About Premium Spray Insulation

Over 27 Years of Trusted Insulation & Waterproofing Solutions for Domestic, Commercial, Industrial, Agricultural & Marine Projects

We are a family-run business with over 27 years' experience in spray-applied coatings, insulation and waterproofing. We serve domestic, commercial, industrial, agricultural, marine clients across UK & Europe-wide from our base in Oxfordshire.

No middlemen, just quality service

Unlike many in our industry, we don't subcontract. The same team that surveys your property specifies the system and carries out the installation — giving you consistent quality, transparent pricing and a single point of accountability.

Built around your project

From a single domestic loft to large agricultural, industrial and marine schemes, we tailor every solution using deep technical knowledge of the materials we install.

Accreditations and certification logos, plus profiles of our installation team, will be added here soon.
