Walkthrough: a cafe to a micro brewery taproom

A café to taproom change of use needs planning permission, because a drinking establishment has been sui generis since the Use Classes Order was amended on 1 September 2020. A café sits in Class E(b). A taproom where the main activity is drinking does not sit in any class at all, so there is no permitted change and no prior approval route. Add brewing on the premises and you have a mixed use that the council will treat as sui generis in its own right.

What follows is an illustrative walkthrough of that application on a mid terrace unit in a market town, with a flat above the neighbouring shop and a service yard at the rear. The scheme, the objections and the conditions are illustrative rather than drawn from a real decision.

The existing lawful use and the use class analysis

The unit had traded as a café for eleven years, open 8am to 5pm, with a small kitchen and six tables. Nobody disputed the lawful use. The applicant's first instinct was that a taproom was "just a café that sells beer", which is the mistake most of these applications start with.

The analysis the officer applied was straightforward. Where food sales are the primary activity and drinking is incidental, the use remains within Class E(b). Where the sale of alcohol for consumption on the premises becomes the primary activity, the use falls outside Class E and becomes sui generis as a drinking establishment. The brewing element, a 400 litre kit producing beer sold on site and to a handful of local pubs, is industrial in character and would sit in Class B2 if it stood alone.

So the application was made as a change of use to a mixed use comprising a micro brewery and drinking establishment, with the brewing floorspace and the customer floorspace identified separately on the plans. That framing matters later, because it sets the baseline for any future change.

One consequence worth stating plainly to any client. Once the use leaves Class E, it cannot return to a shop or a café without a further permission. The flexibility inside Class E is a one way door in this direction.

Why the proposal fell outside Class E

Three features put it beyond argument.

Alcohol was the main revenue line, with food limited to a short menu of sharing boards. Opening hours ran to 11pm Thursday to Saturday, well beyond café trading. And the brewing plant itself, with a mash tun, a boil kettle and four fermenting vessels, is plainly not retail.

The applicant had also considered claiming the brewing was ancillary to the taproom. That argument works where production is small and exists only to supply the bar. Here, around a third of production left the site in casks, which makes the brewing a separate primary use rather than something incidental.

Where a unit is being divided or partly retained in retail use, the analysis gets more involved, and access arrangements often decide the outcome. We work through a comparable split in a retail unit divided into two and the access problem.

Noise, odour and the environmental health position

The environmental health officer responded before the planning officer wrote the report, which is normal on this kind of application. Three issues came back.

Patron noise, including people drinking outside and dispersing at closing time. This was the one that drove the hours condition. The flat above the neighbouring shop is around 4 m from the proposed external seating area.

Plant noise, meaning the glycol chiller for the fermenting vessels and the cellar cooling. The applicant commissioned an assessment to BS 4142:2014+A1:2019, which compares the rating level of the specific sound to the background sound level at the nearest noise sensitive receptor. The initial design gave a rating level above background at night, so the chiller was relocated to the rear yard behind an acoustic enclosure and set back from the party boundary.

Odour from brewing, which is sweet and malty during the mash and boil rather than unpleasant, but persistent and recognisable. The council asked for an extraction and abatement scheme covering the boil vent, discharging at ridge height on the rear elevation. A Ventilation and Extraction Statement set out the duct route, the efflux velocity and the maintenance regime.

Two practical lessons from that exchange. Commission the acoustic assessment before you fix the plant layout, because moving a chiller on a drawing is free and moving one on site is not. And treat the brewing vent as a separate problem from the kitchen vent, because they operate at different times and at different temperatures.

Deliveries, waste and cellar access

Servicing is where small commercial applications quietly fail. The unit had no dedicated loading bay, and the rear yard was reached through a shared access 2.6 m wide.

The submitted servicing arrangements covered malt deliveries on pallets, roughly fortnightly, taken through the rear yard with a pallet truck. Cask collections twice a week. Spent grain removal, around 100 kg per brew, collected by a local farm. Glass and keg storage in a bin store at the rear, screened with close boarded timber.

The highway authority asked for two things: delivery hours limited to 7am to 7pm Monday to Saturday, and a condition requiring the bin store to be provided before the use starts. Both were accepted. The alternative, which the applicant resisted, was a full servicing management plan for a unit of this size.

Spent grain deserves a mention because it is the part clients forget. It is wet, it is heavy, and it sours within a day or two in summer. A collection arrangement written into the application is worth more than an assurance that it will be dealt with.

Hours, outdoor seating and the licensing overlap

Planning and licensing are separate regimes with separate tests, and a premises licence under the Licensing Act 2003 does not authorise a change of use. Running both in parallel is sensible, and it helps to keep the hours consistent between the two applications so that the council is not asked to approve different things.

The hours granted in this illustration were 11am to 11pm Thursday to Saturday, 11am to 10pm Sunday to Wednesday, with the external seating area cleared by 9pm throughout. The 9pm restriction on outdoor use did most of the work in answering the neighbour objections. Amplified music outside was excluded altogether.

Two further points on outdoor areas. A pavement licence for tables on the highway is a separate consent from the highway authority. And where the external area is within the application site, planning can control its hours and capacity, which licensing conditions alone may not achieve as cleanly.

The documents submitted

The application pack was deliberately short, with each document answering one objection.

• A Planning Statement setting out the use class analysis, the policy support for town centre uses and the response to the amenity objections
• A noise assessment to BS 4142 covering plant, with a separate section on patron noise and dispersal
• A Ventilation and Extraction Statement covering the brewing vent and the kitchen extract
• A servicing and waste statement, two pages, with a swept path sketch for the rear access
• A management plan covering last orders, dispersal, smoking area supervision and a named contact for complaints
• Floor plans distinguishing brewing, cellar, bar and seating areas, with areas in square metres

Where a conversion involves residential amenity for future occupiers rather than neighbours, the evidence set is different again, as a Class MA conversion refused on natural light shows. The full set of supporting document types sits on the planning report index.

The conditions negotiated

The permission carried eleven conditions. Six of them mattered.

The capacity condition was the one the applicant queried hardest and the one the officer would not drop. Its purpose is to prevent a small brewery becoming a production facility with a bar attached, which would be a different use with different servicing. Negotiating the number upwards at application stage is far easier than applying to vary it later.
