REACH - Registration, Evaluation, Authorisation and restriction of Chemicals


The legislation that gives effect to Registration, Evaluation, Authorisation and restriction of Chemicals (REACH), is the REACH Enforcement Regulations 2008, SI 2852.

Local authorities now have a very limited role enforcing REACH where a Part A2 or B installation:

  • manufactures a relevant chemical for its own-use, or to supply to others, or
  • uses a relevant chemical at levels above specified thresholds.

The role has been given to authorities as a better regulation measure: to minimise the extent to which the Environment Agency also has a function at A2 and B-regulated installations.

In particular, there is no expectation that authorities will either 

  1. identify A2 and B installations which manufacturer REACH chemicals, or users of >1 tonne of such chemicals, or 
  2. check the data sheets of A2 and B installations for REACH-related information.

Notwithstanding the above, it is recognised that local authorities can have a valuable part to play in support of the Environment Agency, including obtaining information on high-risk sites and discussing action.

Operators of A2 or B installations ought to check with their chemicals suppliers to find out whether the chemicals they use are covered by REACH. The supplier ought to be able to supply either a pre-registration or registration number where this is the case. Once a chemical is registered, the registration number should appear on the safety data sheets.

If a Part A2 or B installation uses a chemical covered by REACH it is described as a “downstream user”. The main requirement on these users is to prepare a chemical safety report; but this is only needed if the installation uses 1 tonne or more of the chemical a year. 

It is very unlikely that any A2 or B installation will manufacture any chemicals covered by REACH. 

Several short guidance leaflets, tailored to different aspects of REACH, can be found on the Health and Safety Executive (HSE) website.
