Filtering in Independent Schools in the UK: What Proprietors Need to Have in Place
Independent schools follow the same filtering and monitoring expectations as state schools, but they meet them with smaller teams, their own inspectorate in many cases, and often a boarding house full of personal phones.
This guide is for heads, bursars, DSLs, IT managers and governors of independent schools in England. It explains where the duty comes from and what good evidence looks like.
Talk to us about your schoolFrom regulation to router: the chain behind independent school filtering
The filtering expectation for an independent school is not a separate rulebook. It flows from the regulations that every independent school in England must meet, through KCSIE, into the DfE standards.
Independent School Standards
The regulations require the proprietor to make arrangements to safeguard and promote pupils' welfare, having regard to the Secretary of State's guidance.
Keeping Children Safe in Education
That guidance includes KCSIE, which expects appropriate filtering and monitoring and a review at least once every academic year.
DfE filtering and monitoring standards
KCSIE points to the DfE standards, which set out roles, the yearly review, blocking without harming learning, and monitoring.
Your settings and records
The proprietor needs evidence that the system in place matches the policy, the pupils and the risks of this school.
For the detail of each step, see our guides to KCSIE filtering and monitoring and the DfE filtering and monitoring standards.
A filter whose settings and reports you can show a proprietor
Our hosted CIPA filter is run for you, which suits a school without a large IT department. You hold the category choices, the lists and the reports, and we handle the service behind them.
- Day houses and boarding houses can keep separate category settings
- A policy record and activity reports can go into the inspection folder
- The log export is there when a governor or inspector asks for more
ISI or Ofsted: who checks your filtering
Which inspectorate visits depends on whether the school belongs to one of the associations that make up the Independent Schools Council. Both look at whether the Independent School Standards, including safeguarding, are met.
Independent Schools Inspectorate
Inspects schools in membership of the Independent Schools Council associations. Its framework in use since September 2023 looks at provision through the lens of pupils' wellbeing.
- Reports include a separate safeguarding section
- Reports do not use one-word grades
- Inspectors check that statutory safeguarding requirements are met on every inspection
- Check ISI's current framework for the exact wording
Ofsted
Inspects independent schools that are not in an association, using an independent schools inspection toolkit alongside its state-funded schools toolkit.
- Judges whether the Independent School Standards are met
- Looks at how leaders protect pupils from harm, including online harm
- Talks to pupils about how safe they feel
- See our guide to Ofsted online safety inspection
Neither inspectorate wants a filtering file made for the visit. What helps is the evidence a school already keeps: the policy, the annual review record, the check log and examples of how concerns were handled.
Naming filtering and monitoring roles in a smaller school
The DfE standards ask for named people: a senior leader and a governor responsible for the standards, a DSL, and IT support. In a 200-pupil prep school, one person may wear two hats. That is fine if the roles are written down.
| Role in the standards | Typical holder in an independent school | What they should be able to show |
|---|---|---|
| Proprietor | Board of governors or trustees of the school's charity or company | Minutes showing filtering and monitoring was reviewed and approved |
| Responsible governor | The safeguarding governor, often a parent or former teacher | Notes from a visit or meeting with the DSL about the review |
| Senior leader | Head, deputy head or, in some schools, the bursar with a safeguarding brief | The annual review record and the reasons for what is blocked |
| DSL | Deputy head pastoral or a dedicated safeguarding lead | How monitoring reports reach them and what they did with them |
| IT support | An IT manager, a part-time technician or an outside managed service | The settings, the record of changes and the technical check results |
| Boarding lead | Head of boarding or house parents | How boarding house networks and devices are covered in the evening |
Where IT is outsourced, the contract should say what the provider does when a concern appears in a log. Our guide to choosing a school web filter lists questions for that conversation.
Boarding schools: what the national minimum standards add
The national minimum standards for boarding schools in force from 5 September 2022 bring online safety into the boarding house itself. These points paraphrase what they cover; read the current standards for the exact wording.
Internet access for boarders
Boarders should have suitable internet access for study and social use, and the standards point to KCSIE for the filtering and monitoring that goes with it.
Online safety in safeguarding
Boarders should be safeguarded from harmful and inappropriate online material, with the school's approach set out in its child protection policy.
Boarders' own devices
Policies should cover devices brought into school, harmful content already on them, and mobile data that can bypass school filtering and monitoring.
Contact with families
Boarders should be able to contact parents privately, at suitable times across time zones, while the school runs proportionate controls on electronic communications.
