How many portable toilets per person?

The general UK event industry guideline is 1 portable toilet per 100 guests for events up to 4 hours. For longer events, increase to 1 per 65-80 guests. If alcohol is served, add 30% more units as guests use facilities more frequently.

Do I need disabled toilets at my event?

Yes. Under the Equality Act 2010, you should provide accessible toilet facilities. Best practice is at least 1 disabled unit for events up to 250 guests, with an additional unit per 250 guests after that. These are larger units with handrails and wheelchair access.

What types of portable toilet are available?

Standard chemical toilets are the most common and cheapest. Luxury trailer units have flushing toilets, mirrors, and heating - ideal for weddings. Urinal units for men reduce queues. Eco-friendly composting toilets are available for festival-style events.

How much do portable toilets cost to hire?

Standard portable toilets cost around £80-120 per unit for a weekend hire. Luxury trailer units cost £300-800 depending on size and specification. Prices include delivery, setup, and collection. For multi-day events, add servicing costs of £30-50 per unit per day.

Where should I position portable toilets?

Place toilets at least 20m from food preparation areas and water sources. Position them downwind from the main event area. Ensure firm, level ground for stability. Provide adequate lighting and signage. Keep access paths clear and consider adding hand sanitiser stations nearby.
