The information on these pages is primarily intended for NNL employees. None of the information is protectively marked. The details are largely a replica of what you will find on Nucleus, placed here as a contingency in the event that there are access problems on our network. The website is hosted separately to NNL’s main network.


As we continue to adapt to the challenges COVID-19 brings, we recognise that colleagues may want to access both current and previously released information in a central place.

Your comms team has created this information area to bring together NNL and official information to make it easier for you to keep updated.

These pages will be updated regularly. If you think there’s anything else we should include, please email
