Freedom of Information Requests
NNL Chadwick House

Please note that requests sent via post may be subject to a delay as most people are currently working out of the office. If possible, please email any requests instead.

We will aim to find the information you require as soon as possible. However, we will send you a response within 20 working days of your initial request.

If we do not hold the information that you require, we will inform you. In certain circumstances we may need to transfer your request to another organisation which holds the information. If this is necessary we will inform you.

If the information you have requested relates to a third party, NNL will consult with the third party regarding the disclosure of the information.

In some circumstances a fee may be payable and if that is the case, we will let you know the likely charges before proceeding.
