Most academy trusts don't start out thinking about modular construction at scale.

It usually begins with a space problem at one school. A growing intake. An ageing building that can't keep pace. A SEND unit that's been on the to-do list for two years. Someone googles modular buildings, makes a call, and a project begins.

Then it works. And suddenly the conversation changes.

That's the pattern we see repeatedly at Eco Classrooms & Nurseries. A single project becomes the proof of concept. The trust sees what's possible - the speed, the quality, the predictability - and starts thinking about what that could mean across the rest of the estate.

This guide is for both audiences: the trust director or CEO thinking strategically about estate expansion, and the school business director or estates manager who needs to understand the process, the costs, and how to make the case internally.

Why this matters now for academies and MATs

The academy sector is bigger than many people realise - and growing.

At January 2025, 83% of secondary schools in England were academies or free schools, accounting for 82.7% of secondary school pupils. At primary level, 46.1% of schools were academies, accounting for 47.3% of the primary school population. Over half of all pupils in England now attend an academy.

In 2024, the number of Multi-Academy Trusts with 10 or more schools increased by 21%, with further growth expected as DfE policy continues to favour consolidation and expansion. MATs are inheriting complex, ageing estates - each school with different layouts, different standards, and different needs.

At the same time, estates governance has moved firmly to board level. Trusts are now expected to own a structured estate strategy, underpinned by robust asset management plans and multi-year maintenance programmes - with estate decisions aligned to educational priorities including curriculum delivery, pupil capacity, sustainability and risk.

Modular construction sits squarely in the middle of that challenge. It is faster than traditional construction, more cost-predictable, and - critically for MATs managing multiple sites - highly consistent in quality and process.

The three objections MATs typically raise

In our experience, the questions that come up most often from academy trusts considering modular buildings are about cost, planning, and consistency. Here is an honest answer to each.

"Is modular actually cost-effective for us?"

Yes - and the case is stronger at trust level than it might appear at school level.

A small to medium modular school building (50-150m²) typically costs between £100,000 and £300,000, including passive design, natural ventilation, manufacture, delivery and installation, but excluding VAT and professional and planning fees.

Compare that to a traditional build equivalent, which would take two to three times as long, involve far greater site disruption, and carry significantly more cost uncertainty. Because so much of the build happens off-site, there are fewer variables like weather delays and labour overruns, making modular far easier to budget with confidence.

For a MAT managing multiple sites, the predictability matters as much as the headline price. A building that costs what it was quoted, arrives when it was scheduled, and requires no costly remediation is a better use of capital than a cheaper quote that overruns. The whole-life cost picture reinforces this: high-performance insulation and airtight SIPs construction can cut heating costs by 20-30% across every building in the estate.

"What about planning - is it more complicated across multiple sites?"

No more complicated than any other construction method - and in some respects simpler.

Modular buildings go through exactly the same planning process as traditional builds and are treated identically by planning authorities. Being modular does not make planning harder, slower, or less likely to succeed. What matters to a planning authority is the size, appearance, and impact on the surrounding area - not how the building was made.

For a MAT with sites across multiple local authority areas, each site will require its own planning application. That is no different from traditional construction. The advantage with modular is that the design and planning stage happens while manufacturing is being prepared, so the overall programme is compressed rather than sequential. For more detail on how planning works: do modular buildings need planning permission?

"Can you deliver a consistent standard across different sites?"

This is the right question - and one that matters most to trust-level decision-makers.

Inconsistency across the estate is one of the most common challenges growing MATs face. Many trusts are operating with disconnected, outdated, or inconsistent physical environments - a serious barrier for a trust trying to deliver a unified education strategy.

Every ECAN building is bespoke - designed around the specific site, the school's needs, and the people who will use it. But bespoke does not mean inconsistent. The construction method, materials, performance standards, and quality of finish are the same across every project. A trust working with ECAN across multiple sites gets buildings that feel coherent and reflect the same values, even where site constraints and layouts differ.

How it works in practice: from single site to multi-site

Here is how a typical MAT relationship with ECAN develops.

It starts with one school. A trust identifies a space need at one of its schools - a new classroom, a SEND unit, an early years expansion. They commission a single modular building, working through ECAN's standard process from initial consultation and site visit through design, planning, manufacturing, and installation.

The process is straightforward. Modular builds are typically delivered in 12-24 weeks from start to finish - compared to 9-18 months for a traditional build. In many cases, schools can have a new space ready within a single term. The trust sees a predictable timeline, minimal disruption to a live school site, and a building that performs well from day one.

The conversation grows. Once the trust has confidence in the process and the product, it is natural to start thinking about other sites with similar needs. At that point, ECAN can work at trust level - understanding the broader estate picture, identifying sites with similar requirements, and delivering a coherent programme of works rather than a series of one-off projects.

What types of buildings can MATs commission?

ECAN builds across the full range of educational spaces relevant to academy trusts:

Additional classrooms and teaching blocks. Whether a primary school needs one extra classroom or a secondary needs a new teaching wing, modular construction delivers permanent, high-quality space at pace. See our modular classroom buildings page for more.

SEND units and inclusion bases. Demand for on-site SEND provision is rising sharply. The government has set aside £740 million to help build specialist provision in mainstream schools - and modular is well-suited to delivering the acoustic control, sensory-considered design, and accessible layouts that SEND spaces require. Read more in our guide: modular classrooms for SEND.

Nursery and early years buildings. For trusts with primary schools or nursery provision, modular nursery buildings can be delivered to the same permanent, high-specification standard as classroom buildings. See our full guide: modular nursery buildings: costs, timelines and what to expect.

Multi-use buildings. Staff rooms, admin spaces, community hubs, and multi-use teaching buildings are all deliverable within a modular framework.

Funding for academy trusts and MATs

There are several funding routes relevant to academies and MATs considering modular buildings.

Condition Improvement Fund (CIF). CIF is available to standalone academies or MATs with fewer than five academies or fewer than 3,000 pupils. It is an annual competitive bidding round with priority given to condition, health and safety, and energy efficiency projects.

Schools Condition Allocation (SCA). Larger MATs receive SCA directly - a capital allocation based on the size of the trust's estate, to be deployed strategically across sites.

High Needs Capital Funding. For SEND-specific buildings, this is the relevant funding stream. £1 billion of the 2025-26 UK Budget has been earmarked specifically for high needs and SEND - a significant pot for trusts with identified specialist provision needs.

The estate strategy angle

For trust directors and CEOs, the case for modular is not just about individual buildings - it is about what a consistent, planned approach to the estate makes possible.

The DfE's estate strategy signals a move away from fully competitive bid processes towards improved condition data and standardised reporting - which means trusts with a clear, proactive estate plan are better positioned for funding and better protected against regulatory scrutiny.

Modular construction supports that approach. A building programme that is predictable in cost, fast in delivery, and consistent in quality allows a trust to plan its estate with confidence - rather than reacting to crises one school at a time.
