Yes it is common to have a seperate 30A/32A ring final circuit for a kitchen due to the modern appliance loads involved. What you said in your first Q would be fine, just remember all conductor joints must be left accessible.
The oven will need to be on its own circuit, the cable calc for that is a little involved as there isn't a standard cable size or breaker rating for an oven. Give me the ovens wattage and I'll do an ad hoc calc to give you an idea of what may be needed.
As for the hob, again what is the power/wattage rating? Don't just assume 45A breaker rating as there isn't a one size fits all, circuit protection must be carefuly selected.
As the other guys said there are no laws to stop homeowners from doing DIY electric works, however the work must be verified.
