Noise Pollution FAQ
How is road and rail noise measured?
Noise is measured in decibels (dB). The UK government uses the Environmental Noise Directive to map road and rail noise above 55 dB Lden (day-evening-night weighted average). Properties above 65 dB are considered high exposure. For reference, normal conversation is ~60 dB and heavy traffic at 10m is ~85 dB.[1]
Does noise affect property value?
Yes — research suggests properties with high road or rail noise sell for 2–5% less than comparable quiet properties. For very high noise levels (above 70 dB), the discount can be larger. Noise is also a key factor in rental demand and tenant satisfaction.
What can I do about noise at a property?
Secondary glazing, acoustic insulation in walls and loft, solid core doors, and acoustic curtains can all reduce internal noise levels significantly. For persistent severe noise, residents can report to the local council's Environmental Health team.[2]
Should noise be disclosed when selling?
Significant noise issues (such as a known neighbour dispute over noise, or proximity to a flight path or motorway) should be disclosed on the TA6 form under environmental matters. Failure to disclose material facts can lead to legal claims after completion.
