Evidence base for a school expansion on a playing field

A school expansion that takes any part of a playing field brings two consent regimes into play, and most project teams only plan for one. Planning permission is the obvious one, with Sport England consulted as a statutory consultee. The second is consent from the Secretary of State for Education under section 77 of the School Standards and Framework Act 1998, which is needed before school playing field land is disposed of or changed to another use. Neither consent substitutes for the other, and the section 77 process has its own timetable.

Start both conversations before the design is fixed. A classroom block sited across the corner of a pitch is far harder to move at planning stage than at feasibility stage.

Sport England as a statutory consultee

The procedure order requires local planning authorities to consult Sport England where development is on land that is or forms part of a playing field, where the land was last used as a playing field within the previous five years, or where the land is allocated for use as a playing field in a development plan.

That is wider than people expect. A scrubbed-over field that has not been marked out since 2022 is caught. A grassed area between the hall and the boundary that has never hosted a fixture may still be part of the playing field for these purposes, because the test is about the field rather than the pitch.

Sport England's response carries real weight. An objection from a statutory consultee on a school site is rarely overcome at committee without either a design change or an agreed package of replacement provision, and officers know it.

The playing field exception tests

Sport England assesses proposals against its playing fields policy, which allows development only where one of a small number of exception circumstances is met. In substance those exceptions cover land that is incapable of forming a playing pitch and where use of the remaining field is unaffected, replacement of the affected land by provision of equivalent or better quality, quantity and accessibility, a small area needed for facilities ancillary to the use of the site as a playing field, and new sports facilities whose benefits outweigh the loss. Read the policy for the precise wording of each, because the exception you rely on determines the evidence you must produce.

The evidence that answers a replacement case:

• A pitch layout drawing showing the existing marked pitches, the pitches lost and the pitches after development, with run-offs and orientation.
• A quality assessment of both the existing and the replacement land, covering drainage, levels, surface, goal provision and changing facilities.
• Playing field area calculations against the school premises regulations and the area guidelines for mainstream schools, showing the school still meets the team-game area requirement for its roll.
• A curriculum statement from the school on how physical education will be delivered during and after the works.
• Any community use agreement affected, because out-of-hours community access is part of accessibility.

A replacement that is smaller, wetter or further away will not pass, however well it is drawn.

Separate consent for school playing field land

Section 77 consent is administered by the Department for Education, not by the council, and it applies to disposal and to change of use of school playing field land. Applications are made by the school or the local authority as landowner, and the department expects to see how the proceeds or the replacement provision benefit sport and education at the school.

Two practical points. The section 77 process runs on its own timescale and should be started in parallel with the planning application, not after it. And the two submissions must tell the same story about the area of field lost and the replacement provided, because inconsistency between them is noticed.

Travel plan and the school run

The transport case on a school expansion is about the peak fifteen minutes twice a day in term time. Nothing else on the site produces that pattern.

A Transport Assessment for an expansion needs an existing baseline from a school gate survey, a mode share for current pupils and staff, the trip generation for the additional roll, and a realistic modal shift target rather than an aspirational one. Where the site is on a classified road, the highway authority will focus on queueing at the access and on informal parking on the approach streets.

The measures that work, in roughly the order councils accept them:

1. Staggered start and finish times between year groups or between phases, which flattens the peak more than any other single measure.
2. A drop-off loop within the site with a one-way circulation and enough length to hold the queue, or a formal park-and-stride arrangement with a named car park.
3. Secure covered cycle and scooter parking sized to the target, not to current use.
4. Pedestrian crossing improvements, a school street closure at the gate, and footway widening on the main approach.
5. A Travel Plan with named responsibilities, annual surveys, a monitoring fee and a review trigger if targets are missed.

Active Travel England is a statutory consultee for larger major applications, and the thresholds should be checked against the current procedure order before you assume it is not involved.

Noise from play and from plant

Three sources, three different assessment approaches, one document.

Noise from children at play is the most contested and the least standardised. There is no British Standard written for it, so the assessment usually measures a comparable school, presents levels at the nearest residential facades and discusses character rather than applying an industrial rating method uncritically. Where a multi-use games area with a hard surface and fencing is proposed close to houses, expect an objection and design for it: position the games area away from the boundary, use acoustic fencing, and accept hours conditions.

Plant noise is conventional and is assessed under BS 4142:2014+A1:2019. Air source heat pumps, kitchen extract and ventilation plant on a new block are the usual sources.

Construction noise sits under BS 5228, and on a school site the receptors include the school's own classrooms. A Noise Impact Assessment that covers neighbours but ignores the examination hall 15 metres from the piling rig has missed the point.

Daylight, ventilation and overheating in teaching spaces

New teaching accommodation is assessed against the education guidance on ventilation, thermal comfort and indoor air quality, which sets overheating criteria for schools, and against daylight standards for learning spaces.

The tension is familiar: large windows for daylight, solar gain from those windows, and a ventilation strategy that cannot rely on open windows where the classroom faces a busy road or the playground. Resolve it with the Overheating Risk Assessment at design stage rather than at building regulations stage, because the fix is usually external shading or a change in orientation, and both affect the planning drawings.

Illustrative example

A two-form entry primary school adds a six classroom block on the corner of its field, taking 0.15 hectares. The replacement case provides a re-graded and drained area of 0.2 hectares at the other end of the site, with a new mini-pitch marked out and improved changing access. Playing field area after development still meets the team-game requirement for the increased roll. These figures are illustrative and every school site turns on its own area calculations.

Trees, ecology and biodiversity net gain

School fields are usually species-poor grassland with mature boundary trees, which produces a predictable pattern: low habitat value on the field, high value on the boundary, and a biodiversity metric that is easy to satisfy on paper and hard to satisfy on a site with no spare land.

Where on-site gain is not achievable, the options are off-site units or statutory credits, both of which need budgeting early. The statutory metric should be completed by a competent person under the Environment Act 2021 regime and the biodiversity gain plan approved by the authority after permission.

Boundary trees need a survey to BS 5837:2012, and playground construction inside a root protection area needs a no-dig specification and arboricultural supervision.

Phasing around the academic year

The programme is a planning matter on a school site because the construction management plan is conditioned. Build the phasing into the application rather than leaving it to discharge.

What the plan should address: which works happen in the summer holiday, how construction traffic is separated from pupil arrival, the hoarding line and the safeguarding arrangements, where temporary accommodation sits and for how long, how the field remains usable for physical education during the works, and the delivery window that avoids the school gate peak. Community uses in a residential setting raise the same operational questions, as set out in which reports a day nursery in a residential street needs.
