What a guardian is, and is not
A guardian is the responsible adult based in the same country as the school who acts as the parents' representative for the child while the parents are abroad. The guardian is not the legal guardian in the family law sense; parental responsibility remains with the parents. The guardian is also not the school's safeguarding officer; that role remains with the school's designated safeguarding lead.
What the guardian is, in practical terms, is the adult the school calls if a boarder is ill on a Sunday evening and a parent in Hong Kong cannot be reached. The adult who collects the boarder for half term, hosts exeat weekends, signs the consent forms the school requires within 24 hours, attends parents' evenings when the parents cannot fly, and acts as a host family during the breaks when the boarding house is closed.
Some families nominate a relative or close family friend in the country. This is permitted at many schools provided the nominated adult meets the school's eligibility criteria (over 25, no criminal record, a stable residence, capacity to host the child). Most families, however, retain a professional guardian agency, because the relative model often breaks down at the first half term when uncle and aunt suddenly need to take a week of leave for a child they barely know.
Who must have a guardian
The requirement applies to children under 18 whose parents are not resident in the country where the school is located. In the UK this covers the vast majority of international boarders. The Independent Schools Inspectorate, the Boarding Schools' Association and the school's own admissions policy will each require the family to nominate a guardian as a condition of accepting the offer. Most schools will not release the place until the guardian is named and the agency confirmed.
For students aged 18 and over, the requirement falls away in most jurisdictions, although schools still typically encourage a host family or local contact for practical reasons (exam stress, travel logistics, emergency support during sixth form). For boarders aged 16 and 17, schools remain firm on the guardian requirement even though some of those students will turn 18 during the academic year.
Where one parent is resident in the country and one parent is overseas, the resident parent satisfies the requirement. Where both parents are overseas, even temporarily for a posting, the requirement applies for the full duration of the parental absence. Our companion piece on the right age to start boarding covers the related developmental questions.
AEGIS and the UK framework
The Association for the Education and Guardianship of International Students (AEGIS) is the recognised accreditation body for UK guardianship agencies. AEGIS maintains a published list of accredited members, audits them every three years, and operates a complaints process. The body emerged in the late 1990s in response to a series of well documented welfare incidents involving boarders placed with unaccredited hosts.
Most leading UK boarding schools require, as a matter of policy, that international boarders use an AEGIS-accredited agency. A growing number now go further and maintain a school-approved list of two to four agencies they trust, asking families to select from within that list. The school's reasoning is straightforward: AEGIS accreditation is a useful baseline, but practical experience with a smaller panel of trusted agencies allows the school to manage the relationship more reliably.
The AEGIS standard covers vetting of host families, the qualifications and training of guardians and homestay hosts, safeguarding protocols, complaints handling, and standards for record keeping and communication with parents. Compliance is meaningful but not exhaustive; families should still meet the agency themselves before signing, not rely solely on the badge.
Talk to us before signing
Choosing a guardian agency is one of the few admissions decisions where the choice cannot easily be reversed mid-year. We help families understand the options and the questions to ask. The contact form reaches our editorial desk directly, and there is no commercial relationship between us and any guardianship agency. See also our student visa checker for the wider visa and welfare picture.
What guardians actually do
The day-to-day duties fall into four categories. The first is being the named emergency contact. When the school calls because a boarder is ill, injured or distressed and the parent cannot be reached, the guardian responds. In practice this might be a phone consultation with the school nurse, or a journey to the school to collect the child for a doctor's appointment, or a hospital visit if needed.
The second is hosting exeat weekends and half terms. Boarding houses close for half term and at end of term. Most schools also have exeat weekends within term when boarders are required to leave for two or three nights. A guardian or homestay host must be available to receive the child. The agency arranges either a stay at the guardian's family home or a placement with a vetted homestay family.
The third is administrative. The guardian receives the school's communications copied alongside the parents, signs consent forms within the school's time windows, attends parents' evenings where the parents cannot, and handles the routine paperwork that an in-country adult is best placed to handle.
The fourth is pastoral. A good guardian establishes a relationship with the child early, meets them at the start of term, calls or texts them through the year, and notices when something is not right. Pastoral care from a guardian sits alongside the school's pastoral structure, not in place of it. The guardian is a second adult ear, not a replacement for the housemaster.
