During these works, we found 1st Line Defence to be very professional, helpful and carried out the work to a high safety and quality standard.

Project Manager, VolkerFitzpatrick

May I say what a pleasure it has been working with your team from 1st Line. From Yourself and the team in the Office to the men who came to do the actual Survey, I have found you all to be very helpful and professional.

Project Manager, SIVA Group

The programme for this project is very tight, and the Detailed UXO Risk Assessment was instructed only shortly before ground investigation was due to commence. 1st Line Defence are to be commended for their rapid response and interaction when queries were raised regarding the initial site risk level. They also prioritised the project and gave proactive and timely advice, saving out Client costs in relation to UXO support services. Furthermore, the Detailed UXO Risk Assessment has been completed and issued very quickly (yet thoroughly) again giving confidence to the design team. I would have no hesitation in using 1st Line Defence as a preferred supplier and also recommending to others.

Director, BWB Consulting Ltd

During these works, we found 1st Line Defence’s performance to be exceptional. They were extremely professional and well-organised and performed all required tasks safely and efficiently. I would not hesitate using them on future projects and would definitely recommend them for similar works.

Project Manager, Bowmer & Kirkland

I have always found 1st Line to be highly flexible and accommodating to project changes. Their site and office teams are punctual and professional and have given me no reason to look for an alternative supplier.

Excellent service and speedy response. Appreciate your transparency and involvement and would be happy to use your services on any future developments we undertake.

Senior Design Coordinator, Galliford Try

1st Line Defence have now undertaken a number of pre-acquisition desk top studies for us. They have proven to be informative and instructive as to site conditions and the likely risks associated. We have also employed them on site to undertake site investigation of piling locations. They undertook these works efficiently, on programme and competitively. On their site performance to date, 1st Line Defence will continue to be our choice for UXO reports and site works.

Technical Executive, Crest Nicholson London

Just wanted say a huge thank you for sorting out the survey for us and fitting us in so quickly. The operatives on site have been absolutely brilliant over the last week and have kept us informed at every step of the way – even showing us how it all works. An absolute credit to you and your company. I wouldn’t hesitate for a second to use you again and indeed the lads would be top of my list. Please pass on our thanks once again to them.

Site Manager, Urban Splash

In a world where people are quick to criticise and slow to praise, please allow me to thank you and everyone involved in this project for your professionalism and flexibility in accommodating an ever-changing programme. In what was a logistically challenging and, at times, energy sapping ground investigation, being able to eliminate concerns over getting UXO engineers down to site (or cancelling) at the last moment was greatly appreciated by myself and all of the site engineers. Thanks again, and we’ll see you on the next phase.

Geo-Engineer, RSK

We are very pleased with the excellent quality of the reports that have been provided. The reports were turned around with some very short deadlines and the standard of work did not drop throughout. Again, thank you for the hard work that you and your team put into completing this work to the tight deadlines we set.

Geo-Environmental Technician, TSP Projects

1st Line Defence understands our business and requirements and have been able to assist in reaching practical and swift solutions to potential UXO threat.

We would certainly use 1LD again on future projects where UXO services are required.

Technical Director, CGL

Associate Director, GEA

In terms of feedback I’d rate the service as excellent across all categories. I’ve been genuinely impressed with the speed and quality at which both the reports were turned around (not to mention the fact that it’s been interesting to get to know a bit more about the sites’ history) and with the timeliness and ease of agreeing the nature and scope of works to be undertaken.

Project Manager, Archaeology

They were very helpful from the first contact, offering advice on methodology and approach to working on an awkward site. They were also flexible with our proposed programme of works and provided a quick response to our enquiry, mobilising an engineer to site at relatively short notice. Their UXO engineer was very professional, giving clear and comprehensive induction to the site works team. He was also accommodating, adjusting to a changing work programme at very short notice. His communication was excellent and he carried out work diligently. The office staff have always been very pleasant and happy to help where they can. I would happily recommend them and wouldn’t hesitate to recommend them again.

Senior Geo-Environmental Engineer, Geotechnical Engineering Ltd

The report has been very helpful – we appreciate the efficiency and professionalism with which 1st Line Defence have provided initial advice and the Express UXO report. Please pass on our thanks to your team.


Really impressed with the quality of service that 1st Line Defence offer. We set a bit of a challenge by asking for 24 Preliminary UXO Risk Assessments within the space of 2 weeks which 1st Line have risen to and have allowed us to remain on schedule with our site works. Very happy!

Geo-Environmental Engineer, M-EC

Site Manager, Watkin Jones Group

We had an emergency with a suspected WW2 device, which turned out to be a large cast iron bowl. 1st Line Defence were brilliant from start to finish. They took my finding very seriously and were able to visit the site straight away. They put my mind at rest and it reassured me that I had a professional on-site dealing with what could have been a very serious issue.

Site Manager, Grange Farm

I don’t think there was a single person from 1st Line Defence that wasn’t pleasant and professional. Considering the amount we shuffled you around site to fulfil our sequences we never heard a moan or complaint and targets always got hit. All dealings with the office were prompt and helpful, especially the early sign offs for piling procedures. I wouldn’t hesitate in recommending 1st Line Defence in the future.
