Office to nursery: moving from E(g)(i) to E(f)

Changing an office to a day nursery is a move from Class E(g)(i) to Class E(f) of the Town and Country Planning (Use Classes) Order 1987 as amended, and a move within Class E is not development. No planning application, no fee, no eight week wait for the use itself. What the council can still control is everything physical and everything about how the nursery operates at the boundary: the works to the building, the play space, the access, the parking and the noise.

Operators who read the first paragraph and stop there are the ones who end up with an enforcement notice about a fence.

Why the change of use is not development

Section 55 of the Town and Country Planning Act 1990 excludes from development any change of use where the before and after uses fall within the same class. Since September 2020, offices, research and development, light industrial, shops, cafés, gyms, medical uses and creches and day nurseries have all sat inside the single Class E, so the move from an office at E(g)(i) to a nursery at E(f) is outside planning control.

Article 4 directions cannot touch it either. A direction withdraws permitted development rights granted by the General Permitted Development Order, and a change within a use class is not permitted development, it is simply not development. That is a real difference from a change to a use outside Class E, where an article 4 direction can and does bite.

The same logic applies across the class, which is why offices to laboratories under Class E flexibility works the same way.

What can still stop it

Three things, and they all sit in the property's own history rather than in national policy.

A condition on an earlier permission is the most common. Permissions granted before the 2020 changes are still construed by reference to the old classes, so a condition restricting the premises to office use, or to use within the former Class B1(a), continues to do exactly that. The nursery would breach it. Removing the condition takes a section 73 application, and our note on conditions restricting use class or occupier covers when those applications succeed.

A section 106 agreement can have the same effect, often in office to residential pressure areas where the council secured employment floorspace.

And the lease may prohibit it regardless of planning. That is a landlord and tenant question, but it kills as many schemes as planning does.

Check all three before signing anything. Where the position is arguable, a lawful development certificate for a proposed use under section 192 of the 1990 Act settles it, and the fee is modest compared with the cost of finding out later.

What the council can still control

Physical works are development even where the use change is not.

The list that matters for a nursery conversion: extensions and canopies, new or altered openings where they materially affect the external appearance, boundary treatments above the permitted heights, hardstanding and parking layouts on some sites, external play equipment of any scale, and signage, which runs under the advertisement regulations rather than the planning application system.

Access is the one to resolve first. A new or widened vehicle crossover requires the highway authority's consent under the Highways Act 1980 and usually planning permission as well, and a nursery with no safe drop-off arrangement will attract objections whether or not the use needs permission.

Outdoor play space and early years standards

Planning and childcare regulation ask different questions here, and both have to be answered.

The early years statutory framework sets indoor space requirements per child by age band and requires access to outdoor play, or daily outdoor activities where a suitable outdoor area is not available on site. Those figures drive the registered capacity, which drives the business case, so they come before the planning analysis rather than after it.

Planning then asks whether the outdoor space works in its context. A roof terrace over a residential neighbour, a yard against a party boundary, or a play area beneath first floor flat windows all raise amenity questions that a first floor office never did. Acoustic fencing, a limit on the number of children outside at one time, staggered outdoor sessions and a buffer planting strip are the mitigations that usually appear, and they are worth designing in rather than offering under pressure.

Where the outdoor area is shared with parking or servicing, expect the council to want it physically separated rather than marked out.

Drop off, parking and highway safety

A nursery generates short, sharp peaks: a concentrated arrival period in the morning and a longer departure spread in the late afternoon, with a high proportion of car trips even in accessible locations.

Where physical works or a planning application are involved, a Transport Statement covering the drop-off arrangement, the parking provision, the staff trips and the pedestrian routes to the entrance answers most highway objections. Where no application is needed, the same analysis is still worth doing, because the alternative is a complaint to the council within the first fortnight of opening.

Practical measures that work: a staggered session start, a defined drop-off bay with a one way circulation where the site allows, staff parking separated from parent parking, and a written arrangement with a nearby car park where the site cannot accommodate the peak. Put the arrangement in the operational statement so that it is on the file.

Noise and neighbouring amenity

Children playing outdoors is the objection that arrives, and it is a legitimate one at close range even though it attracts little sympathy in the abstract.

The planning question is whether the noise would cause material harm to residential amenity, judged in context. The separate regime is statutory nuisance under the Environmental Protection Act 1990, which the environmental health team can pursue regardless of the planning position. Mechanical plant is the other source and is often the more measurable one: kitchen extract, air conditioning condensers and ventilation units all have to be assessed against the background sound level.

Where the site is close to housing, a Noise Impact Assessment covering both plant and outdoor play, prepared by a suitably qualified acoustician, is the document that resolves the argument. Councils usually expect a qualified author for this work and professional review is strongly advised.

Registration, building regulations and the works

Three separate consent regimes run alongside planning, and none of them is satisfied by the use class analysis.

1. Registration with the childcare regulator, which assesses premises, staffing and safeguarding, and which has its own lead time.
2. Building regulations approval for the material change of use, covering fire safety, means of escape, ventilation, accessibility and sanitary provision, which on an office conversion usually means more than people expect.
3. Planning permission for any physical works that amount to development, plus advertisement consent for signage and highway consent for access works.

Sequence them so that the building regulations design is settled before the registration inspection, because a fire strategy change can move the layout and the layout drives the registered numbers.

Where any element does need permission, a short Planning Statement tying the operational arrangements to the physical proposals gives the officer a single document to work from, rather than a set of drawings and a hopeful covering email.
