Fighting climate change

At Charterhouse group are working hard to fight climate change, from Zero or offset carbon suppliers, to making sure we can use the circular economy and deploy tools and services that are carbon or energy reducing compared to the current platforms and services. Some examples are SIP from a carbon neutral company, to recycling old handsets and PBX equipment, and looking to displace handsets for power savings by using softphones on laptops and PC's that are already consuming power over physical handsets that draw power in addition to devices already being powered.
We are empowering the business to look at this area closely and develop new policies and objectives as part of the business planning cycles. The Environment Policy of The Company is to ensure so far as it is reasonably practicable that its operations will be carried out with a commitment to protecting and enhancing the environment. As an office we know that we generate wastepaper products. However, as we strive for excellence in every aspect of our business, we are committed to minimising the environmental impacts of the business operation.
Our stated aims are to:
• Aim to continuously improve our environmental performance particularly with regards to our recycling and re-use of paper.
• Where possible we will use recycled or ecologically friendly paper.
• We will use 'waste' paper for notepads unless confidentiality may be compromised.
• Reduce our consumption of resources and improve the efficiency of those resources by printing double sided where practicable.
• Manage waste generated from my business operations according to the principles of reduction, re-use and recycling.
• Recycle all paper products, ink or toner cartridges.
• Comply as a minimum with all relevant environmental legislation as well as other environmental requirements.

Covid-19 recovery

Charterhouse is a growing group of companies, made up of several organisations from across the UK, we are continuing to employ staff from various backgrounds.
We have created new employment opportunities, will re-train staff that find themselves in a position that their role is no longer available and support employment of those who left employment by COVID-19. Locally sourced staff is no longer the norm, we are embracing the work from anywhere culture, our staff current and new will have the option to work from home or an office and no longer need to be employed from the local area however, where new staff would like to work from a local office, they will be given that opportunity.
Charterhouse will look to support businesses in the recovery from Covid by supporting them in new ways of working by implementing new technologies that support the new ways of working that decrees the need for travel and reduce the chance of infection rates. These new technologies and ways of working will support the recovery of our NHS and other organisations to levels pre-Covid. Our ability to bring together many technology stacks allows business to employ the right people as Charterhouse does and drive success through innovative ways of working.
Implementing new health initiatives within Charterhouse will support mental and physical health for staff, maintaining the hybrid working environment will stop the spread of the COVID 19 within our workforce allowing economic growth.
At Charterhouse, we feel strongly about being able to give back to our community. Each year we nominate an organisation doing great work with those in need and support them – both financially through our regular fundraising, and practically with our business technology expertise where they need help and support.

Tackling economic inequality

Charterhouse is growing, in the last 3 years we have purchased existing business to ensure group growth, these companies have brought growth to both their business and ours. These businesses are hiring within the group to ensure that we can continue organic growth to secure the future of staff and the wider group. Our ability to support SME’s is backed by our experience as an SME and one of a family run business.
Growth for our group comes from within and externally where your ability and attitude is more important than diversity or background. Employing the best person is key to growth, but more importantly equality. Our HR team look at the person and ability to carry out a role rather than disability or background.
Our goal is to continue growth from organic, ethical and people centric sales. We allow people to be themselves, to thrive, to learn and grow in their role or for future roles. Our staff where needed will be accredited via vendors and suppliers as well as industry standard qualifications needed, backed by time and support from Charterhouse to achieve these skills and accreditations.
Charterhouse are introducing more robust policies to promote a supply chain that is more sustainable and based on value than size. Smaller distributers and suppliers can deliver more value to the group, we can support smaller business by offering more opportunities to work with us and on behalf of our customers where we need 3rd party support or distribution.
We work closely with suppliers to ensure that we can deliver on contracts sustainable, ethically and securely, working to many ISO standards though to Cyber essentials and Cyber Essentials Plus, our accreditations provide a framework for growth, improvement and security.

Equal opportunity

We have a robust recruitment policy that drives equality from the top down.
Assessment criteria
Our aim at Charterhouse Group, will be to always recruit the person who is most suited to each role, whether the candidate is internal or external. We recruit solely on the basis of the candidate’s skills, capabilities and individual merit as measured against the criteria for the role. Qualifications, experience, and skills may also be assessed at the level that is relevant to the job.
Job descriptions and employee specifications
Before initiating the recruitment process, the responsible Hiring Manager must ensure that there is an up-to-date job description for the role with clear employee specification.
Advertisement of vacancies
It is our policy that all vacancies be advertised on the company intranet.
Equality, Diversity and Inclusion
We are committed to applying our equality, diversity and inclusion policy at all stages of the recruitment and selection process. We always carry out shortlisting, interviewing and selection without regard to an applicant's sex, gender identity, sexual orientation, marital or civil partnership status, skin colour, race, nationality, ethnic or national origins, religion or belief, age, pregnancy or maternity leave.
We will never exclude any candidate with a disability unless it is clear that the candidate is unable to perform a duty that is intrinsic to the role, having taken into account reasonable adjustments.
To prevent any candidate from being disadvantaged because of a disability, the individual responsible for communicating with applicants should ask each candidate whether or not they require reasonable adjustments to be made.
Interviews
Hiring Managers conducting recruitment interviews will ensure that any questions asked during the interview is not in any way discriminatory or unnecessarily intrusive. The interview will focus on the role and the skills needed to perform it effectively.

Wellbeing

Charterhouse take wellbeing seriously, not only do we ensure staff can work to a health work/life balance, but also can work from home when needed.
The further deployment of Yu Life gives staff a set of tools and challenges to maintain both body and mental health. Teams, individuals and friends all compete in daily and weekly challenges to keep body fit, and allows for mental hearth checks and challenges.
Annual company meetings and mental health first aiders all encourage staff to maintain mental health, but in a time of need they know they have help available.
In addition to the above, Charterhouse offer all staff added benefits, for example Private Health care, free flu jabs and eye tests, a day off on your birthday each year, all to help boost mind and body health.
