'How Do I Get A Booker Account?
Booker is a trade only wholesaler and is not open to the general public. If you are a customer in one of our branches you can set up your online account where you are able to view your recent purchases, and access and download your invoice summary detail, albeit you will be unable to place any orders until this has been agreed with your local branch.
If you do not yet have a Booker account and would like one you can click here to select your local Booker branch and register to be a Booker customer. Once you have your customer number you will need to take two proofs of business to your local branch so that they can discuss your individual requirements with you and set up your account.
You will not be able to order online until you have registered for an online account and agreed collection or delivery arrangements with the Branch Manager.'
