Local Authority Use

Local Authority Registration

Local Authorities in London are able to set up user accounts in order to view the NRMM register. You must be an appropriate employee of a London local authority to get a local authority account e.g. a pollution control officer or similar role.

If your local authority does not already have an account you can request one by email. Once your identity has been confirmed you will then be sent an email to your supplied email account, which will have a link that will allow you to set your password. The email comes from - you may need to add this email address to your contacts as some anti-spam systems may block it.

Logging In

You can then log in at /user-nrmm, using the user name and the password you have selected. If you forget these details you can request a new password.

Viewing NRMM Sites

Once logged in you can view all NRMM sites using the page /nrmm/nrmm-site-list. On this page you can:

  • Filter for developments within a chosen London borough by selecting it from the "Borough" drop down control near the top of the list and pressing "Apply".
  • Sort the list by pressing on any column names that are hyperlinks e.g. "Created Date" would allow you to see the most recent additions.
  • View all the fields for the NRMM site by pressing "View" under the Site Column. This will list all the fields for the NRMM site, you can return to the NRMM Site List by pressing "back" on your browser.
  • View all the NRMM register entries for the site by pressing "View" under the Register column. This will return a full list of all NRMM register entries for that site, if no data appears then the site has not yet entered any data. Again, columns that are hyperlinks can be pressed to Sort the list. Entry status shows if the entry has passed basic checks - if it is not "Ok" then there may be something wrong with the entry. You can also press "view" at the end of the row to see the full detail of each entry.

What will local authorities do?

Local authorities will implement the NRMM LEZ through planning conditions attached to planning permissions or section 106 agreements. You can find the full local authority guidance here

How will local authorities make sure the policy is being implemented within applications for developments on eligible development sites?

Local authorities will ensure the requirements are set out in the developers air quality management plan, if not - they should advise the applicant of the standards and secure compliance through additional planning conditions or s106 agreement.

Is there an introductory period for the new NRMM LEZ requirements?

The Greater London Authority recognise that it will take time to ensure all local authorities are properly trained and understand the policy and to ensure that the industry is aware of its obligations. As a result we envisage a 'soft launch' for the first six months, where the emphasis will be on informing and training rather than any enforcement of penalties.

How will the policy be enforced?

The Greater London Authority has developed a new NRMM Register as a desktop tool to make enforcement as simple as possible. Once a local Authority has sign-up  it is possible to view the NRMM register entries for a specific development site and check that they are compliant with the NRMM LEZ policy.

What should local authorities do if a development site has not registered?

The local authority planning enforcement officer should contact the site manager to request that the site is registered at If the site then fails to register the required information they will be in breach of the planning requirements.

What will happen if a development site is using equipment that is non-compliant for the NRMM LEZ?

On first inspection of the NRMM register the local authority will inform the site manager that there are a number of options available in order to comply with the requirements of the NRMM policy:

  • Reorganisation of NRMM fleet so that only compliant equipment is used in London
  • Replacing equipment (with new or second hand equipment which meets the policy)
  • Retrofit abatement technologies
  • Re-engining
  • If eligible, apply for an exemption

If on subsequent inspections the development site is still using NRMM that does not comply with the NRMM LEZ policy then it may be neccessary to take further enforcement action.

What are the penalties for failing to comply with the NRMM LEZ requirements?

Penalties will depend on the individual borough and their planning enforcement teams. Options available include delaying sign-off of the s106 agreement or building control approval a delay the final completion of the project which could have an implied financial cost for the company concerned.
