Frequently Asked Questions
How many toilets are required on a construction site?
Under CDM 2015 regulations, the minimum provision is 1 toilet per 7 workers. If you have separate male and female workers, you may need separate facilities. Additionally, at least 1 accessible unit should be provided if any disabled workers are on site.
How often do construction site toilets need to be serviced?
Typically once per week for standard usage. High-use sites (large crews, summer weather) may require twice-weekly servicing. Your hire contract will specify the service schedule — always confirm this before signing.
What are the CDM 2015 welfare requirements?
CDM 2015 requires: adequate sanitary facilities (toilets and handwashing with hot and cold water), rest facilities (somewhere to sit, eat and shelter), changing facilities if workers need to change into work clothing, and a place to dry wet clothing.
Can I get long-term hire rates?
Yes — most suppliers offer discounted rates for hires of 4 weeks or longer. Some offer fixed monthly rates for ongoing construction projects. Always compare weekly vs monthly rates and ask about extended contract discounts.
What happens if a unit gets damaged on site?
Most hire agreements include a damage waiver or insurance option. Check your contract for liability terms before accepting delivery. Report damage immediately to your supplier — attempting repairs yourself can void the agreement.
