Making a Formal Complaint About School SEN Provision: When and How

A formal complaint is a specific legal process, not just an expression of dissatisfaction. Understanding when to use it, and how, makes the difference between a complaint that changes things and one that goes nowhere.

⚖️

This guide explains the legal framework and what you need to know. When you are ready to write the actual letter, SEN Letters UK generates it for you.

For many parents, the word "complaint" feels uncomfortable, as though it implies an adversarial relationship with the school. But a formal complaint is simply a structured process for raising a concern that has not been resolved through other means. It is not the end of a relationship. It is a mechanism that creates accountability.

Understanding when to use it, and how to use it effectively, is a significant part of navigating the SEND system.

When a formal complaint is appropriate

A formal complaint is appropriate when a concern has been raised and has not been resolved through informal channels. That might mean a letter to the SENCO that was ignored, a meeting that resulted in commitments that were not followed through, or a pattern of provision that falls short of what the school is legally required to provide.

A formal complaint is also appropriate when you need a documented record of having raised a specific issue, for example, before escalating to the local authority or before making a request for an EHC assessment.

What a formal complaint is not: it is not the right mechanism for challenging local authority decisions (those go through mediation and the tribunal), and it is not a substitute for legal routes where they exist.

Every school must have a complaints procedure

Under the Education (Independent School Standards) Regulations 2014 and equivalent regulations for maintained schools, all schools must have a formal complaints procedure. This procedure must be published on the school's website. If you cannot find it, ask the school office for a copy.

The procedure typically involves two or three stages: informal resolution (usually with the headteacher), a formal stage with a panel or senior leader, and in some cases a review by the governing body. The school is required to respond at each stage within set timeframes, typically 20 to 25 working days.

What makes a complaint effective

An effective formal complaint is specific, factual, and documented. It sets out exactly what happened and when, precisely what provision was agreed or required but not provided, any previous attempts to resolve the matter and their outcomes, and the specific outcome the complaint seeks.

A complaint that is written as an emotional expression of frustration is easier to handle dismissively. A complaint that reads as a detailed, documented account of a specific failure, with reference to the school's obligations under the SEND Code of Practice and the legal duties under the Children and Families Act 2014, is significantly harder to ignore.

Copying in the right people

The formal complaint letter should be addressed to the headteacher. For serious matters, or if the headteacher has already been involved and been unresponsive, address it to the chair of governors and copy in the headteacher.

For maintained schools, you may also consider copying in the local authority's SEN team, particularly where the complaint concerns provision that the local authority has a duty to monitor.

If the school's complaints process fails

If you exhaust the school's complaints procedure without resolution, there are two further routes. The first is the local authority. The local authority has a duty to monitor schools' implementation of the SEND Code of Practice, and a complaint to the SEN team about a specific school's failures can prompt intervention.

The second, for serious failures involving the local authority itself, is the Local Government and Social Care Ombudsman. The Ombudsman investigates complaints about local authorities and can require remedial action and compensation.

For situations where the issue is not just the school's failure but the adequacy of an EHC plan itself, the First-tier Tribunal remains the primary appeal mechanism.

Documentation

Throughout the complaints process, keep copies of everything. Note dates, retain emails, and follow up verbal conversations with a brief written summary sent by email. This documentation becomes your evidence if the matter escalates.

The formal complaint letter

A well-constructed formal complaint letter makes clear from the outset that it is a formal complaint under the school's statutory complaints procedure, sets out the grounds clearly and specifically, and states the outcome sought. SEN Letters UK generates formally worded complaint letters that meet these requirements and reference the school's legal obligations throughout.
