Pontcanna (Cardiff Daily) August 20, 2026 –A prominent Cardiff wine bar owned by one of Wales’ most high-profile chefs has entered a planning dispute with local residents over proposals to allow patrons to drink outside later into the evening.
As reported by Kieran Molloy of WalesOnline, oyster and wine bar Uisce, located on Romilly Crescent in the suburb of Pontcanna next to its sister restaurant Heaney’s, has submitted an official planning application to Cardiff Council requesting permission to extend the permitted operating hours for its outdoor roadside terrace.
Under current planning conditions attached to the venue’s original outdoor seating approval, customers are restricted to using the external suntrap terrace between 9:00 am and 9:00 pm. Owner Tommy Heaney has requested permission to extend these outdoor terrace hours to 10:00 pm from Sunday to Thursday, and until 11:00 pm on Friday and Saturday evenings.
The venue has additionally requested permission to keep the outdoor seating area open until 11:00 pm on Sundays that fall immediately prior to a Bank Holiday Monday.
The proposed extension has sparked opposition from surrounding property owners, who have submitted formal letters of objection to Cardiff Council warning that late-night outdoor alcohol consumption will exacerbate ambient noise levels in the residential street.
What are the specific concerns raised by Pontcanna residents?
Local homeowners living in close proximity to Romilly Crescent have voiced significant opposition to the planning application, arguing that the terrace already produces a noticeable level of noise during peak operating times.
As reported by Kieran Molloy of WalesOnline, one local resident stated in an objection letter:
“The outdoor seating area can become particularly busy during weekends and bank holidays. When a large number of people are seated close together it is natural for customers to raise their voices in order to communicate with one another over the surrounding conversations. However, because of the proximity of the seating area to residential properties, this creates a considerable level of noise which can be clearly heard from my home.”
Long-term residents on the street have echoed these concerns regarding proximity and sound pollution. As reported by Kieran Molloy of WalesOnline, another neighbour commented:
“My husband and I have lived at Romilly Crescent for 26 years and living opposite a large group of people drinking outside creates constant noise disruption.”
What noise mitigation measures has Uisce proposed?
In response to potential disruption and licensing concerns, the venue has submitted a formal noise mitigation plan alongside its planning application to Cardiff Council.
As reported by Kieran Molloy of WalesOnline, Uisce’s submission sets out specific operational measures designed to limit late-night disruption, which include:
- Enforcing a complete ban on playing music in the outdoor seating area after 9:00 pm on any day of the week.
- Installing highly visible signage on the outdoor terrace instructing customers to “respect our neighbours”.
- Delegating active supervision duties to staff members, who will hold the right of refusal to serve patrons who cause acoustic disruption.
- Implementing a strict ban on outdoor smoking and vaping on the terrace to discourage patrons from loitering outside late into the night.

Background of the Particular Development
The venue Uisce, which takes its name from the Gaelic word for water, was originally launched by chef Tommy Heaney in 2026 as a small-plates and wine bar concept adjacent to his flagship fine-dining establishment, Heaney’s. The location on Romilly Crescent sits within Pontcanna, an affluent residential area in west Cardiff known for Victorian terraced housing interspersed with independent cafes, pubs, and restaurants.
The relationship between commercial hospitality venues and local residents in Pontcanna has drawn increasing regulatory focus.
Cardiff Council and Shared Regulatory Services (SRS)—the joint environmental health service operating across Cardiff, Bridgend, and the Vale of Glamorgan—regularly monitor commercial noise pollution in mixed-use residential suburbs.
The application by Uisce comes amidst heightened scrutiny regarding outdoor seating licenses and noise control enforcement across the city’s suburban dining districts.
Prediction: How This Development Can Affect the Local Community
If Cardiff Council approves the application to extend Uisce’s outdoor opening hours, the decision will directly impact two primary local groups: nearby residents and local business operators.
For local residents living along Romilly Crescent and adjacent roads, extended outdoor seating hours could result in an increase in late-night ambient noise, particularly on weekends and warm summer evenings. Increased evening footfall may also heighten competition for residential street parking and increase local street activity past 9:00 pm.
Conversely, if the noise mitigation plan proves effective, residents may see structured controls placed on outdoor patron behaviour that did not previously exist in an explicit framework.
For local hospitality business owners and trade across Pontcanna, a positive planning decision could establish a notable precedent for outdoor terrace permissions along residential corridors.
Approval would allow Uisce to increase customer turnover during peak evening hours, potentially encouraging other suburban venues to apply for similar extensions. However, if the planning application is refused due to residential noise objections, commercial operators in the district will likely face stricter limits on expanding their outdoor seating operations.
