Airbnb release payment to the Host 24 hours after Guest arrival, and payment then takes a number of working days to clear into Host bank account or whatever other method used to receive.
It's worth taking the time and trouble to peruse the website 'Help'. You will find a lot of useful information.
While you are at it, please also check under Profile Photos. You will need one to begin hosting on Airbnb.
Lastly, if you find that you are not getting many bookings, perhaps reconsider your price of £ 800 - £ 1000 per day. I have no idea of comparative prices for your location, but it's worth checking the competition.
Best Wishes.
