Five accredited on-site testing services covering every regulatory requirement at the completion stage — air tightness, acoustics, ventilation, smoke control, and thermal imaging.
Most tests bookable within the same working week. Reports issued within 24 hours of completion. One point of contact throughout.
At completion stage, most new build developments require testing across several Approved Documents — air tightness under Part L, sound insulation under Part E, ventilation commissioning under Part F, and for apartment blocks, smoke shaft testing under BS 9991.
Most developers manage multiple contractors for these tests, each with their own scheduling, invoicing, and reporting. We handle all of them. A single site visit from our team can cover air testing, acoustic testing, and ventilation commissioning — reducing disruption to your programme and eliminating the coordination overhead.
Because we also handle SAP calculations, we know your design-stage air permeability target before we arrive. That means no surprises when the pressure test result feeds into your as-built EPC.
Every test your development needs to achieve Building Control sign-off at completion — coordinated, accredited, and reported within 24 hours.
Each on-site test maps to specific Building Regulation requirements. Understanding which apply to your development avoids last-minute gaps at completion.
"I have just used Build Envelope for Air Tightness Testing on our new build property and cannot thank them enough for the timely and professional manner in which the work was completed. I would not hesitate in using them again and would fully recommend them. Absolutely first class."
Air tightness, sound insulation, ventilation, smoke shaft, and thermographic surveys — all coordinated under one team across our core service areas. One point of contact from booking through to certification.
