The Department for International Trade (DIT) recommend that concerned UK companies trading with Ukraine and Russia contact the Export Support Service (ESS) on 0300-303-8955. The ESS helpline hours are being extended between now and the end of the weekend, from 08:00 – 22:00 Thursday-Sunday inclusive. DIT will review this today to examine the case for out of hours provision.
Alternatively, companies can access the ESS landing page which also features a dedicated link for Ukraine and Russia enquiries.
