A barn used as a wedding venue and the 28-day limit
The 28-day rule applies to land, not to barns. That single point decides whether a wedding barn is lawful or waiting for an enforcement notice.
Barn wedding venue planning permission is needed from the first paid event held inside the building, and the reason catches a great many owners out. The temporary use right in Class B of Part 4 of Schedule 2 to the General Permitted Development Order 2015 permits the use of any land for any purpose for not more than 28 days in a calendar year. It applies to land. It does not authorise the temporary use of a building, so a barn hosting events is outside it from day one.
Marquees are a different matter, because a marquee on a field is a moveable structure on land. That is why so many rural event businesses started under canvas and ran into difficulty the year they moved indoors.
Agricultural use against an events use
An agricultural barn is in agricultural use, and holding weddings in it is a material change of use under section 55 of the Town and Country Planning Act 1990. The change is from agriculture to a leisure or events use, usually treated as sui generis because nothing in the Use Classes Order fits a venue hiring itself out for private functions.
Mixed use is the honest description for most holdings. The barn is used for events on perhaps 30 to 60 days a year and for storage the rest of the time, and the permission that works is one for a mixed agricultural and events use with a cap on event numbers. Applying for a wholesale change to a venue when the barn is still needed for the farm produces a permission that does not match the operation.
Where the barn is a traditional building rather than a modern portal frame, the conversion works themselves need permission too, and any listing or curtilage listing brings listed building consent into play. The broader picture for rural event buildings is set out in the guide to wedding and events venues in rural buildings.
The limits of temporary use rights
Class B of Part 4 is narrower than its reputation. The limits worth knowing:
- It permits the use of land, not of buildings, so the barn itself is not covered.
- The allowance is 28 days in total in a calendar year, counted across all temporary uses of that land.
- Within those 28 days, no more than 14 may be used for markets or for motor car and motorcycle racing.
- It permits the provision on the land of moveable structures for the purposes of the permitted use, which is how a marquee and temporary toilets are covered.
- The right does not apply on land within the curtilage of a building in some circumstances, and it is excluded on certain designated land, so check the current text of the Order before relying on it.
But counting is where enforcement cases are won and lost. A day on which the marquee is erected and a day on which it is taken down are days of use, and so is a day used for setting up. Keep a dated log with photographs, because the burden of showing that the use falls within the right sits with the person relying on it.
A lawful development certificate under section 191 or 192 of the 1990 Act is the only formal way to confirm that a use is lawful. If the business is being financed or sold, get one.
Access, visibility and coach movements
The highway case on a single track lane is usually the hardest part of the application, and it is answered with survey evidence rather than with a statement that guests will drive carefully.
| Issue | Evidence that answers it |
|---|---|
| Visibility at the access | Speed survey and splays designed to measured speeds |
| Lane width and passing | A plan of passing places, with distances between them |
| Coach and minibus access | Swept path drawings for the largest vehicle expected |
| Arrival and departure peaks | A timing profile, because guests arrive together and leave together |
| Taxi and private hire waiting | A designated waiting area off the carriageway |
Encouraging coaches rather than cars reduces movements and is worth proposing, but a 12 m coach on a 3 m lane with no passing places is a worse outcome than 40 cars. Model it before you offer it. A short Transport Statement covering the access, the parking layout and the departure profile is normally what the highway authority needs.
Noise, amplified music and dispersal
Open countryside is quiet, which makes it the most difficult setting for an events use. Background sound levels at night on a rural lane can be very low, so music that would be inaudible in a town is clearly audible at a neighbouring farmhouse several hundred metres away.
The standard for industrial sound is not the right tool for amplified music, and assessments normally follow the recognised guidance on noise from pubs and clubs, setting a music noise level at the nearest noise-sensitive facade or specifying that music should be inaudible there after a given hour. What a defensible Noise Impact Assessment contains is a baseline survey covering late evening and night, an assessment of music breakout through the barn envelope with doors closed and with doors open, the effect of a lobby or acoustic doors, and an assessment of guest noise outside the building.
Dispersal is the part applicants forget. Fifty people on gravel at midnight, car doors, engines and headlights sweeping across a bedroom window generate more complaints than the band did. Deal with it with a dispersal plan, a lit but low-level pedestrian route, a marshalled departure and a carriage time written into the conditions.
A premises licence under the Licensing Act 2003 is a separate consent from the local authority's licensing function, with its own hearing and its own conditions. The two sets of conditions should be consistent, and it is worth drafting the planning conditions with the licensing application in mind.
Parking on grass, drainage and water
Grass parking works until a wet October. The application needs a surfaced overflow or a reinforced grass construction, a defined route to it, and a statement about reinstatement if the field returns to agriculture. Permeable reinforced grass is usually acceptable to the authority and avoids an argument about new hardstanding in the countryside.
Foul drainage is the quiet constraint. A barn with no services needs a treatment solution sized for peak occupancy, not for average use, and 120 guests on a Saturday is a very different load from a farm office. The discharge is regulated by the Environment Agency, either under the general binding rules for small sewage discharges or under a permit where the thresholds are exceeded, and a Foul Sewage Assessment is where the calculation belongs. Water supply needs confirming with the undertaker or, on a private supply, a yield and quality assessment.
Conditions on numbers, hours and lighting
The conditions to expect, and to offer first:
- A maximum number of events in any calendar year, and sometimes a maximum in any week.
- A maximum number of guests at any one event.
- A terminal hour for amplified music, commonly 23:00, and a carriage time for departures.
- No amplified music outside the building.
- External doors and windows to be kept closed during amplified music except for access.
- A lighting scheme with a curfew, designed to the environmental zone for a dark rural area.
- Submission and implementation of a noise management and dispersal plan.
Propose the event cap and the terminal hour yourself. An operator who offers 40 events with music ending at 23:00 tends to get it. One who leaves the figures to the officer tends to get 20 and 22:30, and changing them later needs a section 73 application and fresh noise evidence.
This is general guidance, not legal advice. Permitted development rights, licensing requirements and local policy change, so check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
Does the 28-day rule allow weddings in a barn?
No. Class B of Part 4 of Schedule 2 to the General Permitted Development Order 2015 permits the temporary use of land, not of buildings, so events held inside a barn fall outside it. A marquee on a field is covered because it is a moveable structure on land, which is why many rural event businesses began under canvas.
How are the 28 days counted?
As total days of use of the land in a calendar year, across all temporary uses, with no more than 14 of them available for markets or motor racing. Days spent setting up and dismantling count as days of use. Keep a dated log with photographs, because the burden of showing a use falls within the right rests on the person relying on it.
What use class is a wedding venue?
Normally none, so the use is sui generis and permission is always needed. For a working farm the better application is for a mixed agricultural and events use with a cap on event numbers, because that matches how the barn is actually used. Applying for a wholesale change to a venue produces a permission that does not fit the operation.
How is music noise from a barn venue assessed?
Not by the industrial sound standard. Assessments normally follow the recognised guidance on noise from pubs and clubs, setting a music noise level at the nearest noise-sensitive facade or requiring music to be inaudible there after a stated hour. The assessment should cover breakout with doors open and closed, and guest noise outside the building.
Do I need a premises licence as well as planning permission?
Yes, if alcohol is sold, regulated entertainment is provided or late night refreshment is served. A premises licence under the Licensing Act 2003 is a separate consent with its own hearing and conditions. Draft the planning application with the licensing application in mind so the two sets of conditions, particularly on hours, do not conflict.
