This I find difficult to understand. At my sons house to be here to help with the children whilst some (quite a few) carpets are being fitted. They have followed SCS instructions and removed all the furniture. They were told that this was all that was required after having asked for confirmation of this. Carpet fitters eventually arrive after having a few cancellations. They stated that they could not remove the carpets due to CROSS CONTAMINATION and as such would be well within their rights to leave. When my daughter in law suggested calling SCS they stated that they would just be told to leave. HOWEVER....... They could remove the old carpets for an extra cost....... So much for CROSS CONTAMINATION...... IT IS OBVIOUSLY RENDERED INACTIVE IF YOU PAY EXTRA MONEY .......
