Brewery taprooms: Class B2 with ancillary sales

Brewing is a Class B2 general industrial use, and a taproom is only lawful without its own permission for as long as it stays properly ancillary to the brewing. Brewery taproom planning problems almost always start at that point. The brewery takes a unit on an industrial estate, opens the roller shutter on a Friday for tastings, and two years later the taproom has fixed seating for 60, a rotating guest beer list and a food van outside. That is a material change of use, and it needs permission.

The distinction is not academic. Once the taproom is more than ancillary, the lawful use of the unit becomes a mixed one, and the council assesses it against policies on amenity, parking and the loss of employment floorspace, none of which applied to the brewery on its own.

Why brewing sits in Class B2

The Use Classes Order 1987, as amended in 2020, puts industrial processes in Class B2 unless they could be carried out in any residential area without detriment to amenity, in which case they fall within Class E(g)(iii) as light industry. A commercial brew house rarely passes that test. Wort boiling produces odour, spent grain has to be stored and removed, cleaning chemicals are used at volume, and deliveries arrive on rigid lorries.

Very small operations do sometimes sit in E(g)(iii), particularly a nano brewery behind a shop with no external plant. If you are relying on that, get it confirmed rather than assumed, because the whole regulatory position rests on it.

There is no permitted development route from general industrial use into a drinking establishment. Pubs and bars became sui generis in September 2020 and nothing in Part 3 of the General Permitted Development Order 2015 delivers you into that category, so a taproom that crosses the line needs a planning application.

When a taproom stops being ancillary

Ancillary use is a question of fact and degree, judged on the functional relationship between the two activities and the subordinate scale of one to the other. There is no percentage in the legislation. Officers look at a cluster of indicators, and so should you before you commit to a fit-out.

• Floor area given to the public compared with the production area.
• Opening hours, and in particular whether the taproom trades when brewing is not happening.
• Whether the beer sold is your own product only, or whether guest beers, wines and spirits now form part of the offer.
• Whether the taproom is advertised as a destination in its own right, with ticketed events and bookings.
• Whether staff are employed for the bar alone.
• Whether customers come by car in numbers the unit was never designed for.

A tasting room open two evenings a week, seating 20, selling only your own beer, with no external seating, is a reasonable ancillary claim. A bar open Thursday to Sunday, seating 80 inside and 40 on the yard, with a guest tap list, is a drinking establishment that happens to share a building with a brewery.

Describe it honestly in the application. A description such as use of the unit for brewing (Class B2) together with an ancillary taproom, with hours specified, gives the council something it can condition. Vague descriptions get refused or conditioned harshly, because the officer has to control the worst case your wording allows.

Odour from the brew house and the spent grain

Odour is the issue that generates complaints from residential neighbours and the one environmental health will ask about first. Wort boiling produces a sweet, cereal odour that carries, and spent grain left in a skip through a warm weekend can turn sour quickly.

The evidence the council expects is a written assessment of the source, the release height, the nearest sensitive receptors and the controls proposed, prepared with reference to the Institute of Air Quality Management's odour guidance. An Odour Assessment is one of the report types councils usually expect a suitably qualified author to prepare, and professional review before submission is strongly advised where the nearest housing is close or downwind.

Practical controls carry more weight than modelling on a small site: discharging the copper vent above roof level and away from housing, moving spent grain into a sealed container the same day, agreeing a collection frequency with the farm that takes it, and keeping a complaints log. Statutory nuisance under the Environmental Protection Act 1990 runs alongside planning, so a condition is not the end of your exposure.

Noise, deliveries and the yard

Two different noise problems sit in one application. Plant noise from the chiller, the compressor and the extract is assessed under BS 4142 against the background sound level, and that is straightforward engineering. Customer noise in an external area is not a BS 4142 matter and cannot be modelled the same way, which is why councils manage it with conditions instead.

Expect proposed conditions on the hours the external area may be used, whether amplified music is permitted outside, when tables and chairs are cleared, and the closing time for the yard as opposed to the building. A Noise Impact Assessment should cover both strands and say plainly which is being managed by design and which by management, and its author should be suitably qualified because the council will ask for methodology and measurement periods.

Deliveries are the third strand. Malt arriving at 6am on an estate that backs onto houses will generate objections even where the brewery is lawful, so set delivery hours in the application rather than leaving them to a condition someone else drafts.

Licensing is a separate consent

A premises licence under the Licensing Act 2003 is not planning permission, and planning permission is not a licence. The tests are different, the decision makers are different and the two can reach different answers. It is entirely possible to hold a licence until midnight and a planning condition requiring closure at 10pm, and the condition wins.

Apply for both, and keep the hours consistent between the applications. Licensing committees often ask what the planning position is, and an inconsistency invites a condition tightening one to match the other.

Parking on an industrial estate at weekends

Industrial estate parking is designed for weekday employees, not Saturday night customers. The question the highway authority asks is whether the taproom generates demand at a time when the estate is otherwise empty, in which case shared use may be acceptable, or whether it clashes with neighbouring units that trade at weekends.

A short Transport Statement with an honest account of customer arrival patterns, the walking route from the nearest bus stop, cycle parking and any shared use agreement usually does the job for a taproom of this size. Where the estate roads are private, check the lease before you promise anything about parking you do not control.

Taxi and ride-hailing pick-up is the detail that gets missed. Name the pick-up point on the plan, because otherwise it becomes the pavement outside the nearest house.

Putting the application together

The pack for a taproom application is short but specific: existing and proposed layouts showing the split between production and public areas, an external areas plan, an odour and ventilation position, a noise position, a transport statement, and a management plan covering hours, dispersal, waste and deliveries. Operators who also run a soft play or family session model should read our note on soft play centres and their use class, parking and noise conditions, and anyone dealing with an extraction objection will recognise the pattern set out in beauty salons and nail bars: extraction and hours.

One honest uncertainty. Where the ancillary line falls on a particular site is a judgement, and two officers in neighbouring authorities can reach different views on the same floor plan. Pre-application advice costs little relative to a refused application and an enforcement notice, and it produces something in writing you can point at later.
