Where did it all begin?

The story of 1st Line Defence started all the way back in 2012, with our Managing Director – Brett Kinsman – and his vision of creating a UXO risk mitigation company that was a class above the rest.

The vision for 1st Line Defence was more than just offering UXO risk mitigation services; Brett wanted to create a company that invested in its people and the very best equipment and processes, with a strong focus of building great relationships with clients and suppliers.

The vision in 2012 was very straightforward:

  • Make construction sites a safer place for Commercial, Governmental and Humanitarian organisations to develop and operate in.
  • Build a team of talented individuals and provide opportunities for them to progress within a growing company.
  • Provide clients with a value for money service and sector leading customer service.
  • On 23 March 2012, 1st Line Defence invoiced its first client for a Preliminary UXO Risk Assessment and the company flourished from there.

Where are we now?

1st Line Defence really has grown since its humble beginnings.

In 2012, we started with a team of two staff and soon added our first two historical researchers. It was a time when everyone had to wear many hats and ‘muck in’ with every aspect of the business, and our friendly and practical approach was soon winning over new clients.

We are proud to have built a robust and diverse workforce of over 150+ employees who are trained to deliver the highest levels of customer service.

We have expanded our services to a wider global Land and Marine client base, whilst continuing to maintain the high quality project delivery 1st Line Defence has built its enviable reputation on.

We are the UXO risk mitigation company chosen by many organisations due to being UK Home Office Authorised and Police Licensed, and we hold numerous professional Accreditations & Memberships with industry leading Health & Safety organisations – safety is our top priority and you are in good hands.

1st Line Defence have the capabilities to assess and manage UXO risk on projects of all different shapes, sizes and scopes, and you can have peace of mind that our professionally-trained staff will support you throughout the entire project life cycle.

What does the future hold?

Our portfolio of work over the years has delivered a variety of services to over 4,000 clients, meeting all of their UXO risk mitigation needs and supporting our clients with UXO safety and awareness training, CPD courses and more.

We continuingly invest in our staff, equipment, processes, infrastructure and technology to provide our clients the most cost-effective UXO risk mitigation solutions in the industry.
