Core services

            • Pulse Airtightness Test (Air Permeability Test) Measures how airtight a whole dwelling is
            • Background Ventilation Test (BVT) Room-level checks (bedrooms & habitable rooms) – avoids retrofitting trickle vents, air bricks, passive vents. Example: A 3-bed house = 4 tests (1 whole dwelling + 3 bedrooms)
            • Damp, Mould & Ventilation Assessments
            • Flow Rate Testing: Fan flow rates, door undercuts, trickle vents & passive ventilation – Part F compliance

Why Airtightness Testing Matters

            • Reduces heat loss & heating costs
            • Improves comfort & indoor air quality
            • Prevents condensation, mould & damp
            • Ensures Part L & PAS 2035 compliance
            • Increases EPC rating & property value
