How to organise a mill open day

A successful mill open day depends on more than opening the doors. Set the programme first, then build the visitor flow around guided tours, demonstrations, parking and refreshments. Safety checks, permits, insurance and volunteer instructions need to be settled before invitations go out. Use registrations to divide tour groups, collect dietary requirements and estimate drinks, bread and seating. Finish with a weather check, site clean-up and a final check of toilets, signs and access routes.

Tips

Set the date and programme before ordering supplies or sending invitations. Include fixed tour times and demonstrations so you can divide visitors into manageable groups rather than letting everyone arrive at once.
Complete the safety inspection, permit checks and insurance review early. Mark the access route, parking spaces, floor plans and visitor signs at least one week before the open day, then walk the route as a guest would.
Close registrations several days before the event and use the final numbers to assign tour groups, order bakery products and calculate drinks. Ask for dietary requirements during registration, not at the buffet.
Recruit enough volunteers for distinct jobs: welcoming visitors, guiding tours, running demonstrations, serving refreshments, handling payments and checking toilets. Give each person written instructions and a named replacement before the day starts.
Prepare for changing weather by checking the forecast the day before and again on the morning itself. Decide where party tents, tables and chairs will go, and test coffee machines, kettles, extension cords, the payment terminal, microphone and sound amplifier before visitors arrive.

Frequently asked questions

How far in advance should I plan a mill open day?: Start the programme, permit and insurance checks at least 8 weeks before the event. Send invitations once tour times, access arrangements and the main demonstrations are confirmed.
How do I organise guided tours at a mill open day?: Set fixed tour times and divide registrations into groups before the event. Aim to confirm every group at least 3 days in advance, with a volunteer assigned to each tour and clear instructions for the route.
How many volunteers do I need for a mill open day?: Plan at least one volunteer for welcoming and registrations, one for each guided tour, one for demonstrations, two for refreshments and one person covering payments and practical issues. Finalise the rota 1 week before the event.
When should I order food and calculate drinks for a mill open day?: Use the confirmed registration total to place the bakery order and calculate drink stock 3 to 5 days before the event. Pick up the bread products on the day or the previous day, depending on freshness and opening times.
