Veterinary and dental practices: which use class and why

A dental surgery is Class E(e), medical or health services, and moving into a vacant shop or office within Class E needs no planning permission at all. A veterinary surgery is the harder question, because the Use Classes Order says nothing about animals, and authorities split on whether a vets' practice sits in Class E(e) or outside the classes altogether. Boarding, kennels, catteries and dog day care are clearer: they are not in any class, so they are sui generis and need express permission every time.

Get the classification settled before you sign a lease. The difference between a permitted change within Class E and a sui generis application is several months and a refusal risk.

Dental practices and Class E(e)

Class E(e) of the Town and Country Planning (Use Classes) Order 1987, as amended in 2020, covers the provision of medical or health services other than from premises attached to the practitioner's own residence. A dental practice, a GP surgery, a physiotherapy clinic, a chiropodist and an audiology clinic all fall within it.

Because changes of use within the same class are not development, a dentist taking a former shop, bank branch or office in Class E does not need planning permission for the change. That is the single most useful consequence of the 2020 amendment for health occupiers.

Three caveats. The exception for premises attached to the practitioner's residence means a surgery in a house extension is not Class E(e) and needs permission. Physical works, signage and plant are separate consents whatever the use class position. And an Article 4 direction can remove permitted changes in a defined area, so check whether one covers the premises.

Where the practice involves general anaesthesia, overnight recovery or significant medical gas storage, the operational detail starts to matter to the authority even where the class does not change, and a short planning statement setting out hours, staff numbers and patient movements is worth submitting with any associated works application.

Veterinary surgeries and the usual classification

The Order does not define medical or health services, and it does not mention veterinary use. Before 2020 the equivalent wording sat in Class D1, and the long-standing reading was that it referred to services for people. On that reading a veterinary surgery is sui generis.

Many authorities now take the opposite view and treat a small animal practice as Class E(e) in substance, on the basis that the activity, the staffing and the external effects closely resemble a human clinic. Others hold the traditional line. This is a point on which practice varies between neighbouring councils, and I would not advise a client to rely on either reading without confirming it.

Two ways to resolve it. A pre-application enquiry gives you the authority's written view quickly at modest cost, though it is advice rather than a determination. A certificate of lawfulness of proposed use or development under section 192 of the Town and Country Planning Act 1990 gives you a formal decision on whether the proposed use would be lawful, and that is the only route that binds the authority.

Where the practice is mixed, the classification follows the primary use with ancillary elements absorbed into it. A consulting practice with a small retail display of pet food is still a veterinary use. A pet shop with a vet attending two mornings a week is a shop.

Boarding, kennels and sui generis uses

Once animals stay overnight, or are kept in numbers for day care, the use moves outside the classes.

Boarding kennels, catteries, dog day care, breeding establishments, grooming parlours with boarding, and animal crematoria are all sui generis. So, in most readings, is a veterinary hospital with inpatient facilities, because the overnight element changes the character of the use regardless of where the surgery itself sits. A full planning application is required, and because sui generis uses have no permitted changes, any later alteration of the use also needs permission.

That cuts both ways and is worth knowing: a sui generis consent is specific, so a permission for a cattery does not authorise a dog day care, and an authority can and will enforce the difference.

Licensing runs alongside. Animal boarding, dog breeding and day care require a licence from the local authority under the animal welfare licensing regime, with its own standards for space, staffing ratios and record keeping. A planning permission does not deliver a licence, and licence conditions on animal numbers may be tighter than anything in the planning consent.

Noise, odour and waste evidence

Noise is what refuses these applications, and for kennels and day care it is barking rather than plant.

Plant noise is assessed conventionally against BS 4142:2014+A1:2019, comparing the rating level of the specific sound against the background sound level at the nearest noise-sensitive receptor. Barking does not fit that method well, because it is intermittent, tonal and highly noticeable. The honest approach is a scheme designed to control it: internal kennelling with acoustic treatment, no external runs close to residential boundaries, limited outdoor exercise hours, and a management regime with a named responsible person. Then present the acoustic assessment of the plant and the management plan as a package.

Odour and waste need their own answers. Veterinary clinical waste is controlled waste and in part hazardous, so set out storage, segregation and the licensed carrier arrangement. For kennels, soiled bedding and waste volumes drive the bin store sizing. Where mechanical extraction serves treatment rooms, isolation areas or an animal crematorium, a ventilation and extraction statement covering duct routes, discharge height and abatement is the document the environmental health officer will read.

Animal crematoria are a separate regulatory world again, with environmental permitting and emission limits, and planning is only part of the consenting route.

Out of hours operation

A 24-hour emergency veterinary service generates vehicle movements and door slamming at 2am in a location that was quiet when the officer visited at eleven in the morning.

Say so in the application rather than letting it emerge in a condition negotiation. Set out the hours of each activity separately: consulting hours, out-of-hours emergency cover, deliveries, waste collection, and staff arrivals. Where night working is proposed, offer a management approach: a side entrance away from dwellings, a lighting scheme controlled to avoid spill, and a restriction on external animal exercise at night.

Where the authority imposes hours you cannot work with, varying the condition later is a section 73 application with its own evidence burden, as our note on changing the hours a use operates explains. It is far easier to get the hours right first time.

Parking and access

Health and veterinary uses generate short-stay trips with high turnover, and the arrival pattern is clustered around appointment slots.

Local parking standards usually express a requirement per consulting room or per 100 m2 for medical uses. Where a vets' practice is treated as sui generis, no standard applies directly and the authority will reason by analogy, which is an argument you can shape with evidence. A short transport statement with observed or comparable trip rates, the appointment schedule, staff parking, and a servicing arrangement for deliveries and waste collection usually settles it.

Do not forget the practical detail of animal handling. A dropped kerb, a loading area where an anxious dog can be unloaded away from traffic, and a separate route for animals arriving in distress are the things an officer notices on a site visit.

Conditions on animal numbers

Expect numerical conditions, and read them before the decision issues.

Typical forms limit the maximum number of animals boarded at any one time, restrict the number of outdoor exercise areas in use simultaneously, tie the use to the approved layout, require a noise management plan to be implemented and maintained, and control hours of operation and of external exercise. Some authorities restrict the use personally or to a named operator, which affects the saleability of the business.

A condition limiting numbers to a figure below the licensing authority's own capacity assessment is a practical problem, so check the two against each other before you accept them. Where a condition is imprecise, ask for it to be reworded at the draft stage.
