What is classed as environmental information?
Environmental information comprises:
- The state of elements of the environment, such as air, water, soil, land, fauna (including human beings).
- Emissions and discharges, including noise, energy, radiation, waste and other such substances.
- Measures and activities such as policies, plans, and agreements affecting or likely to affect the state of the elements of the environment.
- Reports, cost-benefit and economic analyses.
- The state of human health and safety, and contamination of the food chain.
- Cultural sites and built structures (to the extent they may be affected by the state of the elements of the environment).
Our maps and data are not classified as environmental information under EIR.
Our map data merely shows that a topographical feature exists in a particular geographic position and does not declare either the state of a feature or whether any activity has an effect upon it.
Requests for access to our mapping data under EIR will, in the majority of cases, be treated under the section 6 (1) (b) exception under EIR.
Access to information under the EIR is subject to exceptions. If an exception applies, access to the information may be refused. Some exceptions in the regulations are subject to a public interest test. This means that we must explain why the public interest in withholding information outweighs that of disclosure. There is a general presumption in favour of disclosure.

The Information Commissioner’s Office has a useful guide: How to access information from a public body, which provides useful information to consider when making a request.
We do not normally charge for this service.
Although we do not normally charge for providing information in accordance with the Environmental Information Regulations, the regulations do allow us to apply a fee for ‘making environmental information available’.
If you are unhappy with our response to a request you have made under the Environmental Information Regulations (EIR), you have the right to request an internal review of the decision.
You may send your complaint via the following methods:
- Complete the online form below
- Write to us at Ordnance Survey, Explorer House, Adanac Drive, Southampton, SO16 0AS
An independent Ordnance Survey official (the Internal Review Officer), who has not been involved with your request, will be asked to undertake an internal review of the process to determine whether this has been followed in line with the FOIA or EIR.
You may request an internal review within two months of receipt of our final response to your FOI request or within 40 working days of receipt of our final response to your EIR request.
The Internal Review Officer will inform you of the outcome of the internal review, normally within 20 working days, but exceptionally within 40 working days, in line with the Information Commissioner’s guidance. The Internal Review Officer will either uphold the original decision, provide an additional explanation of the exemption/exception applied, or release further information if it is considered appropriate to do so.
Please quote your original reference on all correspondence.
Appeal to the Information Commissioner's Office (ICO)
If you remain dissatisfied, following the outcome of the internal review, you may raise an appeal with the Information Commissioner’s Office (ICO), within three months of receiving our response to the request you made under the Environmental Information Regulations (EIR).
- Visit the ICO website (ico.org.uk) to report a concern.
- Call the ICO helpline on 0303 123 1113.
What happens next?
We will advise you within 20 working days if we hold the information you have requested and can release it.
The Environmental Information Regulations Act allows us, in exceptional cases, to extend the 20 working day response time where we are exempting information in accordance with a qualified exemption. This allows us to fully consider where the public interest lies.
If your requested information falls within categories specified in the Act, such as personal data about individual employees, we may withhold it.
