SLfT2008 - Requirement to use a weighbridge to weigh waste

SLfT guidance on the requirement to use a weighbridge to weigh waste for SLfT purposes.

Sites with a working weighbridge

The basic method of calculating the weight of waste is by weighing it at the landfill site immediately prior to the time of disposal. If there is a working weighbridge at your landfill site, you must use it to weigh waste immediately prior to disposal.

Any weighbridges should be calibrated (in accordance with weights and measures legislation – see The Weights and Measures Act 1985) and maintained regularly to minimise breakdowns.


If you do not have a working weighbridge on your site, then one which is within close enough proximity (so as not to incur unreasonable extra cost) must be used instead (see below).

In exceptional circumstances you can ask us to agree an alternative method of calculating the weight - see SLfT2009.

Sites nearby with a working weighbridge

Where a working weighbridge on a nearby site is used, you must:

  • notify us where your waste is being weighed by writing to us at the contact address on our website; and
  • keep a clear audit trail of this activity, including:
    • a record of weights for each vehicle or container. Where vehicles go directly to the landfill site after being weighed, and the waste is not interfered with between weighing and disposal, this weight can be used to calculate your SLfT liability; and
    • a record of all waste brought onto your site(s), showing where the waste was weighed, the identifying number and type of vehicle/container, a description of the waste, and the date and time disposed at your site. You must also record and retain the weighbridge tickets.
