The questions that separate good companies from mediocre ones
Not all portable toilet hire companies deliver the same experience. Some arrive on time with clean, well-maintained units and service them reliably for the duration of the hire. Others deliver tired equipment late, service it reluctantly, and become difficult to reach when something goes wrong.
The difference between these outcomes is rarely luck. It is determined by the questions you ask before you book — and the quality of the answers you receive.
Here are the questions that matter, why they matter, and what good answers sound like.
1. What is the total cost including delivery, servicing, and collection?
Not the weekly rate. The total. Some companies quote a low weekly rate and then add delivery charges, collection charges, servicing fees, and fuel surcharges on top. The final invoice bears little resemblance to the original quote.
Ask for the all-inclusive figure. A transparent company will give you a number that covers everything — delivery, the hire period, servicing, collection — with only VAT to add. If the answer involves caveats, qualifications, or references to a separate charges schedule, treat it as a warning sign.
2. Is servicing included in the price?
For construction site hires, weekly servicing should be included in the weekly rate as standard. It should not be an add-on, an optional extra, or a separate line item. Servicing is as fundamental to a portable toilet hire as fuel is to a vehicle hire — without it, the product does not function.
For event hires, the unit should arrive clean and fully stocked. Servicing during the event should be discussed if the event spans multiple days.
Ask explicitly: is weekly servicing included in the price you have quoted, or is it additional? If additional, ask for the total cost including servicing before comparing quotes.
3. How old is your fleet?
The age of a hire company's fleet tells you a great deal about their standards and their investment in the business. Units more than eight to ten years old will show their age — faded plastic, stiff locks, worn floors, and a general appearance that communicates neglect regardless of how well they are cleaned.
A company that regularly replaces its fleet cares about presentation, reliability, and customer experience. A company running units from 2012 has made a different set of decisions.
You are unlikely to get a specific age for the exact unit you will receive, but a company that invests in its fleet will answer this question confidently. One that deflects or becomes vague probably knows the answer is not flattering.
4. Do you log your service visits?
Service documentation matters for two reasons: compliance and accountability.
On construction sites, HSE inspectors can request evidence that welfare facilities are being maintained. A documented service log — with dates, times, technician names, and services performed — provides that evidence instantly. Without it, you are relying on memory and goodwill.
Beyond compliance, a company that logs its visits takes servicing seriously. Logging requires systems, discipline, and a commitment to transparency. A company that does not log visits may be cutting corners on the servicing itself.
Ask: do you document every service visit, and can I access those records? A good company will say yes without hesitation.
5. What chemicals do you use?
The chemical treatment in a portable toilet waste tank serves two functions: odour control and waste breakdown. Modern formulations are effective, lower in toxicity, and better for the environment than older products. They are also more expensive.
A company using modern, reduced-toxicity chemicals has made a conscious choice to invest in better products. A company using the cheapest available option has made a different choice — and the difference is noticeable in odour control, environmental impact, and the overall experience for users.
This question also tests expertise. A company that can explain its chemical choice confidently and knowledgeably is a company that understands the technical aspects of its service.
6. Can you provide accessible units?
Every public event requires at least one accessible portable toilet — a larger unit with ramp access, handrails, and sufficient internal space for wheelchair users. If a hire company cannot provide accessible units, their fleet is limited and their understanding of event requirements may be too.
On construction sites, accessible provision may be required depending on the workforce composition and the site conditions.
Ask about accessibility as part of the initial enquiry. A company with a comprehensive fleet will offer accessible units at the same rate as standard ones.
7. What is your delivery window?
A company that can only deliver between seven in the morning and five in the afternoon on weekdays will not suit a Saturday wedding or a Sunday event setup. Ask about delivery flexibility — early morning, evening, and weekend delivery may be available but often at different rates or with limited availability.
For construction sites, weekday delivery is usually sufficient. For events, the delivery window is critical to your setup timeline. Confirm the specific delivery time, not just the day.
8. What happens if a unit is damaged during the hire?
Understanding the liability terms before you sign prevents unpleasant surprises. Normal wear and tear — scuffs, minor marks, the general effects of being on a construction site or at an event — should be expected and not charged for.
Wilful damage, vandalism, and theft are legitimately your responsibility. But the boundary between normal wear and chargeable damage should be clearly defined. Ask for the damage policy in writing.
9. Do you carry public liability insurance?
This is non-negotiable. Any company operating without public liability insurance is a risk to you, your site, your event, and your own insurance position. The question should be answered immediately and affirmatively. If it is not, walk away.
Some clients also request employer's liability insurance documentation and waste carrier licence details. A professional company will provide all of these on request without hesitation.
10. Can you provide references or examples of similar work?
A company that has successfully delivered portable toilet provision for events, construction sites, or projects similar to yours should be able to point you towards satisfied clients. Not necessarily by name — confidentiality may apply — but in terms of scale, type, and outcome.
A confident company will welcome this question. A company that hesitates, deflects, or cannot offer any reference point is telling you something about the depth of their experience.
What the answers tell you collectively
Individually, each question probes a specific aspect of the service. Collectively, the answers paint a picture of the company's standards, investment, transparency, and professionalism.
A company that answers every question directly, knowledgeably, and without evasion is a company that takes its service seriously. A company that stumbles on basic questions about pricing, servicing, fleet age, or insurance is likely to stumble on the service itself.
The ten minutes you spend asking these questions before booking will save you considerably more time, money, and frustration than booking blind on the cheapest quote.