Surveillance and biometrics
Any surveillance equipment or biometric technology in boarding should have a written rationale. That is worth remembering when choosing monitoring tools too.
Additional boarding factors
KCSIE recognises that boarding schools have extra safeguarding factors to consider, which the boarding standards reflect in the child protection policy.
A day in the boarding house: where filtering matters most
Day-school filtering is built around lessons. Boarding filtering has to work at nine in the evening, at weekends and through the night. Here is how the risk shifts across a boarder's day.
Lessons
School devices on school wifi, with year group profiles and teacher supervision.
Activities and prep
Study rooms and library. Research needs room, so over-blocking hurts most here.
House time
Personal phones and laptops on house wifi. Streaming, gaming and social apps compete with homework.
Night
Many houses apply a night-time profile or switch off pupil wifi. Mobile data remains a gap.
For pupils' own devices, see BYOD filtering in schools. For workarounds, see stopping proxy and VPN bypass in schools.
Messaging and VPN names that boarders arrive with
International boarders often bring services they use with family overseas. These labels come from our database.
| Domain | Categories in our data | House staff point |
|---|---|---|
| whatsapp.com | Email and Messaging, Social Networking | How many boarders keep in touch with family |
| snapchat.com | Social Networking | Popular with older boarders after prep |
| discord.com | Email and Messaging, Social Networking, Gaming | Chat that falls under three switches |
| nordvpn.com | File Sharing/P2P, VPN / Proxy / Anonymizers | A VPN used to reach home-country services |
| bbc.co.uk | News/Media | News that is simply left open |
International boarders and filtering: practical points
Many independent schools welcome pupils from overseas. Their online lives often run in other languages and on apps that are less familiar to UK staff. Filtering policy should reflect that without treating any group as suspect.
What tends to come up
- Pupils arrive with VPN apps already installed for use in their home country
- Messaging and video apps used to call family across time zones
- News and entertainment sites in languages staff do not read
- Educational agents and guardians who need to reach pupils online
How schools usually respond
- Explain the device and VPN rules in the pupil's first language at induction
- Allow family contact in line with boarding Standard 12
- Rely on categories rather than staff reading every site, since category data does not depend on the page language
- Ask providers about multiple language support, a feature in the UK Safer Internet Centre definitions
Over-blocking and the independent school curriculum
KCSIE warns that over-blocking can lead to unreasonable restrictions on what children are taught. Independent schools with strong sixth forms, art and music departments or research projects feel this sharply.
| Subject or activity | What often gets blocked by mistake | A better approach |
|---|---|---|
| Art history and life drawing | Museum and gallery pages with classical nudes | Keep Adult blocked, but allow Arts & Entertainment and review false matches |
| Biology and PSHE | Sexual health and puberty resources | Allow Health & Medicine for secondary year groups |
| History and politics | Primary sources on extremism and war | Allow Political and News/Media, block Hate/Discrimination |
| EPQ and university research | Forums and blogs used as sources | Sixth form profile with Forums / Message Boards allowed |
| Computing | Code hosting and developer tools | Allow Developer Tools / Code Hosting for computing groups |
| Careers and UCAS | Job boards and company sites | Allow Job Search/Careers from Year 10 upwards |
A clear category taxonomy makes these choices easier to explain to parents and inspectors. See the web filtering categories taxonomy, and our broader page on web filtering for independent and private schools.
Keeping house rules on devices the school did not buy
Devices on the school network follow the one DNS setting without anything being installed on them. A private encrypted link carries the same rules to phones and laptops away from the network, and public encrypted DNS and browser settings that skip the filter are blocked by default.
Explaining filtering to fee-paying parents
KCSIE expects schools to tell parents what filtering and monitoring is in place. In independent schools, parents often ask sharper questions, and a clear answer builds trust long before any incident.
What is filtered, and where
Explain that school devices and school networks are filtered, by year group, and that house wifi has its own evening rules.
What is not covered
Be honest that mobile data and home broadband sit outside school filtering, and suggest settings parents can use at home.
Who to contact
Name the DSL and explain how a parent raises a concern about something their child saw online.
Promises of total safety
No filter is fully effective. Parents trust a school more when it explains the layers: filtering, supervision, teaching and pastoral care.
Jargon
Talk about "gambling sites" and "adult content", not DNS or proxies. Category names help here because they read like plain English.
Questions at induction
New boarding families in particular welcome a short session on devices, phone hand-in and how contact home works.
