Construction noise in London is regulated primarily under the Control of Pollution Act 1974, enforced by local authority environmental health departments. Understanding the rules helps both homeowners commissioning works and neighbours affected by nearby projects.
Most London boroughs adopt working hour guidelines based on the London Boroughs construction noise model code. The typical permitted hours for noisy construction works are Monday to Friday from 8:00am to 6:00pm, Saturday from 8:00am to 1:00pm, and no noisy works on Sundays or Bank Holidays. These hours apply to externally audible noisy activities including breaking up concrete, using power tools, loading skips, and operating machinery. Quieter internal work — painting, fitting finishes, installing sanitary ware — is generally not subject to the same restrictions.
These are not statutory fixed hours. Each borough can set its own specific conditions, and some boroughs are stricter than others, particularly in conservation areas, high-density residential neighbourhoods, or for sites near hospitals, schools, or care homes. Particularly intrusive operations such as piling, heavy demolition, or road breaking may be subject to more restricted hours or may require advance consent.
The main enforcement tools are Section 60 and Section 61 notices under the Control of Pollution Act. A Section 60 notice is served by the council on a contractor whose works they consider to be causing excessive noise — it sets conditions on hours, noise levels, and methods. A Section 61 notice is issued when a contractor proactively contacts the council before works begin to agree an approved method and timetable of working. Obtaining a Section 61 notice before particularly intrusive works start is good practice for contractors on larger residential projects and provides protection against enforcement during the agreed works.
For neighbours affected by construction noise from a nearby project: if the works are occurring outside permitted hours, a complaint to the local authority environmental health team is the appropriate route. Most teams respond to complaints and will contact the contractor. Persistent breaches can result in fixed penalty notices or legal action.
For homeowners commissioning construction work: include working hour requirements in the building contract from the outset. Discuss the programme with your contractor before works start to identify which phases will be most disruptive, and communicate with your neighbours about the expected timeline. A neighbour who is informed and respected is far less likely to complain than one who first hears about the works at 7:45am on a Monday morning. 07359 872594 | contact@rcbgroup.co.uk | www.rcbgroup.co.uk
