HR Assistant

With energy costs constantly rising and climate change affecting us all, low-carbon technology has an increasingly bigger role to play in the future of UK energy.

We’re here to ensure it’s a positive one.

MCS is a mark of quality. We create and maintain standards that allow for the certification of low-carbon products, installers and their installations, used to produce electricity and heat from renewable sources.

This is an exciting time to join MCS: in 2021, we reported exceptional growth and we now must continue to ensure we are at the heart of the UK’s drive to meet net-zero carbon by 2050.

Domestic energy is playing a huge part in achieving this target. However, deciding to invest in renewable energy remains a big step for many people; made more confusing by jargon and complicated financial models. MCS aims to cut through difficult language and complex processes as a way of ‘Giving people confidence in home-grown energy.’

Something ‘home-grown’ is something that matters to people personally – which they can take pride in. That’s exactly the feeling we want to create across the UK as we help more and more people embrace a home-grown energy future.

The MCS team has grown quickly over the last few years, so an exciting opportunity has arisen within our People and Culture function for a HR Assistant. Your day to day will be varied and busy and you’ll play an integral part in supporting almost 50 colleagues based across the UK.

The MCS culture including our values and behaviours are important to us and you will have the ability to help embed and deliver this further.

The role will involve undertaking a number of administrative tasks from supporting recruitment, corresponding with new starters and helping with induction, to maintaining employee records on our HR system and processing leavers.

You will have a friendly, approachable, positive attitude and be able to build relationships across the business. As well as being a confident individual with strong administration skills, you will also be highly organised and can handle multiple tasks.

This is a fast-paced environment, and you will need to be naturally self-motivated and able to use your initiative to ensure tasks are completed in a timely manner. Be flexible and adaptable to a variety of work tasks as necessary. You will be able to demonstrate continuous personal development, with the desire to continually learn and deliver HR best practice. It is essential that you are an effective communicator. Due to the nature of this role, confidentiality is key. You will have exceptional organisation, administrative and IT skills.
