I purchased vinyl click laminate from Carpetright. Relatively expensive flooring. Advised at the time from a store that was closing down and was selling off the last of its stock that underlay was not required and that the instructions include advising underlay as a tool to upsell products. The store was closing and the guy had no interest in "upselling underlay" we were told. Floor fitted and a month later commences to come apart. I contacted the company and requested advice and they stated underlay should have been fitted. Then get the stock question did you fit it yourself and that it is my responsibility to check the requirements (I would assume speaking with a staff member with 30 years retail experience with floor coverings", was akin to carrying out diligent checks. Further stated it is not their responsibility. To cut a long story short, they are not interested and it is my fault not carpetright or its staff. Over £1000 worth of flooring now needing lifted and replaced. Wouldn't touch them with a bargepole
