GrannyGravy13 Quote [ Our suppliers have given us assurances that there will be little or no disruption to supply chain (these are extremely big multi nationals)] End Quote.
GrannyGravy13, your suppliers are making a rediculas statement in the above. No matter how large they are they do not control the flow of vehicles through the ports and therefore any delays that may occur due to checks having to be carried out due to Brexit.
The situation is in the Road Haulage Industry that many very experienced HGV drivers carrying out Continental operations are stating that they do not wish to do those journeys should Brexit mean they will be sitting in their cabs going nowhere for days on end.
Further to the above, Britain has a shortage of nearly fifty thousand truck drivers according to many estimates, so alternative HGV owner driver or employed drivers will be very difficult to find.
Hauliers based in Europe are also stating that they will not be undertaking journeys to Britain if delays start to occur at the ports. No one makes any money from a truck sat doing nothing, and they will still have twenty-seven other countries in the European Union they can operate in.
Therefore and as stated, for your suppliers to state that "no delays will occur in their supply chain to your business" GrannyGravy13 is totally and absolutely rediculas.
You may get better advice by looking on the Road Haulage Association website, where as we run-up to the 31st of October the latest news will be available.
