What advice is being issued to keep people safe?

The Builth Wells Event Safety Group is urging visitors to the Royal Welsh Show to take care in the heat by following these tips:

  • Drink plenty of water and avoid excess alcohol
  • Try to keep out of the sun between 11am to 3pm
  • Walk in the shade, apply sunscreen regularly and wear a wide-brimmed hat

The safety group is also warning visitors not to try cooling off in nearby rivers as this could be dangerous and fatal.


The group, which was formed in 2017 and led by Powys County Council, is responsible for reducing public risk and improve the safety of those in and around Builth Wells during the period of Royal Welsh Show.

Cllr Richard Church, Powys County Council’s cabinet member for a safer Powys, said: “The main health risks posed by extreme heat are dehydration so it is important that visitors do everything that they can to take care in the heat.

“If visitors follow our tips, it will help the to take care in the sun but they will also be able to enjoy their time at the Royal Welsh Show safely.

“It’s also important that visitors avoid the temptation of cooling down in nearby rivers, this could endanger lives and could be fatal.”
