Qualifications & Training
Employers may ask for GCSEs in Maths, English or Design and Technology. As there is not always a need to have qualification, experience of brickwork may be useful but not essential. A Level 2 BTEC First Certificate or Diploma in Construction may also be an advantage. To become a trained installer you would work under the supervision of an experienced installer and would take a number of short course offered by the product manufacturers. To become a fully trained installer can take between 3-6 months. You can also chose to work towards the SVQ/NVQ Level 2 Insulation and Building treatments (Construction) which cover units such as loft insulation, damp proofing and cavity wall insulation. Cavity insulation installers may also work on the Green Deal initiative which is a government project to make houses more energy efficient and cut carbon emissions. To undertake Green Deal work you will need to work for an organisation certified by a Green Deal certification body as meeting the standard in the Publicly Available Specification (PAS) 2030. Installers may take additional short courses and further training combined with experience which may result in progression within the job role and the energy efficiency arena.
