Analysis

The data below was collected from responses to the six questions our mystery shoppers asked 114 aerial installers across Wales.

Consumer Focus Wales Chair Viv Sugar said: “Anyone relying on aerial installers risks getting a fuzzy picture on Digital Switchover. There are some excellent installers – but too many who are failing to give consumers all the information they need.

“We were particularly shocked by answers on how to check your reception, where nearly half failed to answer correctly.”

Responses to the six questions have been judged correct or incorrect by Consumer Focus Wales staff, based on template answers provided by Digital UK. In a small number of cases the question has not been answered, or been so ambiguous, we were unable to categorise. These have been put in a third category.

That data – and a breakdown by area – is available on this website.

Question 1: I'm ringing on behalf of my mum. She's worried about the digital switchover. When does this happen in her area?

Question 2: If she wants her TV to work after the switchover, will she need a new aerial?

Question 3: She gets a good analogue picture now. Will she still need to get a new aerial?

Question 4: Is there any way I can check if she will need a new aerial?

Question 5: How much would it cost to have a new aerial fitted?

Question 6: Are you a member of a trade association or approved in any way?