Cost and service tiers
UK guardianship costs run from GBP 1,500 to GBP 8,000 per year, depending on the level of service. Three tiers are common.
Standard tier (GBP 1,500 to GBP 3,500)
Named guardian, 24-hour emergency contact, one or two host family placements per term for exeats and half terms, administrative support, end-of-term airport transfers. The minimum acceptable level for most schools.
Full service (GBP 4,000 to GBP 6,000)
Everything in standard plus regular pastoral check-ins, attendance at parents' evenings, support during exam periods, additional homestay weekends, more proactive communication with parents. The level most families choose for boarders in their early years at school.
Premium (GBP 6,000 to GBP 8,000 and above)
Bespoke service with dedicated personal guardian, frequent face-to-face time, full diary management, university application support in sixth form, additional travel and concierge arrangements. Used by a smaller subset of families, often those with multiple children or particular pastoral needs.
The premium tier is not always worth the additional spend. For most families the standard or full service tier is sufficient, particularly if the school has a strong pastoral structure of its own. Pay for service the school cannot provide, not duplication of service it already covers well.
How to choose a guardian agency
Five tests are worth running before signing. First, is the agency AEGIS-accredited and on the school's approved list. Second, has it operated for at least five years (newer agencies can be excellent, but track record matters disproportionately in a service where the worst case scenarios are rare and severe). Third, what is the guardian-to-student ratio. Agencies that overload guardians, often the cheapest, struggle to provide pastoral depth. Aim for ratios below 1:15.
Fourth, the homestay process. Ask how host families are vetted, how often they are re-vetted, whether the agency visits them in person, and whether the family will meet the host before the first placement. The host family network is the single most variable part of the service and the most worth scrutinising. Fifth, communication patterns. How often will the family receive updates. What is the protocol for emergencies. Who is the named guardian's deputy when the primary is away. The answers should be specific, not generic. For families considering a UK boarding move alongside a wider relocation, see our piece on UK boarding for international families.
Switzerland, Australia and the US
Switzerland operates a less formal framework. Most Swiss boarding schools assume the parents will be present in country for school events and do not require a formal guardian in the AEGIS sense; where parents are not resident, the school's own welfare staff usually fill the role. For families with one parent posted to a non-Swiss European location, this is workable. For families based fully in Asia or the Middle East, a Swiss agency-style guardian is still sensible. Our Swiss boarding piece covers the wider context.
Australia operates through the subclass 500 student visa framework. Boarders under 18 require either a parent on a guardian visa or a school-approved welfare arrangement, with the school taking on a more formal supervisory role than in the UK. The schools maintain their own panels of approved guardians and homestays. Our US boarding piece covers the American system, which uses an educational consultant or host family arrangement of broadly comparable function.
Red flags to watch for
Three patterns should give pause. Agencies that promise a single dedicated guardian per family at a heavily discounted price are usually overloading the actual guardian behind the scenes; check the published guardian-to-student ratio. Agencies that decline to share host family details in advance, or that arrange placements at very short notice without giving the family time to review, are not respecting the parental role. Agencies with consistently late or vague responses to administrative questions during the sales process will not improve once the contract is signed.
If the agency is unwilling to provide references from parents currently using the service, or to facilitate a conversation with another family at the same school, that is also a warning sign. Good agencies are confident in their service and welcome the reference call. The annual cost is significant and the alternative cost of a poor arrangement is significantly higher.

FAQ
Yes. Almost all UK, Swiss and Australian boarding schools require an in-country guardian for boarders under 18 whose parents live overseas. The guardian is the school's emergency contact and the child's host for exeats and half terms.
The Association for the Education and Guardianship of International Students. AEGIS is the recognised UK accreditation body for guardianship agencies. Most UK boarding schools require that the family use an AEGIS-accredited guardian organisation.
Standard guardianship packages cost GBP 1,500 to GBP 3,500 per year in the UK. Full service packages with multiple homestay weekends and 24-hour pastoral support run from GBP 4,000 to GBP 8,000 per year.
Some schools permit this, provided the family member is over 25, has a stable in-country residence and meets the school's other eligibility criteria. Many families nevertheless retain a professional agency for the operational reliability.
