Statutory Standards and Frequently Asked Questions
Birmingham does not create a special IR35 code for Aerospace work. The client SDS should name the Birmingham workplace and delivery model. An inside finding on a Birmingham Aerospace brief typically deducts tax at source, while outside IR35 Aerospace work in Birmingham is billed by a PSC. Local pay sits on major-city rate parity, so a higher Birmingham headline rate can still be inside. Commuting into Birmingham does not, by itself, prove substitution or lack of control.
