What Our Customers Say

Cleveland Sitesafe have provided Fairburn Ings Nature Reserve with three anti-vandal steel hides built to our specification. They have proved to be very successful and stood up to attempted vandalism with little damage, they are also cheaper than similar sized wooden structures and a lot easier to keep clean and maintain.

Steve Wadsworth

Senior Warden, Aire Valley Reserves

We have had many Sitesafe products over a number of years. We find Sitesafe helpful with the initial design through to installation and their products have proved to be robust.

The addition of the two new buildings has significantly improved the grounds operation area, allowing us to fully to comply with our health and safety obligations. As well as meeting the legal side, the buildings offer first class garage accommodation to high value kit which would otherwise deteriorate quickly sitting outside.

Head of Grounds & Estates, National Football Centre

Since we opened the new visitor centre at Potteric Carr we have seen a significant increase in visitor numbers, people are amazed to hear the story of how the building was constructed and  also our staff  and volunteers love their new working environment.  Working with Joe  and his colleagues was a real pleasure and through practical and realistic discussions around project design and procurement, we were able to meet both  our budget and open on time.

" I was throughly impressed with the excellent communication with regards to our recent purchase of the new flammable storage cabinet.  The cabinet is of a very high standard and robust to last for many years to come. I would definately recommend Cleveland Sitesafe Ltd and they would be the first port of call for any future requirements."
