Excellence

Since our inception, we’ve prided ourselves on delivering excellence through the exceptional, client specific, environmentally friendly, service we provide. We recognise excellence as a measure bespoke to the expectations of each individual client, ourselves, and the industry as a whole. We seek to understand those standards and set about delivering a service that meets the high expectations we set for ourselves and in accordance with each individual client’s definition of excellence. 

Auditing is a significant part of what we do to ensure we deliver the agreed standards of excellence on our client sites. We regularly monitor client sites to maintain our high standards and ensure we meet the expectations of all our clients, achieving an average Quality Audit Score of 98% across our audited sites. 

After 5 years of continued service within The Royal Household, we were truly honoured to be granted HRH The Prince of Wales Royal Warrant in 2017. A warrant we have successfully maintained since and humbly believe is the ultimate mark of excellence.  

We are proud to operate complying with the fundamental requirements of ISO’s 14001, 45001, 9001 and 27001 which ensure best practice across our business.  

We are proudly an Investors in People Gold accredited workplace.  The gold ‘We Invest In People’ workplace accreditation is a three-year stamp of approval of our head office culture and work practices. We were awarded the gold accreditation after undergoing a rigorous assessment by Investors In People, who spent months reviewing our employee engagement, communication, and workplace culture, benchmarked against others in our industry, as well as all other IIP accredited organisations. 

GreenZone have been accredited and committed to implementing the Living Wage since 2013 when we became one of the first Recognised Living Wage Service Providers in the industry. We work hard to provide a fair and supportive workplace so that employees are empowered to perform at their best receiving a fair wage for the job they deliver. We work in close collaboration with all clients to implement the Living Wage across client sites.  

We are proud to be listed on the CIPS Corporate Ethics Register, as a sign of our commitment to safeguarding against unethical conduct in procurement and supply management. This accolade officially confirms that all of our staff involved in selecting and managing suppliers, are trained in ethical sourcing and adopt ethical values in how they source and manage suppliers.  

We have a Sitemark site certification that demonstrates that our FM service provision is delivered in line with the very best in the industry. Sitemark is the leading facilities management consultancy and benchmarking specialist in the UK, improving standards to create better work environments. 

IOSH is the chartered body and world’s largest professional health and safety membership organisation, with over 43,000 members worldwide. All GreenZone Operations Managers are trained in the IOSH Managing Safely Course.
