What tools do I need to purchase

Something is creaking when pedalling under load
Would like to remove and clean the chainset but not sure of the tools or method is required.

10mm hex placed in the 10mm hex shaped hole in the middle.
Righty tighty…..lefty loosey.
Then hit it wit a rubber ‘ommer till it come owt.
(then take to a shop for a new bb)

^^^ what he said.

So it’s non serviceable and need to be booked into a bike shop.
What sort of price is this type of bb and the labour cost for the job.
