In the first six months of 2012, just under a quarter of a million Cavity Wall Insulation installations were carried out under the Cavity Wall Insulation Self Certification scheme (CWISC) – a 36% increase in installations under the scheme compared to the first six months of 2011.

The CWISC scheme is operated and administered by the Cavity Insulation Guarantee Agency (CIGA) in association with the British Board of Agrément. The scheme provides homeowners with the comfort of knowing that work by registered contractors is not only covered by the CIGA Guarantee but complies with building regulations requirements.

Registered installers under the scheme must meet detailed technical requirements and are subject to regular independent inspections and surveillance of work. Under the scheme a certificate of conformity is sent to the homeowner shortly after completion of the installation.

Gerry Miller, chief executive of CIGA, commented, “Qualifying installations also receive the CIGA independent 25 year guarantee against defects in materials and workmanship. To date, CIGA has issued nearly five million guarantees, which, in conjunction with the certificate of conformity with building regulations, provides householders with complete peace of mind.”
