How Long Do Organisations Have to Respond to FOI Requests? UK 20 Day Rule Explained (2026)
Share
If you are asking how long organisations in the UK have to respond to Freedom of Information requests, the answer is straightforward:
Most public authorities must respond within 20 working days.
This rule comes from Section 10 of the Freedom of Information Act 2000 (FOIA) and applies to councils, government departments, NHS bodies, schools, police forces, universities, and other public authorities.
In this detailed 2026 guide, we explain the UK’s 20 day FOI rule, when extensions are allowed, what happens if an authority delays, and what rights requesters have.
Quick Answer: What Is the UK 20 Day FOI Rule?
Under the Freedom of Information Act 2000, organisations normally have:
20 working days to respond to an FOI request
This means:
- weekends do not count
- bank holidays do not count
- the countdown starts on the first working day after receipt
Featured Snippet Answer
Public authorities in the UK must usually respond to Freedom of Information requests within 20 working days under the Freedom of Information Act 2000. The clock starts on the first working day after the request is received.
What Counts as a “Working Day”?
A working day means:
- Monday
- Tuesday
- Wednesday
- Thursday
- Friday
excluding:
- Saturdays
- Sundays
- public holidays
- bank holidays
For example:
If you submit an FOI request on Friday, day 1 is Monday.
If you submit it on a Sunday, day 1 is still Monday.
FOI Response Time Table
| Request Sent | Day 1 Starts | Latest Standard Response Date |
|---|---|---|
| Monday | Tuesday | 4 weeks later (approx.) |
| Friday | Monday | 4 weeks later (approx.) |
| Sunday | Monday | 4 weeks later (approx.) |
Because it is based on working days, the actual calendar time is usually around 28 to 30 days.
The Law Behind the 20 Day Rule
The legal basis is Section 10 of the Freedom of Information Act 2000.
The ICO explains that organisations must respond:
promptly and no later than the twentieth working day following receipt
This applies whether the response is:
- disclosure of the information
- confirmation information is not held
- refusal notice
- request for clarification
The 20 day period is considered the maximum standard limit, not the target.
Authorities are still expected to reply as soon as reasonably practicable.
Important: It Is 20 Working Days, Not 20 Calendar Days
This is one of the most common misunderstandings.
Many people wrongly assume 20 days means less than three weeks.
It actually means 20 business days, which is closer to four weeks.
Example
Request submitted: 1 April 2026 (Wednesday)
Day 1: 2 April 2026 (Thursday)
Expected deadline: around 29 April 2026
This excludes weekends and public holidays.
Can Organisations Take Longer Than 20 Days?
Yes, but only in specific circumstances.
1. Public Interest Test Extension
Where the authority needs more time to consider whether an exemption applies and the public interest test must be assessed, they may extend the deadline.
The ICO states this is usually:
up to an additional 20 working days
This means the total may become 40 working days.
Example Situations
- national security concerns
- law enforcement exemptions
- commercial confidentiality
- policy discussions
- third party consultations
2. Clarification Needed
If your request is unclear, the authority can pause the clock and ask for clarification.
The response period does not begin until clarification is received.
Example:
Instead of asking:
“Send all records”
Ask:
“Please provide all email correspondence relating to the data breach investigation between January and March 2026.”
This makes it easier to process.
Real World Example
A council receives an FOI request asking for:
“all complaints made about CCTV surveillance policy in 2025”
Because the request is clear and specific, the council must respond within 20 working days.
If it intends to withhold part of the information using an exemption, it still must issue a response or notice within that timeframe.
What Happens If They Miss the Deadline?
If the organisation fails to respond within 20 working days, it may be in breach of FOIA.
The first step is usually to request an internal review.
Internal Review Time
The ICO recommends internal reviews should usually be completed within:
20 working days
and in complex cases no more than:
40 working days
When to Escalate to the ICO
If the authority still does not respond, you can complain to the Information Commissioner’s Office (ICO).
The ICO regulates FOI compliance in the UK and can investigate delayed or unlawful refusals.
This is especially useful where:
- the deadline has passed
- no refusal notice was given
- the authority is ignoring follow ups
- excessive delays continue
Special Rule for Schools
Schools sometimes operate under a slightly different timeframe.
The ICO notes that for schools the response time may be:
20 school days or 60 working days if shorter
This is an important exception in 2026 searches.
FOI vs SAR Response Time
People often confuse FOI requests with Subject Access Requests (SARs).
| Type | Time Limit |
|---|---|
| FOI request | 20 working days |
| SAR under UK GDPR | 1 calendar month |
FOI concerns public information.
SAR concerns your personal data.
This distinction is critical for privacy and data protection compliance content.

Final Expert Verdict
In 2026, the UK FOI response rule remains clear:

For requesters, understanding this rule helps you know when a delay is lawful and when it may amount to non compliance.
