The company said it had been “assessing how best to prepare for any disruption caused by logistics and border issues following the UK leaving the EU on 29 March 2019”.
Honda revealed that 40% of its components are sourced from the EU and that 35% of its cars are exported there. Honda currently employs around 3,400 people at the factory.
The Japanese firm told Sky News: “To ensure Honda is well placed to adjust to all possible outcomes, we are planing 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, Ian Howells, warned that if the UK left the EU without a deal it would likely cost Honda tens of millions of pounds.
