Support calls should be directed to your AVCS Distributor in the first instance. Where your AVCS Distributor is unable to provide support or assistance please contact UKHO Customers Services:
phone +44 (0) 1823 723366.
Where a vessel is diverted for commercial reasons an order can be raised through your AVCS Distributor. Your AVCS Distributor will receive the permits immediately on placing the order and these can then be forwarded on to you by arrangement with your Distributor.
All AVCS users are supplied with a Certificate, carrying the UKHO crest and Chief Executive’s signature, which certifies that all charts supplied in AVCS are ENCs that conform to the requirements of SOLAS Chapter V.

Emergency Chart Permits
In certain circumstances it may be necessary for a vessel to get access to an AVCS chart at very short notice, for instance if she has to divert her route due to a medical or safety emergency. In these emergency circumstances, individual AVCS Chart Permits can be obtained from the UKHO 24 hours a day, 365 days a year. These Chart Permits can be transmitted direct to the vessel by email wherever possible, by fax, or simply by reading the characters out over the telephone or radio. Each Chart Permit consists of 64 characters.
To obtain an AVCS emergency chart permit please contact UKHO Customer Services, quoting your name and contact details, the vessel name, the User Permit Number of your ECDIS system and the cell number(s) required.
