Sorry, but it will and does have a bearing.
Go and have a read about designated standards. Further you'll need to know which directives and regulations were transferred into British law by the withdrawal act.
Untangling ourselves was always going to be something that takes years n years n years, and the transition period only ended 5 minutes ago, it's still not mandatory (for another 6 months) to use the UKCA mark.
It's a nice pipe dream to say 'make everything better now' but I'm afraid that's all it is, and will be for some time.
In the mean time, it's paying my wages, and whilst I really don't enjoy talking shop if I'm not being paid for it you need to understand the processes and potential timelines.
