900 people signed a petition against plans for a new Tesco Express store on the site of an old filling station in Trethomas. The store would become the fourth Tesco store within approximately a five mile radius -Tesco has a store in the centre of Caerphilly and a Tesco Express on the outskirts in Pwllypant. Around 100 people attended a public meeting in August 2008 to discuss the proposal. Concerns focused on the expected increase in traffic and impact on small shops in the village. Despite the level of objections Caerphilly County Borough Council approved the application.
