I have worked with the odour consultants at Silsoe Odours for several years. I use them for sampling and odour analysis in preference to other competitors, as I appreciate their flexible and pragmatic approach.

I have engaged Silsoe Odours for a series of odour investigations relating to ongoing legal proceedings with a neighbour at one of our sites. The team are always professional and willing to oblige. I would be happy to recommend their services.
