Frequently asked questions about compartmentation surveys in Welwyn Garden City

What is the difference between Type 2 and Type 4 surveys in Welwyn Garden City?
Type 2 is a non-intrusive visual inspection of accessible compartment lines. Type 4 is intrusive — opening ceiling tiles, lifting access panels, inspecting risers and voids, and sampling flat or room interiors. Type 4 has become the expected standard for higher-risk residential buildings. For Welwyn Garden City sites, we confirm the exact recommendation during survey because building layout, occupancy and local authority or insurer requirements can change the specification.
What does the Building Safety Act 2022 require in Welwyn Garden City?
For higher-risk buildings, the Accountable Person must build and maintain a 'golden thread' of building safety information, including evidence that compartmentation and fire stopping perform as the fire strategy intends. By 2026 these requirements are fully enforceable by the Building Safety Regulator.
How is a compartmentation survey priced in Welwyn Garden City?
A non-intrusive Type 2 survey of a 2,000 m² office is typically in the £1,200–£2,500 range. Larger or complex buildings are priced on a per-day or per-square-metre basis after a brief scoping call.
