Parent communication used to mean a paper letter in a book bag. Now it means an app, and schools have many to choose from. Tools for behaviour points and class photos. Tools for payments and trip consent. Tools that do a little of everything. The choice is harder than it looks. These apps differ on features. They also differ on something less obvious and more important. Where the pupil and parent data sits, and which country's law governs it. Under-16 online rules arrive in 2027. The line between an open consumer platform and a closed school tool will then matter more. This guide compares the main parent communication software and apps UK schools actually use, on features, payments, data protection and that emerging legal distinction.

Most of the confusion in this market comes from treating two different things as one. There is the class engagement app, designed for a teacher to share behaviour points, photos and quick updates with the parents of one class. Then there is the whole-school communications hub. The office uses it to message year groups, collect payments and consent, and book parents' evenings. It usually takes contact data straight from the MIS. ClassDojo and Seesaw sit in the first camp. IRIS ParentMail, School Gateway and Weduc sit in the second. A school choosing between them is often comparing tools that were never meant to do the same job.
Best for: Schools wanting communication, payments and forms in one UK-built platform that integrates with the MIS.
IRIS ParentMail, from IRIS Software Group, is used by over 3,000 schools and around a million parents. It connects to the major MIS products, including SIMS. It covers the whole office workload. Messaging in over a hundred languages. Online payments and dinner money. Trip and consent forms. Parents' evening booking. It is built for UK schools and UK compliance, which removes the data-residency question that comes with US platforms.
Best for: Schools already using ParentPay for payments who want communication in the same family of products.
School Gateway, from Schoolcomms, and Weduc are both part of ParentPay Group, the same group that owns the ParentPay payment platform and SIMS. The advantage is integration within one ownership group: payments, communication and, for SIMS schools, the MIS itself can sit closer together. Weduc leans towards a richer engagement app with newsfeeds and content; School Gateway is the more straightforward messaging-and-payments tool. For a school already committed to ParentPay, staying within the group reduces the number of separate contracts.
Best for: Primary classrooms wanting free, simple behaviour points and parent updates.
ClassDojo is widely used in UK primary schools and is free at the point of use, which is much of its appeal. It is strong on classroom culture: behaviour points, class stories, photos and quick teacher-to-parent messages. The trade-offs are important to state plainly. ClassDojo is a US company and stores data in the United States. It says it meets UK GDPR, and it offers a data processing addendum for schools. It relies on approved transfer routes, such as the UK extension to the EU-US Data Privacy Framework. That can be lawful. It still places pupil data under US jurisdiction beside UK law. The school is the data controller, so the school owns that decision. It is also a consumer engagement platform rather than a tool purpose-built around UK school administration or payments.
Best for: Primary schools focused on sharing pupils' learning and work with parents.
Seesaw overlaps with ClassDojo but tilts towards academic output: a pupil's work, learning journals and portfolios shared with families, rather than behaviour points. It too has a free tier and paid school plans, and it too is a US platform, so the same data-residency considerations apply. It fits a school whose first aim is to show parents what their child produces in class. It is not the tool for whole-school administration and payments.

A free app is rarely free of consequences. A school that adopts a US platform stays the data controller for the pupil and parent data in it. The school therefore carries the responsibility for the transfer abroad. It must also record why the arrangement is lawful. The Information Commissioner's Office expects a data protection impact assessment before adopting a tool that moves children's data overseas. None of this makes US apps unusable; many schools use them within the rules. It does mean the decision should be made with eyes open, recorded, and reviewed, rather than drifting in because a teacher liked the interface.
The UK government confirmed on 15 June 2026 that it will ban under-16s from social media. Regulations should reach Parliament by the end of 2026. The protections come into force in Spring 2027. The ban targets user-to-user platforms whose purpose is social interaction, the open networks. The government has been clear about the exemptions. The list will be narrow, and it will cover services such as education. Messaging services are not the target.
A closed app that a school uses to talk to its own pupils and parents is a different kind of service. It is not an open social network, and it sits inside that exempt group. The practical consequence is not panic but clarity: schools should know which side of the open-versus-closed line their chosen tools sit on. Regulators will treat these two kinds of tool differently. A school defends a tool that was built closed more easily than one it must argue into the exemption. We set out the wider case for the closed institutional model on the parent guide to the under-16 rules.
A bespoke system from ESRE removes the seam entirely, because the communication layer is not an app the school connects to its MIS. We build it on the engage.re graph. That is the same foundation that holds the school's pupils, attendance and payments. A first-day absence message, the attendance mark behind it and the payment for the next trip all attach to one pupil record. They are one set of data. All of it sits on UK servers the school controls. There is no nightly sync, because there are not two systems. There is no third party holding a copy of pupil data, because communication is simply a view onto the school's own.
That foundation matters most for talking to children, not just parents. Identity on the graph is real. A teacher is a confirmed teacher, and a parent is a confirmed parent. A child communicates through an account that a parent controls. The circle of contacts is closed to the people that parent has approved. The correct rules then follow from each child's confirmed age and country. The supervised experience is the default, and not a setting somebody switches on. The incoming under-16 rules favour that model. It is also why a school becomes a trusted route rather than a risk.
And the system keeps growing with the school. A new consent form, a new payment type, a new language, a whole new parent-facing workflow is added as data in days. The school can do this itself, from the documentation we hand over. An AI can follow it exactly. Nobody buys it as a vendor upgrade. The school owns the code outright, evolves it cheaply, and pays no per-parent or per-pupil renewal. The School Management Software hub describes the connected system. The guide to the under-16 ban for schools gives the argument about schools and the ban.
Every app on this page must answer one question. Which adult may see which child's information?
The answer is never simple. A pupil may have two parents at different addresses. There may be a step-parent with no legal responsibility, and a grandparent who collects on Tuesdays. A social worker may have a right to some records and not others.
Most systems express this as a role. A role describes a job, and each of these adults needs one permission on one record.
On engage.re a permission is a grant, and each grant names one action on one scope. A grant can narrow, and it can never widen. A withdrawal takes effect on the next call, so a change in a family arrangement does not wait for a support ticket.
Every access is also an event in a signed chain. A school can therefore show exactly who saw a record, and when.
We explain why a role is the wrong unit in what may an AI agent touch in your systems. We cover the custody question in data sovereignty in plain terms.
It depends on the job. IRIS ParentMail and the ParentPay Group apps suit payments, consent and parents' evening booking. They connect to the MIS, and they are built for UK schools and UK rules. ClassDojo and Seesaw suit simple class updates, and both are free at the basic tier. Both are US platforms, under US law as well as UK GDPR.
ClassDojo states it complies with UK GDPR and offers a data processing addendum, relying on approved international transfer mechanisms. It stores data in the US, so pupil data sits under US jurisdiction as well as UK law. Complete a data protection impact assessment before adopting any platform that transfers pupil data overseas.
The planned ban targets open user-to-user social platforms, and the government has said education services sit within a narrowly defined exemption. A closed app a school uses with its own pupils and parents is a different kind of service. The open-versus-closed distinction will carry more weight as the rules take effect in 2027.
Both models work. A separate app is quick and often free at the basic tier but adds a data silo and a login. Communication built into the MIS or a bespoke system keeps the message, the payment and the pupil record in one place. The right answer depends on whether communication is standalone or part of one connected operation.
