National standards body celebrates up to 30 years of awards with us

We’re celebrating after receiving an achievement award from the British Standards Institution (BSI) following up to 30 years of successful accreditation (April 2024).

We were recently recognised for our decades of environmental, management and health and safety awards by the BSI, which is one of the world’s largest certification bodies.

Our Chairman, Graham Bentley, who initially instigated our Quality Assurance System in 1994, explains: “I am thrilled that we have achieved this incredible milestone, it shows our huge commitment to quality here.

“It’s a tremendous achievement, as there aren’t many companies that reach this landmark in their development. Our thanks go to our current Quality and Environmental Management System (QEMS) Manager, Will Hitch for his ongoing commitment to sustaining our high standards and our ongoing dedication to the environment. We have been accredited for Quality Assurance for 30 years and Environmental Management for 20 years.”

BSI produces technical standards for a wide range of products and services. It audits and provides certification to companies worldwide that implement measurable management systems.

We’re accredited by BSI to ISO 9001 Quality Management, ISO 14001 Environmental Management and ISO 45001 Occupational Health & Safety.

ISO 9001 helps firms likes us monitor and continually improve the quality of their products and services.

This standard not only streamlines operations but also emphasises the importance of constantly adapting to meet customer needs, thereby fostering a culture of continuous development and excellence.

Graham adds: “ISO 14001 is all about reducing our environmental impact through our operations, which not only contributes to a healthier planet, but also inspires customer and team trust and demonstrates our commitment to sustainability. It provides a framework through which we can measure and continually improve our environmental performance.”

ISO 45001 is all about prioritising the health and happiness of a company’s workforce to create a more successful, resilient organisation.

This management system standard enables organisations to provide safe and healthy workplaces by reducing the risks of work-related injury, as well as by continually improving their occupational health and safety (OH&S) performance.

How outdoor pollution impacts on IAQ

Although we all spend around 90% of our time indoors – working, resting and playing – we’re not immune from the contaminates that are swirling around outdoors.

In fact, outdoor air pollution plays a significant role in indoor air quality (IAQ).

Air exchange

Every time you open a window, door or ventilation slot, there’s continuous air exchange between the outdoors and the building you’re in.

Many studies have proven that particulate matter (PM) impacts on us and our health and wellbeing more than any other form of pollutant.


Indoor air exposure to fine PM originates mostly from outdoor air, especially in urban areas where the traffic can be heavy. This is the most likely source of contamination.

Heating & eating

The second most important source of exposure comes from the indoor combustion of solid fuels, where present, for cooking and heating.


The outdoor fine PM originates mostly from combustion sources, nearby and distant, in particular where the levels exceed rural backgrounds.

What is often not acknowledged is that in strongly polluted areas, e.g. heavy industry zones, city centres with heavy traffic, without air filtration, more than 90% of ambient PM levels monitored outdoors, occur indoors too.

Reduce PM exposure

Applying correctly selected, efficient air filters in ventilation systems can significantly reduce the impact of PM exposure and the burden of disease (hyperlink to March’s BoD blog) (BoD), which is a measure of life expectancy and the quality of life you can expect.

Top seven impacts on IAQ

Top seven impacts on IAQ

Ever wondered what impacts on indoor air quality (IAQ) the most?

There are seven major sources of poor ambient air.

These are the ones that affect the burden of diseases (BoD) the most.

Not sure what BoD is? Check out our previous blog on this here.

The seven sources of bad ambient air are:

• Ambient air quality
• Heating and combustion equipment/appliances
• Water systems, leaks, condensation
• Building site (radon from soil)
• Furnishings, decoration materials and electrical appliances
• Cleaning and other household products
• Building materials

Poor IAQ from the above can potentially impact on the health of you, your staff or any customers who come into your building.
