What Information Can Local Councils Legally Keep Secret?

When you request information from a local council, they sometimes refuse or release only partial information. This isn't always obstruction—the Freedom of Information Act includes specific exemptions where councils can lawfully keep secrets. Understanding these exemptions helps you recognise legitimate refusals and spot when councils are being unnecessarily secretive.

Personal data exemption Councils cannot release information that identifies individuals, including names, addresses, or other personal details. This protects privacy for residents, employees, and contractors. However, councils can often provide anonymised data or aggregate figures that don't identify anyone.

Commercial confidentiality Information about supplier contracts, pricing, or business strategies can be withheld if disclosure would harm a company's competitive position. This encourages businesses to work with councils openly. However, councils must still release basic spending information and can't hide contracts just because they're commercially sensitive.

Legal privilege Communications between councils and their lawyers are confidential. Councils can't be forced to reveal legal advice or documents prepared for litigation. This ensures they can get honest advice without information being used against them.

National security and public safety Information that could endanger national security, defence, or law enforcement is exempt. In practice, this rarely applies to local councils, but it might cover police intelligence or counter-terrorism information.

Prejudice to ongoing investigations or proceedings Councils can withhold information about active investigations, complaints, or court cases. Once matters are concluded, they often become public. This exemption prevents information from interfering with justice.

Environmental information exceptions Despite having separate environmental information rules, councils can refuse to disclose details about wildlife locations or conservation strategies if disclosure would harm species protection.

Information intended for future publication Councils can delay releasing information they plan to publish soon, though they can't withhold it indefinitely using this excuse.

Important distinction: qualified versus absolute exemptions Some exemptions are "absolute," meaning councils must refuse requests. Others are "qualified," requiring councils to balance public interest in disclosure against the harm caused by releasing information. For qualified exemptions, councils must prove that keeping the secret serves a legitimate purpose more important than transparency.

Recognising abuse of exemptions Councils occasionally use exemptions inappropriately. If a refusal seems unjustified, you can appeal to the Information Commissioner's Office. The ICO investigates whether councils properly applied exemptions and can order release of improperly withheld information.

Understanding these exemptions makes you a smarter information requester. You'll know which refusals are legitimate and which deserve challenge, helping ensure councils remain genuinely accountable to their communities.
