Our Testimonials

Contaminated Land Investigation

GB Oils have used OHES on a number of projects, in addition to any of those that are associated with insurance claims, and have always been very pleased with the high quality of the work produced, and the competitive pricing. They are always willing to work to whatever timescales have been laid out for them. We even had one project where the deadline was moved up by almost 2 weeks from what was originally conveyed in the instruction, and they worked very hard to get us as much information as possible to allow us to proceed with our internal project. The final reports followed shortly thereafter, still before the original deadline.

Tammy BrantleyHead of HSE, Certas Energy

We have been working with OHES for four years and in that time have developed an excellent relationship with them. We use them for environmental due diligence, environmental risk management and incident management and remediation services. We find all the OHES team to be professional, highly skilled, and enjoyable people to work with, who always make time for us when we need them. We look forward to continuing our relationship into the future.

The foundation of our business lies in R&D into Treatment Wetlands for water pollution control. Accurate lab analysis is essential to us, and we were looking for a company that could give that little bit extra… that company was OHES. OHES have a great team who have a clear understanding of water pollution chemistry and have delivered first class service and support over the past year by providing a unique cost effective service for on site sample collection, analysis and advice.

You guys did awesome to get all the peroxide in today... The boys deserve a big pat on the back, I know hard it is just being in those suits... Let alone doing anything in them!

Environment Agency OfficerEast Anglia

You have achieved so much for us with RRB, new Decoy and Corneys, and Old Decoy. OHES involvement has meant a real step change for the Great Fen – magnificent!

Project ManagerThe Great Fen Project

I am really grateful for your clear and pragmatic approach to all of this – no one wants to hurt bats but equally we need to get on with the project – so thanks for helping us find a professional (and speedy) way through this tricky issue.

Project ManagerRuby Tiger

I've taken some time to read through the report and am really grateful for the time and effort that I know has gone into putting it together and to the monitoring over the last year or so. The contents of the annual report, and the usual monthly report/scorecard are most useful, particularly to me as I manage things a little more distantly.

Environment AdvisorEast Midlands Airport

We are very pleased with the 2012 report and with the recommendations you have made to restore the lagoon which is scrubbing up. It will be an exciting project.

CouncillorNorfolk County Council

First of all I would like to say how impressed with this report I am! I was half expecting a rather rushed looking thing considering the timescale but it’s all presented very neatly! The figures are really useful and clear, so much better than the documents I’ve seen so far. You seem to have picked out the important messages from the documents you were given and it’s really good you acknowledge the discrepancies from these docs too.

Biodiversity OfficerEnvironment Agency

Having worked with OHES on wetland restoration projects involving Loch of Kinnordy and Vane Farm I can confirm that we are very pleased with the services offered. In both cases OHES worked in partnership with RSPB at all stages of the project including participating in meetings with the statutory agencies. The partnership extended from the start of the project with constructive debate on how to create a work programme that delivered objectives within the budgets set,through to end of project tweaking of reports etc to get the nuances of what can be quite complex pieces of work sorted out. In all cases OHES brought practicality and flexibility to the table and added value to what we were doing through their ecologically based approach.

Very impressed by the professional way this was handled, the two men cleaned making good around the tank. Excellent, also many thanks to the consultant he was most helpful and considerate at a very stressful time for me. Thank You.


I am aged 87yrs and all staff showed kindness and understanding in carrying out what must have been a demanding and difficult job, of which I am very satisfied.


I was very impressed with the quiet, competent way the job was tackled. The guys were always mindful, well mannered and kept me informed at all times. At no time was I inconvenienced, and it was a real pleasure to have them around.


We would like to express our thanks and appreciation for the way your personnel have dealt with the problems caused by the recent loss of oil from our tank. They have been most helpful, pleasant and conscientious throughout the whole process, from emergency removal of oil from our leaking tank, the subsequent investigations and excavations and finally the excellent restoration of the site.


A most professional service from office and onsight personnel. To date there are no issues and I would be most surprised if any were to occur.
