Is boundary noise monitoring a legal requirement in the UK?

It depends on the project and location. Boundary noise monitoring isn’t automatically required by national law, but local planning authorities often make it a condition for large or high-impact developments.

Sites working near residential areas, schools, or hospitals are more likely to need it. In some cases, councils specify monitoring under the Control of Pollution Act 1974 or as part of Section 61 agreements, which outline how noise will be managed.

Even when not strictly required, many contractors carry out monitoring voluntarily — it protects them from complaints and helps maintain a good relationship with the local community.
