Hi. I'm Type 2...so it may differ a bit..but hopefully one reply here will trigger others with direct Type 1 experience.
My first appointment was actually after I had been diagnosed in hospital following a transplant (the steroid treatment caused the diabetes)...and I saw the diabetes team next day. I am presuming you have already been diagnosed and that you are aware of your HbA1c level (ie. the blood sugar level average over the preceding 3 months)...you were probably given this when diagnosed. At your first appointment I would expect you to have your finger pricked to see what the level is at that moment (but they may not do that), blood pressure and weight check, urine sample (which you may have been asked to bring along). They may also check your feet. They should ask about your health generally and about your eating habits.The main objective is to chat with you, discuss insulin and explain your management plan, so you are comfortable with it. Diet will also be discussed and certain food recommended. Bear in mind that not everybody agrees with what the NHS considers a healthy diet. Ask about cutting carbohydrates and see what is said. It should be helpful. Don't hesitate to ask whatever. It's basically to get to now you, to reassure you so you know what you are doing. Come back onto the site afterwards and discuss it. You should survive it ok.
