Building a new school is one of the largest capital investments a local authority, academy trust or government department can undertake. But putting a single price on a school building is difficult.

A relatively straightforward primary school on an accessible site is a very different construction project from a large secondary school with science laboratories, sports facilities and specialist teaching spaces. SEND provision can introduce another level of complexity, while location, ground conditions, energy requirements and the need to work around an existing live school can all have a significant effect on the final bill.

As a broad guide, current UK construction cost data suggests that new school buildings commonly fall somewhere around £2,200 to £2,900 per square metre, before considering the significant variation that can exist between individual projects.

Costmodelling, which publishes UK building cost benchmark data, currently places primary and junior schools at around £2,500–£2,780 per m², secondary and middle schools at approximately £2,600–£2,880 per m², and special schools at around £2,620–£2,900 per m².

These figures are useful as an early benchmark, but they should not be confused with the total amount ultimately spent delivering a new school.

How much does it cost to build a school in the UK?

For anyone asking how much does it cost to build a school?, the most accurate answer is that the size of the building is only the starting point.

Indicative current construction benchmarks are:

School type Indicative construction cost
Primary or junior school £2,500–£2,780 per m²
Secondary or middle school £2,600–£2,880 per m²
Special school £2,620–£2,900 per m²
Nursery school £2,600–£2,880 per m²
Sixth-form college £2,470–£2,750 per m²

Source: Costmodelling UK building cost benchmarks. Figures should be treated as indicative rather than project quotations.

On paper, that means a 3,000m² primary school could have a headline construction value in the region of £7.5 million to £8.3 million based purely on those benchmark rates.

However, real projects can cost substantially more once external works, utilities, site preparation, professional fees, furniture and equipment, landscaping, contingency and other project-specific costs are included.

Recent real-world schemes demonstrate the point.

Kent County Council, for example, reported in June 2025 that the new building delivered for More Park Catholic Primary School in West Malling cost £11 million, funded through the council’s Basic Needs programme.

Elsewhere, a cost review produced in 2025 for a proposed primary school at Chilmington in Kent considered comparable BCIS construction rates ranging from approximately £1,785 to £2,466 per m² at first-quarter 2025 prices. The proposed project budget itself was considerably higher on a per-square-metre basis, illustrating the difference between basic construction comparisons and complete project budgets.

There is therefore no universally reliable answer such as “a new primary school costs £8 million”. Two schools with the same pupil capacity can end up with dramatically different final budgets.

New school construction project in the UK

What determines school building construction costs?

One of the biggest influences is simply what the building needs to contain.

A typical primary school requires classrooms, administrative areas, kitchen and dining space, toilets, staff facilities and halls. A secondary school introduces considerably more specialist accommodation.

Science laboratories require specialist services and ventilation. Design and technology facilities may require additional electrical infrastructure and extraction. Sports halls involve large structural spans, while performance spaces, commercial kitchens and specialist ICT rooms all add complexity.

External events can also move construction budgets surprisingly quickly. School Building recently examined how geopolitical tensions could increase UK school construction costs through higher energy, material and logistics prices.

That helps explain why secondary school construction costs tend to sit slightly above typical primary school costs.

Location matters too.

A school being constructed on a straightforward greenfield site with good access can be considerably easier to deliver than one squeezed onto a constrained urban plot.

London and the South East can also attract higher labour, logistics and preliminaries costs, while remote locations can create their own supply-chain challenges.

Ground conditions can be particularly significant. Contamination, poor soil conditions, drainage problems or the requirement for extensive piling may add millions of pounds to a large education scheme before much of the visible building has even been constructed.

This is why cost per square metre should always be viewed as a useful benchmarking tool rather than a fixed price.

Why SEND schools can cost more to build

One of the most significant areas of education estate development over the coming decade will be SEND provision.

Special schools and specialist spaces within mainstream schools often need considerably more floor area per pupil than conventional classrooms.

Design may need to incorporate therapy rooms, sensory spaces, accessible hygiene facilities, specialist changing rooms, quiet spaces and additional circulation areas.

Acoustics, lighting, ventilation and external spaces can also require particular attention.

Costmodelling currently puts special-school construction at approximately £2,620–£2,900 per m², slightly above its equivalent primary-school benchmark.

The scale of forthcoming investment makes this an increasingly important part of the education construction market.

The Department for Education’s Education Estates Strategy, published in February 2026, commits at least £3.7 billion in high-needs capital funding between 2025-26 and 2029-30.

The government says that investment will help create 60,000 additional specialist places, alongside improvements designed to make mainstream schools more accessible and inclusive.

That does not mean all of the investment will be spent constructing entirely new special schools. A significant proportion will support inclusion bases, adaptations and additional specialist capacity within existing education estates.

However, it does suggest SEND construction and refurbishment will remain one of the most active areas of the school building sector.

Modern UK school building under construction

Construction cost is not the same as total project cost

This is perhaps the most important distinction when discussing how much building a school costs.

The headline construction contract is only one part of the overall development.

A project may also need to pay for land, surveys, planning, architectural and engineering services, project management, utility connections, demolition, temporary accommodation, external works, furniture and equipment.

There may also be substantial contingency allowances.

Imagine, for example, that an existing school needs to remain operational while a replacement building is constructed on the same site.

Temporary classrooms may be needed. Construction access needs to be separated safely from pupils. Works may have to be phased around school operations, and the existing building may eventually need to be demolished.

