So I had my first session today:
Squat - 50kg - 5 5 5
Bench - 40kg - 5 5 5
Deadlift - 70kg - 5 5 5
I'll be increasing all lifts by 2.5kg per session and deadlifts 5kg session to begin with. Luckily my gym also has 0.5kg plates so I'll be able to micro load the bench and press when I get to that stage.
