Customer Charter & Feedback

We pride ourselves on our customer service and technical proficiency, therefore our testing is underpinned by the following promises:

  1. Testing conducted within a maximum of 10 days from request to attend site (unless the client has requested a later date). NB: Our typical lead times are less than 1 week.
  2. Air Test certificates issued within 1 working day of completing the testing. Sound Test Certificates issued within 2 working days of completing the testing.
  3. Testing conducted by a suitably accredited/registered test engineer in full compliance with the appropriate Standards and/or Building Regulations.
  4. If the tested building/unit doesn’t achieve the required result, all reasonable effort will be made to provide guidance on the underlying issues.
  5. Our staff will be punctual, professional and courteous at all times.
  6. Health & Safety, Environmental and Quality policies and procedures will be fully complied with at all times.

Failure to adhere to the above commitments will mean that any test visits affected will not be charged for.
