Professional odour removal service using ozone generators
Bad odours within premises can be caused by a variety of things, such as cigarette smoke or mildew. These can linger long after the initial cause has been removed as odour particles in the air can embed into the upholstery and other porous surfaces which can stain fabrics and hard surfaces.
All environments such as offices, factories, retail outlets, commercial premises, healthcare establishments and food preparation areas can suffer from problems with malodours. It is important to not only remove the cause but to deodorise the surrounding area to help prevent a lingering smell.
We understand that these smells and bad odours are not only off-putting and unpleasant for your employees but also your customers. Our expert odour removal service uses ozone generators to remove malodours and are conducted by trained, professional technicians to ensure a safe and effective treatment.

There are many types of malodours and these are simply a byproduct of a chemical breakdown of protein molecules, bacteria and organic matter, as well as smoke particles. If left untreated, this breakdown will continue to occur and the odour will intensify the longer it is left, which can make it harder to contain as the surrounding surfaces and upholstery will absorb the smell. The cause of a malodour can pose a significant health risk, so it is important to identify the cause and clean the area.
Common causes of bad smells include cigarette smoke, mould, mildew and decaying biohazards such as urine and faecal matter.
Rather than simply masking smells with air fresheners, which is often ineffective and a waste of both time and money, our expert team will disinfect the area to remove the source of the odour.
Our ozone treatment then neutralises pungent smells, removing malodours and leaving a fresh and clean smelling environment. We use a measured amount of ozone, a gas that naturally destroys odours, cleaning the air and leaving treated areas clean.
Equipped with the necessary personal protective equipment (PPE), respiratory protective equipment (RPE) as well as specialist monitoring equipment, our trained technicians ensure the utmost levels of safety are maintained throughout our ozone treatment.
Our Rentokil Specialist Hygiene team are highly trained and experienced in odour removal. Our odour removal services will help you deal with the associated problems:

A professional odour removal service is a specialist treatment that removes bad smells from commercial environments by neutralising odour molecules at the source. Unlike air fresheners that only mask the smell, professional odour removal uses ozone technology and trained technicians to safely eliminate persistent malodours caused by smoke, mould, sewage, and more. It’s ideal for facilities such as offices, healthcare sites, retail units, factories, and food preparation areas.
Common causes of lingering odours include:
Odours are often caused by the chemical breakdown of organic matter, allowing bacteria and smell particles to be absorbed into carpets, walls, and air systems.
Absolutely. Persistent bad smells can negatively impact:
In some sectors like healthcare or food processing, lingering smells may also result in regulatory penalties or reputational harm. A permanent odour removal service helps businesses maintain a clean, compliant environment.
Air fresheners simply mask unpleasant smells with a fragrance. This does nothing to eliminate the source and can sometimes worsen indoor air quality. In contrast, professional odour removal uses advanced disinfection, sanitisation and ozone treatment to completely remove the molecules responsible for creating the bad smells, offering a long-term solution rather than a temporary fix.
Ozone odour removal works by using ozone generators to release O₃ gas, which breaks down and oxidises odour-causing particles. The gas penetrates porous surfaces and air spaces to neutralise smells at the molecular level. The process is safe when delivered by trained professionals, who isolate the area, monitor ozone levels, and ensure rooms are safe to re-enter.
Yes — ozone treatment is safe when performed by certified technicians using the correct PPE and monitoring equipment. The area should always be ventilated post-treatment and thoroughly tested to ensure it's safe for use. Rentokil Specialist Hygiene’s ozone odour removal service adheres to strict health and safety standards, using room-specific calculations to apply the correct ozone dosage.
Yes. We provide tailored commercial odour removal solutions across multiple sectors, including:
While basic cleaning or air fresheners may temporarily reduce odours, they rarely remove the root cause, especially in commercial or large-scale environments. DIY methods can also overlook hidden sources (like inside ducts or behind walls), and improper ozone use can be dangerous. A professional odour control disinfection service ensures safety, effectiveness, and long-term results.
