For payment via invoice please provide us with your contact details, company name, the appropriate billing address for the invoice, email address for the invoice to be sent to and any purchase order number that needs to appear on the invoice. We will then prepare and dispatch an invoice to you based on these details. Once the invoice has been paid then we will send out a coupon code for use (normally within 24 hours) to allow delegate(s) access to the course(s).

We will plant 10 trees for every delegate who enrolls, or is enrolled, on this course.

We are committed to taking action on climate change. We record how many delegates are enrolled for each of our courses and plant the stated number of trees through our partner organisation Ecologi. Reforestation is widely understood as a major natural climate solution. From an ecological point of view we're only just grasping the cost of what life is like without trees. The reforestation projects we fund aren't certified as carbon offsets. The carbon emissions they will sequester will happen in the future.