A termly filtering rhythm for independent schools
The three-term year, with long holidays and boarding exeats, gives natural points to check filtering. Spreading the work avoids one rushed review each summer.
| Term | Filtering tasks | Who leads |
|---|---|---|
| Michaelmas (autumn) | Induct new pupils and boarders on device rules; run checks on new devices; train new staff on how to report a concern | DSL and IT |
| Lent (spring) | Review blocked request patterns; check night-time profiles in boarding houses; update the record of local exceptions | IT and head of boarding |
| Summer | Hold the annual review; report findings to the proprietor; plan changes for September, including any provider change | Senior leader with governors |
| Holidays | Apply software updates and configuration changes, then re-test before pupils return | IT |
The filtering evidence an independent school should be able to find quickly
Bursars and heads often ask what "good" looks like on paper. This list matches the documents most schools already produce, rather than adding new ones.
The filtering and monitoring annual review checklist gives a ready structure. If you are choosing a provider, read our appropriate filtering provider checklist first.
Category data and a hosted filter for independent schools
We supply website category data and a hosted DNS filter built on it. Website category filtering is one layer. Monitoring, pastoral care and responses to concerns stay with your DSL and your safeguarding process.
120 million domains
The 20 million most visited domains, which cover 99.99% of web traffic and usage, are all categorised.
New sites every day
About 300,000 newly registered domains are categorised daily and checked again after a week and a month.
58 plain categories
Names a governor can read, with several categories per domain ranked by how much of the site they describe.
We do not supply the IWF list or the police-assessed terrorism list; those come through accredited filtering providers. For a small school, the hosted DNS filter is the simplest route. Schools and providers with their own systems can license the category database, or test any site in the domain category checker.
Self-managed filtering or a hosted service for an independent school
The rows look at the tasks that fall to a bursar, a head of IT and a boarding house team.
| Task | Run by the school | Hosted CIPA filter |
|---|---|---|
| Set-up on a spread-out site | Equipment in several buildings | One DNS setting on the router or firewall |
| Day pupils and boarders | Two policies to build and keep aligned | One console, separate settings per school or branch |
| Housemaster's request | Rule edit, then a reminder to reverse it | Always-allow and always-block lists, applied in seconds |
| Boarders using a VPN | A growing list of VPN names | VPN/Proxy/Anonymizers blocked as a category, even with a PIN |
| Proof for inspectors | Screenshots and notes | Activity reports, a policy record and a log export |
| Staff reading adult material for work | Disable the block for a while | PIN bypass for 15, 30 or 60 minutes, logged, then it reverts |
Independent school filtering: frequently asked questions
Does KCSIE apply to independent schools?
Yes. KCSIE is statutory guidance for schools in England, including independent schools. The Independent School Standards require proprietors to make safeguarding arrangements that have regard to the Secretary of State's guidance, which includes KCSIE.
Who inspects filtering in an independent school?
Schools in the Independent Schools Council associations are inspected by ISI. Other independent schools in England are inspected by Ofsted. Both check whether the Independent School Standards, including safeguarding, are met.
What do the boarding national minimum standards say about online safety?
They expect boarders to be safeguarded from harmful and inappropriate online material, with the approach set out in the child protection policy. They also ask schools to consider boarders' own devices and mobile data that bypasses school filtering.
Who is the proprietor in an independent school?
The person or body responsible for running the school, often a board of governors or trustees of a charity or company. The proprietor carries the duty to have appropriate filtering and monitoring and to review it each year.
Can a small prep school meet the filtering standards without an IT team?
Yes, but the roles still need names. Many small schools buy a managed or hosted filter and agree in writing what the provider does, what the DSL does and who leads the annual review.
Does this apply to independent schools in Wales, Scotland and Northern Ireland?
No, not directly. KCSIE, the DfE standards and the boarding standards described here apply in England. The other nations publish their own safeguarding guidance, so independent schools there should check their own government's current guidance, though the UK Safer Internet Centre definitions are written for use across the UK.
Should sixth formers have different filtering from younger pupils?
Usually, yes. The standards expect filtering that fits the age and ability of users. Many schools give the sixth form a separate profile with wider access for research, careers and university applications, while keeping illegal, adult, gambling and bypass categories blocked for every age group.
Do you monitor boarders' phones or messages?
No. We supply website category data and a hosted DNS filter. We do not monitor messages, chats or behaviour. Concerns about a pupil go through the school's safeguarding process and DSL. Our UK filtering and monitoring hub links to the wider guidance.
Pricing follows how many houses, buildings and devices you have, and our quote arrives within one business day. A pilot in a single house or building would show the blocks and the reports before the full school is switched.
