avrouk.com/images/ul/guide- … ations.pdfMy read of your question boils down to when you would need to be covered under EU regs and when you can use the exemption to operate under Domestic.
Assuming you are the one and only driver any day you do haulage (or out of your 100km radius) you would be under EU regs for the day and also need to take a suitable weekly rest.
Not sure I’d trust or rely upon anything as being current in that avro doc as it’s foreword is by VOSA!!!
Otherwise, agree with your summary.
