Weighbridge Operator Licence

What does the law require?

Every person who carries out weighing on a public weighbridge for which a charge is made must hold a Certificate from a Chief Inspector of Weights and Measures to show that he/she is sufficiently knowledgeable to carry out that weighing.

If you wish to obtain a Weighbridge Operator Licence Certificate please complete the online form below.

Apply for a Weighbridge Operator Licence Certificate 

Trading Standards will then be in contact to make arrangements for you to sit an informal test. Successful applicants will be issued with a Public Weighbridge Operators Certificate. This is not transferable to another person and will only be valid for the weighbridge type(s) for which the person was tested.

A short test is given which covers the legal requirements of the duties. This includes the ability to subtract tare weights from gross weights correctly. The questions are designed to demonstrate that you have a practical working knowledge of the use of the equipment.

Questions relating to the operation of the weighbridge to be used will include: 

  1. the need to have basic computer literacy and knowledge of computer based weighing instruments;
  2. the need to keep the machine properly balanced and the method of achieving this;
  3. the meaning of the terms 'gross weight', 'tare weight' and 'net weight' and the ability to record a weighing correctly;
  4. the operation of the weighbridge with emphasis on ticket printing and recording mechanisms;
  5. common faults likely to lead to weighing inaccuracy, for example badly or incorrectly located loads, fouling of the plate and surround, flooding of the pit, dirt on plate, electrical fault, etc;
  6. precautions to be observed when weighing, for example visibility of plate, proper positioning of vehicles, engines to be switched off; drivers and passengers not to be in vehicle or on platform during weighing;
  7. dangers of multiple weighing (illegal since September 1991);
  8. the responsibilities imposed on keepers of public weighing equipment by the Weights and Measures Act and the liabilities connected with:
  • Failure to carry out weighing on demand
  • Unfair weighing
  • Failure to give a statement in writing of the weight
  • Failure to make a record of the weighing
  • Falsification of weight statement and/or records
  • Carrying out of fraud in any weighing
  • Failure to retain and/or produce records to an Inspector
  • Wilful destruction or defacement of records

correct completion of documents:

  • always insert date and time
  • gross and tare weights should never be in the same document unless weighing made within 24 hours of each other
  • do not leave blank spaces, cross through or write in "not ascertained"
  • all entries and cancellations made indelibly; do not use pencil
  • avoid alterations

Period of time records have to be kept, currently for at least two years.

A public weighbridge operator must comply with legal requirements. Failure to do so may result in court proceedings. The current penalty is a fine of up to £5,000 or 6 months imprisonment or both.

Some offences have a maximum penalty of a fine up to £2,000 only.
