Opticians, pharmacies and the Class E health boundary

A pharmacy and an opticians both sit inside Class E, but in different limbs of it, and that is what decides whether you need planning permission to move in. Retail sale of goods falls in Class E(a). Provision of medical or health services falls in Class E(e). Because both are limbs of the same class, a change from one to the other is not development at all under section 55(2)(f) of the Town and Country Planning Act 1990, so no application is needed for the use itself. The traps are elsewhere: old conditions, Article 4 directions, physical works and the point at which a shop stops being a shop in planning terms.

Where each business sits in Class E

The Town and Country Planning (Use Classes) Order 1987, as amended in September 2020, groups most high street uses into a single Class E. The limbs that matter here are E(a), display or retail sale of goods other than hot food, and E(e), provision of medical or health services other than at premises attached to the residence of the consultant or practitioner.

A community pharmacy selling over-the-counter medicines, toiletries and baby goods is retail under E(a). The dispensary at the back is part of the same operation and does not change that. An opticians selling frames and lenses is also E(a), and the sight testing room is E(e) activity carried on within the same planning unit.

Both businesses are therefore mixed in fact and single in law. The council assesses the planning unit as a whole and asks what its primary use is.

Why moving between the limbs is not development

Section 55(2)(f) says that a change of use within the same use class is not development. Class E was drawn deliberately wide in 2020 so that a unit could move between shop, cafe, gym, office, nursery and clinic uses without an application.

So a vacant clothes shop can become a pharmacy, and a pharmacy can become an audiology clinic, with no planning application for the change of use. The council cannot refuse it, cannot impose conditions on it, and cannot require a transport statement for it.

That is a genuine freedom and it is worth using. But it is narrower than the estate agent's summary usually suggests.

The conditions that still bite

Class E flexibility applies to the use class, not to the planning history of the unit. Where a permission granted before September 2020 carries a condition restricting the premises to a use within the old Class A1 and for no other purpose, that condition survives the reclassification. Moving to a clinic use would breach it, whatever the Use Classes Order now says.

These conditions are common on units in retail parades, on ground floors of residential blocks, and on anything consented as part of a wider scheme where the council wanted to control the mix. Pull the planning history from the council's public register before signing a lease, and read every condition on every permission affecting the unit.

Article 4 directions are the second check. A number of authorities have made directions removing the Class MA right to convert Class E premises to dwellings, and some have directions affecting particular frontages. A direction does not stop a pharmacy opening in a shop, but it changes the exit options and therefore the value of the lease.

Where a unit is sui generis rather than Class E, none of this applies. A former hot food takeaway, a betting shop or a funeral directors is outside Class E, and moving into it needs permission. The classification question for that last one is less obvious than it looks, as our note on funeral directors and use class explains.

Consulting rooms and the point the use changes

Adding consulting rooms to a pharmacy does not take it outside Class E, because E(e) is inside the class. The question that does arise is whether the planning unit has changed character so much that a material change of use has occurred outside the class altogether.

That is rare for pharmacies and opticians, and it usually comes up in one of two ways. The first is where consulting rooms are let to independent practitioners operating as separate businesses, so a second planning unit is created within the shop. The second is where the service offered stops being a health service in any ordinary sense, which is where cosmetic treatments sit, a boundary we look at in the piece on beauty salons and extraction.

Officers reach for the planning unit test in both cases. If the occupation is separate, the rates are separate and the access is separate, expect an argument.

Parking, deliveries and short stays

Councils cannot control parking on a Class E to Class E move, which is precisely why they scrutinise everything that does come before them. Where a change needs permission anyway, because a condition or an Article 4 direction is engaged, the highway authority will look at short-stay demand.

Pharmacies generate high-frequency, short-duration trips. Prescription collection peaks in the hour after surgeries close, and that is when the loading bay outside a parade is already full. An optician generates fewer trips but longer stays, because appointments run 30 minutes or more.

A transport statement covering existing kerbside provision, likely trip patterns and delivery arrangements answers most of what a highway officer asks. Keep it proportionate. A single unit on an existing parade does not need a full transport assessment, and submitting one invites questions you did not have to answer.

Waste, storage and what planning does not control

Controlled drugs storage is regulated under medicines and misuse of drugs legislation and by the pharmacy regulator, not through the planning system. The council will not condition a safe. What it will ask about is where the bins go, how clinical waste is stored before collection, and whether the collection vehicle can reach it without blocking the footway.

Show a bin store on the plan with dimensions, and state the collection frequency and the contractor's vehicle type. That single drawing removes most environmental health objections before they are raised.

Refrigeration plant for vaccines is the other item worth flagging. External condensers on a residential frontage can generate a noise objection, and where that is likely, a short noise impact assessment to BS 4142 costs less than an enforcement complaint six months in.

Shopfronts, signs and works that do need consent

The use may be free. The works usually are not.

1. Alterations to a shopfront that materially affect the external appearance need planning permission, and in a conservation area the threshold for what counts is lower.
2. Listed building consent is needed for works to a listed shopfront, inside and out, regardless of whether planning permission is also required.
3. Advertisements are controlled separately under the 2007 advertisement regulations. Many fascia signs on business premises have deemed consent, but illuminated signs, projecting signs and signs in conservation areas or on listed buildings often need express consent.
4. New extraction or air handling equipment on an elevation is development and normally needs permission.
5. Level access works to a threshold may need permission where they project into the highway, and will need the highway authority's agreement in any case.

An illustrative example on a suburban parade

Take an illustrative case. A vacant card shop on a 1930s parade is taken by a pharmacy. The unit was consented in 1998 with a condition limiting it to Class A1 retail and for no other purpose.

Retail sale of medicines and toiletries is A1 in substance, so the condition is not breached by the core use. Adding two consulting rooms for NHS services, letting one of them to a visiting podiatrist, and installing an external condenser changes the picture. The condenser needs permission. The let room raises a planning unit question. And the condition, drafted in the language of the old order, is the hook the council will use if it wants to look at the whole thing.

The safe route is a short pre-application enquiry setting out the proposed mix, followed by an application for the external works alone if the council agrees the use is within the condition.

Before signing, check the planning history, the conditions and any Article 4 direction. If an application turns out to be needed, see which reports your site is likely to need by entering the postcode.
