Planning permission for a micro-brewery with a taproom

A microbrewery with a taproom almost always needs planning permission, because the brewing floor and the drinking area sit in different parts of the Use Classes Order and the combination usually falls outside any single class. Brewing is an industrial process. A taproom where people buy a pint and stay to drink it is a drinking establishment, which has been sui generis since September 2020. Put the two together on one site and the council will treat the whole thing as a mixed use requiring a full application, even if the unit you are taking already had industrial consent.

That is the short answer. The longer answer is that the decision will turn less on the use class argument and more on odour, noise and how beer and people move in and out of the building.

Use class for brewing and for the taproom

The Town and Country Planning (Use Classes) Order 1987, as amended in September 2020, puts general industrial processes in Class B2. Light industry sits in Class E(g)(iii), defined as an industrial process that can be carried out in any residential area without detriment to the amenity of that area. A small nano-brewery running a 400 litre kit on an industrial estate is often argued as E(g)(iii). A ten-barrel plant with a steam boiler, a grain silo and daily HGV deliveries is B2 territory.

Where you land matters for two reasons. Class E is flexible, so a unit already in E can move between E sub-uses without permission, which occasionally lets a small brewing operation start without an application. Class B2 is not flexible in that direction.

The taproom is the harder half. Public houses, wine bars and other drinking establishments were removed from the old Class A4 in 2020 and are now sui generis, meaning any change of use to or from them needs express permission. A brewery shop selling cans to take away is closer to retail. The moment you put out stools and start pouring, you are in drinking establishment territory.

Where a mixed use becomes sui generis

Planning law looks at the primary use and asks whether other activities are properly ancillary to it. A brewery with a small tasting counter open on Saturday afternoons, serving beer made on site, can be argued as ancillary to the brewing use. A taproom open five evenings a week, with a larger floor area than the brewhouse and its own trade, is a separate use in its own right.

Councils tend to test this on three things: floorspace split, opening hours, and whether the drinking side would survive if brewing stopped. Be honest about all three in your application. An enforcement case two years in, triggered by a neighbour complaint, is a far worse outcome than a condition limiting taproom hours from the start.

If the mix is real, describe the development as a mixed use of brewing and drinking establishment and apply for that. A Planning Statement is the place to set out the split, the hours and the management arrangements, with the floor areas for each part given in m².

Odour, extraction and boiling vents

Brewing smells. The wort boil is the main source, and it runs for an hour or more per brew, venting steam that carries a strong malt odour. Grain handling, spent grain storage and yeast add to it. On an isolated industrial estate this rarely troubles anyone. Within 50 metres of housing it is the single most likely reason for objection.

Environmental health officers will want to know the stack height, the discharge velocity, whether the vent terminates above the eaves of the nearest sensitive receptor, and what happens to spent grain between brew day and collection. A Ventilation and Extraction Statement covering the boil vent, any kitchen extract in the taproom, and the cellar cooling, is usually expected. Where housing is close, expect a request for an Odour Assessment following the Institute of Air Quality Management approach, which grades risk by source, pathway and receptor rather than by a single numeric limit.

Spent grain is worth a sentence of its own in the application. Stored in an open skip in July, it will generate complaints. Stored in a sealed IBC collected twice a week by a farmer, it will not.

Trade effluent and drainage

This is the consent most brewers forget. Discharging brewery washings to the public sewer is a trade effluent discharge, and section 118 of the Water Industry Act 1991 requires the written consent of the sewerage undertaker before you start. The undertaker sets limits on volume, pH, temperature, suspended solids and chemical oxygen demand, and charges for the discharge under its trade effluent tariff.

Brewery effluent is strong. Yeast, trub and caustic cleaning chemicals push chemical oxygen demand well above domestic sewage, and pH swings hard during a clean-in-place cycle. Most small breweries need at least a balancing tank and pH correction. That equipment takes floor area and needs a plant location on the drawings, so it is better identified before the layout is fixed than after.

Trade effluent consent runs separately from planning permission. Neither one substitutes for the other, and a planning officer will not check that you have applied for it.

Noise, hours and outdoor drinking

Two noise sources matter and they behave differently. Fixed plant, meaning glycol chillers, compressors, extract fans and cellar cooling, is assessed against BS 4142:2014+A1:2019, which compares the rating level of the specific sound against the background sound level at the nearest noise-sensitive receptor. Plant noise is predictable and can be designed out with attenuators, enclosures and sensible siting.

Patron noise is different. People talking outside with a drink at 10pm do not fit the BS 4142 method well, and councils handle it through conditions instead: closing the outdoor area at a fixed time, capping numbers, removing furniture, no external speakers. A Noise Impact Assessment should cover both, and should state the survey dates and the background levels measured rather than assuming a figure.

If you want an external area, deal with it head on in the application rather than adding it later. The rules that apply to outdoor seating for a restaurant apply in much the same way to a taproom yard, including the highway consent needed where tables sit on adopted footway.

Remember that a premises licence under the Licensing Act 2003 is a separate application to a separate committee, with its own four licensing objectives. Planning conditions and licensing conditions can end up inconsistent. Ask for the same terminal hour in both.

Deliveries, dray access and waste

A brewery generates awkward vehicle movements. Malt arrives on pallets or in bulk. Kegs and casks go out and come back. Spent grain leaves in a tipper or a trailer. Empty glass and cardboard build up quickly from the taproom side.

The council will want a servicing plan showing where a rigid HGV stops, that it can turn without reversing onto the highway, and that deliveries avoid the times when children walk past to school. Swept path drawings settle this argument faster than paragraphs of text do. Where the unit shares an estate road, check the turning circle against the largest vehicle your maltster actually sends.

Waste storage needs a designated, screened area with enough capacity for the collection frequency you have arranged. Undersized bin stores are a routine reason for an officer to ask for amended plans, which costs weeks.

What to submit for a mixed brewing and drinking use

For a change of use with modest external alterations, a typical pack is:

1. Application forms, location plan, block plan and existing and proposed floor plans with the brewing and taproom areas shaded and measured.
2. A Planning Statement setting out the use class analysis, hours, floor area split and management.
3. A Design and Access Statement where the works alter the appearance of the building.
4. A ventilation and extraction statement covering the boil vent and any food extract.
5. A noise assessment covering fixed plant and, where relevant, patron noise.
6. An odour assessment where residential receptors are close.
7. A servicing and delivery plan with swept paths.

Not every site needs all seven. A unit in the middle of a large industrial estate with no housing within 200 metres may need only the first three. A former shop on a high street with flats above will need all of them and a management plan besides.
