Freedom of information and environmental information requests
If your request is about information relating to the environment, the request falls to be dealt with under the Environmental Information Regulations 2004 (EIR) rather than under the Freedom of Information Act 2000.
The Information Commissioner's Office has issued guidance on “what is environmental information?”

Regulation 8 of EIR contains a charging regime and the Information Commissioner's Office has issued guidance (Charging for Environmental Information Regulation 8)

Under Regulation 8, public authorities have to publish their schedule of charges under EIR and the council's charges.
