Statutory Standards and Frequently Asked Questions
Cardiff does not create a special IR35 code for Data Architect work. The client SDS should name the Cardiff workplace and delivery model. An inside finding on a Cardiff Data Architect brief typically deducts tax at source, while outside IR35 Data Architect work in Cardiff is billed by a PSC. Local pay sits on a regional rate discount versus London, so a higher Cardiff headline rate can still be inside. Commuting into Cardiff does not, by itself, prove substitution or lack of control. Read the Data Architect Cardiff contract for workplace, hours, and equipment clauses.
