Feedback from hospitals

We were able to carry out remedial works, retest, and return outlets into use within a much shorter timespan than previously.

Paul Balaam, Senior Estates Officer, King's College Hospital NHS Foundation Trust


We wanted to make sure (Pseudalert) was as reliable, results-wise, as a lab. We took back-to-back samples, one going to the lab and one staying with us and Pseudalert. The results were impressive.

Phil Mitchell, Environmental Estates Officer, Oxford University Hospitals NHS Foundation Trust

These tests will afford us the opportunity to increase patient safety, reduce clinical downtime as well as reduce costs.
