Financial Assistance

St Mellons is a Tier Two Grant Assisted Area and Cardiff Council can help to guide businesses looking to start up or locate in the city. Grant aid might not be a key reason for a company choosing a vibrant location like Cardiff, but the availability of a grant can help to reduce the risk of an investment. Cardiff Council and the Welsh Government’s Inward Investment team can discuss suitability and the availability of a grant package which could provide a very competitive offer to qualifying businesses. Further information is available on request.

WCR Space is part of WCR Group Ltd with offices in Caerphilly, just north of Cardiff and Ashford, Kent.
