Who should take NVQ Level 2 Cavity Wall Insulation?

The Cavity Wall Insulation NVQ course is for experienced workers who meet the recognised occupational standards. The qualification is a validation of your skills and experience.

This NVQ is suitable for insulation installers who work on either new build sites or retrofitting insulation to cavity walls of domestic homes. The qualification is designed for installers who use wool, bead or foam materials. See the ‘Entry Requirements’ and ‘Assessment Process’ sections for examples of job tasks the assessment process covers.

The Onsite Assessment and Training (OSAT) route allows you to achieve your NVQ through workplace assessment at your own speed.

On achievement of the Cavity Wall Insulation NVQ Level 2, you will be eligible to apply for your CSCS blue card (Skilled Worker).

Entry Requirements

To undertake a Cavity Wall Insulation NVQ, you must meet the following criteria:

  • Minimum of three years’ experience working in cavity wall insulation
  • Must currently be working in the trade
  • Aged 19+

To ensure you have sufficient experience to complete the qualification, your NVQ assessor will carry out a pre-enrolment skills diagnostic in the following areas:

  • Cavity wall insulation pre-checks such as appliance and ventilation checks, smoke tests, flu spillage tests and locating external damp-proof courses.
  • Protecting the property of the customer.
  • Calibration testing.
  • Use of PPE and body harnesses.
  • Application of drill patterns.
  • Handling insulation blowing machines and repointing after each filling.
  • Clean-down and ‘housekeeping’.

Assessment process

We deliver Cavity Wall Insulation NVQ Level 2 through the Onsite Assessment (OSAT) route. We will assign you an assessor who will work with you for the duration of the course as you build a portfolio of evidence.

Types of evidence may include:

  • An onsite observation while you work, carried out by your assessor in your workplace
  • Photographs or videos of you working
  • References, employer endorsements or witness testimonies verifying your work as an insulation worker
  • Detailed job logs of work you have completed
  • A recorded professional discussion with your assessor either face-to-face or over the telephone. Candidates who have not already acquired ACOP certification in Gas Safety Awareness will be asked to demonstrate their knowledge of gas safety in a professional discussion.
  • Coursework covering the ‘theory’ of cavity wall insulation, and construction health and safety

During your NVQ, your assessor will support you in gathering workbased evidence for a range of skills including pre-checks, drilling and filling, and health and safety awareness.

Once your assessor is satisfied you have submitted sufficient evidence, our internal verification team will check your portfolio. They will then claim your NVQ certificate with City & Guilds.


Although workers can take up to six months or more to achieve their Cavity Wall Insulation NVQ, we find that most complete the qualification in 2 to 3 months.

Ultimately, the qualification will fit around your professional and personal commitments. Work towards it at a speed you feel comfortable.

There are several reasons you might take an NVQ, ranging from increased earning potential and career prospects, to gaining your CSCS card. See our short guide – Why Should You Do an NVQ?

Before starting your qualification, an assessor will be assigned to work with you and provide ongoing support.

DMR assessors are former construction workers with at least five years’ experience in NVQ assessment.

They hold an A1 or TAQA assessor’s qualification, a minimum of NVQ Level 2 in their occupational area and a blue or gold CSCS card.

We provide full training to all our assessors in supporting people with dyslexia or learning disabilities. If you need extra support and guidance with the written elements of your Cavity Wall Insulation NVQ, your assessor will draw up an assessment plan tailored to your needs.

An NVQ is a workplace competency qualification. As a competent cavity wall insulation worker, you will be expected to document your skills and experience through various types of ‘evidence’.

Your assessor will carry out at least one observation in your place of work. You will also complete coursework in your own time.

To achieve your qualification, you will not need to travel, there are no exams to sit, and you will not need to take time off work. Your assessor will provide support and guidance face-to-face, by phone and by email.

CITB-registered employers can claim a grant of £600 for every employee or contractor who completes an NVQ Level 2 to 7. You can find more information on the CITB website.

Government NVQ funding is available for construction workers who meet specific criteria. Please get in touch with us to find out if you are eligible for funding.

When you have completed your NVQ portfolio, our internal verification team will check it for compliance. They will then claim your certificate with City & Guilds.

Once we have received your certificate from the awarding body, we will forward it to you by recorded delivery. This process usually takes between two and four weeks.

To get your CSCS Skilled Worker card, you will also need to pass the CITB Health, Safety & Environment Test at your local test centre.

You can apply for your card by visiting www.cscs.uk.com/applying-for-cards. You will need to upload a copy of your NVQ certificate and have a debit or credit card ready to pay the £36 fee.

Yes, if you need a CSCS card while you are doing your insulation qualification, you can apply for the Experienced Worker card. You can request this card as soon as we have enrolled you on the NVQ (you will also need to pass the CITB Health, Safety & Environment Test).

To apply for the temporary card, we will email you your proof of enrolment which you must submit to CSCS.

You will then upgrade to the Skilled Worker card once you have finished the qualification.
