How noisy is your street?
See the government's estimate of road traffic noise at your postcode, and how it compares with World Health Organization guidance.
Keep the noise out
Windows are usually the weakest point for outside noise getting in. Well-fitted modern double or triple glazing, with good seals, can make a real difference. Our surveyor can look at your windows and talk you through the options.

Questions
Where do the noise figures come from?
From Defra's strategic noise maps for England (Round 4, based on 2021 traffic), published free for public use. They are computer models, not measurements at your house.
What do Lden and Lnight mean?
Lden is an average over the whole day, with evening and night noise weighted more heavily. Lnight is the average from 11pm to 7am. Both are in decibels (dB).
What does the WHO recommend?
The World Health Organization's 2018 guidelines recommend keeping road traffic noise below 53 dB Lden and below 45 dB at night.
Does it work in Wales?
Not yet. Wales publishes its own noise maps, which we have not added yet. This check covers England only.
