For every picture of a kitchen porter posted on Instagram or Twitter Winterhalter will make a donation to Hospitality Action.

Stephen Kinkead, managing director of Winterhalter UK, said: "KP day is a way of raising the profile of the amazing work KPs do, day in day out, in a fun way. We've had some amazing pictures down the years, and every contribution raises money for a great cause."

Hospitality Action provides vital support for people who work, or have worked, in the UK's hospitality industry and who find themselves in crisis.

Mark Lewis, chief executive of Hospitality Action, added: "Winterhalter has been a staunch supporter for many years. We're grateful to them for having been picked as the nominated charity for KP Day once again, thanks to them we're able to transform the lives of hospitality employees who have fallen on hard times."

To take part, simply share a picture to @winterhalteruk of your kitchen porters on Instagram or Twitter with the hashtag #kpday. For every photograph, Winterhalter will donate £2.50 to Hospitality Action, up to a maximum of £500.
