We had Richard conduct our fire warden training, it was really useful to have the same person who had carried out our fire risk assessment as it mean he knew our building inside out and the potential risks. It was an engaging and informative session which kept our interest. The team enjoyed the session and its great to feel confident hat all team members are now trained and fully equipped to handle a fire situation.

Excellent service, very professional, very good level of execution. I was in a very urgent need of Legionella audit, Piotr showed up the very day I called on his way from another job and I had the report within 5 working days. I was happy to pay a premium for a quick turnaround and work well done. I definitely recommend The First Principle Group.

Piotr and his team offered fantastic service for our legionella and fire risk assessment.
He was quick to respond to my initial enquiry and made the whole process very simple. His reports were extremely detailed and provided a clear action plan to help us pass our new dental practice CQC inspection.
I would recommend his services. Thanks Piotr
