HL3 — Noise.

How City Of London actually applies HL3: who leans on it, where it bites hardest, and how often it's invoked. The policy text is the rule; this is the behaviour.

HL3 is a published City Of London planning policy. This page records where it appears in the council's published planning decisions.

What this policy is about

Policy HL3 requires new developments to assess and mitigate noise impacts on nearby land uses, particularly noise-sensitive areas like housing and schools. Developers must demonstrate no increase in background noise levels and incorporate noise-reducing measures. Existing activities are responsible for noise pollution, and developers are encouraged to enhance the acoustic environment.

Plain-English summary of the adopted policy text below. The full text is the rule; this is the gist.

The policy — as adopted

Noise

1. A noise assessment will be required where there may be an impact on noise-sensitive uses. The layout, orientation, design and use of buildings should ensure that operational noise does not adversely affect nearby land uses, particularly noise-sensitive land uses such as housing, hospitals, schools, nurseries and quiet open spaces. New noise-generating development should include suitable mitigation measures such as noise attenuation or restrictions on operating hours. 2. Any potential noise pollution conflict between existing activities and new development should be minimised, in line with the ‘agent of change’ principle. 3. Noise and vibration from deconstruction and construction activities must be minimised and mitigation measures put in place to limit noise disturbance near development. Developers will be required to demonstrate that there will be no increase in background noise levels associated with new plant and equipment. 4. Opportunities will be sought to incorporate improvements to the acoustic environment within major development. 5. When bringing forward major development proposals, developers should explore opportunities to enhance the existing acoustic environment. City Plan 2040 | Shaping the Future City fety Health, Inclusion & Saf Reason for the policy 3.4.0 The City has a complex, densely developed and intensively used built environment in which space is at a premium and where multiple activities occur in very close proximity. Therefore, the effective management of noise impacts applies to both development that introduces new sources of noise pollution and development that is sensitive to noise. 3.4.1 The main noise and vibration sources related to new developments in the City are: X Construction and demolition work and associated activities, such as piling, heavy goods vehicle movements and street works; X Building services plant and equipment, such as ventilation fans, air-conditioning and emergency generators; X Leisure facilities and licensed premises, involving noise from people and amplified music; and X Servicing activities such as deliveries, window cleaning and building maintenance. 3.4.2 Noise sensitive uses and developments in the City include residential developments, hotels and serviced apartments, health facilities, schools and childcare provision and certain open spaces. 3.4.3 Planning and licensing regimes operate under separate legislative and regulatory frameworks. The City Corporation will ensure that, as far as is possible, a complementary approach is taken between planning and licensing to enable consistency of advice and decision making. City Plan 2040 | Shaping the Future City fety How the policy works 3.4.4 The City of London Noise Strategy 2016-2026 sets out the strategic approach to noise in the City and the City Corporation’s Code of Practice for Deconstruction and Construction Sites provides guidance on procedures to be adopted to minimise the noise and vibration impacts of development. The use of planning conditions or obligations will be considered where this could successfully moderate adverse effects, for example, by limiting hours of operation. 3.4.5 Some major developments may have the potential to enhance the City’s acoustic environment, for instance by incorporating water features that can aid relaxation, help to mitigate sensory overload and help to mask traffic noise. More information about this can be found in the City Corporation’s Noise Strategy. 3.4.6 For noise sensitive developments, confirmation will be sought of appropriate acoustic standards at the design stage. The City Corporation will apply the ‘agent of change’ principle, meaning that the responsibility for mitigating the impact of noise will fall on the new development.
