Contractor Accreditation

Contractor Accreditation is a mandatory requirement that contractors must achieve satisfactorily to gain accreditation and allow them to work in the UK. The requirements are specified in Appendix A of the OR and WRc-NSF conducts accreditation and re-accreditation in accordance with this methodology.

Lining Rig Assessment is a mandatory requirement undertaken by contractors to ensure spray-applied lining rig design and performance complies with the conditions of approval specified in the OR. WRc-NSF conducts Lining Rig Assessment in accordance with the methodology outlined in Appendix C of the OR.

Performance Audits

Performance Audits of lining rigs are conducted at the start of a contract or when a new lining rig is introduced on a contract. These audits are mandatory and are carried out in accordance with Appendix C of the OR and may be conducted at the contractor premise's or at a working site.

Routine Surveillance Audits

Surveillance Audits are conducted at the request of a Water Company and are principally a paperwork audit designed to ensure that contractors are fully complying with the appropriate requirements of the OR with respect to the maintenance of lining records. Audits are normally conducted at regular defined intervals varying from monthly to annually.
