do I need any certifacates,
Yes all electrical work should generate certificates, Either a minir works certificate or an installation certificate. It the work is notifiable under Part P then these will need submitting and you will also have a completion certificate.
do I need an electrician?,
One does not have to use an electrician if you have the knowledge, however if it requires a completion certificate under Part P then by time you pay the council and hire test equipment likely the electrician route is cheapest option.
and do I need to create a mini ring main,
No the ring main is designed to cover a large area and you are not covering a large area.
You will need some form of protection which could be a fused connection unit or full consumer unit and the cable will need to be correct size. A radial from a 32A supply will normally be 4 mm sq or 6 mm sq according to route. Likely 4 mm in your case.
However RCD protection will be required and how it is wired would depend if the protection is already provided or not.
I would plan out what you intend to do completely before applying to LABC then present them with whole plan as far easier to alter a plan then alter wiring if they don't like what you want to do.
