Dimark app support
Dimark is the trade ordering app of Dimark Limited, for business customers in the UK. Businesses use it to apply for a trade account, browse our products, place orders and manage their account.
Applying for a trade account
You can apply in the app. Choose Apply for a trade account, fill in the form, add the documents asked for and sign on the screen. Our office checks every application. If it is approved, you receive an email from our online shop to set up your password, and you can then log in to the app with that email and password.
If you have questions about your application, contact the office with your application reference (it starts with DMA-).
Login help
If you already have an account with our online shop, log in with the same email and password.
If you have forgotten your password, choose "Forgot your password?" on the login screen. If you still cannot log in, contact the office.
App support
For help with the app, including your application, orders, products or technical problems, contact:
Email: info@dimarkltd.co.uk
Telephone: 020 8887 9696
Please describe the problem, and tell us your phone model and the app version (shown in the app under Profile → Account).
Please do not send passwords, identity documents or other sensitive information by ordinary email.
Deleting your account
You can ask us to delete your account in the app:
1. Open the Dimark app.
