Are Our Engineers DBS Checked?

Yes. We know our engineers well, but you don’t that’s why we ensure all our field based service engineers are DBS enhanced checked so that you have peace of mind.

The Criminal Records Bureau (CRB) and the Independent Safeguarding Authority (ISA) have merged to become the Disclosure and Barring Service (DBS)

Working in schools, colleges, universities and healthcare environments, there should be arrangements in place to ensure that any contractors working in these premises with the opportunity for contact with children have been checked and it’s up to the head teachers and principals to ensure their obligations are met.

That’s why we made it easier for our clients by ensuring all our engineers have been checked and to the enhanced level which means we have taken this beyond basic and standard, and removes the need for supervision while onsite.
