Construction site toilet hire West Midlands.

Expert guidance on portable toilets,welfare facilities, servicing and sanitation site planning for construction projects

If you’re responsible for a construction site, providing suitable welfare facilities is something you should be factoring into your project early on. You will need to consider:

  • How many people will be on site.
  • Where they will be working.
  • How accessible the facilities are.
  • How often they need servicing.
  • How your site layout will change as construction progresses.

For more than 30 years, D-Tox has provided construction site toilet hire and effluent waste management across the WestMidlands. We work with construction companies, contractors and site managers on projects ranging from small building works through to large developments.

We can guide you through what you need to consider when planning construction-site toilet provision, including *HSE guidelines (CDM requirements), toilet numbers, positioning, servicing, costs and practical lessons we’ve learned from years of working on construction sites.

Construction sIite toilet requirements : Q&A

How many toilets do I need?
See our full guide below on calculating the right number for your site.

‍Are toilets required by law?
Construction sites must provide suitable and sufficient sanitary conveniences as part of their welfare provision.

‍Do I need handwashing facilities too?
Yes. Suitable handwashing facilities must be provided in the immediate vicinity of your toilets. By suitable, this means hot (warm) and cold running water with soap and drying facilities) such as paper towels or a hand dryer.

‍How often should toilets be serviced?
It depends on usage. Weekly servicing is a minimum expectation, but busy sites may need more frequent servicing, and these can be added onto your hire if needed.

‍Where should toilets be positioned?
‍
Somewhere readily accessible to workers, on suitable ground, where it is not soft or uneven, and where servicing vehicles can safely reach them.

‍Do portable toilets meet HSE guidelines for construction sites?
Yes, where appropriate. HSE guidance states that portable chemical toilets are acceptable on construction sites where other adequate provision is not reasonably practicable. They must be kept clean, be readily accessible to workers, and be accompanied by suitable handwashing facilities including warm water, soap and drying facilities.

PLEASE NOTE: Toilet numbers, servicing and positioning should be planned around the actual construction site rather than treated as a one-size-fits-all calculation.

Constructionsite welfare requirements

Construction projects in Great Britain are subject to the Construction (Design and Management) Regulations 2015 (CDM). The practical guide of how to fulfill these legal obligations are covered in HSEguidance, in other words, if you’re meeting the guidance recommendations, you are meeting the legal responsibilities.

The HSE states that welfare provision, including its location and regular maintenance, should be considered during the planning and preparation stages ofa project, before construction work begins.

Who is responsible for construction-site welfare?

The principal contractor has a key responsibility for ensuring suitable welfare facilities are provided throughout the construction phase. Contractors, including self-employed workers, also have responsibilities to ensure adequate welfare facilities are available for workers under their control.

Welfare therefore needs to form part of the construction planning process rather than being treated as an afterthought. The HSE’s guidance specifically recommends considering:

  • The number of people who will use the facilities
  • How far workers have to travel (to facilities)
  • The duration of the work
  • Whether workers will be working in different locations
  • Cleaning and maintenance
  • Whether facilities will need to be relocated as the project develops

How Many Toilets Does a Construction Site Need?

The commonly used starting point is one portable toilet for every seven workers on a standard 40-hour week where toilets are emptied weekly. This figure comes from BS6465 guidance referenced by the HSE.
Workers on site Toilets required
1 to 71
8 to 142
15 to 213
22 to 284
29 to 355
36 to 426
43 to 497
508
7010
10015
PLEASE NOTE: These figures are a starting point. Site requirements vary depending on workforce numbers, working patterns, site size and servicing frequency.

Where Should Construction Toilets
Be Positioned?

Getting the location right from the start prevents problems later. Three things to consider before delivery.

‍Keep toilets accessible to workers
Workers should be able to reach facilities without an unnecessary journey. On larger sites, satellite toilets may be needed. HSE guidance recommends that distance to facilities is considered during planning.

‍Think about the servicing vehicle first
A toilet may be perfectly placed for workers but inaccessible to the vehicle that needs to service it. Consider vehicle access, site entrances, turning space, ground conditions and changes to the site layout when agreeing positioning.

‍Avoid soft or unstable ground
Grass may look convenient at the start of a project but wet weather and vehicle movements can quickly make it unsuitable. A firm, level surface is always preferable.

How Much Does Construction Site Toilet Hire Cost?

There is no single price because every project is different. The main factors are the number of units, the type of toilet, hire duration, servicing frequency and site location. The cheapest option is not always the right one if toilets are too few, too far away or serviced too infrequently.

To get an accurate quote, tell us your site location, approximate number of workers, expected hire period and any specific site access requirements.
