About Us

We are a family run Face Fit Testing business, based in Harwood in Bolton, who specialise in both quantitative and qualitative Face Fit Testing and Training.


We are BSIF fit2fit accredited for both options and cover the whole of the UK.  With many years experience in Face Fit Testing and a wealth of customer focused roles, we always put you first and make sure there is minimal disruption to your working day when carrying out face fit testing.


Even though we are based in the North west of England, many companies still find it more cost effective to use IESS for their face fit testing as we are highly efficient and flexible in our approach.


If you or your colleagues wear RPE, whether they are FFP Disposables, Half Face or Full Face Masks, then under HSE legislation they need to be face fit tested to ensure they fit the wearer correctly and are giving them the protection they deserve.


With every face fit test we provide, we also provide assistance and training on how to correctly maintain and don the RPE, thus ensuring your colleagues achieve the best protection possible.


We carry a huge range of RPE and we aren't tied in with one particular make and model, so will always have your best interests in mind.


If you would like some more information then please contact us here or request a free no obligation quote here.


We cover all business sectors and offer very competitive half and full day services.

Here at IESS, we offer both quantitative and qualitative face fit testing services, by a BSIF accredited technician.  Please contact us for more information, or a FREE independent, tailored quote, to suit your requirements.
