OSCAR Onsite is the UK's Leading Authority in Cavity Wall Insulation Extraction providing full training, Accreditation, NVQ qualification and Onsite clearance assessments.

We work collaboratively throughout the supply chain to deliver services to our clients and support them throughout their plan of works. By engaging with our clients during the whole supply and installation life cycle, we can help to achieve better delivery, quality workmanship and an ultimate client experience.

We work with all size firms with the aim to provide consistent delivery to a standard beyond reproach.

OSCAR Onsite was established in response to the growing cavity wall insulation crisis affecting homeowners, tenants, landlords and housing providers across the United Kingdom.

As reports of damp, mould, moisture ingress and failed cavity wall insulation installations increased, it became clear that there were no recognised occupational standards, methodologies or formal competency pathways dedicated specifically to cavity wall insulation surveying, inspection, extraction and clearance.

Recognising this gap, OSCAR Onsite developed the UK's only dedicated vocational qualifications in Cavity Wall Insulation Surveying & Inspection and Cavity Wall Insulation Extraction & Clearance in association with our member firms, helping to establish recognised competency standards for the industry.

Over the past decade, we have supported more than 250 contractor businesses through training, accreditation, technical guidance, compliance support and competency development, whilst assisting homeowners, tenants, housing providers and local authorities throughout the UK.

Today, OSCAR Onsite is recognised as one of the UK's Leading Authority in cavity wall insulation surveying, inspection, extraction, clearance, training and compliance, helping to raise standards, improve consumer confidence and promote better outcomes for properties nationwide.
