How Long Does It Take?
Most businesses in Cardiff can be fully licensed and operational within 4 to 12 weeks, depending on the business type. Simple home-based businesses can often complete the process in 2 to 4 weeks, while restaurants, bars, and businesses requiring inspections typically take 8 to 12 weeks.
The dependency chain matters — some permits can't be applied for until others are in place. Getting the order wrong means delays and wasted time.
