Honda UK has said it will shut down its Swindon factory for six days in April as part of its preparations for any disruption caused post-Brexit.
The Japanese-owned car giant said the move was to ensure it could adjust to “all possible outcomes caused by logistics and border issues”.
The firm said it would help in recovering lost production if shipments of parts were held up at borders.
Honda employs about 3,400 people at its Swindon plant.
In a statement, the company said: “We are planning six non-production days in April 2019. This is to facilitate production recovery activity following any delays at borders on parts.
“These contingency provisions have been put in place to best mitigate the risk of disruption to production operations at the Swindon factory.”
Last year, the senior vice-president of Honda Europe warned that if the UK left the EU without a deal, it would cost his company tens of millions of pounds.
Ian Howells told the BBC that quitting the bloc without an agreement would affect the carmaker’s competitiveness in Europe.
He said the Japanese firm was preparing for a no-deal outcome, but had not discussed relocating its Swindon plant.
The firm builds its Civic model in the UK for the global market.
