Noise Check by Postcode — DEFRA Road Noise

Check road noise for any England postcode, live. Enter a postcode below and HouseCheckup samples DEFRA's official strategic noise map (Round 4, 2022) at that point — the modelled day-evening-night level (Lden) and the night-time level (Lnight) in decibels, framed against the WHO (2018) guideline levels of 53 dB Lden and 45 dB Lnight for road traffic. The model covers major road sources on a 10 m grid; railway, aircraft and local-street noise sit outside it, which is honest small print most noise checkers skip. Noise affects sleep, health and resale value — the £24.99 Complete report puts the reading in context for the exact address alongside flood, crime, EPC and the rest of the 15+ official-source checks.

Frequently asked questions

HouseCheckup uses DEFRA's strategic noise maps produced under the Environmental Noise Directive. These show modelled noise levels from road traffic, railways, airports, and industrial sources. Levels are shown in dB Lden (day-evening-night) and dB Lnight (night only).
Studies show that every 1 dB increase in road noise above 55 dB reduces property value by approximately 0.5–1%. Properties near major roads, railways, or airports are most affected. HouseCheckup's IQ Score includes noise as a factor in the overall assessment.
