Is a car park a use class? Parking under the 1987 Order

There is no car park use class. The Town and Country Planning (Use Classes) Order 1987, as amended in September 2020, runs through Classes B2, B8, C1 to C4, E, F1 and F2, and parking appears in none of them. A car park operated as a use in its own right therefore sits outside the classes altogether, as sui generis development. Parking that simply serves a shop, office or workshop is treated differently, and that distinction usually decides whether you need permission at all.

Parking with no class of its own

Sui generis is not itself a class. It is the label planners use for a use Parliament left out of the Order, and the practical consequence is blunt. Nothing in Article 3 of the Order lets you move in or out of it without an application.

A commercial pay-and-display car park cannot become a retail unit under Class E flexibility. A Class E unit cannot become a commercial car park without permission. Coach parks, lorry parks and vehicle storage compounds sit in the same position, though where vehicles are stored rather than parked in daily rotation a council may argue the use is Class B8 storage instead, which changes the argument entirely.

One trap follows from all this. Because there is no class, there is no "change within a class" route available to you. Every material change involving a standalone car park is an application.

Ancillary parking and where the line falls

Parking incidental to the main activity on a site forms part of that use. Staff bays behind an office, customer spaces in front of a shop, hardstanding beside a workshop: none of these is a separate planning unit and none needs its own permission.

The line moves when the parking starts serving people who have no business with the primary use. A supermarket that opens its car park to commuters on weekday mornings, for a charge, has probably introduced a second use. Whether the change is material turns on scale, duration and effect on the highway, which is the question section 55 of the Town and Country Planning Act 1990 asks.

Two tests settle most arguments. Is the parking still subordinate in scale to the primary use? And is it still functionally tied to it? If either answer is no, you are looking at a mixed use, and the application form should say so. Getting that wording right matters, and our note on describing a mixed use correctly sets out how officers read the description.

Changing the use of land to parking

Laying out an open site for parking is a material change of use in most cases. Councils look at it closely because highway and drainage effects arrive with it.

Two permitted development routes are worth checking before you apply:

• Schedule 2 Part 4 Class B of the Town and Country Planning (General Permitted Development) (England) Order 2015 allows the temporary use of land for most purposes for up to 28 days in a calendar year, with a shorter limit for certain uses. That suits an overflow event car park. It does not support a permanent one.
• Schedule 2 Part 1 Class F allows a hard surface within the curtilage of a dwellinghouse, subject to the porous surfacing condition where the area between the house and the highway exceeds 5 m².

Neither helps a commercial operation on open land. For that you need a full application with a site layout, a swept-path drawing where service vehicles are involved, and a Transport Statement if the council's validation list asks for one. The Planning Statement carries the policy case: why this location, what the parking serves, and how the proposed development sits against the adopted local plan.

An illustrative example. A 20-space yard beside a parade of shops, used until now by the shop tenants, is let commercially to office workers from a business park half a mile away. The number of vehicles barely changes. The character of the use does, because the trips are no longer linked to the parade. Cases like that tend to reach an enforcement officer rather than a planning committee.

Surfacing, drainage and lighting

A large area of new impermeable surface brings its own consents and its own objections. Surface water has to go somewhere, and a council will usually expect permeable construction or an attenuation feature sized against the Defra non-statutory technical standards for sustainable drainage. On a site with fuel deliveries or vehicle washing, the sewerage undertaker will ask about an oil interceptor before it agrees a connection.

Lighting is the part applicants underestimate. Columns are structures, so they generally need permission in their own right unless they fall within a specific permitted development class, and the beam control matters more than the number of columns. The Institution of Lighting Professionals guidance on obtrusive light, GN01, sets the environmental zones and the vertical illuminance limits officers quote back at you. Keep columns away from residential boundaries, specify flat glass luminaires with sharp cut-off, and commit to a curfew if the site adjoins housing.

Air quality can also bite. Inside an Air Quality Management Area, a new public car park changes traffic distribution, and the environmental health team will want to see that accounted for.

Charging points inside an existing car park

Retrofitting charge points to an existing car park is usually permitted development rather than a fresh application. Schedule 2 Part 2 of the GPDO deals with it: Class D covers an electrical outlet mounted on a wall or building within an off-street parking area, and Class E covers a free-standing upstand serving one parking space, with a height limit and restrictions near a highway boundary. Both classes carry conservation area caveats, and both have been amended more than once, so read the current text rather than a summary.

Where the installation involves a substation, a new switchroom or a canopy, those are separate structures and the permitted development argument stops.

Conditions that restrict who may park

Councils often try to control who uses a car park by condition. A condition limiting bays to staff of a named business, or barring commuter parking, has to pass the six tests in the Planning Practice Guidance on the use of planning conditions: necessary, relevant to planning, relevant to the development, enforceable, precise and reasonable in all other respects.

Enforceability is where these conditions fail. A condition that requires the operator to police the identity of every driver is hard to monitor, and an inspector will say so on appeal. A condition tied to a measurable outcome works better: maximum bay numbers, hours of operation, a barrier controlled to set times, or a requirement that spaces be marked and allocated on a plan approved by the authority.

Personal conditions, which tie a permission to one named occupier, are exceptional and the guidance treats them that way.

Proving the lawful use of a yard

Long use can make an unauthorised car park lawful. For a change of use other than to a single dwellinghouse, continuous use for ten years without enforcement gives immunity, and a certificate of lawfulness of existing use or development under section 191 of the 1990 Act is the only way to put that beyond argument. The Levelling-up and Regeneration Act 2023 moved several of the shorter immunity periods to ten years, so check which period applies to your facts before you rely on the old four-year rule.

Evidence wins these applications. Dated aerial photographs, tenancy agreements, parking income records, utility bills for a barrier or ticket machine, and statutory declarations from people who used the site all help. Gaps of a year or more in the record are what refusals are built on.

A certificate of lawfulness of proposed use under section 192 is the mirror image, and it is the sensible route if you want certainty before spending money on surfacing.
