10 Things to Check Before Hiring a Portable Toilet

A Practical Checklist Before You Hire

Hiring a portable toilet is not complicated, but getting the details right upfront prevents problems, unexpected costs, and awkward conversations later. Whether you are booking for a construction site, a private event, or an emergency, these ten checks will ensure the hire goes smoothly.

1. Confirm What Is Included in the Price

The most common source of frustration in portable toilet hire is a final invoice that does not match the initial quote. Before you book, establish exactly what the price includes.

A good hire company will include the following in a single quoted price:

• Delivery to your site
• Collection at the end of the hire period
• The hire itself for the agreed duration
• Weekly servicing for long-term hires
• Waste disposal at a licensed facility

If any of these are listed as extras or not mentioned at all, ask. The cheapest quote is rarely the cheapest once all the additional charges are added.

2. Check the Ground Where the Unit Will Sit

A portable toilet needs firm, level ground. Walk out to where you plan to place it and assess the surface honestly.

• Concrete, tarmac, or compacted gravel: ideal
• Firm, flat grass: acceptable, particularly in dry weather
• Soft soil, slopes, or areas prone to waterlogging: problematic

If the ground is questionable, you may need to lay boards or adjust the position. It is far easier to sort this out before delivery than to ask the driver to improvise on arrival.

3. Measure the Access Route

The delivery vehicle — typically a flatbed truck or large van with a trailer — needs to reach the placement area or get within about thirty metres of it. Check the access route for:

• Width restrictions (narrow lanes, gateposts, parked cars)
• Height restrictions (low bridges, overhanging trees)
• Weight restrictions (weak bridges, residential road limits)
• Turning space at the delivery point

If access is difficult, tell the hire company when you book. They may be able to use a smaller vehicle or suggest an alternative placement that avoids the problem.

4. Count the Users and Calculate the Number of Units

The number of portable toilets you need depends on how many people will use them and for how long.

Construction sites

• One toilet per seven workers is the standard ratio
• Add an accessible unit if required by your site welfare plan

Events

• One toilet per 100 female attendees
• One per 150 male attendees or one urinal per 150
• Increase by 20 to 30 percent for events longer than six hours
• Increase by a further 25 percent if alcohol is served
• At least one accessible unit per event

Underestimating is the most common mistake. If the numbers are borderline, round up. An extra unit costs far less than the reputational damage of inadequate facilities.

5. Confirm the Hire Period

Clarify exactly when the hire starts and ends. Most companies count from the delivery date to the collection date, regardless of when you actually use the unit. If you need a toilet for a Saturday event but it is delivered on Friday, you may be paying for two or three days rather than one.

Ask whether there is a minimum hire period. Many companies have a minimum of one week for standard hires and shorter minimums for events. Understanding this prevents billing surprises.

6. Ask About the Servicing Schedule

For any hire longer than a week, regular servicing is essential. Confirm:

• How often servicing takes place (weekly is standard)
• What the service visit includes (emptying, cleaning, restocking, chemical treatment)
• Whether servicing is included in the hire price or charged separately
• Whether you will receive confirmation that servicing has been completed

A company that cannot clearly describe its servicing process is a company that does not have a proper servicing process. That matters.

7. Check the Company's Licensing and Insurance

Two documents matter:

• Waste carrier licence: Required by law for any company transporting portable toilet waste. Ask for the licence number and verify it on the Environment Agency's public register.
• Public liability insurance: Essential protection in case the unit causes damage or injury on your site. Ask for a copy of the certificate.

A company that cannot produce either document immediately is not one you should hire from.

8. Inspect the Unit on Delivery (or Ask for Photos)

When the unit arrives, check it before the driver leaves. It should be:

• Clean inside and out
• Free from damage, cracks, and staining
• Fully stocked with toilet paper and hand sanitiser
• Equipped with a working lock
• Properly ventilated

If you are not on site for delivery, ask the hire company to send photos confirming the unit's condition. This protects both parties and sets a clear baseline for end-of-hire inspection.

9. Understand the Company's Policy on Damage and Misuse

Portable toilets on construction sites and at events sometimes receive rough treatment. Understand in advance what constitutes normal wear and what triggers additional charges.

Common causes of extra charges:

• Physical damage to the unit (dents, broken locks, cracked panels)
• Prohibited items in the waste tank (nappies, wet wipes, building materials)
• Excessive contamination requiring specialist cleaning
• Units that have been moved without the hire company's knowledge

Most of these are preventable. Brief your team or event staff on proper use and you will avoid surprises at the end of the hire.

10. Know How to Contact the Company During the Hire

Once the unit is on site, you need a point of contact for any issues that arise — a missed service visit, a damaged lock, a request for an additional unit, or a change to the collection date.

Confirm:

• A phone number that is answered during working hours
• How to report urgent issues outside normal hours
• Who your main contact is within the company
• How quickly the company can respond to a problem

Good communication throughout the hire period prevents small issues from becoming big problems. A responsive hire company is worth its weight in clean, well-serviced portable toilets.

Before You Pick Up the Phone

Run through this checklist before you call. Having the answers to these questions ready — site access details, ground conditions, number of users, hire dates — means the hire company can give you an accurate quote immediately rather than a vague estimate that changes later.

Preparation takes ten minutes. It saves hours of hassle.
