Welfare Unit Servicing From Challenger Site Services

We are perhaps best known for our supply of portable toilets for hire. However, we also service welfare units and chemical toilets for others. We can service both large waste and water welfare units and welfares containing chemical toilets.

Chemical Welfare Units

Chemical welfare units house a self-contained, re-circulating chemical toilet. We can service your chemical welfare units on a regular weekly basis as part of our service rounds for our own chemical portable toilets.

  • Regular Weekly Service Visit
  • Fresh chemical, water and paper products
  • Digital proof of service and waste transfernotes
  • Before & After Service Photos

Waste & Water Welfare Units

Larger welfare units that contain separate waste and water tanks supplying the toilet facilities can be serviced by our larger tanker fleet on a schedule that suits you.

  • Reliable, regular service to suit your schedule
  • Whatever schedule you require – daily, twice a week, three times a week, fortnightly, monthly or on call off
  • Next day and same day (subject to availability)
  • Fully licenced waste carriers
  • Leading experts in the industry
  • Digital proof of service and waste transfernotes
  • Before & After Service Photos

Chemical Toilets

We can carry out a regular weekly service on your own portable toilet to assist compliance with British Standard BS6465-1:2006, which recommends that 1 toilet being used by up to 7 people is serviced once a week.

  • Waste removal
  • Water and chemical replenishment
  • Paper products replaced
  • Hand soap (if dispenser is compatible)
  • Surfaces washed, wiped down and refreshed.
  • Digital proof of service and waste transfernotes
  • Before & After Service Photos


  • A chemical welfare unit will hold a self-contained, chemical, re-circulating toilet, similar to that found in a portable toilet. A waste and water welfare unit will have a toilet and sink similar to that which you may find in a plumbed in toilet, however this facility will be fed by a large water tank and fed into a large waste tank.

  • We service both kinds of welfare unit, just make sure you let us know which type it is as they’re serviced by completely different vehicles.

  • Chemical welfare units are serviced alongside our portable toilets by our fleet of service vehicles on a weekly basis, waste and water welfare units are serviced by our tanker fleet on an ad-hoc or recurring basis.

  • As well as customer’s welfare units, we also service portable toilets owned by customers who don’t have the facility to service them.

  • Chemical welfare units will be fed in to our weekly service rounds and serviced no later than 7 days from point of order. We operate a next day service for waste and water welfare unit orders placed before 3pm.

  • We service the entirety of North-West England including, Tameside, Manchester, Liverpool, Warrington, Cheshire, Chester, Wigan, Bolton, Bury, Preston, Blackburn, Burnley, Stockport, Salford, Rochdale, Macclesfield, Stoke, Crewe, Northwich, Nantwich.

  • Of course, just give us a call first so we know to expect you, bring in your chemical welfare unit or welfare van and we can service it for you as you wait.
