Understanding Ventilation in Pubs and Restaurants

Why ventilation matters in hospitality settings

It’s fair to say pubs and restaurants are among the most unique commercial venues when we’re talking about adequate ventilation.

After all, when you factor in the heat and humidity from kitchens with odour from bathrooms or refuse areas, it’s easy to see why venues like these require well-designed and functional ventilation.
Good ventilation also positively contributes to energy efficiency and maintenance costs, too.

And all of that comes on top of the various regulations pubs and restaurants need to comply with…

For building managers, specifiers and installers, understanding the very specific ventilation requirements of pubs and restaurants is critical to the business providing a safe and high-performing environment for teams and customers.

Common ventilation challenges in hospitality

Pubs and restaurants provide installers and building managers with a particularly unique set of challenges, including:

Heat and humidity from kitchens

Cooking for as many as 20 people in a domestic kitchen offers a small glimpse at the sheer scale of cooking in a commercial setting, with the added heat and intensity of a commercial kitchen.

Commercial kitchens are, without doubt, one of the most intense sources of airborne pollutants in the hospitality sector.

Steam, smoke and heat from cooking are continuously generated during services and if this air isn’t extracted powerfully and effectively, it can have a huge impact on other areas of the venue, negatively affecting customer experience and comfort, but also the safety of staff.

And when it comes to building maintenance, condensation created from cooking heat and steam can damage things like plasterwork, ceiling tiles, paintwork and the overall finish of the venue, not to mention the potential human hazards that come with areas of damp.

All of which means increased maintenance and increased costs – all of which can affect the venue’s bottom line.

Odours and air quality in customer areas

Of course, odours are inevitable in hospitality venues serving food and drink.

And while the scent of a freshly cooked roast dinner can add a certain ambiance to a venue, over time these smells can become stale and accumulate – impacting customer experience.

This is a particular challenge for open-plan pubs or gastro venues, where directing airflow away from customer zones is an absolute priority for ventilation installers and building managers.

Spread of airborne contaminants

Away from the kitchen, pubs and restaurants can be havens for airborne viruses, dust particles and allergens – simply because of the close proximity of customers and high contact between those customers and the venue’s staff.

If indoor pollutants build up, this can cause discomfort, illness, irritation and even longer-term health impacts in some people.

Since the Covid-19 pandemic, the need for good air quality, circulation and filtration in hospitality venues has seen ventilation systems rise to the top of many hygiene lists among business owners and building managers developing new venues.

Building layout and ventilation constraints

Many pubs and restaurants occupy older buildings in the UK – and this can present installers and building managers with a separate set of logistical challenges.

In the case of Listed buildings, installation scopes can be made even more difficult.

Hospitality venues in older venues can mean:

• Basement kitchens
• Upper-floor restrooms
• Partitioned seating areas that restrict airflow

With neutral ventilation often insufficient in these types of buildings, particularly in areas without a stream of fresh air, ventilation systems must be adaptable, operationally quiet and compact in design to integrate with the building’s existing features. 

Regulatory and operational ventilation requirements

Ventilation in commercial hospitality settings must comply with several UK regulations:

Health & Safety Executive (HSE) guidelines

HSE guidance includes clear advice on maintaining air quality and temperature in commercial kitchens and advises that enclosed workspaces must have effective measures in place to provide sufficient fresh or purified air.

Building regulations, Approved Document F

Part F of UK Building Regulations stipulates requirements for fresh air rates in public buildings and workplaces.

These regulations include ventilation requirements on required extraction rates to manage moisture and pollutants from commercial kitchens.

The Workplace (Health, Safety and Welfare) Regulations 1992

These rules mean businesses are required to maintain a reasonable indoor temperature and adequate ventilation in staff working areas.

Work areas, such as a commercial kitchen, must also be kept clean from any build-up of grease, which could pose a fire risk.

Food hygiene legislation

The laws here dictate that commercial kitchens are adequately ventilated to remove heat, steam and odour, which helps to maintain clean work surfaces and reduce the risk of contamination.

Best practices for ventilating pubs and restaurants

Take a ‘zoned’ approach

Hospitality venues such as pubs and restaurants often have a variety of different areas – each with different airflow and ventilation needs.

Taking a ‘zoned’ approach as a building manager and installer and establishing these needs in a ‘zone-specific’ way can help ensure the venue not only meets its regulatory needs, but also avoids over-specification and high costs in lower-risk areas.

Balance extraction with fresh air supply

Extracting stale and polluted air will always be the first port of call for any ventilation specification.

However, a balanced ventilation system will also help to introduce fresh air through an intake system.

This helps to maintain adequate air pressure inside hospitality venues, as well as reducing noise and eliminating uneven temperature distribution.

If a natural flow of air isn’t possible, these systems can be introduced to draw in outdoor air and filter it – an extremely helpful process for urban venues or those with basement areas.

Prioritise critical areas

One of the keys to a successful ventilation installation in a pub or restaurant is prioritising crucial areas, such as:

• Kitchens: Commercial kitchens require powerful extraction to remove cooking fumes, heat, and moisture at source.
   
• Bathrooms: Hospitality restrooms can benefit from quiet but effective extraction to remove humidity and prevent condensation or odour build-up.
   
• Dining and bar areas: These areas need a comfortable airflow that does not create noticeable draughts or noise but maintains consistent temperature and freshness.

Choose energy-efficient ventilation equipment

As well as regulatory considerations, hospitality venues pushed to the limit by ever-increasing costs will require a ventilation installation with energy efficiency at the forefront.

Fans with low-watt EC motors can provide a similar performance to traditional ventilation fans but with a vastly reduced power consumption.

On top of that, systems that come with ‘demand controls’ where system operation is triggered by certain levels of humidity or occupancy, can help to optimise energy use during quiet hours.

Ensure access for cleaning and maintenance

System fans and ducts should always be installed with easy and effective maintenance in mind.

This means simple access points for cleaning and servicing, with grease build-up and the hygiene and fire risks that come with it a particular concern for pubs and restaurants.

With fire risk mitigation of huge importance, any ventilation system should be installed with fire-rated components.

Specifier and installer considerations

When specifying ventilation for pubs and restaurants, consider:

• Noise levels: Equipment should be low-noise in front-of-house areas to avoid disruption to customers.
  
  Aesthetic integration: Wall vent covers and ceiling grilles should suit the visual standards of customer zones.
   
• Durability: Fans in high extraction commercial kitchens and odour-persistent restrooms must be corrosion-resistant and easy to clean.
   
• Regulatory alignment: Ensure any system design and fan selection supports Building Regulations and local authority requirements.
   
• Installation flexibility: Window-mounted and wall-mounted options offer installation flexibility where ducted systems are impractical.

Effective coordination and communication between specifiers, installers, and building managers ensures that system performance for pubs and restaurants aligns with operational priorities and long-term maintenance demands of these kinds of venues.
