Make better the air in your home or office

Our passion is creating and maintaining indoor environments where people can breathe fresh clean air and stay happy and healthy. This is a significant challenge in today’s world if you consider indoor air is often many times more polluted than outdoor air (up to 100 times more polluted according to the US EPA). In the UK, tightly sealed buildings and homes may be more energy efficient than older buildings but without adequate and effective ventilation plus other indoor environmental controls they can trap moisture, pollutants and microbes inside resulting in odour, mould and allergen build-up and causing discomfort and illness to the occupants.

Our history & industry background

Since 2013 Healthy Indoor Environments Ltd has been providing innovative solutions to indoor air quality problems of odours, condensation, mould, asthma, allergies, radon and VOCs in domestic and commercial environments. We provide a complete end-to-end service from initial discussion and survey through to industry compliant installation and after sales services. We service homeowners, landlords and trade intermediaries and we enjoy many repeat relationships and have carefully built an enviable reputation for quality and reliability. We have installed well over 3000 solutions since we started. We are CHAS accredited and members of the Radon Council and UK Radon Association.


Demand for affordable retrofit solutions and innovative air purification/disinfection products is increasing following the introduction of new legislation (Homes for Human Habitation Act – March 2019 ) and government initiatives such as the APPG Healthy Homes and Buildings and NICE Indoor Air at Home. This demand has recently spiked with the global coronavirus/COVID-19 emergency, especially for products like ours which are effective at reducing or eliminating infection transmission.


Our products offer marketing leading functionalities protected by patent, our expertise is sought after and our installations are second to none anywhere in the UK. In particular our air disinfection technology is uniquely capable of destroying coronaviruses and other organics instantly as they are emitted onto the air from breathing, talking, coughing and sneezing. It is a vital component in the fight to stop the spread of the coronavirus that causes deadly COVID-19 and protect public health.


How our products can help prevent the spread of the coronavirus that causes deadly COVID-19


The SARS-CoV-2 coronavirus that causes deadly COVID-19 is transmitted in the same way as common viral illnesses like colds and flu – either on minute water droplets that are emitted when people breathe, speak, cough or sneeze or when we touch a surface that has been touched by a contagious person. Considering hundreds of thousands if not millions of us catch these common illnesses every year it is vital that we do everything we can to prevent the spread of SARS-CoV-2 that causes deadly COVID-19.


Our patented air disinfection technology which is distributed throughout the entire indoor space is capable of destroying coronaviruses or any other organic instantly at the point they are emitted onto the air or touched onto surfaces. This effectively eliminates the ability for the virus to transfer from person to person in the air and on surfaces. The technology has been successfully tested against numerous organics and in a simulated sneeze test it destroyed 99% of all germs emitted at over 100mph before they had travelled 3 feet.


Our technology is the only active disinfection that is safe for humans in any indoor setting, whether it be at home, at home, at school or in a hospital, at the gym, in a car, bus, train, plane or ship. All other active technologies are dangerous (ozone generators, chlorine, flourine). It should be noted no passive technology can be used for air disinfection – an infected person in a room full of passive units will infect others before the units can purify the air.


Our technology disables the primary method of SARS-CoV-2 transmission. It will help protect NHS workers in the front line and save many lives. We stand ready at this time of national emergency to help.


The IAQ Market in the UK


The UK IAQ market is evolving rapidly. The drive to improve insulation characteristics in buildings (especially existing ones) to reduce energy consumption especially following the introduction of the 2008 Climate Change Act (free loft insulation, triple glazed windows near Heathrow), has resulted in a reduction of the quality of indoor air for millions of UK consumers. This is primarily because properties are built to or retrofitted with minimum compliance standards and in Part F Ventilation this means System 1 or Natural Background ventilation supported by extraction in wet areas – a strategy that generally underperforms and especially so during our cold winters leading to a build up of airborne contaminants such as humidity, allergens, dander, VOCs etc. which in turn negatively affects people’s health. In other words, the problem of indoor air is partly a consequence of the drive for improved energy efficiency in homes and there are 26 million existing homes in the UK that are likely to require some form of retrofit improvement over the coming years – a huge challenge on top of ensuring all new builds meet the new requirements. To give you some idea of the consequences of inaction in this area, a 2016 Royal College of Physicians report stated poor indoor air is associated with healthcare costs in the order of “tens of millions of pounds” and in 2015 Professor Hazim B. Awbi predicted that by 2050 there will be an 80% rise in people suffering asthma symptoms without action to tackle indoor air pollution.


We are familiar with all the current ventilation strategies of the current Part F regulations. In our experience only those strategies which offer a mechanical background (or whole house) ventilation process can be truly relied upon to deliver a permanent solution to indoor air quality that scales with occupancy/occupant habits. There are only two of these – System 4 (MVHR) is generally confined to the new/self build/PassivHaus space given it is generally not feasible to retrofit MVHR into an existing property – and Positive Input and/or Single Room Heat Recovery Ventilation that falls within the System 5 (Alternates) category and is the most suitable strategy for retrofit.


We are monitoring developments in this space very closely. We are a stakeholder of the All Party Parliamentary Group for Healthy Homes and Buildings, chaired by Jim Shannon MP and the NICE: Indoor Air at Home initiative. We are also a member of the UK Indoor Environments Group, the Radon Council and the UK Radon Association. In 2019 the Homes for Human Habitation Act was passed into law which gives tenants more power to force landlords to maintain their homes at an appropriate standard which will increase demand for services like ours, especially during winter when visually evident indoor air quality problems such as condensation and mould come to the fore. Further down the line we expect there to be changes to the various Building Regulations which will widen the scope of pollutant monitoring and ventilation response and policing of ventilation performance compliance following the example set by the recommendations of the Hackitt Review to prioritise building maintenance quality over cost efficiency following the Grenfell disaster.


Consumers in the UK are becoming more and more aware of the growing problem of IAQ and the direct effect it has on health and well being. Indeed IAQ problems are regularly mentioned in the national media these days. Every existing domestic home in the UK is a potential customer for our market leading retrofit solutions. There are currently approx 26 million domestic properties in England that may require a retrofit solution to improve IAQ and protect the health of the occupants. Of these approx 5 million homes are private rentals and 4 million are social housing. The current trend shows growth in the private rental market and contraction in available social homes with more and more private homes being rented through councils. The UK government has repeatedly tried to address the shortfall in UK housing stock by offering various incentives to the private sector following the 2008 financial crisis and recent claims suggest growth in new housing supply although Brexit has caused the industry to be cautious as economists predict a fall in house prices in the event of a disorderly exit. The UK government currently plans to build 300,000 new homes per year and new regulations relating to IAQ may be applied to these new builds but until changes to current regulations are made that prevent minimum current standards (ineffective natural background and extraction ventilation) the number of occupied properties requiring a retrofit solution will only rise.
