Change of use to a state funded school under Part 3

State funded school permitted change of use sits in Part 3 of Schedule 2 to the General Permitted Development Order 2015, and it works as a prior approval right rather than an unconditional one. The class permits a change of use to a state-funded school or a registered nursery from a list of specified previous uses, and the local planning authority gets to assess a closed set of matters before the use can begin. It cannot refuse on design, on loss of the previous use, or on anything else outside that list.

That narrow scope is the whole value of the route. It is also where most applications come unstuck, because the four matters the authority can consider happen to be the four hardest things about putting a school into an existing building.

Read the current consolidated text before you rely on any of this. Part 3 was written against the pre-2020 use classes and has been amended several times since the Use Classes Order was rewritten in September 2020, so the list of qualifying previous uses in the version you remember may not be the list in force.

Which previous uses can change to a school

The class specifies the previous uses that qualify. Historically those included business and office premises, hotels, residential institutions, secure residential institutions, non-residential institutions and assembly and leisure uses, together with buildings in a mixed use including one of those.

The 2020 rewrite of the Use Classes Order folded most of those into Class E and Class F, and the Order has been amended to deal with the consequences, in places by reference to the classes as they stood before September 2020. The practical effect is that establishing whether your building qualifies is a two-stage exercise: identify the lawful use, then work out how that use is described for the purposes of the class as currently drafted.

Do not guess. Where the lawful use is uncertain, or where the building has been in a mixed or lapsed use, a certificate of lawfulness of existing use under section 191 of the Town and Country Planning Act 1990 is the foundation of everything that follows. There is a separate class covering agricultural buildings, which is a different route with different limits, and the same discipline applies there as to agricultural building prior notification under Part 6.

"State-funded school" is defined in the Order and covers schools funded wholly or mainly from public funds, which brings academies and free schools within it. An independent school does not qualify and needs a full planning application.

The prior approval matters the council assesses

The authority's consideration is limited to four matters: transport and highways impacts of the development, contamination risks on the site, flooding risks on the site, and noise impacts of the development.

The procedure matters as much as the substance. You apply for a determination as to whether prior approval is required for those matters, with the information the Order specifies. The authority has 56 days from a valid application to determine it, and where it fails to do so within that period the development may proceed in accordance with the application. It must also publicise the application, which gives neighbours a route to comment on the four matters, though not on anything else.

Three practical points. Serve the application with the technical evidence already in it, because an authority that has to ask for a noise assessment will issue a refusal rather than let the 56 days run out. Get the description right, including the number of pupils and the hours of operation, since those are the parameters the transport and noise assessments depend on. And keep a dated record of submission and validation, because the deemed approval provision turns entirely on when the clock started.

Transport, highways and the noise question

School traffic is concentrated into two short peaks and it is the issue that generates the most objection.

The transport evidence needs to deal with the arrival and departure profile rather than daily totals: drop-off and pick-up arrangements, whether any on-site set-down is proposed, queuing on the surrounding network, coach and minibus access where there is a catchment beyond walking distance, staff parking, cycle parking and the walking routes from the nearest bus stops. A school travel plan with modal share targets and a named travel plan coordinator is standard and is the thing a highway authority will ask to see.

Noise runs in two directions. Outward, the playground and any ball court generate impulsive noise during the day at levels that matter where the site adjoins housing, and the usual response is a combination of layout, acoustic fencing and restrictions on hours of use of external areas. Inward, classrooms have to achieve internal acoustic conditions suitable for teaching, which is governed by the published building bulletin on acoustic design for schools and becomes a design constraint on a site next to a main road or railway.

Address both in a single assessment with the methodology stated. An assessment that only looks outward invites a consultee holding objection, and one that only looks inward misses the neighbour amenity point entirely.

Contamination and flood risk considerations

A school is a sensitive end use and children are a sensitive receptor, so the assessment criteria applied to soil and ground gas are tighter than for a commercial occupier. Any former industrial or office site with a history of plant, fuel storage or made ground needs a desk study and, in most cases, intrusive investigation to the relevant British Standard with a remediation strategy where exceedances are found.

This is work for a suitably qualified and experienced practitioner. A professional is legally required for land contamination reporting of this kind, and an AI-assisted draft is a starting point for that professional rather than a substitute.

On flooding, educational establishments fall within the more vulnerable category in the flood risk vulnerability classification. In Flood Zone 2 that calls for a site-specific flood risk assessment. In Flood Zone 3a the more vulnerable classification brings in the exception test, which is a demanding thing to satisfy inside a prior approval timetable with a 56-day clock. If your building sits in Zone 3a, take advice before choosing this route over a full application.

Playing field provision and the consultee position

The class changes the use of the building. It does not create outdoor space, and the absence of a playing field is not one of the four matters the authority can consider, which produces the uncomfortable result that a school can be approved on a site with no external provision.

That does not make it a good idea. Area guidance for mainstream schools sets expectations for team game playing fields and informal social space, and the funding and registration process for the school will test them even where planning does not. Sport England is a statutory consultee where development affects playing fields, so a scheme that takes any part of an existing field is a different and much slower proposition.

Where outdoor space has to be formed, remember that hard surfacing, fencing, floodlighting and multi-use games areas are physical works outside the scope of the use change. New hard surfacing brings its own drainage requirement, in much the same way as the drainage condition attached to Class F hard surfaces does for a householder.

Temporary against permanent school use

Part 4 of Schedule 2 has carried a temporary provision allowing a state-funded school to occupy a building for a limited period, which is how a number of free schools opened while permanent premises were built or converted. The duration and the conditions attached to it have been amended, so read the current text rather than relying on the version in circulation.

The sequencing question is worth thinking through at the start. A temporary occupation buys time and gets pupils through the door, and it also establishes a traffic and noise pattern that neighbours will have formed a view about by the time you apply for anything permanent. Where the permanent scheme involves new buildings, that view becomes a material consideration.

Physical works that still need permission

The prior approval right is about use. Everything physical sits outside it:

• extensions, new buildings and modular classrooms, although separate rights exist in Part 7 for extensions to schools once the school use is established
• external alterations such as new entrances, window replacement and rooflights
• hard surfacing, car parking, drop-off loops and access alterations
• boundary treatment above the permitted heights, acoustic fencing and gates
• floodlighting and ball court enclosures
• signage, which is controlled under the advertisement regulations

Where any of that is needed, consider whether a single full application is simpler than a prior approval followed by three further applications. A Planning Statement that presents the use and the works together often gets a better officer response than a prior approval that leaves the authority to deal with the consequences piecemeal. The same trade-off arises with Class Q barn conversions and their qualifying date and limits, where the prior approval route is narrower than a full application but faster when it fits.
