Getting permission for a wedding venue in a farm barn

Running weddings in a farm barn is a change of use to an events venue, and an events venue does not sit in any class of the Use Classes Order. It is sui generis, which means full planning permission every time, with no permitted development route and no ability to slide into it from an agricultural or storage use.

The 28 day temporary use right under Schedule 2 Part 4 of the General Permitted Development Order does not rescue you either. That right applies to the use of land and moveable structures, not to the use of a building, so a marquee in a field for a limited number of days each year is a different proposition from a converted barn with a bar and a dance floor. The day count has also been amended more than once, so check the current wording of the Order before relying on it.

Where the change of use line falls

A single family wedding on your own farm is not a change of use. A business holding forty events a year, advertised, with staff, catering and a licence, plainly is. Between those two points the question is one of fact and degree, and the tests an officer applies are frequency, permanence, the physical alterations made, whether the agricultural use continues, and whether the character of the site has changed.

The practical trigger is usually advertising. Once the barn appears on a wedding listing with a price, the council has evidence of a commercial use and the fact and degree argument becomes very hard to run.

Where the barn is used for events alongside genuine continuing farming, a mixed use can be applied for, which is often the better description because it protects the agricultural rights. Say so in the application rather than describing the site as purely a venue.

Amplified music, curfews and the conditions you will get

Noise is what decides most rural venue applications. The two sources are different and need separating in the evidence: music inside the building, and people outside it.

Music breaking out through a barn door or a roof light is straightforward to control by design, with a lobbied entrance, an acoustically rated roller shutter, upgraded roof lining and a noise limiter set and sealed at a level agreed with environmental health. Guests standing outside at half past eleven are not controllable by design at all, which is why the conditions councils impose focus on curfews, a management plan, and a requirement that doors and windows are kept closed during amplified music.

Expect conditions along these lines:

• a cut-off time for amplified music, commonly earlier than the licensing hours
• a separate, later time by which the site must be cleared of guests
• a fixed limit for music noise measured at the nearest noise sensitive property
• a limit on the number of events per calendar year
• a requirement that the noise limiter is calibrated and its settings recorded

A Noise Impact Assessment should measure the existing background level at the nearest dwellings across the evening and night periods, not a single daytime sample, and should assess plant using BS 4142:2014+A1:2019 separately from the music. Where the background falls very low after midnight, as it does in open countryside, a level that would pass in a town will not pass here.

Guests, taxis and the lane

Rural venues generate a traffic pattern no highway officer sees anywhere else. Arrivals cluster into a thirty minute window, almost every guest arrives by car or minibus, and the departure is a stream of taxis late at night on unlit single track roads.

Deal with it directly. A Transport Statement should cover visibility splays at the access measured against the actual recorded speeds rather than the speed limit, the width of the approach lane and whether two cars can pass, the number of passing places and their condition, on-site parking laid out to a plan with a surface that works in February, and a marshalled arrival and departure arrangement written into the management plan.

Parking on grass is fine in July and unusable in January. If the business will run year round, show a reinforced grass or permeable surface with a drainage design, because the fallback of parking on the verge is what generates objections from every other lane user.

Also plan for coaches and for the wedding car turning circle. An access that works for a tractor does not necessarily work for a stretched limousine.

Foul drainage at peak occupancy

This is the item most applications underestimate. A barn that served twelve cattle now needs to handle 150 people concentrated into six hours, with a catering kitchen attached.

Existing septic tanks are almost never adequate. The likely answer is a package treatment plant sized on peak population equivalent, discharging either to a soakaway system or to a watercourse. In England, small sewage discharges can operate under the Environment Agency general binding rules only within volume limits, currently 2 cubic metres a day to ground and 5 cubic metres a day to surface water, and above those a permit is required. Kitchen waste needs a grease trap.

A Foul Sewage Assessment setting out the population equivalent, the treatment specification, percolation test results and the discharge route answers the drainage consultation before it becomes a reason for refusal. Get the percolation testing done before you design, because a failed test changes the whole scheme.

Reusing the building without spoiling it

National policy supports sustainable rural tourism and the reuse of redundant or disused buildings where the development enhances the immediate setting. That support is conditional on the design, and traditional agricultural buildings lose their character quickly under new openings, rooflights and render.

If the barn is listed, listed building consent is needed alongside planning permission, and the internal alterations, services and toilets will be the difficult part. If it is unlisted but traditional and within a conservation area or contributing to the setting of a listed farmhouse, a Heritage Statement assessing significance and the effect of the proposals is required and should be written before the design is fixed rather than after.

External lighting is the other thing that damages a rural setting and generates complaints. Car park and path lighting on a dark lane is highly visible for a long distance, and a Lighting Assessment applying the Institution of Lighting Professionals guidance on obtrusive light, with the site placed in the correct environmental zone, gives the officer something to condition rather than a reason to worry.

The application pack

For a typical barn venue in open countryside the submission runs to a planning statement dealing with the rural policy case and the fact and degree of the change of use, the noise assessment, the transport statement, the foul drainage assessment, a heritage statement where relevant, a lighting scheme, an ecology appraisal covering bats and barn owls in the roof, and a written events management plan.

The management plan carries more weight than most applicants realise. Event numbers, hours, staffing, marshalling, taxi arrangements, a complaints procedure and a named responsible person can all be secured by condition, and offering them at the outset is the difference between conditions you can live with and conditions imposed on you.

Start with the noise survey and the percolation test. Both take time, both can kill a scheme, and both are cheaper to discover early.

This is general guidance rather than legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
