A SEND System Under Strain and an Uneven Burden on Schools

The headline should be familiar at this point: England’s SEND (Special Educational Needs and Disabilities) system is under pressure, with the UK media using phrases like ‘never before seen’ and ‘unprecedented’ regularly to describe the situation. But behind the national nervousness lies a pattern of anomalies that receives far less attention – and it has huge implications for how schools operate, plan, and support their pupils. 

Newly published NFER (National Foundation for Educational Research) research shows that pupils with special educational needs and disabilities are not evenly spread across England’s mainstream schools. Far from it, in fact. 

Instead, there’s a large and genuinely problematic imbalance – some schools are educating far more pupils with SEND than would be expected from their local intake. Some leaders describe becoming “victims of their own success”: schools that champion inclusion attract more families looking for support, but without the funding, space, or resources needed to sustain that commitment.

This unevenness isn’t a distant policy issue. It shapes budgets, space planning, staffing models, parental expectations, behaviour management, and the daily reality of running a truly inclusive school. And for school leaders, it increasingly raises one unavoidable question: how do you adapt your physical environment quickly enough to keep up?

The Steady Rise of SEND Students

Across the UK, more children than ever are being identified with SEND. The numbers themselves are striking:

• 1 in 5 pupils in mainstream settings now has SEND – that’s more than 1.7 million children.
• The number of pupils with an Education, Health and Care Plan (EHCP), which is for those with the highest level of need, has nearly doubled, rising from 2.8% to 5.3% since 2015/16.
• Schools are reporting not only more pupils with additional needs but also more complex needs, more personalised interventions, and greater pressure on specialist spaces and staff.

But what we’re really looking at today is what sits beneath these increases:

The Uneven Distribution of SEND Pupils

The NFER’s latest interim report makes it clear that the rise in SEND pupils is not shared evenly across schools. Instead, here are the key statistics that outline the reality:

• In the top quartile of primary schools, EHCP (Education, Health and Care Plans) pupils are six times more common than in the lowest quartile.
• In secondary schools, the gap is around fivefold.
• Many mainstream schools now need to look more like specialist settings – without the specialist spaces or staffing usually associated with them.

This skewed concentration means that the schools with the strongest reputations for inclusion are carrying a significantly heavier operational load. Their classrooms fill faster. Intervention and therapy spaces are stretched thin. Staff spend more time delivering individualised support in rooms never designed for it. And estates reach their limits far sooner than planned.

 

“The findings highlight what we have known for years, which is that some schools actively avoid admissions from Send students.” (Daniel Kebede, general secretary of the National Education Union)

 

Importantly, more than half of pupils with EHCPs are now educated in mainstream schools – and that percentage will just continue to rise. And when those pupils tend towards the schools already known for their SEND capabilities, instead of evenly spreading between public schools, the strain deepens.

As NFER researchers and school leaders have consistently noted, uneven distribution isn’t a statistic – it’s lived experience. It influences every operational decision, from timetabling to mental health support, from behaviour policies to how many quiet spaces a school needs. 

 

The Practical Impact on School Estates

When SEND numbers rise unevenly, the first pressure point is generally on the school estate. Schools with a disproportionately high intake of SEND students tend to experience:

1. Spaces that aren’t Designed for SEND Needs

Traditional classrooms frequently lack breakout rooms, sensory-safe environments, calm regulation spaces, and small-group teaching areas – precisely the spaces many SEND pupils rely on to engage with learning.

2. Overcrowding and Inflexible Layouts

Rooms not designed for high-SEND learning often have poor acoustics, harsh lighting, limited storage for specialist equipment, and too little space for movement. This places additional strain on staff, who are expected to differentiate in environments that actively work against them.

3. Pressure on Specialist Provision

In schools with more SEND students than their space is set up for, problematic bottlenecks quickly form. Accessing therapy rooms, intervention spaces, and other accessible facilities in the moments when they’re needed becomes harder, delayed, or impossible.

The result? Timetabling challenges, long waits for interventions, and staff constantly reallocating rooms not intended for that purpose.

 

A Growing Urgency for Smarter Space Solutions

For schools supporting disproportionately high SEND populations (and doing it well), the issue is no longer just staffing or funding. It’s time.

EHCP numbers are not expected to fall, and distribution is unlikely to rebalance naturally. And traditional building moves far more slowly than SEND demand is rising.

Inclusive practices need inclusive spaces. Growing SEND numbers need additional capacity. And uneven distribution means many schools simply cannot wait years for new facilities.

This is where modular SEN / SEND school buildings can step in as a uniquely effective solution.

Modular Classrooms: Designed for Inclusion, Delivered Fast

Here at PF Modular, we specialise in purpose-built modular classrooms and facilities with SEND pupils’ needs at the centre. These structures aren’t just “extra rooms” – they are carefully considered environments designed to support inclusion, learning, and well-being. Key advantages of modular learning spaces include:

Rapid Delivery

Modular buildings can be designed, built, and installed in a fraction of the time of traditional construction, minimising disruption to students and staff. This is crucial for schools facing urgent space shortages – particularly those with sharply rising high-SEND populations.

 

Note: To find out more about the speed of modular classroom construction, read our dedicated blog on the topic. 

Flexible, Tailored Interiors

There is a lot of differentiation in SEND settings. PF Modular’s solutions can be customised to include:

• Quiet/sensory rooms
• Small-group teaching spaces
• Therapy and intervention zones
• Accessible WC and changing facilities
• Calm, acoustic-optimised learning environments

This design flexibility supports the diverse learning and well-being needs of SEND pupils – from those with autism spectrum conditions to pupils with social, emotional, and mental health needs.

Built for Everyday School Life

Modular buildings meet the same performance standards as traditional builds, offering effective insulation, ventilation, acoustics, and durability. They’re also made to integrate seamlessly with existing buildings while maintaining high comfort and accessibility standards.

Note: To read more about how modular compares to traditional construction, check out our blog on the topic.

 

One recent example of the usefulness of these benefits is PF Modular’s work with Salutem Care & Education, where a bespoke SEN classroom was delivered to support pupils with complex needs. Rather than adapting standard teaching spaces, the project focused on creating calm, flexible environments that support small-group learning, regulation, and staff visibility – reflecting the reality of day-to-day SEND provision.

Future-Proofing Schools in a Changing SEND Landscape

For headteachers, MAT leaders, and local authority estates teams, the challenge is no longer whether SEND pressures will change, but how quickly they can respond.

With major SEND reforms expected from government policymakers and continued pressure on mainstream inclusion, schools need infrastructure strategies that are agile, scalable, and future-ready.

Modular buildings from PF Modular offer a way to:

• Quickly expand capacity in response to shifting school populations
• Create purpose-designed areas that prioritise pupil needs
• Support inclusion without sacrificing teaching quality or school culture
• Offer a cost-effective alternative to lengthy traditional builds

For high-SEND schools already carrying a disproportionate burden, these solutions aren’t optional extras. They are essential tools for delivering inclusive education that works – not just today, but in a SEND landscape defined by ongoing change.
