Timloc is offering customers the chance to win £3,000 worth of high street vouchers as part of a competition launching next month.

Thirty golden airbricks will be hidden within packs of terracotta and buff airbricks sold by the building supplies manufacturer, with each golden airbrick equating to £100 worth of retail vouchers.

The competition will run for three months and is to start in July 2015.

Dave Bean, Timloc sales director, said: “With each golden airbrick found, we will give away £100 of vouchers for high street stores, so there will be something for everyone.”
