Car showrooms, vehicle repair and petrol filling stations

Motor trade premises sit in three different places in the planning system, and a single site often contains all three. Vehicle sales and hire are sui generis, outside every use class. Repair and servicing are usually general industrial. A petrol filling station is sui generis as well. None of them can move into or out of Class E without permission, which is why a car showroom use class question is rarely answered by pointing at the Use Classes Order.

For an occupier taking a lease, that matters more than it sounds, because a change that looks like a small operational adjustment can be a material change of use requiring an application.

Where vehicle sales sit in the use classes

The Use Classes Order expressly excludes the sale or display for sale of motor vehicles from the classes, along with hire of motor vehicles. Both are sui generis.

The practical effect is that no permitted change gets you into or out of a vehicle sales use. Moving from a retail shop to a car sales pitch needs permission. So does moving from a car showroom to an office, a gym or a shop, even though all three sit within Class E.

Display on open land is development in its own right where it amounts to a material change in the use of that land. A forecourt that has always had two cars on it and now has thirty is a change of character, and the question of whether more of the same needs consent is a recurring one, set out in intensification and when doing more of the same needs consent.

Repair and servicing as general industrial use

Vehicle repair, servicing and MOT testing are normally treated as general industrial, sitting in Class B2 rather than in any part of Class E.

That classification carries consequences. B2 premises adjoining housing attract conditions on hours, on where work may be carried out and on whether doors may be left open. Spray booths bring emissions, and depending on solvent throughput may need an environmental permit from the council's environmental health team as a separate regime from planning.

Where sales and repair occupy the same site, the planning unit question decides what is being assessed. A single unit with an ancillary workshop is one thing. Two operations with separate access, separate staff and separate customers may be two planning units, and the way councils approach that is covered in the planning unit and how councils decide what they assess.

Tyre and exhaust fitting, valeting and vehicle wash operations tend to be assessed on their own facts. Noise is usually the deciding issue for the first, and water discharge and lighting for the others.

Petrol filling stations outside the classes

A petrol filling station is sui generis, and it carries a licensing regime alongside planning. Storage and dispensing of petroleum are regulated by the petroleum enforcement authority, and the site also falls within the regime governing dangerous substances and explosive atmospheres.

Those regimes are separate from planning permission and neither one substitutes for the other. A planning permission does not authorise the storage of petroleum, and a petroleum licence does not authorise a change of use.

Planning issues for a filling station cluster around access and turning, tanker delivery movements and their timing, lighting spill onto neighbouring properties, noise from the forecourt at night and from air and vacuum equipment, and the contamination legacy of the tanks. A site with a long fuel history will need a phase 1 desk study at minimum before any redevelopment, and often intrusive investigation.

Forecourt shops and the retail element

The shop on a filling station forecourt is the part that generates most disputes, because it has grown from a kiosk selling oil into a convenience store.

Where the retail element remains ancillary to fuel sales, it forms part of the sui generis use. Where it has become a destination in its own right, with customers arriving on foot or parking specifically to shop, it may be a separate retail use requiring permission. The usual indicators are floorspace, the range of goods, opening hours that extend beyond fuel trading, separate signage and dedicated parking.

Councils often deal with this by condition, restricting the net sales area of the shop to a stated figure and tying it to the fuel use. Read those conditions before acquiring a site, because a condition limiting the shop to 100 square metres is a value point rather than a technicality.

Drive-through elements raise a related set of classification and highway questions, addressed in drive-through units, classification and highway evidence.

Mixed operations on one site

Many sites run sales, repair, valeting, fuel and a shop together. Describe the operation accurately on the application rather than choosing the label that seems easiest.

An inaccurate description causes two problems. It can produce a permission that does not authorise what you actually do, leaving part of the operation unlawful. And it can restrict future flexibility, because a permission for a sui generis mixed use will usually be conditioned to that mix.

Set out the floorspace or land area given to each element, the staff numbers, the hours for each activity and the vehicle movements each generates. If a part of the operation is intended to expand, say so at the application stage rather than seeking to argue later that it was always included.

Noise, fumes and hours in a residential setting

Where housing adjoins, the environmental health officer will shape the permission more than the case officer does.

Expect requests covering reversing alarms and their type, the use of impact tools and air lines, whether repair work may be carried out in the open, extraction from spray booths and its discharge point, delivery and collection hours including transporter deliveries which usually arrive early, and lighting levels at the boundary.

Vehicle transporter deliveries are the most common source of complaint at sales premises, because a transporter unloading at six in the morning on a residential street is audible over a wide area. Deal with it in the application by proposing a delivery management arrangement with stated hours and an off-street unloading position.

Extraction and odour from spray finishing needs its own treatment, and the discharge design normally sits in a ventilation and extraction statement rather than being left to a condition.

Electric vehicle charging and what it changes

Charging infrastructure alters the classification questions in a few ways worth knowing.

Permitted development rights allow electric vehicle charging points in off-street parking areas within certain limits, including height limits and restrictions in conservation areas and on listed buildings. Those rights cover the charging equipment itself rather than any change of use of the land.

A charging hub as a standalone commercial operation, without fuel and without retail, does not fit neatly anywhere in the Use Classes Order, and authorities have approached it in different ways. Describe it precisely and expect the classification to be argued.

Two practical consequences for an existing site. Rapid charging equipment brings substantial electrical infrastructure, which means a substation or cabinet requiring its own consent and a connection agreement with the distribution network operator, both of which take longer than the planning application. And charging bays change dwell times, which changes the traffic profile enough that a transport statement may be required where the previous use needed none.

Contamination is the other one. Converting a former filling station to charging or to any other use runs into the tank legacy, and remediation cost is the item that most often stops those schemes.
