Acoustic Underlay for Flat Conversions in Erith — common questions
Almost every London borough freeholder — including landlords managing Northumberland Heath blocks — asks for a minimum 17dB impact reduction (ΔLw). We fit underlays rated 18–21dB so you're the right side of the threshold, not sitting on it.
