LSI has long been recognised as one of the best employers in the construction industry.

We’ve been a Sunday Times Best Company To Work For since 2015, are gold accredited by Investors In People, and have been a finalist for the AJ100 Employer of the Year Award in 3 of the last 4 years.

We want our people to be happy, healthy, highly trained and highly motivated to deliver the quality design and committed service our clients expect from us. Increasing these four things in equal measure, for every one of our team, allows us to become stronger, achieve our ambitions and generate design opportunities that challenge, and allow us to explore our potential.

And so, we really look after our people, not just because of our legal obligations, but because we believe that they are our greatest investment.

Training and Development

Your training and development at LSI will start with induction and continue throughout your career with us. In fact more than 50% of our leadership team is made up of people who have come through the ranks at the Practice. To support you in your career development, you’ll have regular 1 to 1’s with an assigned mentor who’ll have the skills and experience relevant to your career path and a Wellbeing Action Plan, reviewed twice annually.

You’ll also be given an annual training budget, in terms of both cost and study leave, as well as the opportunity to attend regularly held CPD events, and our monthly Forum sessions covering topics such as Design, Technical, Digital and Sustainability.

We also place great emphasis as a business on the mental health and wellbeing of our teams, working alongside mental health charity Mind to provide our team with strategies and mechanisms to keep us well and resilient.

Regular team events include our Pitch&Putt tournament and our annual study trip, which in the last four years has taken us across to Stuttgart, Amsterdam, Glasgow and Budapest.

Why do we do it?

The benefits to us are clear, our clients tell us that they value our professional, collaborative, friendly and creative approach to projects and that our team is great to work with, and around 80% of our work comes from repeat business.

Employee retention and wellbeing statistics suggest we’re doing things right.  In the last 12 months, LSI’s employee turnover stood at less than 10%, significantly below the industry average. In the 2018 Workplace Wellbeing Index, run by mental health charity Mind, 92% of employees said LSI supported their mental health, and we were one of nine organisations nationally to be accredited ‘Gold – Achieving Excellence’.
