Statutory Standards and Frequently Asked Questions
A Interaction Designer contract based in Cardiff is still assessed on facts, not postcode. Status paperwork should reflect Cardiff attendance, hybrid days, and substitution. Inside IR35 Interaction Designer pay in Cardiff is usually umbrella or PAYE, while an outside SDS lets the Cardiff contractor invoice through a limited company. Advertised Cardiff rates follow a regional rate discount versus London, so city uplifts do not imply an outside finding. Travel between home and a Cardiff office is rarely a substitute right. Check Cardiff on-site expectations for this Interaction Designer before you treat the SDS as settled.