That is fundamentally different from handing a contractor an empty and fully serviced site.

It is therefore important when comparing reported school costs to understand exactly what the figure includes.

One figure may represent the building contract alone, while another may represent the complete capital budget.

Without that context, comparisons between school projects can be misleading.

New school or rebuilding an existing one?

Not every area requiring better educational facilities needs an entirely new school.

For some estates, refurbishment and extension can provide better value. For others, the condition of the existing buildings means replacement becomes the more sensible long-term option.

This question sits at the heart of the government’s current School Rebuilding Programme.

As of June 2026, the Department for Education says there are 524 projects within the programme. Schools are prioritised on factors including severe condition issues, particular construction types requiring replacement and buildings presenting risks to pupils or staff.

These schemes do not necessarily involve flattening an entire school and starting again.

Some projects involve replacing individual blocks or major refurbishment, while others require much more extensive rebuilding.

Working with an existing school estate can save money by retaining usable buildings and infrastructure, but it can also make construction more complicated.

Phasing, temporary accommodation and maintaining safe access for pupils can all increase project costs.

There is therefore no simple rule that refurbishment is always cheaper than new build.

The correct decision depends on the building’s condition, future maintenance liabilities and how suitable the existing estate is for modern teaching.

New primary school construction and development

Can modular construction make schools cheaper?

Modern methods of construction have played a growing role in education.

Manufacturing significant elements of a school away from the construction site can reduce the amount of work taking place in a live school environment and, in the right circumstances, shorten programmes.

Standardisation can also create efficiencies where similar designs are repeated.

But modular does not automatically mean cheap.

Foundations, utilities, groundworks, planning, professional fees and external works are still required. The building must also meet exactly the same expectations around education, fire safety, accessibility, acoustics and durability.

The biggest benefits can therefore be programme certainty and quality control rather than simply achieving the lowest possible cost per square metre.

For a project where an existing school needs additional capacity quickly, that time saving may itself have considerable value.

How long does it take to build a school?

The physical construction of a school may take somewhere around a year to two years depending on its scale and complexity, but the overall development process can be considerably longer.

Before work starts, a project needs to progress through feasibility, design, planning, surveys, procurement and pre-construction.

Complex projects can then require phased handovers or demolition after the new building has opened.

This means the journey from identifying the need for a school to pupils entering the completed building can run over several years to some projects that are finished in months.

Planning early is particularly important in areas experiencing substantial housing development, where pupil demand can rise rapidly once homes become occupied.

Secondary school building construction in the UK

So, how much does building a school cost?

As a starting point in 2026, a figure of roughly £2,500 to £2,900 per square metre provides a useful indication for many mainstream UK school construction projects, based on current published construction benchmarks.

But it should only ever be viewed as a starting point.

A relatively straightforward primary school may ultimately cost several million pounds, while a large secondary school or complex SEND project can easily move into tens of millions.

Site conditions, building size, specification, regional labour costs, specialist facilities and the amount of external infrastructure required can all dramatically change the final figure.

Perhaps most importantly, anyone comparing school building costs needs to establish whether they are looking at the cost of constructing the building or the cost of delivering the complete project.

Those two numbers can be very different.

With £38 billion of education capital investment planned between 2025-26 and 2029-30, and hundreds of projects already progressing through the School Rebuilding Programme, understanding those costs is set to become even more important for schools, local authorities, designers and contractors over the coming decade.

 

Frequently asked questions

How much does it cost to build a school in the UK?

Current UK construction benchmarks suggest that many school buildings sit somewhere around £2,500 to £2,900 per square metre, although the total project cost can be considerably higher. Location, school type, site conditions, specification and specialist facilities all affect the final budget.

How much does it cost to build a primary school?

Primary-school construction benchmarks are currently around £2,500 to £2,780 per square metre according to Costmodelling. A complete new primary-school project can therefore cost several million pounds and may exceed £10 million depending on its size and requirements.

How much does it cost to build a secondary school?

Published UK benchmarks place secondary-school construction at approximately £2,600 to £2,880 per square metre. Because secondary schools are generally much larger and require specialist spaces such as laboratories, sports halls and technology rooms, complete project budgets can run into tens of millions of pounds.

Why are schools expensive to build?

Schools are technically complex public buildings designed to be used intensively for many decades. In addition to classrooms, they may require sports facilities, kitchens, specialist teaching rooms, significant mechanical and electrical systems, external areas and extensive safety and accessibility measures.

Are SEND schools more expensive to build?

They can be. SEND environments often require more space per pupil and specialist facilities including therapy rooms, accessible hygiene areas, sensory rooms and additional circulation space. Current published benchmarks put special-school construction slightly above mainstream primary-school rates.

Is renovating a school cheaper than rebuilding it?

Sometimes, but not always. Retaining a sound structure can reduce construction requirements, while major structural problems, outdated services or extensive phased works can make refurbishment expensive. Whole-life value rather than simply initial construction cost should be considered.

Who pays for new schools?

Funding can come from several sources including the Department for Education, local authorities and developer contributions associated with major housing schemes. The government’s current Education Estates Strategy includes billions of pounds for mainstream and specialist school places alongside the School Rebuilding Programme.

How many schools are currently in the School Rebuilding Programme?

As of June 2026, the Department for Education reports that 524 projects have been included in the School Rebuilding Programme since it began in 2021.
