Level 3 NVQ Diploma in Insulation and Building Treatments

Accredited by ProQual

The NVQ Level 3 Diploma in Insulation and Building Treatments is the advanced qualification for experienced insulation and treatment specialists, and it is the route to the CSCS Gold Advanced Craft card. An NVQ is competence-based: you prove you can already work at an advanced level, assessed against national standards from your own workplace, with no exams. The whole qualification is completed remotely.

It is aimed at installers and technicians whose work goes beyond routine installation: surveying and assessing buildings, specifying and installing insulation and treatment systems, dealing with damp, timber and structural treatments, and managing quality across retrofit and energy efficiency projects.

This NVQ is awarded by ProQual and regulated by Ofqual (qualification number 603/6898/6). It is made up of core units covering health and safety, efficient working and resource handling, plus advanced units matched to the insulation and treatment work you do.

Completing the NVQ, together with a pass in the CITB Health, Safety and Environment test at the level for your occupation, lets you apply for the CSCS Gold Advanced Craft card. The CSCS Cards guide explains how the card, the qualification and the test fit together.

Not yet at advanced level? The Level 2 NVQ in Insulation and Building Treatments is the skilled worker route and the CSCS Blue card. Related specialist routes include Passive Fire Protection. You can also browse the full range of construction NVQs.
