Our People.

“We employ all the latest building techniques, but our clients constantly tell us that it’s the people we employ that elevate the quality of our service beyond others. I’m honoured to be a part of the team”

Chris Lindsey, Owner

We know that our greatest strength comes from our people and we all understand and feel that the whole is greater than the sum of its parts, which makes our community what it is.

We share in our triumphs and we’re together in our challenges. We learn from each other and we work to improve the lives of our Clients and ourselves. The decades of immense knowledge and experience that is shared, steps us apart from others.

“One of the reasons I enjoy working for the Lindsey Group is the team work. We are a team on site & in the office, we work together to deliver great customer service. There is a nice balance of working hard in a relaxed atmosphere. Through the highs & lows at work & in your personal life, you’re supported through it all which is not always something you find in a work place. You’re encouraged to be the best you can be & the goals are motivating.”


Progression, training, support and profit sharing are all fundamental parts of the support the team receive, which pushes us forward during these exciting times.

All these are based on the foundational values we cherish, being honest and respectful throughout everything we do together as a team and in what we deliver to our Clients.

How We’ve Helped Our Clients

We are constantly looking for ways to improve our processes in order to provide an unparalleled service that exceeds expectations each and every time. Don’t just take our word for it though – read through some of the testimonials that our clients have written to learn more about their experiences at Lindsey Group.

All of the team from admin to engineer are polite, helpful, supportive and resourceful and reassure you that your issue is a important to them. As a Facilities Manager, operating managed service business centres, using Lindsey Group is very reassuring to me, I am confident that we have the expertise of their long-standing engineers. I would recommend them to any Manager for both reactive and proactive maintenance. We all know that reactive maintenance requires a swift response, these can be stressful and having Lindsey Group’s support has been invaluable.


Facilities Manager, Colbea

I find the level of service from both the admin and engineer teams to be excellent. Communication is always efficient and clear, work is completed in a timely manner and to a high standard, and certificates are delivered on time as well. Finding reliable and readily available contractors can be tricky, but your team always go above and beyond and it’s so reassuring to know that I can call on them, even at short notice, for all manner of jobs.


The National Trust

The Trust has a long association with Lindsey’s. They provide us with both routine maintenance and an effective and efficient out of hour’s service. I find both their service engineers and the senior team to be helpful and responsive. We provide a service for very vulnerable people and Lindsey’s recognise the importance of providing us with consistency in the people who work with us, all of whom demonstrate that they understand and are sympathetic to our elderly and frail client group. Lindsey’s have also worked closely with us on a number of refurbishment projects and are our preferred heating installers since 2007.
