retired couples that are moving to the coast to start a new life” to be featured on the show.

“This time the new series will be incorporating a property element,” it said.

Oswyn Williams said that he was unhappy that the presenter did not interview a single Welsh speaker on Anglesey and did not refer once to the existence of the Welsh language.

He told Golwg360 that the shows were partly responsible for the hike in house prices that was driving young people from the island.

Homes in Aberffraw now cost £200,000, compared to £50,000 a decade ago, and that homes in Rhosneigr were selling for £600,000, he said.

“These programmes don’t help at all,” he said. “They show what a nice place it is and people flock here to live.

“The unique way of life of the Welsh-speaking inhabitants is never portrayed. Anglesey is a very Welsh place and that should be a key part of the show,” he said.

“If you go to Aberffraw in the winter, the homes are empty. There’s no school. The people who used to live there have moved away.

“They can’t afford to buy the homes. People go there and they pay silly money.”
